We don’t just machine out the bolt face on a standard 5.56mm bolt leaving a thin wall and weak lugs. We machine it right from the start and you use your STANDARD AR15 firing pin. . As with all of our bolts we finish grind all critical diameters “After” heat treat resulting in a bolt that is true and square to the bolt face for 100% lug contact. Available in 7.62 x 39 Other calibers coming soon.
Made from 9310 steel and heat treated to mil spec.
