It is nice to see a product evolve over time. The ArmaLite AR-31 .308 Win rifle is a great case in point. The AR-31 shares its design lineage

with previous ArmaLite precision rifles in the form of the AR-30 and its updated version AR-30A1. The AR-30A1 rifle is chambered in “long

action” bolt cartridges such as .300 WinMag and .338 Lapua. The AR-31 takes the no nonsense ArmaLite concept of the tactical rifle another

step forward. While the AR-31 (and AR-30A1) may resemble its AR-30 predecessor, only the pistol grip, buttpad, trigger, and a few small

components from the original AR-30 transferred over to the AR-31. All other components are new or redesigned. This is especially true with

the AR-31’s bolt action. The AR-31’s “short action” describes the length the bolt needs to travel to function/cycle the .308Win cartridge.

The longer .300 WinMag and .338 Lapua cartridges require a “long action.” The AR-31’s shorter action provides for a stiffer receiver often

translating into better accuracy.
