  1. Rated 5 out of 5


    This was my first rifle kit purchase from CBC and I m greatly satisfied with the fit and finish of this upper. CBC upper matched perfectly with my stag lower. I haven’t been able to take it out to the range yet and test it out. Would deff recommend their products to other people and will definitely be buying more items from CBC. Shipping was on point with their posted lead time and constant updates while in transit. All around happy with my purchase.

    This is the first rifle kit purchased from CBC. Deff worth the money and greatly satisfied with the fit and finish. No marks or blemishes and matched up perfect with my stag lower. Haven’t been able to get out and test fire it. Would recommend it to anybody looking for a quality rifle kit for a really good price. Will definitely be ordering more rifle kits and or any products from CBC. Shipping was on point with posted lead time and was updated constantly with shipping statuses.

    2 1/2 weeks from order to delivery, very acceptable for the current political firearms climate. Received my kit 3 days ago, sent projectiles down range today, very impressed with fit/finish and performance….shoots nicer than a pre-assembled namebrand AR that I own. Communication was great and timely. Highly impressed with the keymod handgaurd ,is nicer than expected and the butt stock is a very nice upgrade from what is pictured(was not charged extra!) After placing my order,I looked at company reviews( I know,research first-then order), was nervous. Well, I’m glad I ordered from CBC, very nice product and experience thus far! I will not hesitate to give my business and refer friends to CBC in the future! Thank you very much for a product that exceeds my expectations!!!!
