16" Chrome-Lined Barrel
Free-Floating URX III Forend
MagPul Stock/Pistol Grip
The MPW is a well-built tactical rifle from Advanced Armament Corp constructed of premium quality components and a high-capacity 30-round magazine. 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. A Knight's Armament free-floating URX III forend helps maintain accuracy while providing for the mounting of accessories. The bolt carrier group's nickel boron UCT EXO coating has a very high hardness and lower friction than either chrome or nickel Teflon. The bolt itself 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 that is tested to not bind even 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 made from 300 ksi S2 tool steel rather than the much lower strength S7 more commonly used. Finally, a properly-staked carrier-key with Permatex gasket-seal compound ensures no gas leakage. The trigger is a Geissele for great feel and reliability. The stock and pistol grip are made by Magpul Industries.
