Exacting size and oil retention characteristics keep chambers & bores protected and rust free. A proprietary "Dead Cap" insert, made of space-age polymer, absorbs the energy of the firing pin, saving sears and firing pins from damage caused by dry firing. You can extend the life of springs and sears by storing your guns without tension.
For safety training, function testing, or safely decocking without damaging the firing pin, A-Zoom training rounds/snap caps are much more than conventional snap-caps. They are precision CNC machined from solid aluminum to precise cartridge dimensions, then hard anodized for ultra-smooth functioning and long life.
A-Zoom snap caps are proven to withstand over three thousand dry fires while protecting the firing pin. A-Zoom Snap Caps last over 30 times longer than conventional plastic snap caps.
