A-Zoom Shotgun Snap Caps are designed for safe training, function testing, and decocking without causing damage to the firing pin. Each snap cap is CNC-machined from solid aluminum to exact cartridge dimensions and finished with a hard-anodized coating for smooth cycling and long-lasting durability. Built for reliability, they feature A-Zoom's proven "Dead Cap" design, capable of withstanding more than 3,000 dry fires while effectively protecting the firing pin. These snap caps provide a safe and practical solution for practicing loading, unloading, and trigger control, making them an essential tool for both training and firearm maintenance.
