Q: Under federal law, airsoft guns are not classified as firearms and are legal for all ages. People under the age of 18 are not permitted to buy airsoft guns over the counter in stores. However, a person of any age may use one (with the permission of their parents, of course, for anyone under 18). This is also the case for the laws in each state. However, in some major cities, the definition of a firearm within their respected ordinances includes propulsion by spring or compressed air, thus making airsoft subject to applicable laws. For example, airsoft guns within the state of California can only be bought by a person above the age of 18. However, no laws indicate an age requirement to sell airsoft guns. Generally speaking, toy, look-alike, and imitation firearms must have an orange tip during shipping and transportation.

A:
do you have to be 18 to buy airsoft guns?
