KAK Industry M16 224 Valkyrie/6.8 SPC BCG - Phosphate Chrome Lined

The KAK Industry M16 224 Valkyrie/6.8 SPC Bolt Carrier Group is purpose-built for AR-15 platforms chambered in 224 Valkyrie or 6.8 SPC, two of the most popular intermediate cartridges for long-range AR-15 performance. The M16 (full-auto) profile carrier is precision-machined, properly heat-treated, and ground to exact tolerances for reliable cycling in either caliber.

Constructed from 9310 steel, this BCG features a chrome-lined bore and key for easier cleaning and extended service life, finished in a corrosion-resistant black phosphate coating. The full-auto profile includes the third, forward-positioned auto-sear lug, making this carrier compatible with both semi-automatic rifles and registered select-fire builds.

Whether you are building a 224 Valkyrie rig for long-range precision shooting or chambering a hard-hitting 6.8 SPC for hunting and duty use, this drop-in BCG delivers a single, dependable component for either conversion. Manufacturer part number: MO-425-0512-019.
