Don’t pay for a logo, pay for quality.

Contracted for us by an ISO 9001 certified company for manufacturing and design. Over 50+ years of experience and 100% made in the U.S.A. They make BCG’s for MANY of the top names in the industry, but they do not sell anything to the public. They are the best firearms company you never heard of. Satisfaction guaranteed. WE DO NOT CHANGE OUR CONTRACT SHOP FOR BCG’s! Too many places purchase BCG’s from multiple sources depending on price, availability, etc. We have used the same contract shop for years and do not compromise on that. Simply put, the bolt carrier group is just too important of a part to take chances on quality. We just don’t have problems with our bolt carrier groups…ever.

    All I care about is reliability. The nitride feature was a plus, but I just need a bolt carrier group that will run. After 14000 + rounds through my gun, I have had zero malfunctions of any sort. Not sure if I needed to, but I replace my extractor spring and insert after every 3000 rounds, but that’s just me. Took a chance on this bolt carrier group and am extremely happy that I did. Overall fit and finish was perfect with minimal to no tool marks. Would definitely buy again.

    Came across this product on a search and decided to take a chance. Never heard of these guys before, but being a Vet, I like to support veteran owned businesses. The finish rivals any BCG I’ve seen, and I’ve shot quote a bit. Ran it through 4 carbine courses so far with zero issues related to the BCG whatsoever. Bought lots of stuff from them since and have been happy with everything.
