Without a mil-spec standard for the 308 platform, sourcing parts that fit properly and function reliably can be a challenge. Many manufacturers, distributors, and rifle builders can attest to what a challenge developing a 308 product line can be. One of the main sources of this difficulty has always been the 308 bolt carrier group.  Most 308 BCG's don't function reliably across different AR-style platforms or even within a single platform with parts from different manufacturers. Many of the better BCG's come with super stiff bolts that take hundreds of rounds to break in before they are dependable. As a rifle builder offering lifetime warranties and striving for a top-notch customer experience, spending time and money on breaking in a rifle is simply not appealing to us or our customers. 

Enter the new nitride 308 bolt carrier group sourced by Checkmate Rifle Company.  We have spent years in search of the right high quality BCG that works dependably from the get-go and doesn't cost a pretty penny.  Our source is an aerospace and munitions US government contractor with extensive quality control who manufactures a top notch product.  Our long-standing relationship with this company brings our customers a previously unrealized marriage between quality and price for a top-notch 308 bolt carrier that requires zero break-in and will last a lifetime.

Proudly made in the USA with a lifetime warranty.
