{{Main|Air gun laws}}
While in some countries air guns are not subject to any specific regulation, in most, there are laws which differ widely. Each jurisdiction has its definition of an air gun. Regulations may vary for weapons of different bore, [[muzzle energy]], [[Muzzle velocity|velocity]], or ammunition material. Guns designed to fire [[pellet (air gun)|metal pellets]] are often more tightly controlled than [[airsoft]] weapons. There may be a minimum age for possession, and sales of both air guns and ammunition may be restricted. Some areas require permits and background checks similar to those required for propellant type firearms.
