American Built Arms Company Cam Pin Features The American Built Arms Company Cam Pin is coated in nickel boron a finish prized for its low friction and corrosion resistance inside the AR-15 bolt carrier group. Because the nickel boron coating resists carbon buildup and runs smoothly against adjacent surfaces the cam pin needs virtually no lubrication during extended use. This helps keep the action cycling cleanly even when range sessions run long or maintenance intervals get stretched. The result is a small part that contributes real reliability to the overall bolt carrier group. Sized for AR15/M16 pattern rifles the cam pin is ready to drop directly into a compatible bolt carrier group without fitting or modification. This makes it a convenient upgrade for shooters replacing a worn factory cam pin or building out a bolt carrier group with upgraded low-friction components. The nickel boron finish also makes inspection and cleaning easier since fouling wipes away more readily than on a standard phosphate finish. For AR-15 owners seeking a durable easy-install upgrade this cam pin is available for sale at GrabAGun.
