CBC AR15 Upper Assembly
This AR15 upper receiver assembly comes ready to attach to any Mil-Spec lower receiver. It is built around a 7.5 inch, 4150 chrome moly barrel and has a black phosphate 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.
This upper assembly 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.
