The world's first AR fully shielded by WMD's proprietary NiB-X nickel boron coating process-inside and out! Lesser ARs are much more vulnerable to moisture, corrosion, lubricant buildup, and powder fouling. But the 5.56 Beast from WMD is practically unstoppable, thanks to WMD's NiB-X coating technology. NiB-X not only guards against friction and wear, but also virtually eliminates feeding problems caused by lubricant and residue buildup.
