AAC MPW 12.5″ Short Barrel Rifle 300BLK

The Advanced Armament Corporation complete MPW rifle in 12.5” barrel, chambered for 300 AAC BLACKOUT allows for a 30 caliber rifle the size of an AR15 5.56mm caliber rifle, without a reduction in magazine capacity. The AAC MPW in 300 AAC Blackout uses ordinary 223/5.56mm magazines for a full 30 round capacity. The 1:7 twist barrel is nitrided to provide extreme corrosion resistance and high hardness for a long life – outperforming chrome-lined barrels for longevity without the potential impediments to accuracy. The muzzle is threaded 5/8-24 and includes an AAC 51-tooth BLACKOUT flash suppressor with the complete upper. A Knight’s Armament free-floating URX III helps maintain accuracy while providing for the mounting of accessories.

The bolt carrier group’s nickel boron (Ni-B) UCT EXO coating has a very high hardness and lower friction than either chrome or nickel teflon. There is a base layer of high-phosphorus electroless nickel that ensures extreme corrosion protection that is absent from other Nickel Boron carriers that use a single, thinner layer. The bolt is Carpenter 158 phosphated shot-peened steel to ensure precise dimensions with no concerns for hydrogen embrittlement in the critical lug area. A special green o-ring tested to not bind at -40 degrees F is standard. The extractor spring is made from premium ultra-strong wire and is a low fatigue design to ensure the longest possible life. The extractor pin is made from 300 ksi S2 tool steel – not the lesser strength S7, more commonly used. Finally, a properly-staked carrier-key with Permatex gasket-seal compound ensures no gas leakage. The trigger is from Geissele for great feel and reliability, and the stock and pistol grip is by MagPul Industries. One magazine is included. Optics, mounts, and suppressors are not included. The recommended optional sound suppressor is the AAC 762-SDN-6, which provides an average of 39.3 dB reduction with subsonic ammunition.
