Every Viking Armament NIB BCG set is precisely machined from high-grade steel alloy to government M16 specs, then given a nickel boron coating that results in a super smooth, harder than chrome surface. NiB reduces friction to the bare minimum and is impervious to corrosion and abrasion. The slick finish also keeps carbon from adhering, so clean up is much faster and easier than with standard parts. 100% made in the USA
