The WMD Guns NiB-X Bolt Carrier Group (brand part no. 1-NIBXBCG762x39) is manufactured by Defense Industrial Base suppliers to WMD’s exacting specifications for 7.62x39mm AR-platform rifles. WMD Guns engineers each BCG specifically for its NiB-X nickel boron coating to deliver long life, high reliability, and easy cleaning and maintenance. The components are coated and polished to reduce fouling adherence, and the coating is guaranteed for life against chipping, spalling, or flaking. It held up through more than 30,000 rounds of government protocol endurance testing without the coating wearing off, and that durability is especially valuable in short-barrel setups and suppressed platforms.
