Carlson’s Choke Tubes 20 gauge snap caps (part no. 00106) let shotgunners dry-fire, function-test, or safely store a shotgun without a live shell anywhere near the chamber. Carlsons machines each dummy round from aluminum and builds in a spring-loaded primer plunger that absorbs the firing pin’s strike instead of letting it hit bare metal. A wool chamber mop rides on the end of the snap cap, so the same tool that protects your trigger also lets you run a little oil through the bore between uses. Every gun accessory item ships fast from Schaefer Defense, so a pair of these can be on hand for cleaning day and off-season storage in no time.

Key Specifications

• The gauge is 20 gauge, dimensioned to chamber and eject just like a live shell.
• Construction is aluminum, giving the snap cap the durability to survive years of repeated dry-fire use.
• A spring-loaded primer plunger absorbs the firing pin strike, preventing pin damage during dry-firing.
• A wool chamber mop is built into the base, doing double duty as a bore-cleaning tool.
• Running gun oil through the mop after use helps prevent rust from forming in the chamber during storage.
• Each round is inert, holding no powder or primer, so it cannot be fired.
• Each pack contains 2 snap caps, enough for a double-barrel or a pump gun’s tube and chamber.
• Primary use is dry-fire practice, letting shooters work the trigger without any live shell present.
• It also works for safe storage, keeping the firing pin cushioned when the gun sits between hunts.

Frequently Asked Questions

What does the wool mop on the end do? It lets the same snap cap that protects your firing pin double as a bore-cleaning tool — add gun oil and run it through the chamber to prevent rust.

Can I leave these in my shotgun during storage? Yes, that is one of their main uses — the spring-loaded plunger keeps the firing pin cushioned and the chamber lightly oiled between seasons.
