Faxon Firearms Type 1 7.62x39mm 9310 Steel AR-10 Bolt - Salt Bath Nitride

The Faxon Firearms Type 1 Complete Bolt is a premium replacement and upgrade bolt purpose-built for AR-10 platform rifles chambered in 7.62x39mm. Designed for builders and armorers working with mil-spec and aftermarket AR-10 components, this bolt delivers reliable cycling and long service life in the popular 7.62x39mm chambering.

Faxon machines the bolt from 9310 steel, a high-strength alloy valued for its excellent fatigue resistance and impact toughness. The component is then finished in salt bath nitride, a surface treatment that hardens the exterior, reduces friction, and provides excellent corrosion and wear resistance - well-suited to the demands of repeated 7.62x39mm firing.

The Type 1 designation identifies the bolt face geometry, which uses a .125 face engineered to properly headspace 7.62x39mm cartridges. It serves as a direct-fit replacement for compatible AR-10 bolt assemblies and pairs naturally with Faxon Firearms barrels and other quality AR-10 components. Whether you are completing a 7.62x39mm build, replacing a worn factory bolt, or upgrading for improved durability, this Faxon bolt delivers the strength and finish quality expected from a premium component.
