WMD BCG NiB-X M16/M4 Bolt Carrier Groups w/SA Hammer

The WMD BCG is precisely machined from high-grade steel to M16 specs before receiving WMD Gun's proprietary NiB-X nickel boron coating. This coating results in super-smooth action, extreme corrosion resistance, and a harder-than-chrome surface that prevents carbon fouling from adhering, making this an ideal choice for any one who does high-volume shooting. This set features a polished finish. If you are looking for a long lasting AR-15 bolt carrier group, the NiB-X BCG is guaranteed to keep your rifle running reliably for years to come.
