The Dirty Bird Industries Nickel Boron Bolt Carrier Group is a substantial upgrade from a standard BGC. Its NiB coating reduces friction on sliding surfaces and prevents carbon build-up making cleaning a much easier task. The NiB coating offers great heat dissipation, allowing reduced wear on the BCG and interacting parts, to further prolong the lifespan of the unit. MIL-SPEC dimensions ensure correct component function and reliability.
