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″ M-LOK Rail that contains generously sized M-LOK cuts, this upper assembly allows for maximum air circulation around the barrel for faster cooling and keeps the handguard from getting hot to the touch. 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 partial 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.

Firstly, I’m a huge fan of CBC Industries – I originally purchased a 7.62×39 FDE Pistol, from then on I was hooked. For the 16″ 5.56 upper assembly, it’s a bargain the Mlok rail is very sturdy and locks up tight to my mil-spec lower. Couldn’t be more happy with it!
