The story of IWI US begins in 1933 when Israel Military Industries (IMI) Ltd. began firearms production in Israel under the British Mandate. In the late 1950s, IMI began collaboration with the Israel Defense Forces (IDF) with the goal of developing the small arms systems based upon the demands of troops fighting in urban areas and harsh arid terrain of Israel. IWI arms are also a function of the harsh political environment in which Israel finds itself. Not only do implacable enemies surround Israel, but they also exist within Israel’s own borders. In 2005, the Israeli government decided to spin off and privatize the small arms division of IMI, and Israel Weapon Industries (IWI) Ltd. was born. IWI US, Inc. is a proud member of the SK Group. This includes IWI Ltd., IWI US, Inc., Meprolight Ltd. (electro-optical systems), Camero-Tech Ltd. (through-the-wall sensing systems), Israel Shipyards Ltd. (ship manufacturing and repair) and Uni-Scope Optical Systems Ltd. (optical periscopes, riflescopes and binoculars).

Personal defense handguns have certain basic tenets that are simple to list, yet complex and somewhat nebulous in achieving. Such things as trigger pull, ergonomics of operating controls, sights, capacity and “carryability” all contribute to overall feel of a handgun. One thing that is not negotiable is reliability no matter the operating conditions.

Choice is what makes the free market economy so tantalizing. What am I talking about? Sure, there are existing polymer striker-fired pistols on the market, but that does not stop other companies from introducing their take on the topic. All of this leads to productive competition with the consumer benefiting. IWI’s reputation lends credence to any new introduction on its part; especially its first foray into the crowded striker-fired polymer market space. When the IWI MASADA arrived in the U.S., the opportunity to test and evaluate was seized upon. The Israeli take on the striker-fired handgun is worth exploring.

The MASADA

The MASADA features fully ambidextrous controls, and well-thought-out ergonomics provide for natural and instinctive aiming. Three interchangeable backstraps allow for end-user tweaking for the best fit. The MASADA’s frame is made of high-strength, impact-resistant, fiberglass-reinforced polymers. IWI has conducted extensive testing to make sure the MASADA can function and endure in any environment.

The MASADA trigger is set at a 6-pound pull weight. Trigger snobs will wrinkle their nose at this. The MASADA is a personal defense/service weapon, not a competition piece. The MASADA trigger pull is clean with no crunching or grinding. A graph of the trigger pull would be interesting as there is something about it that positively resists words. Reset in length is minimal with positive tactile feel. This translates into a handgun that can send rounds downrange rapidly and accurately.

Sights on the MASADA are the standard-issue, three-dot affair. If the end user wants to replace these, the MASADA uses SIG SAUER pattern-cut sights; thus, aftermarket P320 or P226 sights will work giving customers plenty of options, including extended height suppressor sights. What am I talking about? The MASADA has the ability to mount various red dot sights straight from the factory without having to resort to a gunsmith to mill the slide. This is accomplished via four adapter plates that accommodate Trijicon RMR®, Vortex VENOM, Leupold DeltaPoint® Pro and SIG SAUER ROMEO1™ miniature red dots. A blank plate covers the rear receiver when no red dot is being used. The plate mates seamlessly to the slide. A packet of screws and an instruction manual are included with the MASADA, explaining red dot mounting procedures. Having a slide milled to a specific red dot sight limits your flexibility in choosing various red dots. The IWI is a solid alternate method.

The miniature red dot concept seeks to answer how best to enhance the handgun. The solution is the same as the one most users had already opted for with their rifles—add a red dot sight. The explosion of factory-ready, red-dot-compatible handguns is proof the industry has heard customer demands. IWI integrated this into the MASADA. It will be interesting to see how long before a threaded barrel option arrives.

The IWI MASADA arrives with two 17-round magazines; 10-round magazines for those living in restrictive states. Well-made front and rear serrations ensure a solid purchase when manipulating the slide. The 4.1-inch, cold-hammer forged, 1:10RH barrel has polygonal rifling. Weight when empty is 22 ounces. Ambidextrous slide lock levers and magazine release buttons are standard. The polymer frame features a MIL-STD 1913 accessory rail for lights/lasers.

The IWI MASADA disassembles quickly via locking the slide open and rotating the takedown lever downward on the frame freeing the slide from the frame. There were no tool marks evident and no lateral play in the slide’s fit to the frame or barrel to slide. The barrel locks up tight when in battery. The MASADA operates via a modified Browning’s locked breech short-recoil method with a single locking lug milled above the barrel’s chamber. The MASADA’s slide mass and shape are engineered to aid in increased muzzle control for double taps or longer strings of fire. A low bore axis relative to the shooter’s hand allows for a very stable sight picture no matter how many or how rapid rounds are fired.

Test and Evaluation

Considering that the MASADA’s design is intended as an everyday carry (EDC) handgun, it was decided to dedicate some time evaluating the IWI MASADA, working around vehicles, breaching facades, door entries and other CQB activities. L.A.G. Tactical, Weber Tactical, ANR Design and CrossBreed have holsters in the product lineup to accommodate the MASADA. A L.A.G. Defender holster was chosen for use at Echo Valley Training Center’s onsite Hesco Shoot House and 360 Range, which were ideal test locations. A premium is placed on a quick handling accurate handgun such as the MASADA with multiple rounds fired in quick succession—the norm to put a target down. The natural pointability of the MASADA comes into its own in this realm.

A variety of 9mm loads were tested with the MASADA including Federal Syntech and HST, Hornady XTP and Black Hills Ammunition JHP. An ammunition can featuring a smorgasbord of random brands and types was also used. Loads fired spanned 115 to 147 grain with hollow-point and FMJ bullet types. Significantly, no malfunctions were experienced while test firing over 350 rounds with the MASADA.

The IWI US MASADA is the answer for the concealed carry practitioner wanting a handgun with maximum capability and adaptability.

The IWI MASADA produced 2- to 3-inch groups at 25 yards when fired from standing, unsupported positions. The MASADA’s trigger was a positive, keeping in mind it is a service handgun. A negative encountered was the profile of the magazine release button. The MASADA had to be shifted in the hand for the thumb to comfortably drop a magazine. This is one of the nebulous items of handgun design; someone with a different hand profile may have no issue.

A Trijicon RMR was mounted on the MASADA. The polymer mounting plate was initially a concern. Plastic will never instill the same sense of sturdiness as metal. However, the plate acts more as a spacer than a mount with the screws installed down into MASADA’s milled slide. One note of advice is to install after-market, co-witnessing iron sights if contemplating carrying the RMR-equipped MASADA as a personal defense weapon. This is easily achievable thanks to the MASADA’s compatibility with SIG SAUER sights. The adding of heightened suppressor-style iron sights acts as both back-up sights and quickly fixes the shooter’s eye to the red dot stationed above the front post. Both eyes open is strongly suggested; it is a must to get the most out of the red dot concept. Point shooting with the MASADA is still very possible via using the red dot’s window as a ghost ring—albeit a large ghost ring—if forced to react spontaneously to a threat. The advantage of using red dot sights in the competition environment is well-known.

The RMR-equipped MASADA came into its own, and it was hard to resort back to only iron sights. Groups with the IWI MASADA were markedly smaller with a red dot mounted versus iron sights. This statement became more true as distances increased. The ability to consistently ring a steel man popper target at 50 yards, even out to 100 yards with regularity, was validation why red-dot equipped handguns are here to stay.

As many “maturing” shooters can attest to, the single-focus plane of the red dot is simpler to shoot accurately than coordinating front and rear sights. Shooters can now do as nature intends for them to do, focus on the threat with both eyes open—all simply because the concept uses the eyes in a more normal manner.

The IWI MASADA’s ergonomics and handling characteristics were quickly appreciated. The grip frame with enhanced texturing and overall balance of the handgun minimized felt recoil. The key point with the MASADA is that it is eminently adaptable to individual carry needs thanks to the red dot mounting system. The IWI MASADA arrives ready to go right out of the box. The ability to use the MASADA as an everyday carry handgun is what sets it apart from other endeavors incorporating red dots on pistols.

New Coating

Federal’s original impetuous with Syntech ammunition was to service the burgeoning competition circuits’ appetite for ammo. Federal decided this was an opportunity to assist shooters who did not want to reload in order to keep up with ammunition demands experienced during practice and competing. Federal’s goal was to forego the typical copper jacket via polymer bullet coating. As the multiyear research proceeded, other aspects were added to Federal Ammunition’s product goals. This included not only reducing fouling and extending barrel life via the polymer bullet coating, but also making a cleaner burning propellant and Catalyst™ lead-free primer. Syntech Range ammunition included 9mm 115 grain (GR) and 124 GR; .40 S&W 165 GR; and .45 ACP 230 GR. In 2018, Federal expanded beyond its initial 2017 Syntech Range offerings with Match, Defense, PCC and Action Pistol loads. Calibers include 9mm, .40 S&W and .45 ACP. Each load category, i.e., Range, Match and Defense, is color-coded for quick reference and contains Federal’s exclusive Catalyst™ primer, making Syntech perfect for indoor ranges.

While still a lead core, the Syntech bullet is coated, not copper-jacketed, with a polymer shell. The polymer coating eliminates metal-on-metal contact in the barrel. The result is softer, smoother shooting, less friction, heat and barrel wear. According to Federal Ammunition, Syntech ammunition generates about 12% less friction and about 14% less heat than typical jacketed rounds. Start multiplying this by strings of fire, and the significance is evident. This translates into less required cleaning and better overall reliability in a heavy-volume-use handgun. Not hard to see why shooting sport competitors are embracing the Syntech concept.

Another benefit of the Syntech coating is less chance of injury from jacket fragments after impacting steel targets or solid backstops. The Federal Syntech practice loads (Range and Training Match) are especially suited for engaging steel at close range with minimal chance of bullet spalling/splashback. According to Federal, recoverable fragment weights with Syntech ammo are about 51% less than what is common with FMJ bullets between 5 yards and 15 yards from the impacted steel. Past 15 yards, the comparison disparity becomes more pronounced with Federal Premium Syntech producing 91% less weight in recovered fragments. While not the equivalent of true frangible ammunition, Federal Syntech is a significant improvement over metal-jacketed rounds. Trust me, if you spend any amount of time training with steel targets at 25 yards and closer, it is inevitable you will have a piece of a jacketed round strike you. That is why eye protection is imperative.

In addition to the elimination of copper fouling, Federal Ammunition incorporated two advancements into its Syntech lineup relating to propulsion. All Syntech ammo is loaded with special clean-burning propellants, and these powders are ignited with a new lead-free primer. This new primer utilizes what Federal calls Catalyst™ technology, and it provides hot and extremely reliable ignition, burning the propellant better. This means that in addition to the absence of copper fouling, you also have a noticeable reduction in carbon fouling. The clean burning, reduced lead and safety aspects of the Federal Syntech round are really amplified when used in an indoor range setting, to which many departments, agencies and civilian gun shop ranges are confined. The advantage of Syntech is obvious and not easily dismissed.

Syntech Training Match

For a round to be embraced as a training and/or match round, it must maintain accuracy standards within accepted norms and not break the bank. The Federal Syntech Training Match succeeds here. For comparison, the 9mm Federal Premium Syntech ammo retails for about 32 cents per round and American Eagle FMJ ammo for about 29 cents per round. In .40 S&W, the difference is about 5 cents and in .45 ACP about 6 cents. None of this means anything if Syntech rounds are not comparable to other loads’ accuracy and reliability. When a shooter touches off a round, they want to hear “bang” and not worry if it landed where intended.

Each specific Syntech product has its own nuance. For example, Syntech Training Match products offer the same velocity, trajectory and point-of-impact as equivalent Federal Premium HST and Tactical duty ammunition. This makes sure your training gives the same feedback as duty ammunition. Syntech Training Match is available in 9mm 147 GR and 124 GR, .40 S&W 180 GR and .45 ACP 230 GR.

Syntech Action Pistol

Syntech Action Pistol meets the U.S. Practical Shooting Association’s (USPSA) Power Factor guidelines out of the box. Federal estimates only about 20% of action shooters use factory ammo due to Power Factor concerns. This is where the company saw an opportunity to create a round that would meet the USPSA’s Power Factor but not require shooters to reload. USPSA’s sanctioning of Syntech Action Pistol as the official ammunition of USPSA means shooters can bypass the chronograph test required at most matches because their ammo is guaranteed to make Power Factor. The Syntech Action Pistol 9mm weighs 150 grains. This is not random or just because this is what Federal had lying around. It is the end result of a lot of experimentation to find a soft-shooting load that makes Power Factor. Furthermore, the Syntech Action has meplat designed to smack steel harder and cut cleaner holes in targets.

