This type of blank-firing (acoustic) gun is primarily used to produce a pronounced sound – for example at sporting and dog-handling events, for signaling purposes, or as a prop. Specific ammunition compatibility, loading method, and safety features may vary by manufacturer and product version.
Recommendation: Before use, always verify the information on the packaging and in the manual (caliber/type of cartridges, loading method, safety instructions) and comply with applicable laws and safe-handling rules.
