Works perfectly. Fast shipping. Couldn't be happier.
BCM mil-spec is far superior over your average mil-spec parts. Customer service even guided me to choose the correct weight for my 12.5 build. It’s the best shooting carbine I now own. I’ll be upgrading the rest of my SBRs with this kit!
Flawless!!!
Excellent quality as always. Repeat purchase of this product. Won’t be the last.

Great well made product
Your product are always of the best quality. That it why I keep returning to you when I am in need of anything. Keep up your good work. Best of luck in the future political climate. God bless America
Outstanding quality. Very well made product.
I only bought this kit because my AR-15 had a "commercial" buffer tube and I could not find a stock I want that fit. This is a quality piece that will work with Mil-Spec Stocks. I have only shot about 250 rounds on it and to be honest I don't notice a difference using this tube, buffer, and spring.
