Description
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 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.
Outfitted with a 15″ Keymod Rail that features strong attachment points for accessories resulting in accessories and optics having an excellent return to zero capability when detached and reattached. The rail also features a full-length picatinny top rail that sits flush with the upper receiver and has anti-rotation tabs to keep it locked in place. 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.

This was the second upper I have ordered from CBC and they made me a loyal customer with this one! When my upper came in in the amount of time they stated (3weeks at the time) I found a slight issue with my barrel nut, when I called them there was no delay in shipping me a replacement immediately. this mid length upper is one of the smoothest cycling I’ve ever shot, and WOW at the accuracy! With 75gn hornady I shot 3 groups of 5 @ 100 yds and all were under an inch! I’ll take that! Thanks CBC! Your uppers and customer service are top notch!