Syntech PCC

Syntech PCC was created for the increasingly popular PCC (Pistol Carbine) competition class. Velocity and accuracy are optimized for long gun barrel lengths, with a bullet profile that provides excellent accuracy and reliable feeding in a variety of carbine platforms. Syntech PCC is offered in 9mm 130 GR.

Defense Rounds

What started as training and competition ammo has now expanded into personal defense. The defense rounds’ polymer coating is a distinctive blue to easily differentiate between training and protection rounds. The Syntech Defense projectile is constructed with a deep, hollow-point cavity, which causes the bullet to split apart into four sections upon impact. The bullet core achieves 12 to 18 inches of penetration in both bare ballistics gel and through heavy clothing with purposely created segments creating three secondary wound channels more than 6 inches deep. This is quite different from standard hollow-points that mushroom, creating a single, large wound cavity. Syntech Defense is available in 9mm 138 GR, .40 S&W 175 GR and .45 ACP 205 GR.

A Quality Product

I have been using Federal Syntech 9mm in its various forms for almost a year now for training courses, competitions and reviews involving handgun, SMG and PCC types of platforms. The total number of Syntech rounds fired measures in the thousands. While the launching platform may have changed, the Federal Synthetic has performed as advertised. Echo Valley Training Center’s Hesco Shoot House was a popular venue for putting Federal Syntech ammunition through its paces. Action is fast-paced inside a shoot house scenario where each target is engaged with multiple rapid strings of fire; ideal for heating up firearms and making sure ammunition performs in harsh environments.

Handloaders can also get the benefits of the same groundbreaking design in Syntech component bullets, as Federal sells these components separately. Bullets for reloaders are available in 9mm .355-inch, 115 GR; .40 cal., .400-inch 165 GR; and .45 cal., .451-inch 230 GR.

The validity of the Federal Syntech approach is proven by the expanding lineup of loads. It will be exciting to see how far the concept will be pushed in the coming years.

The trend towards shrinking firearms into smaller and lighter packages is full steam ahead. The recently introduced SIG SAUER MPX Copperhead is a perfect example of this. The MPX Copperhead is a derivative within their MPX 9mm SMG product line. Similar to other weapons within the SIG SAUER catalogue, the MPX Copperhead was a response to a specific customer request. The MPX Copperhead was purposely built to be the smallest possible size for carry in a bag or in a vehicle weapon. This is reflected by the 3.5-inch barrel, allowing for an overall length of 14.5 inches! Its weight is a feathery 4.5 pounds. This is not a misprint.

Some would have you believe we have arrived at the end of the submachine gun (SMG) as a viable weapon class. They point to the SMG’s steady relegation to the sidelines in terms of use since the end of WWII. The first impetus of this path occurred with the rise of the assault rifle, characterized by controllable select-fire capability with its intermediary round compared to the full-powered main battle rifles of the early 20^th century. The appearance of Personal Defense Weapons (PDWs) seemed the final death knell of the SMG.

The PDW is characterized by its compact size, much like an SMG—centered on new cartridge designs facilitating the penetration of body armor out to a couple hundred yards. The PDWs search was stimulated when NATO had images of body-armored Spetsnaz troops running amok in rear echelon areas. The FN 5.7 and HK 4.6 are two of the more prominent examples of PDW cartridge types. Times and threats have changed, breathing new life back into the SMG genre. While certainly not comparable to a rifle cartridge, a 115- to 147- grain 9mm instills more confidence than a PDW’s 23-grain .22 caliber bullet (or smaller) when having to put down an opponent in close quarters.

Recent events illustrate what a dangerous world we inhabit with terrorist attacks growing in frequency. If a hostile situation is encountered, the civilian will most likely be defending himself with a handgun. A handgun is definitely not the optimum choice, especially when compared to a rifle. A handgun is a compromise between portability and performance. A compact concealed carry handgun is an even further compromise along this continuum, i.e., not your preferred full-size high-capacity blaster. A weapon like the braced SIG MPX Copperhead, which legally speaking is a handgun, concealed in a small discreet pack could very well be considered a force multiplier compared to a prototypical handgun.

The SMG’s most prominent role, indeed its raison d’être stretching back to the WWI trenches, is as a CQB weapon. The increase in terrorism, organized crime and drug smuggling with the resultant militarization of law enforcement teams to deal with these well-armed opponents has created a new need for the SMG type of weapon. Along these same lines civilians concerned and willing to take more responsibility for their own security can find a solution to their conundrum with a weapon like the MPX Copperhead. The SIG SAUER MPX Copperhead is poised to reassert SMG potency and viability.

The initial SIG SAUER MPX model was a much-heralded introduction at the 2013 SHOT Show. SIG’s goal with the MPX was to provide an updated replacement for aging submachine guns found worldwide. The MPX class, including the Copperhead, operates via a scaled-down, short-stroke gas piston adapted for use with pistol caliber cartridges. The use of a fully closed and locked rotating bolt is another enhancement. This sets the MPX apart from previous SMG designs which operated via blowback, recoil or roller-delayed methods. The SIG short-stroke gas piston allows the SIG MPX SMG series of weapons to run all weights and brands of 9mm ammunition with no adjustments to the gas valve. MPX operating controls and basic ergonomics are similar to the ever so prevalent AR-15; an important consideration for training/orientation purposes. An AR-like ambidextrous magazine and bolt release along with a centrally located non-reciprocating charging handle will be instantly familiar to any AR user. An AR M4 flat-top upper allows for any AR-type sighting system. This AR-centric theme is reinforced by using an AR-type fire control system.

Features

The distinguishing MPX Copperhead features are the 3.5-inch barrel with integrated brake, monolithic Elite Series Cerakote finish upper receiver with an integrated stock knuckle lower and new SIG SAUER Pivoting Contour Brace (PCB), meeting customer desire for more compactness. The PCB brace easily conforms to the movement of the shooter’s arm with a patented swivel operation for adaptable placement and can be rapidly deployed via extended backward from the receiver. Some may complain of the lack of a threaded barrel on the MPX Copperhead for mounting a suppressor. When queried about this, SIG answered if suppressed fire is a desired trait then another member of the MPX family can be chosen. The MPX Copperhead’s integrated brake allows for the shortest barrel configuration possible. The Copperhead’s design intent was compact firepower … period.

No weapon, no matter what theoretical advantage is offered, is worth considering if not reliable. As with most automatics, magazines are a crucial linchpin. Reports indicate SIG SAUER worked with Lancer to develop the polymer magazines for the MPX. Lancer took advantage of their experience with AR-15 magazines to create a translucent magazine with steel reinforcing inserts at the feed lips and a magazine catch slot. The MPX magazines are designed to present the next round almost directly in line with the chamber. This enhances reliability with the full-auto MPX versions’ high cyclic rate. Another benefit of this is allowing for the use of non-FMJ profile bullets; i.e., JHPs—something important for law enforcement or personal defense considerations. One note here is that one must pay attention when purchasing MPX magazines. Make sure Gen 2 MPX magazines are used with the MPX Copperhead. Gen 1 magazines that were tested proved problematic.

The SIG SAUER MPX Copperhead’s non-discriminatory handling of several types of 9mm ammunition was a pleasant surprise. Winchester 9mm NATO loads were initially tested based on experience with older 9mm SMG designs requiring the higher-pressure NATO loads to operate reliably. The MPX Copperhead functioned flawlessly, not only with the Winchester 9mm 124-grain NATO FMJ loads, but also with SIG SAUER 365 FMJ/Elite and V-Crown JHP. Federal’s new Syntech loads were also employed. The ability to feed the JHP and other bullet profiles was a totally unexpected bonus and a credit to the MPX design and further increases its potency as a CQB weapon for LE and civilians.

Find What Works

We might as well speak about the gorilla in the room when it comes to weapons turned into pistols from designs more associated with stocked SMG or rifles. What does a pistol like SIG SAUER MPX Copperhead offer? The answer here is nebulous based on user expectations and intentions. For many, a non-traditional pistol like the MPX Copperhead, while enticing due to firepower potential, lacks much in terms of accuracy past normal handgun ranges with an added negative of weighing twice as much as a typical handgun. Another possible method could be derived from how certain European special operation units run their weapons. The end of the weapon is floated on the cheek providing three points of contact for more stability and thus accuracy. While not optimum and not nearly as effective as a true shouldered stock, the alternate methods proved superior to merely attempting to hold the MPX Copperhead via traditional pistol method, especially when the goal is rapid fire rounds downrange with a semblance of accuracy. Attentive training will pay dividends in finding what works best for individual users.

Evaluation

The SIG SAUER MPX Copperhead was tested at Echo Valley Training Center. A SIG SAUER ROMEO 4 red dot was mounted. Iron sights are not provided with the MPX Copperhead. Several 30-round magazines were fired rapidly downrange. The MPX Copperhead has an ambidextrous charging handle that is very similar in appearance and function as the AR-15. It was determined that manual operation worked best by placing fingers on both sides of the charging handle so as to pull back evenly. The ambidextrous safety and magazine levers were found in familiar places to anyone who has operated an AR. The MPX Copperhead proved durable during testing at EVTC with nearly 700 rounds fired over multiple range visits. Most importantly the SIG SAUER MPX Copperhead demonstrated reliability. EVTC’s Hesco Shoot House was a popular venue for testing.

Magazine changes with the MPX Copperhead proved a smooth affair indicative of AR-like ergonomics. The closed-bolt MPX does have a bolt hold-open device which is different than most SMG designs, aiding in swifter reloading. The balance of the MPX Copperhead combined with firing 9mm in a 4.5-pound weapon minimizes any recoil or muzzle climb. This is especially important in the MPX Copperhead’s select-fire brethren with a cyclic rate over 1,000 rounds per minute (rpm). The piston-operated rotating bolt MPX contributes here as well. Bolt weight is minimal compared to more traditional SMG blowback methods featuring a hefty chunk of metal for operation. Strings of multiple rounds sent downrange smacked steel with no problem due to minimal muzzle climb. The diminutive nature of the MPX Copperhead can cause nervousness in users based on hand placement on the pint-size weapon. You definitely do not want to take a high thumb forward grip.

When everything is stripped away in terms of its design innovations, aesthetics and ergonomics, at its core the SIG SAUER MPX Copperhead is a compact 9mm SMG intended to put rounds on target in a hostile environment. The MPX Copperhead is lighter and handles better than its full-powered assault rifle brethren. While not as prevalent of late, there is an economic advantage in terms of the 9mm amount that can be purchased versus a rifle cartridge. These economics can be taken advantage of with more training; not to mention the ability to access indoor ranges or shoot houses with a pistol caliber weapon such as the MPX Copperhead. The training regimen is further enhanced by using 9mm with steel plate targets without having to resort to specialty frangible rifle loads. The Federal Syntech loads are especially suited for engaging steel at close range with minimal chance of bullet spalling/splashback. Also, less experienced shooters will find the lower recoil pulse and muzzle blast of a pistol caliber easier to manage, which often times will translate into better accuracy potential.

The SIG SAUER MPX Copperhead represents the revival of the SMG. The MPX Copperhead will force a reevaluation of SMG use for law enforcement or direct-action military units. Most engagements are successful within a 100-yard range, especially in LE, MOUT or civilian settings with handling and reliability playing more of a factor in quick, reactive engagements versus the specific caliber used. Along these same lines a civilian concerned with home defense will find the MPX Copperhead hard to resist with its high capacity and great handling. The muzzle blast differential between a 9mm versus an obnoxious rifle muzzle signature is further accentuated in confined spaces—such as inside a home. Will a rifle cartridge hit with more authority than a 9mm? Yes, of course, but mission specifics may dictate when the SIG SAUER MPX Copperhead is a more practical choice of weaponry.

It is no secret that Eugene Stoner’s AR platform is the bestselling rifle in the U.S. with numerous manufacturers jumping on the bandwagon in recent years by offering their versions. In general terms, ARs come in two patterns—AR-15 and AR-10; the AR-15 is most associated with 5.56mm/.223Rem and AR-10 with 7.62NATO/.308Win. Many would characterize the AR-10 as an AR-15 on steroids, with its larger size, larger caliber and heavier weight. It is assumed that the AR-10 will be of greater proportions due to its need to accommodate the larger .308Win cartridge—challenging this assumption is the purpose of this article.

The AR-10 actually pre-dates the AR-15. Eugene Stoner first introduced the AR-10 in 1956 in a hasty effort to compete against the M14 in the U.S. Army weapon trials. Stoner designed the AR-10 around direct impingement gas operation combined with innovative straight-line barrel/stock design using composite and forged alloy parts. In 1957, the basic AR-10 design was scaled down and substantially modified by Armalite to accommodate the .223 Remington cartridge and was given the designation AR-15 with the rest being history.

