This AR15 upper receiver assembly comes ready to attach to any Mil-Spec lower receiver. It is built around a 16 inch, 4150 chrome moly barrel that is chambered in 5.56 NATO and has a black nitride finish. 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.
Comes with a standard A2 flash hider that effectively suppresses muzzle flash and protects the 1/2×28 barrel threads if you are planning on adding a muzzle break in the future.
