A-Zoom Shotgun Snap Caps are a safe and effective way of relieving the tension on your gun's firing pin. The CNC-machined construction precisely matches the dimensions of live rounds, and the specially designed Dead Cap lasts 20 times longer than brass caps. The non-corrosive, anodized aluminum finish features excellent oil retention and withstands repeated cyclings in lever action or semiautomatic firearms. A great way to practice trigger pull. Weight: 4 oz. Pack of two snap caps.
