Matched Set Provides Smooth, Reliable Cycling
Steel bolt and bolt carrier combos are available in three ultra-hard, wear-resistant, self-lubricating finishes. Choose from hard Chrome plating, Titanium Nitride (TiN) coating, or IonBond Diamond Coat for natural lubricity, positive cycling, and easy cleaning. Economical yet durable Diamond Coat consists of an ion-thick layer of carbon deposited on the bolt, carrier, gas key firing pin and cam pin for increased hardness and wear resistance over a traditional phosphate finish. Machined to military specs to ensure correct fit and operation in standard, mil-spec semi-auto receivers, these parts are function-tested before leaving the factory and may exhibit some light fouling.
