CMMG Bolt Assembly AR-15 – Replacement Bolt Carrier Group Component

The CMMG Bolt Assembly for AR-15 platforms is a precision-machined replacement component for worn or damaged bolt assemblies in standard AR-15 bolt carrier groups. This assembly includes the bolt body, extractor, ejector, and associated small parts, allowing shooters to rebuild a carrier group without replacing the entire BCG. It's designed for shooters who need to replace a bolt that's reached the end of its service life or has suffered a failure.

Manufactured from mil-spec 8620 steel with a manganese phosphate finish, this bolt assembly is properly staked and heat-treated to MIL-B-11595 standards. Installation requires basic armorer knowledge and punch set for disassembly and reassembly of the bolt carrier group. This is a complete bolt assembly ready to install into your existing carrier.
