Precision Defense™ 5.56 Complete M16 Bolt Carrier Group - Nitride

The Precision Defense™ 5.56 M16 Complete Bolt Carrier Group is machined from high-quality materials to ensure your AR-15 will run reliably as long as you have ammo to shoot it with. The carrier body is machined from 8620 steel and finished in black Nitride for its slick and durable qualities making it run extremely smooth in your receiver. It features an M16 cut allowing it to be full auto rated and the extra weight helps to reduce bolt bounce. The bolt is machined from 9310 steel and magnetic particle inspected to ensure all the dimensions are properly cut to allow for reliable lockup on the locking lugs. The extractor is made from S7 tool steel to withstand thousands of rounds and the gas key is machined from a stock of billet steel with properly staked screws. The Precision Defense 5.56 Bolt Carrier Group is an affordable and reliable option for building an AR whether it is your first or tenth.
