Faxon Firearms Type 2 6.5 Grendel AR-15 Bolt - 9310 Steel - Salt Bath Nitride

The Faxon Firearms Type 2 AR-15 bolt is purpose-built for the 6.5 Grendel cartridge and engineered as a premium drop-in replacement for shooters building or upgrading a Grendel-chambered AR-15. Machined from 9310 tool steel and finished in Salt Bath Nitride for a hard, corrosion-resistant surface, this bolt carries the durability needed for high-stress, high-pressure service.

The Type 2 bolt face features a .136" co-bore and is cut to SAAMI-spec dimensions, making it fully compatible with 6.5 Grendel, 6mm ARC, 22 ARC, and 338 ARC chamberings. This multi-caliber versatility lets a single bolt serve a range of modern AR-15 cartridges, whether you're stepping up from 5.56 to Grendel or running a 6mm ARC setup.

Faxon builds this bolt to full MIL-SPEC heat treatment standards, then shot-peens the assembly to MIL-SPEC and runs it through magnetic particle inspection to catch any subsurface flaws before it ships. The result is a thoroughly vetted replacement bolt designed for reliable cycling and long service life in a hard-use AR-15.

Designed to drop into standard AR-15 bolt carrier groups, this bolt is an ideal choice for custom Grendel builds, chase-barrel conversions, and anyone seeking a tougher, more rigorously inspected component than typical commodity offerings.
