Description

This AR15 upper receiver assembly comes ready to attach to any Mil-Spec lower receiver. It is built around a 10.5 inch, 300 Blackout barrel, that is optimized for stability with a 1:7 twist rate. The upper receiver is a forged M4 flat top upper, allowing you to easily attach rifle scopes and red dot sights to the picatinny rail. Designed to handle the hardest use and abuse of tactical and competitive shooting, this upper assembly is outfitted with a quad rail.

Outfitted with a 9″ IRS Rail that features anti-turn millings that prevent turning even at the hardest use. The rail also features four full-length Picatinny attachment points and a top rail that sits flush with the upper receiver, allowing you to have more space for optics and back up iron sights. This upper assembly comes with a standard A2 flash hider that effectively suppresses muzzle flash and protects the 5/8×24 barrel threads if you are planning on adding a muzzle break in the future.
