Bolt carrier groups are available aplenty, but few could meet Faxon®'s exacting standards for performance and value. Seeing "MIL-SPEC" as just the starting point, Faxon set out to provide a better option for demanding end users.

Improvements include using 9310 tool steel for the bolt, which is significantly stronger than most bolt materials. Additionally, the assembly has been nitrided to increase surface hardness, decrease friction resistance, and provide superior corrosion compared to standard chrome and phosphated finishes.

All bolts are fully MPI-tested to ensure the material is sound and without defects. Bolt lugs are chamfered 45° to ensure reliable action for even the highest pressure hand loads and fast lightweight actions. Faxon Bolt Carrier Groups are superfinished to reduce friction, increase smoothness of operation, and reduce fouling. Further, they are full-auto rated and maintain the trip for full-auto fire control groups and new multi-stage trigger systems. Gas keys use grade 8 fasteners and are fully staked for a lifetime of service.
