Quite frankly the best BCG on the market. Many of the big names use these and sell them at a much higher price point. We’re so confident in these that we are offering a lifetime warranty on these BCG’S. Unheard of for a BCG, but that’s how confident we are in these.

These exact same BCG’s are sold by other ‘big name’ shops for much more.

Contracted for us by, an ISO 9001 certified company for manufacturing and design located in Naples FL. 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. They don’t sell to the public, so 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.

The *Enhanced* carrier is designed to reduce tilt/cant during recoil and increasing reliability by strategically relocating key bearing surfaces. The Enhanced carrier has fewer points of contact resulting in less friction area and the slight increase in carrier mass extends dwell time and ensures proper gas pressures for reliable extraction.

    I’ve bought these for almost double before stumbling onto this site. There’s not that many actual manufacturers of BCG’s, so it’s easy to spot who made what if you know what to look for. The finish is excellent and they function 100%

    Having a battle arms development BCG already for one of my precision builds I knew what I was buying . Beautifully machined and finish. It’s every detail as described . I’ don’t need a logo . I need a top quality BCG with a life time guarantee!!! Can’t ask for more . Received in 2 days from purchase .
