Under Federal Law, airsoft guns and air guns are not classified as firearms and are legal for all ages. Persons under the age of 18 are not permitted to buy airsoft guns, however; a person of any age may use one.



There is no age restriction when buying BBs or other accessories. However, items such as GAS, CO2, SMOKE GRENADES and FLASH BANGS may have an 18 years restriction applied.



There is no age restriction to own or to operate an Airsoft Gun. It is within the law for a person that is 18 years or over to purchase an Airsoft Gun and gift it to a person that is under the age of 18 years of age to own and operate. So, a parent can buy an airsoft gun and give it to their child to use or keep regardless of their age. We recommend that an adult should supervise persons under the age of 14 years.
