The Faxon Firearms Type 1 Bolt in 7.62×39 (brand part number FF76239GBCNITRIDE) is machined from 9310 steel, a step up from standard 8620 steel for strength and fatigue resistance under repeated cycling. Faxon finishes it with a salt bath nitride treatment, which hardens the surface for wear resistance while adding corrosion protection beyond a standard phosphate finish. It’s built for AR-15-pattern rifles running the 7.62×39 cartridge, giving you a durable direct replacement bolt without needing a full bolt carrier group swap.
