    The folks at cbc are not only good at what they do but the best customer service I’ve had at any gun shop. This upper is accurate and feels damn good.

    I already own three Ar-15’s but I wanted to build one. After searching and skimming the internet I came across this company “CBC Industries” looked over the reviews and then compared prices. When I came across this 7.5in upper, I bought it and I must say the quality for the price is unbelievable. I also ordered their 5.56 BCG and charging handle and I love it! Fired it for the first time Monday, put close to 500 rounds through it and not a single hiccup plus the accuracy was on point! Don’t think twice, just buy it! Great upper and it fits on to any standard Mil-Spec lower!

    Like-minded AR enthusiasts are going to do a build; it’s just a matter of whom. My 7.5” upper fits perfectly onto my Mil-Spec lower. In my opinion my pistol build is better than any larger of the Named companies due to the Quality CBC puts into their product lines and the excellent Pricing CBC offers.

    If it wasn’t for CBC I would not have been able to achieve my goal on the cost to build my AR Pistol. I would like to thank everyone for their hands on approach and helping me with my needs regarding my upper. Man…I couldn’t any be happier.

    Thanks CBC

    My wife and I visited CBC personally. We found this pistol upper in stock and were impressed! It fit quite well on out pistol lower and feels great,. Haven’t gotten to the range for full testing but ran 10 rounds through it in the back yard without any problems. We will be ordering more products in the future. (The people here are truly GREAT!)

    Once again CBC made a great product for an affordable price. The picatinny rail on the pistol upper is very well made, and because it is smoothed out toward the magwell there is hardly a need to add bumper pads. Before shooting I’d highly recommend tightening all the set screws. After 60 rounds the forend began to separate from the receiver. After tightening I haven’t had a single problem. All in all, phenomenal upper.
