You can dry fire a "REPLICA" gun if the action will allow. Some "REPLICA" guns will not have a true action and therefore cannot be fired. NEVER try to load live ammunition in a "REPLICA" gun.

An air gun is usually a replica of a real firearm that is powered by air or C02 that is used to fire a projectile (Pellet or BB). Only air or C02 is used in the air gun. Whereas a firearm uses gunpowder to fire a bullet. Air guns are powerful but not a powerful as a real firearm.
Basically, a non-firing gun, which could be for a number of purposes. In countries with restrictive firearms laws, replicas may be the only way for people to be able to collect firearms. There's the "rubber ducky" replicas, which are a training aid - they're often used in bayonet training, in order to avoid risking damage to actual service rifles. In some cases, a replica is a real gun which has been modified to ensure it cannot fire. In others, it may be made with a rubber or aluminum body, and use components of real firearms. These replica guns are also a great for antique collectors who cannot afford to buy a real gun, so at least they can have a gun in the form of replica. But beware of converting them to real guns as this is the illegal work to do.
Laws on this vary by jurisdiction.