Without a doubt the POF-USA Revolution AR rifle will change users’ thoughts on how a .308Win AR rifle can be configured. While we will focus specifically on the POF-USA Revolution DI for this article, POF offers numerous other models—direct impingement and piston-driven—as well as multiple caliber chamberings. From the beginning, POF-USA charted its own path in enhancing the AR platform with innovative features.

So what separates the POF Revolution DI from other .308Win AR-10s? Often the AR-10 is associated with an unwieldy profile weighing substantially over 9 pounds. POF-USA has made a conscience effort with the Revolution to harness .308Win power within an AR-15 frame offering the user superior terminal ballistics while maintaining svelte handling. The Revolution DI is not merely a reduced scale AR-10 rifle. The Revolution DI uses the same length bolt carrier assembly, handguard, barrel extension, charging handle, upper/lower receiver, etc., as an AR-15 while still offering .308Win battle rifle punch.

New Features and Improvements

POF features that have created a cult-like following are present on the Revolution DI along with some new ones: fully ambidextrous billet receivers, a high phosphate, nickel-coated bolt carrier group, 5-position adjustable gas piston and a single-stage match grade trigger. The POF Revolution DI measures 34 inches (Mission First Tactical stock collapsed) and weighs 6.8 pounds. The Revolution rifle tested for this article features a Black finish, with Burnt Bronze also being an option. It features a 16.5-inch, 1:10 twist fluted chrome alloy barrel that is nitride heat-treated for full corrosion resistance. A POF-designed triple port muzzle brake aids in recoil management and flash suppression. Quality magazines are a linchpin for a reliably functioning semiautomatic or select-fire weapon, and in the Revolution DI’s case, Magpul PMAG® 20 LR/SR 7.62 magazines are used. This is a huge plus in my opinion. Magpul’s PMAG LR/SR magazine is quickly becoming the standard .308Win AR magazine.

POF-USA will never be accused of being stagnant or resting on the designs of others. Multiple examples of this exist, with Revolution DI beyond the already impressive weight/frame dimensions. POF-USA’s patented E2 dual-extraction method consists of four small channels cut into the walls of the chamber allowing a small amount of gas pressure to push against the neck of the spent case. This pressure assists in extraction by breaking the seal between the chamber and case as well as pushing the spent case to the rear as the extractor is pulling to the rear. This removes a tremendous amount of work that would otherwise be left up to the extractor.

The POF-patented, oversized, 3-inch-long heat sink barrel nut is another significant improvement. The POF barrel nut is much more efficient at heat dissipation than the standard AR barrel arrangement. Additional benefits are that the operating rod is better supported to bolt carrier, which strengthens the upper receiver, especially when accessories or vertical fore grip are mounted to the forend.

The POF-USA bolt carrier is a one-piece, high phosphate, nickel-coated affair, with the mechanical key built into the body and positioned behind the cam pin. This patented design helps reduce carrier tilt. The POF bolt carrier group features a chrome-plated bolt, extractor and firing pin. The finishes are corrosion-resistant and introduce lubricious characteristics to the action. Innovation does not stop here. No detail is too small if the operating efficiency increases. The patented roller cam pin reduces friction and drag in the action. Standard AR cam pins feature a square steel head that literally grinds and carves away at the inside of the receiver. POF-USA’s NP3-coated roller head actually rolls inside the channel of the upper, thus eliminating friction and prolonging the life of the upper.

POF labels their Modular Railed Receiver (MRR) as their “crown jewel for precision and extreme rigidity,” which are so important for reliable accuracy. This is a two-piece upper assembly with a free-floating monolithic handguard that slides on and interfaces directly to the upper assembly thanks to POF’s reinforced “backbone” flattop upper receiver. The suspended handguard keeps your grip and accessories from interfacing with the barrel, providing six points of attachment and keeping the rail from experiencing any movement under stress. The forend is fully M-Lok-compatibile with the front top and bottom section of the rail for sights and a bipod/other accessories. Four QD sling-mount slots round out the forend.

The POF-USA Revolution DI rifle utilizes an adjustable direct impingement operating system. The Dictator adjustable gas block lets you tune your rifle to the exact operating speed it should be. When your rifle runs too slow, or too fast, it’s more prone to failures. With the Dictator’s nine adjustable settings and straight gas tube, using different ammunition and suppressors are no problem. The POF goal here is more reliability and a smoother shooting rifle.

The final touches that set up the POF Revolution DI for success are the triple port muzzle brake and POF drop-in trigger. Each facilitates better user interface with the rifle. The POF muzzle device is nitride heat-treated and designed to control gas dispersion and to reduce muzzle rise, allowing the shooter to have faster follow-up shots and dampen felt recoil. The blunt strike prongs on the end of the brake are a nice touch and help set both aesthetic and martial tones. The trigger is a single-stage, non-adjustable, 4.5-pound pull weight drop-in trigger. KNS Precision, Inc.’s anti-walk trigger pins are used to secure the trigger into the lower receiver.

Putting the Revolution DI to the Test

This author’s guiding thought for the POF Revolution DI evaluation was to treat the DI similarly to an AR-15 in terms of setting up scenarios that would assess its handling and ability to send multiple rounds downrange quickly and effectively. Working in and around vehicles provides this type of realistic feedback. In an effort to maximize the POF Revolution DI’s potential in terms of accuracy and flexibility, a Trijicon AccuPower 1-8x28mm 34mm tube optic was mounted on the railed upper receiver. The 1-8×28 power range offered by the AccuPower solves any conundrum posed by other, more limited optic magnification options. I have come to rely upon the Trijicon 1-8×28 for many of my recent rifle reviews thanks to its magnification range that allows for close-range training evolutions with its 1x illuminated reticle as well as its ability to engage distant targets with greater precision.

Initial accuracy testing involved Champion pedestal rest and bags combined with premium .308Win ammunition in the form of Federal 168-grain Match, SIG SAUER 168-grain Match, Winchester 168-grain Match, Black Hills 168-grain Match and Hornady 168-grain TAP. Winchester 147-grain FMJ was used for high-round count drills. The Revolution DI produced MOA groups with the Federal 168-grain and only slightly larger ones with the SIG SAUER, Hornady and Black Hills.

Concerns related to over-penetration using a .308Win chambered rifle such as Revolution DI could be addressed with ammunition selection. For example, the Winchester PDX1 Defender loads for the .308Win, featuring the Split Core Technology 120gr bullet, comes to mind. The Winchester Split Core .308 has a forward section where the lead core is not bonded to the jacket. This is done to enhance rapid and massive expansion. The lower portion of the core is welded to the jacket to hold the bullet together even though the nose section opens violently upon impact, dumping energy into the target and making sure the round does not over-penetrate a soft target such as a human adversary. This Winchester offering could prove to be a favorite law enforcement, or even civilian personal defense, load for any department wanting the ballistic advantage of the 7.62x51mm/.308Win while minimizing concerns of over-penetration. Ballistic gel demonstrations witnessed in person and also via the internet indicate the Winchester .308 Split Core comes to rest after 12-14 inches of travel in the gel.

While the Revolution DI was more than capable of connecting with various steel targets arrayed along Echo Valley Training Center’s (EVTC) stepped berm out to 330 yards, working with it inside EVTC’s 360-range and Hesco Shoot House would be the true measure of whether the Revolution DI delivered on its promise as a different sort of .308Win AR. Drills started out with working around simulated cover while engaging designated targets in and around EVTC range vehicles to allow evaluators to get a “feel.” Scenarios were then set up to force magazine changes as well as moving to various firing points. Eventually, the POF Revolution DI was moved to within vehicle confines where evaluators fired on targets from the range vehicles as well, quickly exiting the car and maintaining rounds sent downrange. Steel targets are struck with awesome authority when 150+ grains smack into them, especially from close range. It is easy to tell the difference between 5.56mm and .308Win impacts at any distance.

Versatile

For a rifle to be considered truly considered versatile, it must be able to satisfy multiple roles with equal aplomb. A definite candidate for this title is the POF-USA Revolution DI chambered in .308Win. .308Win potency in terms of ballistics and terminal effect makes it a favorite among our troops and law enforcement personnel in more rural environments. A look at the resurrection of the M14 and most AR manufacturers maintaining an AR-10 in their model lineup support this observation.

The added weight of most AR-10 platforms compared to the smaller AR-15 negates inherent AR qualities of handling in many users’ minds. The combining of the great handling AR-15 platform with the increased power represented in the .308Win cartridge is the key to the Revolution DI’s allure. This is speaking in terms of the Revolution DI’s lethality and effective range, while still allowing for multiple rounds sent quickly downrange if needed in a close-range melee. In training courses involving LE, military and private security contractors, the mantra of “one mag, one kill” is often repeated in relation to the M16/AR-15. While the 5.56mm round is often chided in terms of lethality, the .308Win does not suffer from this reputation.

The Verdict

Years of experience and dozens of training courses have formed strong opinions as to what constitutes an effective fighting rifle. What I mean by this is a return to AR basics such as great handling rifles with potent firepower. The POF Revolution DI’s ability to maintain a functional weight of 6.8 pounds while featuring .308Win firepower is hard to deny as a potential candidate for “all-around” performer.

The POF-USA Revolution DI proved reliable throughout this evaluation with approximately 550 rounds fired; many of them rapidly, without cleaning the rifle during multiple range visits. The Revolution is superior to other AR-10 rifles I have tested in terms of handling and maneuvering. The Revolution DI covers the gamut of likely situations encountered by law enforcement or security conscience civilians with equal confidence. This is a reflection of POF-USA Revolution DI design and use of the .308Win chambering. POF-USA’s thought process was to create a lightweight, simple-to-operate AR rifle similar to Eugene Stoner’s original concept while accessing the .308Win cartridge’s power. POF’s experience and industry leading developmental commitment is shown with the Revolution DI.

Many have become increasingly interested with the ability to “see” at night albeit via traditional image intensifying night vision or thermal technology for various reasons … tactical, hunting, surveillance, general principle “because you can,” and so on. Each system has its advantages. Most of us realize from the first Gulf War in 1990-1991 and subsequent involvements in Iraq and Afghanistan that night vision has revolutionized the modern battlefield and is a crucial advantage exploited by our armed forces over less well-equipped opponents. As often happens with advanced military technology, it finally trickles its way down to LE and civilian users. Our focus will be on the thermal technology as represented by the Trijicon REAP-IR (IRMS 60 model).

Trijicon has entered the optics market in force over the last several years with several innovative designs and new takes on established concepts. Trijicon has evolved into a recognized industry leader in the development and manufacturing of all types of optics such as red dots, magnified optics, handgun iron sights and recently thermal. Trijicon definitely has “skin” in the optics game with numerous models in its product line-up.

Trijicon acquired prominent military contractor IR Defense—including its products, R&D and manufacturing plant—as the basis for a new Electro-Optics Division. As is the case with most of its products, Trijicon thermal optics are manufactured in the US. Currently, multiple product lines are offered in the form of rifle scopes (with several models), monocular and clip-on thermal versions. Trijicon also has a licensing agreement with BAE Systems for their OASYS thermal imaging and aiming technology. With this technology license, Trijicon positioned itself well to provide compact,

high-performance thermal imaging and aiming monoculars, weapon sights and binoculars.

The technical aspects of the Trijicon REAP IR must be discussed to ensure full appreciation. These will be applied in the hunting arena as well as in trials in the LE realm as part of both patrol and training scenarios. I have heard that thermals are not optics per se. Yes, the similarity to traditional rifle scope form is hard to miss. A better way to think of a thermal such as the Trijicon REAP-IR is as a digital camera feeding off of infrared/heat waves with a signal processor creating images for our recognition. The REAP-IR has a sensor resolution of 640×480 pixels, which is currently leading edge for thermal scopes. It has a sensor pitch of 12 microns which allows for sharper images versus the more prevalent 17-micron pitch models found on the market. 12-micron capability allows for increased magnification potential as well. The scope also has a frame rate of 60 Hz, meaning the thermal core refreshes the image you see 60 times a second; all of this is crucial for successful tracking/engagement/observation of moving targets.

The Trijicon REAP-IR features multiple reticle save locations. This capability allows a user to transfer the REAP-IR between different weapon platforms by associating certain reticle locations with a specific weapon that has been sighted in accordingly. The REAP-IR also has 5 different reticle patterns to choose from to suit users’ needs.

A Stadiametric Range Finder allows for fast and accurate ranging of targets. Users can quickly determine the distances to target by setting ranging units and target size. The ranging “reticle” is then adjusted to the target being viewed, and the distance is displayed on the Range Read-Out Display.

Trijicon has equipped the REAP-IR with an Edge Detect Mode. This feature was pioneered in military thermals after getting feedback from operators. The two CR123 Lithium batteries provide approximately 4 hours of run time. Edge Detect helps to limit user eye fatigue and allow the user to stay behind the thermal optic longer. This is done by reducing the brightness of the overall display to reduce night blindness when coming off the scope, while still outlining objects producing a heat signature to better grab the user’s attention. Less light emitting from the back of the thermal also helps to prevent inadvertently revealing a shooter’s position.

