AAC MPW 12.5" 300 Blackout SBR. This 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.

This AAC MPW rifle is manufactured with premium components.  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 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 no bind even at  -40 degrees F is standard.  The extractor spring is made from premium ultra strong wire and is low fatigue design to ensure the longest possible life. The extractor pin made from 300 ksi S2 tool Steel. 

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 by Magpul Industries
