A-Zoom 12311 Snap Caps for 12 Gauge Shotgun, Aluminum, Blue, 5 Pack

A-Zoom Centerfire metal snap caps are precision CNC machined from solid aluminum to precise cartridge dimensions, then hard anodized for ultra-smooth functioning and long life. For safety training snap caps allow you to release your firing pin without damaging your gun. You can practice sight control, trigger squeeze, and check the weapon's cycling as well. A-Zoom training rounds are much more than conventional snap caps.
