How does a cap gun work?
Much like the real gun, there’s a cylinder of copper or brass rotating the new cap in place once you pull the trigger. The hammer is then drawn and released which causes the cap to produce the sound and smoke.
What age is appropriate for a cap gun?
While there are simpler plastic cap guns kids could use up from the age of 3, most are recommended for use for kids of 8 years or up. To be on the safe side and avoid hazards, remember they’re outdoor toys so they're not to be used indoors. Also, never let children use the cap guns without adult guidance and supervision.
