    I put 850 rounds through this upper in approximately an hour and a half. There was zero issues and zero stoppages. It still maintained 1 MOA throughout the process. I highly recommend this to anyone looking for a good deal on an excellent upper receiver.

    I stopped by the CBC facility in Charleston one afternoon and told George, the production manager, what I wanted. He collected the parts while I was there. I ordered it on the website that evening and George had it ready for pick-up THE NEXT MORNING! When he brought it out, all I could say was BEAUTIFUL!
    The SS fluted barrel and HERA Arms key mod rail are a beautiful, high quality combination.

    I am already planning for a 300 Blackout pistol length upper.

    Thanks CBC!

    I ordered this complete upper to finish out my Anderson lower build. I was simply amazed at the quality of this upper. I know looks aren’t everything, but this stainless fluted barrel with the nickle boron just looks awesome. Great shooter at 1moa. I got this back in July and decided to wait for the review. I have put it through it’s paces and has performed well. Thanks CBC for the great quality…. fast shipping as well! I will definitely be buying from CBC again!!

    The best customer service I’ve seen in a long time. There was a problem but CBC quickly fixed it. No worries when buying from CBC, they stand behind their products. I will most definately buy from CBC again soon!
