Premium AR-10 Bolt Carrier Group
Faxon Firearms approaches bolt carrier group design by treating MIL-SPEC as a baseline, not a ceiling. The result is a carrier that delivers measurable improvements in reliability, longevity, and performance.
Superior Materials and Construction
9310 Tool Steel Bolt: The heart of this carrier uses premium 9310 tool steel rather than standard materials, providing greater strength and durability for demanding applications.
Salt Bath Nitride Finish: The entire assembly receives salt bath nitriding, which increases surface hardness and decreases friction compared to conventional chrome or phosphate finishes. This process also delivers superior corrosion resistance, keeping your carrier protected in harsh conditions.
Quality Assurance
- All bolts undergo full Magnetic Particle Inspection (MPI) testing to verify material integrity and eliminate defects
- 45-degree chamfered bolt lugs ensure reliable feeding and extraction, even with high-pressure hand loads and lightweight actions
- Grade 8 fasteners secure the gas key with full staking for lifetime durability
- Superfinished surfaces reduce friction and fouling while enhancing smoothness of operation
