Bishop Ammunition Manufacturing's AR-15 Billet Lower Receiver 80% 7075 billet aluminum used to build our stripped lower receivers and our competition rifles.  CNC machined. This firing pin is made out of titanium not steel. This titanium AR-15 firing pin is 40% lighter than a steel firing pin. A titanium pin travels faster in the bolt. The AR-15 titanium firing pin delivers a much faster lock time thereby enhancing the AR-15 accuracy. The Bishop AR-15 titanium pin has much less momentum than a steel AR-15 firing pin. This reduces the chance of a dangerous slam-fire. AR-15 titanium firing pins will not rust, corrode, and they withstand high temperatures. The Bishop AR-15 titanium firing pin eliminates galling, fretting, and seizing in the bolt carrier group. These pins are polished and meet MIL-T-9047 and MIL-H-81200 for material and heat treatment specs. AR-15 Forged Lower Receiver, Bishop Ammunition Manufacturing's stripped lower receiver used on our competition rifles.  Forged T6 aluminum, CNC machined.
