From the manufacturer

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 com Mfg: Kak Industry Llc.
