Brand New in the Box, Ready to Ship. Buy It Now!!

This 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 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 KAC URX rail is rigidly attached. The URX creates a full length top rail surface when matched with the flat-top upper to accommodate almost any desired sighting arrangement. 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 12.5" 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.
