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, and is available in 12.5, and 16 inch barrels.*
Components are of premium quality. 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 also a base layer of high-phosphorous electroless nickel that ensures the extreme corrosion protection that is absent from other Nickel Boron carriers that use a single, thinner layer. 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 – not the much lower strength S7 more commonly used.
