The Faxon Firearms .308/6.5 Creedmoor Bolt (brand part number FF308BCNITRIDE) is machined from 9310 tool steel and nitrided for higher surface hardness, lower friction, and corrosion resistance that outperforms typical chrome or phosphated bolt carrier groups. Every bolt is fully MPI tested to confirm the material is sound and free of defects before it ships. Faxon chamfers the bolt lugs 45 degrees for reliable lockup under the highest-pressure hand loads and fast, lightweight actions, and pairs the bolt with an S7 tool steel extractor sprung by a spring, o-ring, and silicone insert for redundant, reliable extraction.
