Product Description
The WMD Guns NiB-X Bolt Carrier Group (BCG) for 7.62x39 is manufactured to WMD’s exacting specifications and engineered around the NiB-X (nickel boron) coating for long service life, high reliability, and simplified cleaning.
Coated and polished components help reduce fouling adherence, making this BCG especially beneficial for short-barrel setups and suppressed platforms. The NiB-X coating is guaranteed for life against chipping, spalling, or flaking, and has demonstrated durability through extensive endurance testing.
