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 12″ 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.

I received my upper today. It had a clue of very small scratches but I’m gonna Duracoat it anyway. Strapped it to my lower and ran a mag through it. It’s AWESOME. The fit to my Anderson lower is super tight. No play at all. I will definitely buy another in the near future.

I have looked and I still cannot find the blemish on mine. I paired it up with a Del-ton Lower and I’m using a Del-ton charging handle and PSA Nitride BCG. The fit to the lower is snug, have not had so much as a hiccup with the 240 rounds I put through it. Great accuracy as well. You cannot beat CBC’s quality for this price. Thanks again CBC!

Looked the upper over and I’m not sure where the blemish is, I paired mine with a spikes tactical lower and a CBC BCG it doesn’t seem to have any problems with running rounds down range. Great upper for the price..