Other enhancing REAP-IR features are White Hot/Black Hot Polarity control and Digital Focus Control (DFC) ensuring zero is maintained during magnification increases of 4.5x optical and 8x digital. DFC will auto-sharpen images to enhance clarity and detail. The Polarity control offers users three levels, each of white hot/black hot for adaptation to specific situations. Trijicon thermal scopes are built to MIL-STD-810G standards translating into being capable of withstanding temperature extremes, rain, humidity, sand, dust, vibrations and shock standards based on specific testing.

All features such as sighting-in, Polarity adjustments, magnification adjustments, reticle choice, etc., are chosen via thumbstick toggle control on the right side of the REAP-IR. Users familiar with higher end digital camera interface methods will find REAP-IR controls familiar. The screens that appear and are toggled through are very similar to modern DSLR cameras. Initial reference to the well-prepared user manual will guide you to the screen required. After a few tries, the grouping of features is easily figured out. For example, the “Easy Zero Method” makes sighting-in easier than for a traditional optic. Once the correct screen is found, follow the onscreen prompts. When in effect, fire a round from a stable position. Inspect where the round impacted and toggle adjustments into the optic via MOA readout to then place reticle where the round landed versus the aiming point. Firing another round or two for confirmation is always recommended.

The REAP-IR was mounted on a SIG SAUER 716G2 DMR .308Win. A SIG SAUER 7.62 suppressor rounded out the potent package. The author’s thought was to limit the need for ear pros once taken afield. One nuance with the sight-in procedure was placing duct tape on the target to provide an aiming point when viewing through the REAP-IR thermal—on paper target only provided no real center reference. The “Easy Sight” mode got the REAP-IR zeroed within five rounds. The theoretical eye relief is 27mm with the REAP-IR calculated to see the entire eyepiece field of view. Functional eye relief is longer than that since you do not really need to see the entire eyepiece FOV to see the screen well. I bring this up as an important nuance, especially with weapons chambered in cartridges in the .30 caliber or up power range.

Once the platform for the Trijicon REAP-IR was chosen, sighted-in field use got seriously underway. Immediately, several night forays were set up in pursuit of predators and general usage to get a sense of what the Trijicon REAP-IR (IRMS 60) offers. The compact 7.5-inch long, 32-ounce REAP-IR delivered surprisingly detailed imaging performance out to 300 yards plus. There was no issue identifying deer, coyotes, raccoons and foxes. The polarity contrast of heat actually made detection easier in certain areas than if merely using binoculars during the day. The amount of heat signature of vegetation was surprising in thicker/denser areas. However, the ability to adjust settings with the REAP-IR maintained the ability to observe effectively. The preferred method was to keep the REAP-IR at a low magnification setting for observation purposes and then increase magnification as needed for shot placement.

One huge advantage of a thermal is its ability to be used during the day. Image intensifying night vision optics are not so flexible. The Trijicon REAP-IR has a temperature sensitivity listed as less than 50mK which converts to .09 degree Fahrenheit! This sensitivity allows for the REAP-IR to be used in a tracking mode either for tracks or blood trails, even during the day. The DLOC mounting bracket with the REAP-IR allows for it to be easily removed from the rifle and used as a hand-held unit with reinstall maintaining zero.

Besides the hands-on field hunting experience with the Trijicon REAP-IR, various Federal and local contacts were utilized to gain their insights into the best use practices of thermal optics related to law enforcement. Several “ride alongs” proved educational. There was no doubt the Trijicon REAP-IR was a performance enhancement over white light. Thermal optics allows officers the ability to see their surroundings in a brand new way; pun intended. The technological advantage is similar to what our military experiences. The night can no longer shield suspects. Officers using thermal optics have a range of abilities not available with flashlights or even image intensifying night vision optics.

Weapon-mounted sights are not necessarily the thermal optics forte in the LE realm due to the uncompromising need to positively identify a target before engaging. What the REAP-IR offers is unsurpassed surveillance capability and huge assistance in fugitive searches both day and night in urban or rural settings. Dark or camouflaged clothing worn by a suspect can make it very difficult for officers to use light or night vision technology to distinguish him from his surroundings. With a thermal imager, officers have the ability to see the suspect’s body heat, which makes it very difficult for the suspect to conceal his position, whether he is hiding inside of a structure or outdoors. Imagine rolling up to a situation and being able to quickly and discretely assess potential problems in terms of individuals hiding or even animals that may be encountered. This scenario can be expanded to include a suspect on the run and/or cornered.

One large open space approximately 800 yards long showed the Trijicon REAP-IR’s potential with no issues detecting heat signatures at extended ranges for animals or human passersby. Larger objects such as vehicles show up even further out. For a law enforcement officer or security minded civilian, this could translate into detecting objects at a distance; then, closing the gap and being able to determine what the object is …warm engine block, a dog—or a fleeing suspect.

Another capability tailor-made for thermal optics is search and rescue. The Trijicon REAP-IR in a hand-held capacity can help officers search large areas in short order. Officers may be able to search hundreds of yards in any direction quickly thanks to people’s inability to hide body heat. The Trijicon REAP-IR eases search efforts in large fields, parks, near roadways and wooded areas. Searches near bodies of water also offer opportunities to use a thermal imager. As long as the victim is not completely submerged, body heat should be detected by the thermal imager. You can scan a large area in seconds and detect life-based emitting heat sources.

The Trijicon REAP-IR is an awesome piece of equipment. Some will point at the price tag and snort; totally understandable. However, cutting edge, top tier gear that allows you to experience another sense beyond our God-given five will never be had on the cheap. The image clarity and detail are impressive. With the Trijicon REAP-IR, nothing can hide day or night.

Accuracy International (AI) has been a well known entity in the precision rifle marketplace since the mid 1980s. AI’s innovations have shaped and influenced the precision bolt action genre of weapons. Much of this stems from AI’s non-typical background for a firearms firm. AI’s founders were competitive marksmen, one of them an Olympic gold medalist and World Champion. AI rifles stemming from this target background was unique in the 1980s when the company was founded. Up to that point sniper rifles were converted hunting or existing service weapons. Accuracy International started with a clean sheet of paper with precision as the guide line. This is something we take for granted today, but was revolutionary when the AI platform arrived on the scene in the mid 1980s.

Accuracy International’s emergence stemmed from the British military’s call for an updated sniper rifle after the 1982 Falklands War. The existing British L42A1 had only been in service since 1970. However, the L42A1’s bolt action design stretched back to the turn of the 19th-20th Centuries. The Falklands War fully illustrated its weaknesses in terms of the wood stock warping compromising accuracy and other issues compromising performance. Accuracy International was the surprise newcomer winner of the search for the L42A1’s replacement. Their rifle was designated the L96 and entered service in 1985.

Nightforce ATACR 5-25x optic attached to the AX50. The red circles are blow out plugs intended to protect the shooter in from case failure.

Rather than a traditional wooden wood or fiberglass stock, the AI L96 was based on an aluminum chassis. All other components, including the receiver, were bolted directly to this chassis. The Accuracy International receiver is bolted with 4 screws and permanently bonded with epoxy material to the aluminum chassis. The heavy walled, flat bottomed, flat sided receiver is machined in-house by AI from a solid piece of forged carbon steel. Two polymer panels with either a thumbhole or pistol grip configuration were also attached to the chassis.

The Accuracy International product lineup has evolved over time. This stems from user feedback as well as responding to improvements in manufacturing materials and methods. It is not sound practice for any business to resist change or better methods of doing something; this smacks of institutional stagnation. Accuracy International does not suffer from this as evident with the emergence of their AX and AT series of rifles in recent years.

The AI rifle evaluated for this article is the AX50 chambered in .50BMG (12.7x99mm). As befitting the cartridge it is intended to harness, the AX50 is a scaled up bolt action dwarfing typical rifles. The Accuracy International AX50 measures 54 inches long and weighs 27 pounds empty. A folding stock reduces length to 44 inches for transport. The 27 inch 1:15 twist barrel has a triple chamber muzzle brake attached to mitigate recoil. The match barrel is free floated and secured to the action via large 39MM diameter threads. The AX50 is fed from a five (5) round detachable magazine. A night vision mounting rail is available. The rail is fitted to the slotted forend that surrounds the barrel, allowing for a forward mounted night vision device to be placed in front of the day optic.

AX50 six lug bolt shown next to an AR15 bolt group for comparison’s sake to illustrate size.

The AX50’s 30MM diameter bolt has six locking lugs and AI’s field proven one-piece extractor. The six lug design allows for a short 60 degree bolt handle lift to unlock the action. The AX50’s high grade steel action is flat bottomed with integral Picatinny rail. As per the original AI L96 rifle, the AX50’s action is bolted to the aluminum chassis along its entire length with being fitted with a full width recoil lug to prevent movement ensuring zero is maintained in all conditions. The AX50’s bolt action is comprised of a one-piece bolt body and receiver constructed from a solid bar of steel. The six-lug action is the heart of the rifle. The lugs are arranged in dual three lug sets around the bolt’s body giving the AX50 extra rigidity and strength for greater precision. The oversize bolt handle and smooth passage in the raceway allows for minimal disturbance when the rifle’s bolt is worked allowing for fast follow-up shots when engaging multiple targets; quite a feat considering the length and girth of the .50BMG round. In the AX50, two soft aluminum pressure release ports/plugs, colored bright red, are provided to minimize blowback danger in the event of cartridge failure. With the forces associated with the .50BMG, this safety measure is be appreciated and not to be taken lightly. The pressure release plugs are replaceable so the rifle can often be repaired and not rendered a total loss in case a cartridge failure is experienced. The AX50 has an adjustable two stage trigger with a large sear engagement before the first stage is taken up to minimize the risk of accidental discharge. Trigger pull can be set between 3.3 to 4.4 pounds.

The AX50 stock features an adjustable comb for proper eye alignment and cheek weld. Length of pull is adjusted via removal buttplates per individual shooter needs. The AI stock is rock solid with design characteristics making it conducive to long range shooting from the prone position using sand bags or bipod. The forend handles bipods or sandbags with equal aplomb. The AX50’s stock contributes to the ruggedness of the rifle ensuring that a key element of a precision rifle is met; accuracy to be constant and repeatable no matter the conditions.

The Accuracy International AX50 stems from an earlier AI rifle chambered in .50BMG, the AW50, which was introduced in the late 1990s. The AX50 is a result of requests from military end users for a more accurate anti-material weapon. The operative wording here is the emphasis on increased accuracy. The .50BMG’s power is legendary since it was created by John Browning. Anecdotal history has Browning creating the .50BMG by scaling up the 30.06 service round at the behest of General Pershing. The purpose of the .50BMG was to serve in both an anti-aircraft and anti-vehicle role with the advent of the first tanks and armored cars that began roaming the battlefield at the end of WW I. Browning’s .50BMG, typified by its chambering in the M2 “Ma Deuce”, had always been thought of as a either a crew served weapon or something better fitted to a vehicle or similar platform in order to tame its power since its introduction. While there were early attempts to create a shoulder fired .50BMG rifle, this genre has come into its own since the mid 1980s and especially flourished over the last few years with several examples of production rifles being available. World events in the 1990’s, Desert Storm, Balkans et al, transpired to give a major impetuous towards acknowledging the increased role possible with shoulder fired .50BMG rifles.

AX50 ideal platform for long interdiction of personnel or material.

While transportable by an individual, the Accuracy International AX50’s size makes it more of a fixed position platform; perfect in an over watch role, especially with its extended effective range and power. One role it has been pressed into is more of a close range weapon found at checkpoints and gated entrances to bases/facilities. Developments in .50BMG ammunition are keeping pace with the rifle component of the platform. This serves to wring even more range and lethality from the AX50. Nothing will shut down an engine block faster than an incendiary/HE Raufoss Mk211 .50BMG round if a driver is not complying with approach procedures. The big AX50’s aesthetics instills a certain sense of purpose. The purpose is allowing for one rifleman to dominate his space on the battlefield against a myriad of targets not possible by any other centerfire cartridge weapon. The AX50 is a weapon with unsurpassed power and effective range for a shoulder fired weapons. Accuracy International’s manufacturing quality and attention to detail provides an accurate, rugged, and reliable weapon that wrings the utmost performance out of the .50 BMG capabilities with the AX50.

