    I ordered this 300 blk upper assembly last summer from Cbc and have been very pleased with it. It is lightweight but doesn’t feel cheap either I have shot about 150 rounds with this with no problems.

    This was my first AR build, I choose CBC because of the good things I read online on different gun forums, I also liked the fact that you make your own barrels. I definitely made the right decision, I was very impressed with the quality and craftsmanship. I had no problems with assembly on my lower and although I have not put more than 100 rounds through my AR I have had zero problems and the accuracy is great. I plan on doing another AR (or more) and I know I will buy my other uppers from CBC, for the value there is no reason to shop anywhere else. Thanks CBC for the fast shipping and quality product.
    P.S. I am also very pleased with the HERA key mod handguard.

    Bought this upper in February 2016 from Sportsmans guide it was love at first sight. This upper will shoot sub MOA at 100 yds. on a rest. For the people that find it hard to find 300aac amo go to Wally Mart Remington brand $16.44 per box. Back to quality ,value, workmanship thank you CBC for Vet workers. Ordered model 160-380 this past Monday for Value, and Quality and Promo. Thanks CBC

    The upper was received in about 4 weeks after order date, wrong tracking information was sent by email. It was not shipped by DHL but FedEx was the correct carrier. The upper was received in good condition except the flash hider was upside down. All in all the upper is a good upper for the price. Thanks for your help Lorraine, with my first purchase from CBC.
