  1. Rated 5 out of 5


    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!
