AAC MPW URX III Rail 300 Blackout, 16" Barrel, MagPul CTR Stock 30 Rd Mag - $929.99

Description

A Knights Armament free-floating forearm rail maintains accuracy and provides plenty of surface area to mount accessories. The bolt carrier group meets full auto specifications and the precision lower receiver is full auto pictogram marked (safety configuration does not allow for full auto use) The Carpenter 158 steel bolt is shot peened and the properly staked gas-key is heat treated for durability. The barrel has a 1:7" twist 5R. The entire barrel, including bore and chamber, has a nitride finish to resist corrosion and provide hardness for longevity, far outliving chrome-lined barrels without impeding accuracy.
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.

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, and the stock and pistol grip by MagPul Industries. One magazine is included. Optics, mounts, and silencer 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.
