Complete .300 AAC BLACKOUT Upper Receiver Assembly. Ready to drop onto your AR15/M16/M4 lower! Works with an AR lower with "Mil-Spec" push pin locations.
Advanced Armament Corp. AR-15 Upper Receiver Assembly in .300 AAC Blackout is a pin-on, ready-to-shoot top end for use with any legally registered SBR or dedicated pistol AR-15 lower receiver. The Mil-Spec 4150 chrome moly vanadium steel barrel comes equipped with 1 in 7" twist rifling, M4 feed ramps, a low profile steel gas block, and is finished inside and out with a protective black nitride treatment for superior durability and corrosion resistance. The muzzle is threaded with a 5/8"-24 pitch for easy installation of a silencer, and is topped off with an effective AAC 51T Blackout flash hider.
The upper features a forged M4-style flat-top receiver onto which a Knight's Armament free floating URX III Modular Rail System is rigidly attached. The URX III creates a full length top rail surface when matched with the flat-top upper to accommodate almost any desired sighting arrangement. This customizable handguard allows shooters to attach modular rail sections along its length only where needed for adding accessories, keeping the remainder of the handguard slim, smooth, and snag-free. The heat-treated, full auto bolt carrier is finished in a slick Nickel Boron coating, and comes equipped with a properly-staked gas key and Carpenter 158 steel bolt assembly.
This 9" 300 Blackout upper utilizes a pistol length gas system and is compatible with most subsonic and supersonic ammunition, with or without a sound suppressor in place.
