Carrier made with 8620 Steel and bolt made from 9310 Vac-Arc Premium Carburizing Steel which has a high core hardness and high fatigue strength unlike standard Hot/cold rolled 9310 steels. The nitride coating is the strongest plate available, it's the same protective finish that's used in gun barrels and CNC tool protection. If you're looking for a bolt carrier that's going to hold up against the roughest conditions, then this bolt carrier group is the one for you.
