Product Description
The WMD Guns NiB-X Bolt Carrier Group (BCG) with hammer for 5.56 platforms is built for reliability and simplified maintenance in demanding AR-15 setups. Its bolt carrier group components are NiB-X coated and polished to help reduce fouling adherence, making cleanup faster and helping the action run smoother. The NiB-X coating is backed by a lifetime guarantee against chipping, spalling, or flaking, and has been endurance tested past 30,000 rounds without wearing off. This easy-clean design is especially beneficial for short-barreled rifles and suppressed configurations where heat and carbon buildup are common.
