Lantac's M-SPEC bolt carrier group for .308/7.62 AR-10 rifles is machined to mil-spec dimensions and tolerances. The full-auto profile carrier is 8620 steel, case hardened and hard turned/ground, then QPQ nitrided instead of phosphated for better corrosion resistance. The bolt is Carpenter 158 steel, shot peened, and the group comes with Lantac's CP-R360 domed cam pin to reduce friction inside the upper.
