These Brass Wool snap caps are designed for 12 gauge shotguns to protect the firing pin during dry-fire practice and to help preserve the chamber during storage. Each snap cap uses a spring-loaded primer plunger to absorb striker impact when a live primer is not present. The wool chamber mop can be treated with a light gun oil to discourage surface rust during longer storage intervals.
