Description
This KAK Industry AR-15 bolt carrier group is the DBC (dead-blow carrier) chrome-lined phosphate model for 5.56 NATO and .300 Blackout, manufacturer part number MO-425-0510-043. It is a right-hand, side-vent BCG without K-SPEC rail cuts or a dual-ejector bolt. A floating weight in the carrier tail gives a dead-blow effect to reduce bolt bounce, and the complete group weighs 14.5 oz.
The M16 auto-profile carrier is aircraft/bearing-quality 8620 steel, chrome-lined phosphate. The bolt is a single piece of 9310 steel, heat treated, precision ground, shot peened, and MPI inspected, with a phosphate finish. The extractor is a one-piece billet fully machined extractor with a phosphate coating.
The DBC weight lets you run a standard 3 oz carbine buffer instead of H buffer weights with a forced-reset trigger, while still giving the trigger enough carrier mass to function as intended. It has been factory tested with the Hoffman Tactical Super Safety, AS Designs ARC fire FRS, Atrius Development FRS, and Rare Breed FRT. Similar designs should work as well.
