The White Label Armory AR-15 cam pin is a hardened, black nitride coated replacement for the pin that links the bolt to the carrier (White Label Armory part no. WLA-BCG-3020). Inside the bolt carrier group, the cam pin controls how the bolt and carrier interact, so it plays a direct role in the timing and cycling of the rifle. Its low-friction surface supports smoother operation and helps reduce wear. Cam pins are a wear item, which makes this a practical part to keep on the bench for routine maintenance, rebuilds and upgrades. It is made in the USA to mil-spec dimensions.
