Faxon Firearms 308 6.5 Creedmoor Nitride Steel Full Auto Bolt Carrier Group

The Faxon Firearms FF308BCNITRIDE delivers a robust Black Nitride steel bolt carrier group designed for precision, reliability, and durability across 308 and 6.5 Creedmoor platforms. Built with a 9310 tool steel bolt, the assembly is nitrided to increase surface hardness, reduce resistance, and provide superior corrosion resistance compared with typical chrome and phosphated bolt carriers, ensuring long-term performance in demanding conditions. Every bolt is fully MPI tested to confirm material soundness and defect-free construction, while the bolt lugs are chamfered at 45 degrees to promote smooth, reliable action even with high-pressure hand loads and fast, lightweight cycling. The extractor is crafted from S7 tool steel and is engineered to be sprung via a precise combination of spring, O-ring, and silicone insert, delivering consistent extraction and timing. Finished in a durable Black Nitride, this bolt carrier group emphasizes strength, corrosion resistance, and dependable operation for rifle builds that demand rugged performance. Ideal for shooters seeking a hard-wearing, scientifically engineered BCG that supports reliable cycling, smoother action, and extended service life in high-stress shooting scenarios.
