WMD Guns is an American manufacturing company that has built a reputation around its proprietary NiB-X nickel-boron coating process. Applying NiB-X to both ferrous and non-ferrous metallic components provides a tough, corrosion-resistant surface with a hardness of 70 Rockwell, a low friction coefficient and increased heat dissipation efficiency. It’s harder than Melonite, nickel Teflon or hard chrome with a slick surface that’s easy to clean.
