The WMD Guns Beast AR Pistol in .300 Blackout with a 16-inch barrel and NiB-X silver finish (brand part no. 1-556NIBX-300BO) is billed by WMD as the world’s first AR fully shielded by its NiB-X nickel boron coating, inside and out. WMD Guns engineers this coating to guard against moisture, corrosion, and lubricant buildup that plagues uncoated ARs. Among AR pistols, this Beast configuration favors shooters who want a .300 Blackout pistol built to resist fouling and feeding issues.
