The Lantac M-Spec 5.56 Bolt Carrier Group is made to be affordable while still being made from high quality materials with select enhanced parts like the domed cam pin that reduces friction in the upper receiver and decreases parts wear. The bolt face is made from 158 carpenter steel or 9310 depending on supply, shot peened, and magnetic particle inspected. The carrier is cut to full auto M16 dimensions and is machined from 8620 steel and ground to exact Mil-Spec dimensions. The entire AR-15 BCG is black Nitride finished to improve surface hardness and smoothness over traditional Manganese Phosphate. This bolt carrier group is made in the U.S.A with a lifetime warranty.
