Dark Matter^™ High-Polish Black DLC Bolt Carrier Group (5.56mm / .300 BLK)

Introducing the Dark Matter^™ bolt carrier group, where form meets function. Cloaked in a mirror-like polished DLC (diamond like carbon) coating, the Dark Matter BCG has a glass-smooth finish made to dramatically reduce friction, offer superior lubricity, and make cleaning especially easy. The bolt itself is MPI (Magnetic Particle Inspected). For added long-term reliability, our gas keys are staked using OCKS screws (Optimized Carrier Key Screw) which feature sharp, deep, effective knurling to ensure superior staking.