The AX50 brings together individual high quality components into one 27 pound package. Along these same lines a Nightforce ATACR 5-25x56MM (34MM tube) was mounted on the AX50 via Accuracy International base/ring unit. Nightforce is a noted high end optic manufacturer with numerous products in use with elite military and police forces around the world. As with any purchase involving gaining a tactical advantage, it is all about perceived needs versus cost. The Nightforce ATACR features multi-coated ED glass. Based on research for this article, ED (Extra Low Dispersion Glass) glass prevents or lessens chromatic aberration because it concentrates and directs the wavelengths of light more effectively. Generally speaking, the better the aberrations are controlled the cleaner and brighter the image will appear. This is especially important at long range high magnification observation. ED glass is usually reserved for premium optics due to the cost associated with it. Other notable Nightforce characteristics of the Nightforce ATACR optic are a second focal plane reticle, ZeroStop elevation adjustment, .25 MOA or .1 Mil adjustments, Hi-Speed adjustment with windage adjustment capped, separate parallax adjustment with distance markings, digital reticle illumination, enhanced engraving, integrated power throw lever, and XtremeSpeed diopter adjustment. Many of these items are proprietary Nightforce features.

With good ammunition, not delinked bulk FMJ, sub-MOA accuracy is more than obtainable with the AX50. Hornaday .50BMG 750 grain AMAX Match ammunition was used primarily with the AX50. Delinked and FMJ .50BMG was also accessed for initial function testing and zeroing of the Nightforce ATACR optic. Remember the military mainly uses the .50 BMG rifle, whatever specific model it may be, as an anti-material weapon. Yes, rounds on enemy personnel have happened, especially in current theaters of operation in Iraq and Afghanistan, but this is not the primary mission role of the big rifles. The AX50 delivers far better accuracy than merely “minute of engine block” at extended distances with “minute of man” possible at mind blowing distances. The AX50 exceeds previous expectation in terms of accuracy form a shoulder fired .50BMG rifle. AI is not at liberty to name specific clients that deploy the AX50; however, many AX50’s have been sold to NATO forces and are in service around the globe currently.

AX50 is fed from a five round detachable magazine.

The AX50 demonstrated 1 MOA groups at 300 yards and 500 yards at Echo Valley Training Center. Large rounds such as the .50 BMG rounds often exhibit the phenomena of going to “sleep” after traveling some distance down range. For example, accuracy levels at 100 yards are often improved upon at 300 yards or further downrange. For example, a 100 yard group measuring an overall dimension of 2 inches is often followed by a 300 yard group measuring less than 3 inches. One would extrapolate that the 2 inch group at 100 yards to generate a 6 inches group at 300 yards. This phenomenon was not evident during evaluation with the AX50 either due to the ammunition used or the rifle itself. 100 yard groups were in the sub-1 inch range for three rounds with the size of the .50BMG producing only a jagged hole on the target.

AI does not advertise specific accuracy standards for the AX50 due to ammunition being such an important part of the equation. However, AX50 rifles competed headed to head with full blown custom rifles at .50Cal National Championships last year. Remember the AX50 is an off the shelf military grade sniper system, not a custom match rifle, yet it competed at this level more than holding its own. Interestingly, Hornady Ammunition was used in this format as well due to the obvious emphasis on accuracy at the match.

Recoil was surprisingly manageable from the bolt action AX50. While muzzle blast was impressive as expected, the shoulder and face was spared from discomfort. This is a compliment to the AX50’s ergonomics, muzzle brake, and overall design. Firing from supported field positions is not an issue with the AX50. The effective management of recoil translates into a user being more comfortable settling in behind the big AX50 and sending accurate rounds downrange. The Accuracy International AX50 takes a back seat to no rifle in terms of downrange interdiction power and repeatable accuracy.

Muzzle blast is as expected with the AX50, however recoil was not intolerable with even smaller framed shooters not intimidated.

Full stable of 10MMs with the G20, G29, G40 MOS

GLOCK has made noteworthy additions to their product line at the last two SHOT Shows. The GLOCK 4040 (G) MOS 10mm is an excellent example of this. In effect, the G40 MOS is a long slide 10mm Auto with 6 inch barrel combined with means of mounting a variety of red dot optics on its slide. The G40 appearance coincides with a recent up surge in handguns being chambered in 10mm Auto. Only Freud could provide analysis of why so many are deciding to explore the 10mm Auto; better late to the party than not showing at all considering the 10mm’s up and down history. GLOCK has been a 10mm standard bearer since the early 1990’s with introduction of the G20 and G29; each of which has been in constant production since. The introduction of the G40 MOS further shows GLOCK’s support of the 10mm Auto.

In firearm circles Jeff Cooper is given the most credit for the early development of the 10mm Auto. Yes, other .40 caliber pistol wildcats had been in existence. However, the 10mm Auto is the one that achieved the most commercial success. The 10mm Auto was designed to be a rimless semi automatic pistol cartridge with magnum power associated with the .41 Magnum. The ill fated Bren Ten was chambered in 10mm Auto. Fortunately, other manufacturers such as Colt and GLOCK picked up the 10mm Auto mantle keeping it viable. The brief FBI flirtation with the 10mm Auto also raised its profile within the shooting community. The 10mm Auto story must be finished by stating that the .40 S&W eventually emerged from and succeeded the 10mm Auto becoming a pre-eminent personal defense and law enforcement cartridge. In short, no pun intended, the .40 S&W is a reduced length and powered 10mm Auto. The .40 S&W case is 3mm shorter than the 10mm Auto’s 25mm case length. All of this came about as a result of the recoil of the full powered 10mm Auto causing consternation among certain law enforcement personnel and trainers.

G40 MOS.

Many detractors would have you believe that GLOCK has grown complacent by not introducing any “new” designs that depart significantly from the template laid by G17’s arrival in 1982. This is not correct considering Fourth Generation of refinement combined with multitude of calibers and frame sizes offered. The 10mm G40 MOS a perfect example of this. Yes, GLOCK is reacting to current market trends showing a propensity for using miniature red dot sights on handguns; still does not detract from fact of making such an option available. The stout GLOCK platform has proven an ideal companion to the 10mm Auto chambering from the start.

The 2010 SHOT Show was the “official” presentation of the Fourth Generation GLOCK. The 4th Generation GLOCK reflects a combination of both ergonomic and internal changes. Many will point to GLOCK finally acceding to market demand by offering interchangeable backstraps of different sizes with the 4th Generation introduction. It is suspected the increasing amount of competitors offering the ability to change grip sizes was making too many inroads into both the law enforcement and civilian markets. Grip sizes are small, medium, and large frame. Grips are changed via removing a single pin. The Gen 4 comes with the small grip frame molded the frame with the medium and large grips fitting over the frame as a user sees fit. Along these same lines 4th Generation GLOCKs receive a modified rough texture frame and grip texturing. Basic grip size is smaller with the 4th Generation introductions with the GLOCK backstrap “hump” lessoned along the lines of the previously introduced Short Frame (SF) 3rd Generation GLOCKs. This aids shooters with smaller hands by reducing the circumference of the grip frame. The medium grip size of the 4th Generation GLOCK can be likened to the grip found on 3rd Generation GLOCKs. The magazine catch on the 4th Gen GLOCK is enlarged and reversible requiring no additional parts to do so. 4th Generation GLOCKs come with three (3) magazines configured with the cutout catches on either side of the magazine body. All previous GLOCK magazines will work with the 4th Generation GLOCK as long as the magazine catch is configured on the frames left side.

The G20 10mm is the “standard” sized GLOCK resembling a muscled up G17 with 8 inch length and 1.27 inch width (G17 is 1.18 inches wide). The G20’s hexagonal rifled barrel (more on this later) measures 4.6 inches. The Gen 4 G20 variant arrives with three (3) 15 round magazines. The G29 10mm is the more compact variant measuring 6.88 inches in length thanks to 3.7 inch barrel. Width is 1.27 inches. The G29 features 10 round magazines, though the 15 round G20 magazines will fit as well. The G29’s size offers compact size, roughly analogous to 1911 Commander, with superior capacity and firepower. The last tale of the tape will focus on the new G40 MOS. It is a true “long slide” reminding one of 17L dimensions. A length of 9.5 inches provides extended sight radius. G40 MOS width is 1.27 inches. The 6.02 inch barrel gets the most out of the 10mm Auto in terms of velocity.

Various sight systems were used in conjunction with the different GLOCK handguns.

10mm Auto ammunition from Federal, Buffalo Bore and Hornady was accessed for use in the 10mm GLOCK handguns. Buffalo Bore is a prime source of true 10mm Auto ammunition offering several bullet types ranging from hard cast, JHC, to FMJ-FN. Buffalo Bore hard cast bullets are not verboten with the GLOCK hexagonal rifling. This goes against typical warnings related to lead bullets. This is because of the differences between soft lead “cowboy” bullets and hard cast bullets. True hard cast bullets (as opposed to lead swaged bullets) that are properly lubed will not lead foul hexagonal barrels any more than any other type of rifled barrel. Hard cast bullets are not “lead” bullets as most associate with the term. The Buffalo Bore hard cast loads are an excellent option for anyone contemplating using the 10mm Auto for hunting.

Users must be aware that some 10mm Auto loads are watered down resembling 40 S&W velocities. Not the case with the loads tested for this article. For example, the recently introduced Federal Premium 180 grain Vital Shok Trophy Bonded 10mm Auto shows the cartridges potential. The bullet used with the Federal load is based on the proven Trophy Bonded Bear Claw rifle bullet and features a jacket with formed inner profile that controls expansion to ensure deep penetration. The load features a 180 grain bullet that leaves the muzzle at 1,275 feet per second (fps) compared to the usual 1,030 fps of many manufacturer offerings. The Federal load delivers 650 foot-pounds of energy which puts it roughly between the 357Magnum and 41Magnum for comparison purposes. This kind of power offers great flexibility for the user in terms of use in a personal defense or hunting of medium sized game.

Premium 10mm Auto loads from Hornady were used consisting of 155 grain XTP and 175 grain FlexLock Critical Duty. These Hornady loads were designed with personal defense in mind with XTP and Critical Defense bullets loaded to 1150 to 1250 fps. The Critical Duty’s FlexLock bullets have a heavy jacket and a harder, high-antimony core designed to defeat barriers. The jackets are locked to the core via the same InterLock process the company uses on its centerfire rifle bullets. Hornady has also taken full advantage of recent advances in propellant technology use low muzzle flash powder in Critical Duty ammunition. Hornady Critical Duty FlexLock bullet balances barrier penetration with proper expansion in the target for maximum effectiveness. Hornady Critical Duty passed all five of the FBI’s barrier criteria tests giving 12 inches plus of penetration no matter if through glass, sheet metal, heavy clothing, drywall, and plywood while still expanding for maximum wound channel as well as not passing through the ballistic gel test medium. FlexLock bullet nose prevents the hollowpoint from deforming or clogging when passing through barriers. The ogives of the Critical Duty bullets do not taper as much as compared to other hollowpoints bullets, which improves feeding characteristics in autoloaders. The nickel plated cases are another attention to detail nod that limits drag into or out of a weapon’s chamber limiting chance for failure to feed or extract. Critical Duty, as the name implies, was designed for law enforcement in mind. However, security conscience citizens would be amiss not to at least consider it for use as well.

Top Sequence: Hornady 155 grain XTP clocked 1242 fps in G29, 1309 fps in G20, and a blistering 1406 fps in G40 MOS.

Another positive associated with any GLOCK product is the availability of supporting products, especially when it comes to holsters. BlackHawk! and Galco holsters were chosen to support the GLOCK 10mms during T&E sessions. Much anticipation awaited firing the three GLOCK 10mms in terms of recoil and muzzle blast. Range T&E took place at Echo Valley Training Center (EVTC). The Federal Vital Shok 180 grain Trophy Bonded 10mm Auto and Buffalo Bore were the stoutest loads, but in no way harsh or unmanageable. Anecdotally, empty brass was ejected briskly several feet away such was the slide velocity. The GLOCK polymer frames were appreciated for absorbing and mitigating felt recoil. Even the more compact G29 proved no problem. EVTC TacStrike steel targets were rocked with a more substantial smack than a typical handgun round. While one was definitely aware you were not firing a 9mm, recoil was not prohibitive with accurate rapid shots possible. As anticipated the larger G40 MOS was the smoothest. All of the 10mm Auto loads tested had no issue penetrating windshield or car body sheet metall. This is the type of performance and barrier penetration capability that the 10mm Auto was designed for. Further range testing consisting of dumping multiple magazines at several targets in rapid fashion.

Each GLOCK was tested fired through a chronograph to determine the effect of barrel length on velocity per specific load. Velocity gain between the 3.7 inch G29 and 6 inch G40 MOS was in the 100-120 feet per second range. For example, the Buffalo Bore 180 grain JHP clocked in at 1320 fps from the G29 and 1445 fps from the longer barreled G40 MOS. The Hornady 155 grain XTP chronoed 1242 fps from G29, 1309 fps with G20, and 1406 fps out of the longer barreled G40 MOS.

