WMD Guns NiB-X AR-15 5.56 Bolt Carrier Group Without Hammer

The WMD Guns NiB-X bolt carrier group is a 5.56 M16 pattern BCG with every component NiB-X nickel boron coated and polished. The slick, silver finish resists fouling, so carbon wipes off instead of baking on.

WMD guarantees the coating for life against chipping, spalling or flaking, and it held up through more than 30,000 rounds of government protocol endurance testing. It is a good fit for short barrels and suppressed rifles that run dirty. This SKU does not include the coated hammer.
