A-Zoom .300 AAC Blackout Snap Caps, 2-Pack

A-Zoom .300 AAC Blackout snap caps (part no. 12271) are inert dummy rounds built for dry-fire practice, function testing, and safe disassembly — they carry no propellant or primer and cannot be fired. A-Zoom molds each cap to the dimensions of a live .300 AAC Blackout round, so it feeds, chambers, and ejects like the real thing without ever risking a live discharge. In other ammunition, this 2-pack is the safe way to work a trigger, check function, or teach a new shooter without a single live round in the gun.

Key Specifications

• The chambering is .300 AAC Blackout, sized to feed and chamber exactly like a live round in that caliber.
• Each pack contains 2 caps, enough for repeated dry-fire sessions before replacement.
• The cap is inert — it holds no propellant or primer compound and cannot be fired, discharged, or made to function as live ammunition.
• A spring-loaded internal cushion absorbs the firing pin strike, protecting the pin and disconnector from the metal-on-metal impact of dry-firing without a snap cap.
• The caps are reusable, standing up to hundreds of dry-fire cycles before the striking face wears out.
• At roughly $ per cap, replacing a worn snap cap costs far less than a firing pin repair from dry-firing without one.
• A-Zoom builds these for function checks and disassembly practice — cycling the action, testing the trigger, or teaching safe handling with zero live rounds present.
• A-Zoom is a working gunsmithing and shooting-accessories brand, and this snap cap is sized specifically for .300 AAC Blackout rather than sold as a generic universal fit.
