Carlson’s Choke Tubes 20 gauge snap caps (brand part no. 00109) are dummy training shells sold in a 2-pack, built to protect a shotgun’s firing pin and cushion the striker during dry-fire practice. Carlson’s is best known for choke tubes, and extends that same fit-focused engineering to snap caps sized to properly seat in a 20 gauge chamber. These are inert training aids only — they contain no propellant or primer and cannot be fired as live ammunition. In other ammunition, this snap cap pack helps 20 gauge shotgun owners practice safely without dry-firing on an empty chamber.
