LMT M16 / AR-15 Bolt Carrier Group 5.56/.223

The Lewis Machine and Tool AR-15 bolt carrier group is a full auto rated, M16 cut BCG designed for long term durability and reliability. The manganese phosphate carrier is machined out of 8620 Carpenter steel and has been magnetic particle inspect to ensure the dimensions are Mil-Spec or greater. The bolt is machined from 158 Carpenter steel and also features the extremely durable Manganese Phosphate finish. The bolt has also been high pressure tested to ensure that it has been properly hardened without being brittle. The gas key has been properly staked to prevent the hardened screws from backing out over time and the heavier weight of the M16 profile helps to prevent bolt bounce during rapid fire.
