WMD Guns NIB-X Cam Pin – AR-15/M16 5.56

The WMD Guns NIB-X Cam Pin replaces the factory cam pin in AR-15 and M16 bolt carrier groups. This small but critical component guides the bolt during lockup and unlocking. Upgrading to a NIB-X coated cam pin reduces friction and wear on both the pin and the upper receiver's cam pin channel, extending service life and improving reliability in adverse conditions.

Constructed from hardened steel and finished with WMD's proprietary Nickel Boron-based NIB-X coating, this cam pin offers superior lubricity and corrosion resistance compared to standard phosphate or uncoated pins. Installation is drop-in with no gunsmithing required—simply remove the bolt from the carrier, swap the cam pin, and reassemble. The self-lubricating properties of NIB-X reduce the need for additional oil in the cam pin channel.
