WMD Guns Part Nib-X BCG without Hammer (NIBXBCG-0001)

The WMD AR-15/M16/M4 Full Auto Bolt Carrier Group without Hammer 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 and does not include the hammer. 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.
