WMD bolt-and-carrier set is precisely machined from high-grade steel alloy to government M16 specs, then given WMD's proprietary NiB-X nickel boron coating that results in a super-smooth, harder-than-chrome surface. NiB-X reduces friction to the bare minimum and is impervious to corrosion and abrasion. Drop in for AR15 / M16 rifles. Quite possibly the finest BCG and finish you will find anywhere.
