KAK Industry M16 AR-15 BCG 5.56 NATO Phosphate & Chrome Lined Bolt Carrier Group

Upgrade your AR-15 with the KAK Industry M16-profile Bolt Carrier Group, purpose-built for reliable performance in 5.56 NATO chambered rifles. Machined from Carpenter 158 steel and finished with a military-spec phosphate coating over a chrome-lined interior, this BCG is engineered to withstand the rigors of high-volume shooting, harsh environments, and everyday carry alike.

The phosphate (parkerized) exterior provides a durable, corrosion-resistant first layer of defense, while the chrome lining inside the bolt carrier and bolt enhances wear resistance, eases cleaning, and ensures consistent function round after round. The M16-profile carrier provides full auto compatibility and improved cycling reliability, making it a smart choice for both semi-automatic AR-15 builds and competitive shooting setups.
