The Pro-Shot 12 Gauge Semi-Auto Snap Caps (Model: 12SEMI-SC) are precision-machined, all-brass inert training rounds engineered for 12-gauge firearms. Built specifically to function smoothly in repeating actions without the obstruction of a bore mop, each dummy round features an internal spring-loaded false primer. This mechanism absorbs the kinetic impact of the firing pin during dry-fire practice, preventing pin breakage and relieving spring tension before storage. In Australia, these inert accessories are non-regulated and serve as essential tools for safe trigger training, function testing, and action cycling across semi-automatic, pump-action, and break-action platforms.

Key Features

• Spring-Loaded Primer Mechanism: Internal spring-cushioned false striker absorbs the firing pin's strike force, protecting the internal action from battering during dry fire.
• Repeating Action Profile: Precision all-brass construction without an attached mop allows smooth feeding, chambering, and extraction in repeating shotguns.
• Storage Spring Relief: Enables safe decocking of the firearm prior to long-term storage, relieving continuous tension on hammer and firing pin springs.
• Durable Machined Brass: Resists rim damage and extractor wear across repeated cycling compared to plastic or polymer dummy rounds.

Who is the Pro-Shot 12 Gauge Semi-Auto Snap Caps for?

• Semi-automatic shotgun owners practicing dry-fire drills — Requires a mop-free, solid brass 12 gauge semi auto snap cap supplied in a 2-pack quantity to safely drop the hammer and run trigger-control drills without risking firing pin damage.
• Shooters testing feeding and cycling in repeating actions — Relies on precision-machined brass dimensions built strictly for standard 12 gauge chambers to test cycling, chambering, and extraction through magazines and repeating mechanisms using a 2-pack of inert rounds.

Less suitable for: Owners of smaller shotgun calibres such as 20ga, 28ga, or .410 bore, which require dedicated, calibre-matched sub-gauge snap caps to fit their narrower chambers.
