Brownells 75th Anniversary - A Shooting Heritage

Self-Lubricating Finish For Outstanding Durability & Resistance To Fouling

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. The slick finish also keeps carbon from adhering, so clean up is much faster and easier than with standard parts. Ideal choice for 3-gun competitor sand other high-volume shooters.
