KAK Industry K-SPEC Enhanced M16 5.56 NATO/.300 Blackout BCG - Chrome, Dual Ejector, Side Vent

The KAK Industry K-SPEC Enhanced M16 Bolt Carrier Group is a premium drop-in BCG engineered to run reliably across both 5.56 NATO and .300 Blackout platforms. Machined from a heat-treated 8620 steel carrier and paired with a 9310 steel bolt, this M16-pattern unit is finished in chrome for corrosion resistance and easy cleaning, and is configured with KAK's signature dual ejector and a side-vent gas porting pattern for clean, positive ejection whether you run suppressed or unsuppressed.

The K-SPEC Enhanced design is a true plug-and-play BCG suitable for any standard AR-15/M16-pattern rifle or pistol. Dual ejectors help ensure positive extraction when running subsonic .300 Blackout, supersonic loads, or standard-pressure 5.56, while the angled side-vent cuts bleed gas forward and out instead of venting straight down. This is the Chrome side-vent variant (KAK p/n MO-425-0505-003), intended as a direct upgrade or replacement BCG for your build.
