KAK Industry K-SPEC Enhanced Bolt Carrier Group Features The KAK Industry K-SPEC Enhanced Bolt Carrier Group is machined to the M16 full auto carrier profile and built around a 9310 steel bolt for strength under repeated cycling. A hard chrome finish on the bolt and carrier resists corrosion and wear while easing cleaning after heavy use. The dual ejector system improves case extraction reliability reducing the chance of a stuck or failed-to-eject case during rapid fire. Side vent cuts in the carrier help manage gas and debris keeping the action running smoothly in dirty or suppressed conditions. Slotted angled carrier rails are designed to channel grit and fouling away from critical wear surfaces extending reliable function between cleanings. This makes the K-SPEC Enhanced a strong choice for both 5.56 NATO and .300 Blackout rifles including suppressed builds that generate extra carbon buildup. At 11.50 oz the bolt carrier group adds the mass needed for consistent cycling without unnecessary bulk. The KAK Industry K-SPEC Enhanced Bolt Carrier Group is available for sale at GrabAGun for AR-15 owners who want a drop-in upgrade built for reliability in any environment.