EVTC facilities were taken advantage of when evaluating the G20, G29, and G40 MOS by working in, around, and thru range vehicles. IPSC cardboard targets were placed within vehicles so that the 10mm Auto power could be judged thru automobile sheet metal, side glass, and windshield. In conjunction with this targets were arrayed in front of a range vehicle with the GLOCKs used to engage through the windshield from the front seat.

The G20 sights were left factory standard with TRUGLO TPX sights installed on the G29. The TRUGLO TPX iron sight combines fiber optic with tritium. This enhances visibility in daylight as well as at night. The TPX sights are CNC machined from steel for durability. The G40 MOS’s ability to mount red dot optic was taken advantage of by mounting a Trijicon RMR. This approach allowed an exploration of the different sight systems. The standard GLOCK factory sights are a known commodity and serve their purpose. There is no doubt that the TPX sights draw your eye to the front post; something most firearms instructors advocate for effective aiming. TRUGLO has further reinforced this by installing a white locking retention ring on the front sight to contrast with black retention rings around the two vials in the rear sight. The rear TPX sight is wider compared to a standard sight allowing for daylight around the front sight for more precise aiming and allowing for easier tracking of the target. A six o’clock hold produced tight groups at 15 yards seemingly on top of the front post. The TRUGLO sights stayed solid after hundreds of rounds fired with the G29. The TPX sights are a definite performance enhancement worthy of considering for retrofitting other carry handguns with.

LEFT: A variety of 10MM Auto was accessed/available for use in T&E of the three 10MM Auto GLOCKs.

The RMR equipped G40 MOS came into its own for precise fire at any range desired with placing the dot on the target and applying correct trigger control. The G40 MOS demonstrated the ability to hit steel man popper targets at 50 yards with amazing efficiency and even out to 100 yards with regularity. Speed drills involving plate racks and dueling trees were run with times more similar to a pistol caliber carbine than a handgun. The advantage offered by use of red dot sights in the competition environment is well known. The ability to place the RMR dot on the plate and not having to align front and rear irons proved adept at moving rapidly from plate to plate. The G40 MOS was also fired using the standard adjustable GLOCK sights that arrived on it. As expected the longer sight radius proved beneficial.

The inherent familiarity most have with the GLOCK platform, not to mention its ergonomics, validates anyone’s decision to chamber it in 10mm Auto. It is best to think of the GLOCK line-up of handguns as a “system” stretching from the mini G42 thru the G40 MOS. This was quickly evident when handling the G20, G29, and G40 MOS. While the balance and weight may change between each, the position of the slide and magazine releases will instantly be familiar. The key here is the similar trigger pull and feel found on the GLOCKs. Simplicity should not be confused as lack of refinement. As experience and knowledge expands, GLOCK reliability and solid performance has become more entrenched as the standard. There are many tactical situations in which the penetration and power of a 10mm Auto fired from a GLOCK type weapon could be very advantageous. Is the GLOCK 10mm Auto a prime weapon for all situations or users? Of course, not; however as a duty, personal defense or hunting handgun it is hard to beat thanks to powerful chambering and superior capacity. All of the GLOCK 10mms places real power in an accurate and reliable handgun package. The ability to reliably engage targets out to 100 yards was a pleasant surprise; the red dot equipped G40 MOS greatly expands assumptions about handgun effective range pushing the handgun operating envelope. The GLOCK G20 and G29 represent good balance of features for daily use as a duty or concealed weapon. After all, at its origin the 10mm Auto was designed specifically as a fighting cartridge. Each of the 10mm Auto GLOCKs allows a user to indulge oneself by having something out of the ordinary, while maintaining
sound functionality.

Barrett has taken its vision of the AR rifle another step forward with its new direct impingement AR. Interestingly, the REC 7 DI is Barrett’s fourth AR pattern rifle; the first being the Barrett M468 rifle, which also employed a direct gas-impingement system. The M468 was subsequently discontinued from production. The second Barrett AR was the piston driven REC 7 in 2007. The Barrett REC 7 II, which tweaked the original REC 7, can be considered the third Barrett AR variant. Barrett will continue to produce the piston driven REC 7 alongside the DI variant; the best of both worlds for the AR user.

It is not unusual to see military pattern weapons embraced by civilian shooters outside of the armed services. This pattern can be discerned even before the AR rifle arrived on the scene à la the Trapdoor, Springfield, M1 Garand etc. Why not take advantage of the time and effort expended by various nations’ armed forces in doing the initial leg work of what works in terms of reliability and effectiveness. This is not to say military weapons are to be blindly followed; just that millions of dollars and countless hours of research & development should not be ignored as a starting place. The AR’s modular nature combined with advances in CNC machine technology allows for enhancements beyond what could have been imagined 50+ years ago. This same concept can be applied to cartridges chambered in the AR.

.300BLK provides superior barrier penetration compared to standard 5.56MM cartridge.

Of late, much attention seems to be on “improving” the AR platform via cartridge enhancement. The .300 Blackout (.300BLK) is emerging as one of the most successful alternate AR chamberings. Reports from our ongoing war against terror combined with near constant operational tempo in Afghanistan and Iraq have re-exposed 5.56MM poor performance in putting an adversary down quickly with minimal rounds fired. While the basic AR15/M16 design is hard to improve upon when it comes to reliably launching bullets downrange accurately, many lament the 5.56MM caliber. Though the 7.62x51MM/ .308Win AR10 has been around for quite some time, the .308Win AR’s increase in size and weight in terms of necessary AR receiver size, ammunition, and other accessories to accommodate the larger cartridge is a draw back to many. The last frontier with the AR is caliber expansion that fits within a standard 5.56MM lower receiver. Combine this with the increasing use of suppressors and the stage is set for an AR chambered in a cartridge capable of supersonic and subsonic factory loadings. This is where an AR chambered in the .300 Blackout (.300BLK) comes into the story.

The .300BLK (7.62x35MM) was introduced by Advanced Armament Corporation (AAC) in cooperation with Remington Defense in response to the US special operation military forces discussions. Literature illuminates their goal with the .300BLK as being the ability to launch .30 caliber projectiles from the AR platform from existing 5.56MM magazines without a reduction in magazine capacity or reliable functioning. Another notable characteristic of the .300BLK is its compatibility with the AR standard bolt; thus only a barrel change is necessary. Anecdotal information compares standard velocity .300BLK 115-125 grain ammunition as matching the ballistics of the 7.62x39MM AK and eclipses 5.56MM both in ballistics and terminal punch. At 300 meters, the .300BLK has approximately 17 percent more energy than the 7.62x39MM. The .300BLK from a 9 inch barrel has the same energy at the muzzle as a 14.5 inch barrel 5.56MM M4 and surpasses it as ranges extend. One interesting twist with the .300BLK, obvious considering AAC is in the suppressor business, is the ability to choose subsonic loads for optimal use with a sound suppressor. The ability to access either supersonic or subsonic factory ammunition offers great flexibility to the .300BLK AR user; especially considering the special attention paid to its compatibility with the AR platform.

American Eagle Suppressor 220 grain OTM ammunition produced tight 50 yard grouping when fired with or without Barrett suppressor attached.

The REC 7 DI evaluated herein is chambered in .300 Blackout (.300BLK). 5.56MM and 6.8 SPC are other cartridge options. Talks with Barrett’s Director of US Commercial Sales, Jeff Burch, indicated that the 5.56MM and 6.8 SPC REC 7 DI rifles will have either 16 inch or 18 inch barrels with a DMR model in the works. The .300BLK DI will be offered with 16 inch or 10 inch barrels. Barrett’s AM30 suppressor was used in conjunction with the REC7 DI to fully explore what the .300BLK Barrett REC 7 DI offers. The Barrett suppressor is made from titanium alloys and measures 8.3 inches with 1.5 inch diameter. Weight is 12.4 ounces. Sound reduction is rated at -25-30dB.

The same Barrett quality and attention to detail in providing accurate, rugged, and reliable weapons such as the MRAD and 98B, both examples of other Chris Barrett designs, was turned toward the AR. For example, the Barrett Enhanced Bolt is made from high-strength 9310 steel. Every bolt is proofed and magnetic-particle inspected to guarantee reliable performance. The REC 7 DI upper and lower receivers are forged from 7075 aluminum upper and then hardcoat anodized. An ALG ACT trigger is standard with the REC 7 DI. A proprietary Barrett muzzle brake of Chris Barrett’s design is threaded to the 16 inch free-floated, Match stainless barrel with M4 feed ramps machined into the receiver and the barrel extension. Barrett is profiling and chambering barrel blanks for the REC 7 DI barrel enabling tighter quality control and smoother supply chain. Magpul MOE adjustable buttstock is fitted to the REC 7 DI. The REC 7 DI weighs 6.5 pounds and measures 32.5 inches with stock collapsed and 35.75 inches extended. The REC 7 DI features Cerakote finish. Available colors are ODG, tungsten gray, tan, and black. The rifle evaluated herein features a custom paint job.

Suppressor use dominated testing with the Barrett REC 7 DI. Suppressor use is often the bane of direct impingement ARs due to the increase in fouling caused. The Barrett never faltered no matter type of ammunition used.

The REC 7 DI tested arrived with Barrett’s new BRS (Barrett Rail System) forend. It is a free-float hand guard that helps trim 4 to 7 ounces of weight of the rifle. The BRS is available as a stand alone accessory from Barrett. The REC 7 DI is one of lighter AR versions on the market, especially considering that it features a full length rail and 16 inch barrel, weighing less than 7 pounds. The low profile gas block found on the Barrett REC 7 DI is machined from heat-treated tool steel and is lighter than standard gas blocks. The Barrett REC 7 DI shows versatility in satisfying customer needs by not using full length quad rails, but instead a lower profile handguard. The BRS handguard minimizes weight and contributes to the excellent balance of the REC 7 DI. Some full length rails cause a front heavy feel. Side benefits of the BRS consist of effective cooling of the barrel, secure mounting of sling swivels and other accessories deemed necessary. The minimalist approach of the BRS still allows plenty of room for VFG, bipod and lights/lasers if so needed. Barrett’s decision to produce its own forward rail system for the REC 7 DI in lieu of using one from another manufacturer is a further commitment of ensuring production capability and quality.

Chris Barrett decided to include several nuances with the REC 7 DI to separate it from other rifles on the market. A BCM Gunfighter charging handle shows Barrett’s effort in improving user manipulation of the rifle. Inexpensive charging handles tend to twist and bend when put under stress as expected with a rifle designed for hard use either in training or deployment. Along these same lines Barrett has chosen to nickel boron the bolt carrier to further enhance the reliability of the REC 7 DI.

EVTC’s “jungle walk” firing venues allowed for a variety of supported firing positions.

Ammunition tested with the Barrett REC 7 DI Ammunition was Hornady supersonic 110 grain VMax and subsonic 208 grain AMax. American Eagle Suppressor 220 grain OTM ammunition was also used. While the Hornady ammunition is listed as .300Whisper on their webpage, a notation on the box clearly states it is usable in a .300BLK. In fact, Hornady utilizes .300WSPR/BLK labeling on its boxes. The .300Whisper predates the .300BLK and is dimensionally very similar. However, prudence dictates caution of any interchangeability unless clearly noted as with the Hornady loads. The .300Whisper is a J.D. Jones trademarked round dating back to 1992. A whole article can be dedicated to discussing the .300BLK and .300Whisper. In short, the .300BLK is a SAAMI standard cartridge and the .300Whisper is not.

The Hornady and American Eagle loads were chronographed. The Hornady 110 grain averaged 2315 fps and 208 grain 1010 fps from the Barrett 16 inch barrel. American Eagle Suppressor measured 1020 fps. A Leupold Mk 4 1.5-5x optic was mounted. Accuracy from a “bench” position with the Barrett REC7 DI measured slightly over 1 inch at 100 yards. The American Eagle Suppressor brand ammo produced tight clusters at 50 yards. This accuracy level justifies considering leaving a magnified optic such as the versatile Leupold Mk 4 1.5-5x mounted on the REC 7 DI. Several magazines’ worth of ammunition was spent engaging plate racks and man-sized steel targets with the Barrett REC7 DI. Drills quickly moved past stand and deliver drills to more dynamic drills involving movement, magazine reloads, and firing from behind cover. The Barrett DC30 suppressor was used frequently during the drills. After all that is the point AR rifle chambered in .300BLK—suppressor use.

Barrett’s thought process with the REC 7 DI was to create a lightweight, simple to operate AR rifle similar to Eugene Stoner’s original concept. The flexibility to also chamber it in 6.8SPC and .300BLK is a nod to realism that 5.56 MM is not the only viable option for entities with the option/motivation to choose other wise. All Barrett REC 7 DI features are intended for maximizing effectiveness during a fight or realistic training on the range. The key component in a fighting rifle is reliability. No matter how accurate or powerful chambering a rifle is if it does not work 100% of the time it is a liability. Selection of a fighting rifle is as personal as it gets. The Barrett REC 7 DI is intended for serious practitioners who plan on using it for patrolling, training, or defense. A return to AR basics such as lightweight, great handling with potent firepower is often the answer. Barrett offers such a platform with its REC 7 DI.

