KAK Industry M16 5.56 NATO BCG - Phosphate Chrome Lined

The KAK Industry M16 5.56 NATO Bolt Carrier Group is a drop-in BCG built around an M16 auto-profile carrier, offering a reliable upgrade for any AR-15 build chambered in 5.56 NATO or 300 Blackout.

Constructed from 9310 steel, the carrier is chrome lined for bore and gas-port durability and finished in a wear-resistant black phosphate coating that stands up to hard use and routine cleaning. The M16 profile adds mass along the bottom of the carrier for increased weight and stability during cycling, and is a popular choice for AR-15 builds seeking extra carrier heft.

Designed as a direct drop-in for any standard AR-15 upper receiver, this BCG delivers dependable cycling with both 5.56 NATO and 300 Blackout loads and ships ready to install as a complete carrier assembly.
