K-SPEC M16 BCG .224 Valkyrie/6.8 SPC

K-SPEC: Mil-Spec, Enhanced.

KAK Industry’s signature design for unrivaled performance and unparalleled reliability, all K-SPEC Enhanced BCGs retain mil-spec dimensions with added Slotted Angle Carrier Rails (“sand cutters”) and Dual Ejector system.

This .224 Valkyrie / 6.8 SPC model features KAK Industry’s proprietary Down Vent configuration, venting gas downward instead of out at the shooter’s face. This redirected gas system means a quieter, less gassy shooting experience.

All KAK Industry BCGs feature a M16 (Full Auto) carrier profile, meticulously machined from 8620 steel, properly heat treated and ground to exact tolerances.

Other components include:

• Single piece billet-machined 4140 extractor, phosphate coated for increased reliability and corrosion resistance.
• 4340 phosphate coated cam pin.
• 8740 chrome plated firing pin, precision ground and heat treated.
• S7 Tool Steel ejector and extractor retaining pin.
• 4130 Steel gas key, phosphate-coated and chrome lined, precision staked and Permatex sealed to the carrier.
• KAK Carrier Key Screws - T25 drive, Grade 8, Properly Heat Treated.
