    Shipping was great. The upper was exactly how it was described. As soon as I opened the box I was extremely pleased with the quality and craftsmanship. It hugs tightly to my lower. I really love the looks of this upper. It’s actually my favorite so far. (I own 9 other AR’s) I will be purchasing the golf ball upper in the next couple days that is on special. No burs, scratches or flaws in the upper. I will take it to the range in the next couple days…I mounted a Vortex Sparc II to it so I’m sure it will shoot flawlessly. Thank you CBC Industries for a great product & TU to the veterans that are putting them together!

    Great value. Not one single complaint. The customer service is some of the best in the business. I will buy others . As a vetren myself I can’t help but to like the people CBC hires. Of course the fact they produce a top quality product doesn’t hurt either. Thanks and keep up the great job!

    i stumbled upon this web site, and I’m glad I did. I was looking for some affordable, good quality products for my latest build. After reading nearly every review, I decided to give CBC a try. Being a veteran myself, I appreciate the craftsmanship is done by vets. I will let my friends know, and I will be ordering again. By the way, this thing fits my PSA lower perfectly. Five Stars From Me!