DPMS offers one of the broadest catalogues of AR rifles on the market with a dizzying array of AR model types, calibers, and configurations. The DPMS AR rifles cover the gamut in terms of mission profile and adaptability for the user. DPMS was founded by Randy Luth in 1985 as a precision machine shop for manufacturing M203, M14 and M16 parts for U.S. military contracts. He also developed and manufactured numerous patented accessories. DPMS eventually expanded into producing their own complete AR type rifles. Cerberus Capital Management, a private equity investment firm, purchased DPMS Panther Arms in December, 2007, thereby combining DPMS with Bushmaster Firearms International, Remington Arms and Cobb Manufacturing to form the Freedom Group.

In general terms, ARs come in two patterns: AR-15s and AR-10s. The AR-15 is most associated with 5.56mm/.223 Rem. and the AR-10 with 7.62NATO/.308 Win. The DPMS GII SASS reviewed herein joins the growing number of AR style platforms chambered in .308 Win. However, the DPMS GII SASS will change users’ thoughts on how an AR-10 rifle can be configured. While we will focus specifically on the DPMS .308 Win. GII SASS AR-10 for this article, DPMS currently offers six GII AR-10 models. What separates the DPMS GII ARs from other .308 Win. AR-10s? Often the AR-10 pattern rifle is associated with an unwieldy profile weighing 12 pounds or more. There are DPMS GII models that weigh less than 8 pounds. DPMS has made a conscious effort with the GII model to blend typical AR-10 and AR-15 components to allow for wider access to AR-15 accessories while exploiting .308 Win. power. Forged upper and lower receivers are contoured to be more ergonomic while only 1/2 inch longer than an AR-15 receiver and 5/8 inch shorter than typical AR-10s. Their attention to detail is further borne out with a reduced mass bolt carrier. This provides a smoother, softer recoil impulse compared to most other .308 Win. AR-10 weapons on the market. The GII SASS accepts AR-15 type handguards thanks to a newly designed barrel nut. This pattern is followed with the GII SASS’s AR-15 type fire control unit for more accessory adaptability. DPMS GII AR rifles incorporate an inserted steel feed ramp, allowing a lighter, smaller barrel extension and receiver, while improving feeding of more ammunition types and have lengthened the ejection port allowing for more consistent ejection of fired empty cases. This focus on reliability is supported by DPMS redesigning the gas impingement delivery system, monolithic bolt carrier and optimized gas ring clearances to eliminate the possibility of gas leakage during operation. The new bolt geometry provides superior lockup and strength by allowing for a smaller diameter barrel extension to be used reducing overall material and weight without compromising strength. In short, contoured steel feed ramps, redesigned extractor with elastomer extractor spring, dual ejectors, and other design tweaks found in the GII SASS all serve to decrease feeding, extraction and ejection malfunctions that can plague some AR-10 designs.

The GII SASS reflects modern trends of utilizing night vision with night vision devices easily mounted. The ATN PS22 NVD mounts in front of day optic. The Schmidt & Bender PM II Ultra Short design had just this application in mind with its design.

The DPMS GII SASS is a precision rifle that even though a semiautomatic, produces accuracy equal to most tactical bolt action rifles. DPMS literature points out that the SASS (Semi Auto Sniper System) was designed to provide military marksmen a rifle that could accomplish long range precision missions, especially in a target rich environment, while providing an effective volume of defensive fire for close range encounters. The DPMS SASS emerged in response to a U.S. Army solicitation in the early 2000s with trials held in 2005. Though another manufacturer was awarded the Army contract, DPMS decided to offer a version of their SASS entry to law enforcement and civilians.

The GII SASS features an 18-inch fluted 416 stainless Teflon coated 1:10 twist medium contour barrel, threaded muzzle with Panther flash hider, forged 7075 T6 Anodized upper/lower receivers, Magpul PRS stock, Magpul back-up iron sights, DPMS two stage Match trigger, mid-length direct impingement gas system, Panther tactical grip and 4 rail free float tube. The DPMS GII SASS is 30 percent lighter than its DPMS LRT SASS predecessor. The GII SASS tips the scales at 10.5 pound and measures 39 inches. The GII SASS represents an excellent balance of weight for minimizing felt recoil and provides a stable rifle platform for increased accuracy potential while maintaining a semblance of handling. The GII SASS being direct impingement in operation versus piston driven further eliminates weight and provides for a balanced rifle compared to being front heavy as some piston rifles can be. If you are looking for a flexible multi-mission rifle for yourself or agency, the GII SASS should be among those considered. The GII SASS rifle is designed to excel in a fluid task environment by accommodating a wide variety of accessories.

A Meopta MeoSight red dot was affixed to the GII SASS via a Weaver 45 degree offset mount bracket. This offers users an efficient CQB sighting option.

A DPMS metal magazine comes with the GII SASS. However, Magpul PMag 20 LR/SR 7.62 magazines will also work. This is a huge plus. Magpul’s PMag 20 LR magazine is quickly becoming the standard .308 Win. AR magazine with several manufacturers setting up their lowers to utilize the Magpul product. Quality magazines are a linchpin for a reliably functioning semiautomatic or select-fire weapon.

A DPMS free floated rail system surrounds the barrel. The DPMS railed forend, in conjunction with railed flat top upper receiver, allows for mission specific configuration with lights, lasers, target designators, night vision devices and other items.

A key point with the DPMS GII SASS is superior out of the box accuracy without having to resort to a full-blown trip to an agency armorer or outside gunsmith for tuning. The GII SASS takes a back seat to no rifle in terms of precision, repeatable accuracy, capacity, ergonomics, reliability, trigger, and safety. The first requirement of a tactical rifle is precise accuracy. The GII SASS tested constantly produced sub-MOA groups with multiple 168 grain ammunition brands – an important logistic consideration. The Magpul Precision Rifle Stock (PRS) is adjustable for length of pull and comb height, plus offers a rail on the bottom of the stock for a monopod attachment. The Magpul stock is rock solid with design characteristics making it conducive to long range shooting from the prone position using improvised shooting rests or bipod. The PRS’s hook style buttstock allows a shooter to “crawl” into the scope and hook his offhand around the buttstock for a more steady hold. The ergonomics of the stock allows for a comfortable, repeatable cheekweld combined with hand placement conducive to pulling the Match trigger smoothly. DPMS includes a stud rail attachment for the railed quad rail and a Harris bipod with the GII SASS. The moderate weight of the GII SASS allows for offhand and other types of supported fire if needed. Some of the precision tactical rifles coming on line today reflect more of target shooting heritage than tactical weighing over 16 pounds. The GII SASS’s 10 pound weight translates into a rifle that can be carried afield without fatiguing the marksman and is easier to adapt to non-standard firing positions even offhand if needed. The 18-inch medium profile barrel is a solid compromise balancing weight, performance, and field handling for the tactical marksman. The GII SASS had no problems with shifting points of aim even when firing a full magazine of twenty aimed rounds in relatively rapid fashion.

The DPMS GII SASS arrives out of the box as shown.

A Schmidt & Bender (S&B) 5-20×50 PM II Ultra Short was mounted on the GII SASS via a Recknagel quick release mount. The S&B had a Tremor 2 reticle. Further tactical modification of the GII SASS into a lowlight/dark role is satisfied by mounting an American Technologies Network ATN PS22 Night Vision device in front of the Schmidt & Bender scope. This multi-use ability keeps day scope constantly zeroed, yet allows for quick adaptation during a night mission. This eliminates the need for a separate dedicated weapon system exclusive to night vision tasks or having to constantly remove day optics from a rifle and replacing with a NVD. The PM II Ultra Short design had just this application in mind with its design. The ATN PS22 serves as a force multiplier when employed on the GII SASS. The forend also has side rails for mounting IR illuminators used in conjunction with the NVD device or intense tactical white lights if NV is not used. The GII SASS reflects modern trends of utilizing night vision with night vision devices
easily mounted.

Various .308 Win. loadings from Black Hills Ammunition, Federal, Winchester and Hornady provided the basis of accuracy tests. The Black Hills Match loads tested consisted of 168 grain Match bullets. The Federal chambering was the venerable 168 grain Match load. 168 grain TAP from Hornady and 168 grain Match from Winchester was also tested. The GII SASS’s 18-inch barrel with the 168 grain loads clocked 2,550 feet per second. As to be expected with quality ammunition, velocity figures within the different loads deviated very little from round to round. This is critical for predicable long range accuracy.

The DPMS GII SASS is equipped with a free floated quad rail allowing users to set it up as they see fit.

The GII SASS shot all the premium 168 grain loads tested into 1 MOA or better at 100 yards. Many will scoff at this as typical gun writer fluff. Obviously, the best ammunition brands and loads where utilized. Black Hills Ammunition, Federal, Winchester, and Hornady are industry leaders, which is what this type of rifle deserves to wring out its full potential. The testing was done off a bench supported by Harris bipod and Champion shooting bags. The Federal 168 grain Match, Winchester 168 grain Match, and BHA 168 grain Match produced the best 100 yard average with all producing slightly over 5/8 inch averages. The accuracy figures are based on firing 3 three-round groups and averaging group sizes. Another sign of an accurate, dependable rifle is how cold bore zeros compare over time and if the point of aim shifts after a few rounds heat up the barrel. The DPMS GII SASS showed no shifts in point of aim and cold bore zeros produced fine groups when overlaid together.

Not much time was spent at the 100 yard range. After verifying innate accuracy from the bench, field tests were performed at Echo Valley Training Center (EVTC). Echo Valley Training Center is properly set-up to handle extensive test firing of a precision tactical rifle like the GII SASS. In conjunction with the individual training bays, EVTC features multi-stepped target berms that are strewn with reactive steel targets, fluid drained automobiles, and moving targets at ranges varying from 150 yards out to 350 yards. Echo Valley Training Center is further enhanced by the existence of prepared firing positions. This allows for more realistic prone and “dug-in” trench-style firing points consisting of concrete culverts turned on end and buried. These firing positions and target arrangements are ideal for all types of training scenarios with most types of weapon systems including precision tactical rifles. 300 yards and out is the more indicative test of a precision tactical rifle. The Federal 168 grain Match and BHA 168 grain Match loads performing the best again. Another note of interest was how easy the Tremor 2 reticle inside the Schmidt & Bender made hitting targets at the 300 yard pit. A 100 yard zero easily translated into holding the first Mil-hash below the main horizontal wire directly on target causing hits at 300 yards. The benefit is obvious of holding directly on target versus an estimated hold over. Also, the Tremor 2 reticle is a great tool for range estimation and target engagement. The Tremor 2 offers more than a strictly Mil Dot pattern reticle. The Tremor 2 features various sized and spaced hash marks on the vertical and horizontal stadia for increased ranging precision, accuracy, and quick range estimating reference points.

While designed for long range accuracy and reliability in mind, the DPMS GII SASS was also proofed with Meopta MeoSight in close range scenarios.

With the GII SASS proving it was more than capable of connecting with TacStrike steel targets arrayed along Echo Valley Training Center’s stepped berm out to 300 yards, it was decided to try something out of the norm by working with the GII SASS inside EVTC’s 360 range. It was a simple matter of keeping the S&B optic in place and mount a Meopta MeoSight red dot via a Weaver 45 degree offset mount bracket. This allows a quick rotation of the rifle in the shoulder pocket a few degrees accessing the red dot optic with minimal effort or disturbance of handling. This made the GII SASS much more efficient at engaging targets at close distances. Drills started out slow working around simulated cover while engaging designated targets in and around range vehicles to allow evaluators to get a “feel” of the rifle. Scenarios where then set up to force magazine changes as well as moving to various firing points. Eventually, the GII SASS was moved to within vehicle confines where evaluators fired on targets from the range vehicles as well as quickly exiting the car while maintaining rounds sent downrange. While not your typical fare for an 18-inch barreled .308 Win. AR-10 type rifle, the GII SASS proved more than capable of sending rounds downrange quickly and effectively; certainly better than a five round bolt action rifle would be. This was done to verify if the SASS concept was valid in terms of providing extended range precision fire as well as volume of fire if pressed into use at closer distances.

