KAK Industry DBC K-SPEC AR-15 5.56/.223/300BLK Bolt Carrier Group – Phosphate/Chrome-Lined
The KAK Industry DBC K-SPEC Bolt Carrier Group combines a dead-blow carrier design with KAK’s enhanced K-SPEC features for reliable AR-15 operation in both suppressed and unsuppressed setups. A floating weight in the carrier tail helps eliminate bolt bounce and adds the mass needed for compatible forced-reset systems while allowing use of a standard 3 oz carbine buffer. Downward gas vents redirect blowback away from the shooter, dual ejectors improve ejection consistency, and angled carrier rails help move fouling and debris away from critical contact surfaces. The chrome-lined phosphate finish adds proven wear and corrosion resistance for hard-use builds.
