Daniel Defense Bolt Carrier Group BCG Complete 5.56mm NATO
Daniel Defense Complete Bolt Carrier Group Assembly, Black - Reliable Performance - 04-013-19032
Daniel Defense manufactures this complete 5.56mm bolt carrier group to the same standards as the BCGs installed in its complete rifles. The 8620 steel carrier and Carpenter 158 steel bolt assembly receive a heavy phosphate coating, with chrome lining in the carrier and gas key for durability and easier cleanup.
The bolt is shot peened, high-pressure tested, and magnetic-particle inspected. The extractor booster supports reliable extraction across 5.56/.223 and .300 Blackout builds, and the gas key is properly staked for hard-use reliability.
The M16 full-auto-compatible profile gives the carrier enough mass for reliable cycling in suppressed or short-barreled configurations. This is the premium DD-pattern BCG pick for builders who want the same core carrier group used across Daniel Defense rifle builds.
Add the Daniel Defense M16 Bolt Carrier Group to your build and see how it enhances your platform.
