KAK Industry K-SPEC Enhanced M16 5.56 NATO/.300 Blackout Clear Anodize BCG

The KAK Industry K-SPEC Enhanced M16-profile Bolt Carrier Group is built for AR-15 and M16 platforms chambered in 5.56 NATO and fully compatible with .300 Blackout. This drop-in BCG uses a 7075 aluminum carrier finished in clear anodize (silver) for corrosion resistance, paired with an NP3-coated 9310 steel bolt and NP3-coated cam pin for smooth, reliable cycling.

The K-SPEC Enhanced design adds dual ejectors and downward-facing gas ports (down vent) to route excess gases away from the shooter's face and improve reliability across a range of gas system lengths. Intended for use with mid length, rifle length, or similar gas systems, this complete bolt carrier group ships ready to install in your upper receiver.