The DPMS GII SASS proved reliable and accurate throughout this evaluation with approximately 250 rounds fired, some of them rapidly, without cleaning during multiple range visits. Evaluators came away with a positive attitude towards the GII SASS delivering on its promise of being a lighter more maneuverable AR-10 type rifle. With that said, there is no mistaking that you have an AR-10 in your hands versus a svelte 6 pound AR-15. One can tell the GII SASS was an AR-10 even if you were testing it next to a 10 pound AR-15. This stems from balance and overall feel of the GII SASS due to weight distribution found in the receiver and bolt group, which is only magnified when a 20 round magazine of .308 Win. is inserted. This is not a knock against the GII SASS – just a fact of physics. Along these same lines, your shoulder and face come away knowing you have fired multiple magazines of .308 Win. compared to 5.56mm. On a positive note steel targets are struck with awesome authority when 150+ grains smack into them, especially from a close distance.

The DPMS GII SASS covers the gamut of likely situations encountered by law enforcement or security conscience civilian with equal aplomb. This is a reflection of DPMS design tweaks in the GII series and use of the .308 Win. chambering. DPMS experience and industry leading developmental commitment is shown with the enhancements made to the GII series as typified in the SASS model.

A Schmidt & Bender 5-20x50 PM II Ultra Short was mounted on the GII SASS via Recknagel quick release mount. Schmidt & Bender has become the optic of first choice for many elite units with scopes available for precision long range accuracy as well enhancing other types of weapon platforms.

The DPMS GII SASS could be the answer to fulfilling a multitude of roles – precision rifle or general-purpose patrol rifle. The DPMS SASS was fitted with a Schmidt & Bender magnified optic and Meopta red dot sight for this T&E. A US Palm Gen 1 Multi Platform Attack Rack further supported testing.

It is no secret that the Eugene Stoner’s AR platform is the best selling rifle in the U.S. with many manufacturers jumping on the bandwagon in recent years by offering their versions. It seems the ARs adaptability attribute is also its most abused quality. Primary Weapons Systems (PWS) is seeking to counter balance this trend towards over accessorized ARs with their “Modern Musket” direct impingement AR. That is right, PWS, the standard bearer for the long stroke piston driven AR, has introduced a direct impingement AR platform.

The Modern Musket joins PWS’s existing MK1 5.56mm, MK2 7.62x51mm long stroke ARs, T3 rimfire, and recently introduced MK3 Precision Bolt. PWS is known as a leader in the quest for improving the AR operating system and cultivates an almost cult following based on superior customer service, unique interaction style with consumers and, most importantly, coming through on their promise of a superior AR rifle. PWS did not hang their hat on going with the typical short stroke piston in lieu of Stoner’s original direct impingement (DI) AR design; they took the less traveled path by utilizing a long stroke operating piston. We will define long stroke as exemplified by the AK47 of having op rod connected to the bolt carrier whereas short stroke consists of a more complex arrangement of tapped gas imparting force to an op rod that impacts another part of the mechanism that acts on the bolt carrier. PWS did not stop with the long stroke piston in their tweaking of the AR; rather they insisted on top quality components as well modifying the buffer tube connection to the receiver as well as bolt carrier design.

The PWS Modern Musket rifle was used from barricades and simulated cover while engaging multiple targets.

While PWS long stroke AR rifles are well-known and respected, their entry into the direct impingement AR market is presently still relatively unknown. In the world of modern marketing it is nice to discover a product in the catalogue you feel should be the main story. The PWS Modern Musket is such a product. Any law enforcement agencies, security conscience citizen, or modern sporting rifle (aka AR-15) connoisseur should consider the PWS Modern Musket. PWS has chosen to take advantage of lessons learned with their long stroke MK1 and MK2 ARs and apply this to the Modern Musket.

The homage paid by naming their new DI AR Modern Musket is based on the AR’s ever growing popularity in the U.S. market as well as PWS’s belief that every freedom loving American should own an AR just as we depended on gun ownership at the birth of our nation’s independence. The same PWS principles that guided their long stroke AR journey are present in the Modern Musket. Only after a thorough survey of the topic did PWS move forward. The Modern Musket DI-16 tested for this article is chambered in .223 Wylde. A quick word about the DI-16’s .223 Wylde chambering is in order. The .223 Wylde was designed as a match chambering for semiautomatic rifles. It will accommodate both .223 Rem. and 5.56mm ammunition. It is relieved in the case body to aid in extraction and features a shorter throat for improved accuracy. As most know, the 5.56mm is not synonymous with the .223 Rem. chambering. Generally, it is advised as acceptable to fire .223 Rem. in a 5.56mm, but not the other way around. The .223 Wylde was meant to give a slightly tighter body spec than 5.56mm, but a bit looser than .223 Rem., while retaining a longer lead/throat. In effect, the .223 Wylde is a hybrid splitting the difference between the 5.56mm and .223 Rem. while extending benefits in terms of accuracy and reliability.

The Modern Musket is a no nonsense AR rifle. PWS chose to use a Magpul MOE buttstock and pistol grip with the Modern Musket. The collapsible buttstock is easily adjusted for length of pull and/or transport. It is also one of the lighter AR versions on the market, especially considering that it features a full length rail and 16-inch barrel, weighing less than 7 pounds. The low profile PWS gas block found in Modern Musket rifles is machined from heat-treated tool steel and is much lighter than standard low profile gas blocks helping to shave weight. A minimalist PWS KeyMod rail design measuring 15 inches further assists in weight savings. The PWS rail system permits the barrel to be free floated for better accuracy. The Modern Musket shows versatility in satisfying customer needs by not using full length quad rails, but instead a lower profile handguard with adjustable KeyMod Picatinny rail sections. The KeyMod handguards minimizes weight and prevents the Modern Musket from being front heavy impacting handling, yet allows for effective cooling of the barrel and secure mounting of sling swivels and flashlight attachment interface. The minimalist approach for rails still allows plenty of room for VFG, bipod and lights/lasers if so needed. Not all weapons need rails and an array of accessories to be considered viable. It is often best to let the end user how to set up their specific rifle.

The DI-16 variant features a 16-inch 1:7 twist barrel contributing to an overall length of 36.5 inches with stock extended and 33 inches collapsed. PWS uses high quality chrome moly barrel blanks that they turn themselves; then Isonite treated inside and out for hardness and corrosion resistance and then threads on their proprietary muzzle device design. The rifle weighs 6 pounds 12 ounces pounds empty. The trigger used with the Modern Musket is a definite upgrade over typical Mil-Spec variants; it is an ALG Defense’s Quality Mil-Spec trigger for a smooth pull and a crisp break.

A supplied Lucid HD 7 is a nod to realism that red dot sights are here to stay. Most will add flip-up back up iron sights for peace of mind.

PWS’s experience in developing their piston ARs is carried over into the Modern Musket. They eliminated the typical AR castle nut method of attaching the carrier tube to the lower receiver using indexing screws instead. PWS has designed an enhanced buffer tube with an extended lip to support the carrier at rest, allowing for smooth entry into the buffer tube upon cycling of the action. The buffer tube has QD sling attachments machined directly into the aluminum, is enhanced with four integral drain holes in addition to a rear drain hole thus allowing more water to escape the system, as well as fluting for more debris tolerance in adjusting the Magpul rear stock. Lastly, their buffer tube uses a H2 buffer consisting of a tungsten weight housed in a steel body coated in nickel Teflon for reduced friction.

The Modern Musket’s bolt carrier is precision machined, Isonite treated and sport unique features that increase the reliability of the DI AR-15 platform. These features are increased mass to extend dwell time and delay unlock. As a result, the PWS bolt carriers allow chamber pressure to be greatly reduced for easier extraction. Gaps and channels between skid pads allow for fewer points of contact within the receiver thus resulting in less friction and keeps debris from interfering with function. A BCM Gunfighter charging handle tops off PWS’s effort in improving the bolt carrier by giving the user better purchase in manually operating the Modern Musket’s bolt. Inexpensive charging handles tend to twist and bend when put under stress as expected with a rifle designed for hard use either in training or deployment.

The PWS KeyMod handrail maintains adaptability while streamlining the forend as well as allowing the barrel to be free floated on the Modern Musket.

PWS’s most significant upgrade for the Modern Musket is shipping it standard with Lucid’s HD 7 red dot optic mounted on the upper receiver’s flat top rail. Let’s face it – customers will end up foregoing iron sights as the primary means of aiming their Modern Musket and mount a red dot of some sort. PWS accepts this truism and equips the Modern Musket with a sound choice for a red dot straight out of the box. End users can still mount back up iron sights of their choice with Magpul sights the most likely option. Water proof, shock proof and fog proof, the 13 ounce Lucid HD 7 red dot sight allows users to cycle through four different reticles and is covered by a lifetime warranty. Lucid founder, Jason Wilson, was convinced there was a market for simple, reliable optics at an economical price. MSRP for the Lucid HD 7 is $249. His plan was to design a scope here in the United States, and then manufacture it overseas to keep the price reasonable. The Lucid HD 7 features a rubber-armored aluminum body, lower 1/3 co-witness for your AR-15’s iron sights and an integral scope mount. The Lucid HD 7 takes a single AAA battery that front-loads into the base of the unit and provides an estimated 1,000 hours of use. The HD 7 has a two hour auto shut off. On the left side of the base is the power button and up/down brightness controls featuring seven settings as well as an auto brightness setting. Also, on the left side of the HD7 is the reticle selection turret, which gives you four options: a 2-MOA dot, a 2-MOA dot surrounded by a larger circle, a crosshair, or a chevron. Elevation and windage turrets use 1/2 MOA adjustments.

Ammunition tested with the PWS Modern Musket was a combination of 600 rounds of Black Hills Ammunition, Federal Premium, American Eagle, Hornady TAP loads and Winchester 55 grain FMJ. Readers deserved to see what base line accuracy was like with the Modern Musket: thus, the decision to mount a Leupold Mk 4 3.5-10x scope before re-attaching the Lucid HD 7 for the remainder of the T&E. The Modern Musket kept all loads tested under 2 inches at 100 yards; this includes FMJ with premium loads hovering around inch groups. This accuracy level justifies permanently mounting a magnified optic such on the flattop upper if a user desires. Of course, a red dot optic such as Lucid HD 7 is viable as well. Accuracy test protocol consisted of 3 five-shot groups with each ammunition type and group sizes were averaged. Velocity figures ranged from 2,800 fps to 3,000 fps over a RCBS chronograph.

PWS’s bolt carriers have performance enhancing features such as increased mass, gaps and channels between skid pads, and a BCM Gunfighter charging handle.

With the magnified optic removed it was decided to expand normal T&E protocol. After sighting in the Lucid HD 7 at 50 yards, the PWS Modern Musket was taken to the Echo Valley Training Center’s (EVTC) 360 and “Jungle Walk” ranges. Training scenarios involving team tactics along with patrolling to contact allowed the Modern Musket to shine in terms of potent firepower and accuracy. Firing from unorthodox positions while working around range vehicles showed why the light weight PWS Modern Musket and Lucid HD 7 are such a good combination. The PWS is easy to manipulate and the HD 7’s red dot is not dependent on a specific eye relief distance to be effective in accurately placing rounds on target. The Lucid HD 7’s red dot sight assisted in engaging targets at close distances with the red dot easy to pick up rapidly. The HD 7 red dot sight offered the capability to engage multiple targets in rapid sequence compared to open sights, while at the same time providing adequate accuracy out to a couple hundred yards on man-sized targets yards due to the red dot not obscuring the target due to the dot not being that large.

A huge benefit of choosing an AR for use is the multitude of magazines available from various manufacturers. This author has come to trust Brownells for metal AR magazines and Magpul for polymer variants. The Magpul 40-round PMag is steadily growing as a favorite among the higher capacity AR magazine variants due to its track record of performance involving multiple weapon reviews. Along these same lines nearly every tactical webbing gear manufacture in the U.S. offers products to carry AR magazines ranging from chest rigs, vests, thigh subloads, belt pouches etc. Go-to brands are US Palm, High Speed Gear, Velocity Systems/Mayflower, and BLACKHAWK!. A simple offering from BLACKHAWK! is their bandoleer style pouch. It will appeal to many with its ability to accommodate two pistol magazines in conjunction with four AR magazines. The BLACKHAWK! bandolier can be grabbed in a hurry and slung over your shoulder while also hastily grabbing the Modern Musket. For civilians, four spare magazines plus one in the Modern Musket is plenty to solve most issues that would call for the PWS DI AR in
the first place.

All Modern Musket features are intended for maximizing effectiveness during a fight or realistic training on the range. The key component in a fighting rifle is reliability. No matter how accurate or powerful chambering a rifle is if it does not work 100% of the time it is a liability. As with any personal weapon, selection of a fighting rifle is as personal as it gets and individual preferences and prejudices will decide interest level in the PWS Modern Musket. The Modern Musket is intended for serious practitioners who plan on using it for patrolling, training, or defense. If you ever envisioned a scenario responding to a bump or other commotion and have to grab a rifle and bandolier of magazines on the way to respond, then the PWS DI AR is more than worthy of consideration of the Modern Musket nomenclature.
