Walk into any toy shop and will find an array of airsoft guns that looks just like real weapons. This super realistic aspect makes these weapons very popular with children as well as grown ups, and sales thereof have sky rocketed in the last few years.

Initially these guns were produced to be used in sport where competitors engage in realistic situations and scenarios designed to give the players that adrenalin rush they are after. The mechanics of these guns differ quite a lot from real weapons, in that the propellant used to fire a bullet can never be gun powder.

Gas forms the propellant in these airsoft guns, but other models fire using a spring system or compressed air. Bullets travel at different speeds from different firing mechanisms.

Airsoft guns which work with the gas known as propane top the shopping lists. These weapons store the propane inside a chamber that acts as a reservoir. To keep your gun loaded, you need to keep this canister full by refilling it. Once fired, the propane gas smells a lot like gun powder residue. People who play with these look alike weapons appreciate this aspect.
