Pro-Shot 410 GA Cotton Mop Snap Caps | Shotgun Chamber Maintenance 410SC

Dry-firing a break-action shotgun on an empty chamber is a fast track to broken firing pins and weakened springs. These Pro-Shot 410-gauge snap caps eliminate that mechanical stress with a precision-machined brass base and a spring-loaded primer plunger. Instead of a metal-on-metal strike, the internal plunger safely absorbs the impact, allowing you to function check or store your shotgun without risking expensive internal damage.

Most snap caps stop at protecting the firing pin, but these do double duty for your chamber. The integrated heavy-duty cotton mop is designed to be saturated with your favorite gun oil or rust preventative. Once chambered, the mop physically displaces moisture and coats the steel with a protective barrier, preventing the micro-corrosion and pitting that often lead to sticky extraction and feeding issues over time.

A solid brass base and spring-loaded plunger provide reliable impact absorption during dry fire, while the heavy-duty cotton mop holds protective oil exactly where it is needed most. This dual-purpose design keeps your internal springs under proper tension and your chambers factory-smooth during long-term storage or between trips to the field.
