WMD Guns manufactures this NIB-X bolt carrier group to exacting specifications using Defense Industrial Base suppliers, delivering a BCG engineered specifically around NiB-X nickel boron coating for extended service life and high reliability. The components receive coating and polishing to minimize fouling buildup, while the NiB-X finish itself is guaranteed for life against chipping, spalling, or flaking. Government protocol endurance testing exceeded 30K rounds without coating degradation. The 7.62×39 NIB-X BCG performs especially well in short barrel setups and suppressed platforms.
