Faxon Firearms FF308BCNITRIDE 9310 AR-10 Bolt 308/6.5 Creedmoor - Black Nitride

The Faxon Firearms FF308BCNITRIDE is a precision-machined AR-10/.308 bolt assembly built from 9310 tool steel and finished in Black Nitride for increased surface hardness, corrosion resistance, and lower friction during cycling.

Engineered as a direct-fit replacement for the AR-10 platform, this full-auto rated bolt is compatible with .308 Winchester, 6.5 Creedmoor, and 8.6 Blackout. It is DPMS Gen 1 pattern compatible, making it a versatile upgrade for a wide range of .308-pattern rifles.

Key features include a .125" firing pin, an S7 tool steel extractor for reliable extraction under sustained fire, and chamfered bolt lugs for smooth, consistent lockup. Each bolt is MPI (Magnetic Particle Inspected) tested to verify it is free of cracks and material defects before it leaves the factory.

Whether you are building a precision 6.5 Creedmoor rig, a hard-recoiling .308, or a heavy-hitting 8.6 BLK platform, the Faxon 9310 bolt delivers the strength, durability, and consistency expected from a premium aftermarket component.
