XK8 5.56mm Assault Rifle

The XK8 5.56mm AR rifle is a bullpup rifle firing the SS109 bullet. The 3X optical scope and the laser designator ensure rapid shooting and high accuracy. The stock is made from a high-strength engineering plastic. It has a standard Picatinny rail that allows mounting of various optical sights and accessories. The flash suppressor’s unique design resists muzzle climb and minimizes flash exposure.

K2C 5.56mm Assault Rifle

The South Korean K2C is broadly equivalent to the U.S. M4 carbine. It’s the carbine version of the K2 and a more compact version with a shorter barrel and telescopic buttstock. The 310mm (12.2 inches) barrel has a 3-prong flash hider. The MIL-STD-1913 rails allow mounting for optics, lights and laser devices. The K2C has a stamped and welded sheet-steel construction rather than the use of machined forging techniques employed in the M16 assault rifle and M4 carbine. As a result, the K2C is built to looser mechanical tolerances, which also reduced the weapon’s production price. The K2C retains a number of the M16 and M4 design features, including a generally similar receiver and bolt group. However, this carbine has a different gas system which is more reliable.

K1A 5.56mm Submachine Gun

The K1A is used by South Korean special forces and soldiers, who do not need a full-size assault rifle. The K1/K1A short carbines were developed first. The full-sized K2 assault rifle was developed later. The K1A is the upgraded version of the K1 carbine (developed as a submachine gun to replace the M3 “Grease Gun” for the South Korean military and police forces for the South Korean military).

The K1A is considered a submachine gun by the South Korean military, despite the fact that it fires a 5.56x45mm NATO/.223 Remington cartridge like the full-sized assault rifle.

K7 9mm Silenced Submachine Gun

Its integral silencer reduces the pressure of the gas produced during discharge, and by extension, reduces the amount of noise generated.

In addition, the silencer significantly distorts the sound of the gunshot so that it is very difficult to pinpoint the location of the shooter. Per shot, the mean average of noise generated by the K7 is approximately 111dB noise. Some parts are compatible with the K1A submachine gun. The safety/selector lever—Safe, Semi, Burst (3 rounds) and Auto is one-handed. It’s a blowback-operated system with a fixed barrel. The stock is 3-position collapsible.

K11 20mm/5.56mm Dual-Barrel Air-Burst Weapon

The K11 is a dual-barrel air-bursting weapon (under and over barrel bullpup) system that combines the lethal 20mm air-bursting ammunition and 5.56mm NATO ammunition with an automatic electro-optical fire control system (FCS) to effectively defeat targets at extended ranges. The weapon is ergonomically designed with a high-strength AI and an Alloy upper receiver. The lower receiver and buttstock are polymer. The 20mm barrel with fuze setter is in Titanium alloy. The FCS has optical day sight with digital reticle, night sight with IR sensor, eye safe laser range finder, ballistic computer and environment sensors. The K11 can fire both 20mm and 5.56mm ammunition with the single trigger (Fire mode: 20mm single-shot mode, 5.56mm semiauto mode and 5.56mm 3-round burst mode). Moreover, the K11 can fire at point targets and especially hidden targets in a fox hole with 20mm air-bursting ammunition.  With such high level combat capability, K11 is certainly expected to be linked to future soldier systems. The 20mm air-bursting ammo has a turn count programmable air-bursting fuze. The warhead is two-layer preformed fragmentation.

This Korean weapon resembles another type of corner gun that was devised by two former senior officers from the elite units of the Israel Defense Forces, the Corner Shot. It’s a weapon system that allows the user to shoot around corners using a video screen to aim and a swiveling gun-mount that can rotate up to 90o. This corner gun can accurately engage targets up to 330 feet (100m) with a 9mm pistol and up to 565 feet (200m) away with a 5.56mm rifle.

K6 12.7mm Heavy Machine Gun

The tank commander’s 12.7mm K6 HMG (S&T Motiv) has a blank firing attachment.

 

This Korean-made .50-inch (12.7mm) heavy machine gun was one of the competitors for a Norwegian acquisition of new 12.7mm HMGs. It’s a closed-bolt design; short-recoil barrel operation, fixed headspace, and timing eliminates safety concerns associated with barrel changing and improper timing. The weapon can be fitted to all types of armored, light and heavy vehicles, naval crafts, helicopters and other aircraft. The weapon fires all types of NATO ammunition: ball, tracer, AP, API, APIT, AP hardcore and multipurpose, sustained automatic or single-shot accuracy. The quick changeable barrel (QCB) allows the barrel to be quickly exchanged by one operator.
