WMD Guns Cam Pin Features The WMD Guns Cam Pin is precisely machined from high-grade steel alloy to government M16 specifications ensuring it meets the dimensional tolerances needed for reliable function inside a mil-spec bolt carrier group. It is finished with WMD s proprietary NiB-X nickel boron coating a treatment that produces a super-smooth surface harder than chrome while dramatically reducing friction during cycling. That reduced friction translates directly into smoother more consistent bolt rotation each time the action cycles. Because the coating is impervious to corrosion and abrasion the cam pin holds up to repeated exposure to moisture and rough handling without degrading. The slick NiB-X finish also keeps carbon fouling from adhering to the part so cleanup after a hard day at the range takes noticeably less time and effort than with a standard phosphate finished cam pin. This makes the WMD Guns Cam Pin an ideal choice for 3-gun competitors and other high-volume shooters who run their rifles hard and need consistent low-maintenance performance. Fitting mil-spec AR-15 and M16 upper receivers it serves as a reliable spare part to keep on hand for any bolt carrier group rebuild. The WMD Guns Cam Pin is available for sale at GrabAGun for AR-15 owners who want a durable low-friction upgrade over the standard factory part.
