The Lantac Mil-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 Mil-Spec bolt carrier group is made in the U.S.A with a lifetime warranty.

Great value, super slick.


I caught one of these on sale a while back to throw in a budget build to replace a disappointing "Premium" model from a well known shop. The nitride job was easily better than Hodge bcg I have, the domed cam pin is a sweet bonus. Well staked, no machine marks, great coating, highly recommended for the price. I took it out of the budget build and put it in my Recce.
