Product Description

This drop-in A3 upper will mount to virtually any standard AR-15 mil-spec lower receiver. Though not a long distance cartridge, accuracy has proved to be exceptional out to 200 yards with felt recoil similar to a 20 gauge shotgun. The tubular aluminum forend allows the barrel to free float from the nut forward, and chrome lining in both bore and chamber makes for long barrel life and easy cleaning. This upper receiver assembly comes complete with a charging handle, forward assist, ejection port cover, bolt and bolt carrier assembly. The upper also features a versatile flat top for mounting optical devices or accessories. Includes a 5 round magazine. Installation of AR-15 upper assemblies with certain features including, but not limited to: flash hiders, bayonet lugs, and threaded muzzles may violate state and/or local laws.
