There is no age limit.
Of what state and country
there is no age that you have to be to play airsoft I've seen kids as young as 5 playing. EDIT: There is no legal age limit on using an air-soft gun but you do have to be 18 years of age or older to buy one from a store.
The minimum age is 17 for an air-gun (rifle or pistol).
since an airsoft gun is considered a toy it is legal for any age but you have to be 18 or older to buy it
It depends what country you're in. Here in the UK, you can buy an air-gun at age 17. Other countries have different laws.
There are bio degradable bb's for Airsoft guns but not for real BB guns.
for ne state im pretty sure that u have to 18 years or older in order to buy an airsoft gun
The legal age to buy a gun depends on the type of gun it is. For an example, to buy a rifle or shotgun(excluding assault rifles) you must be 18 years of age. To buy a handgun you must be 21.
Think about the legal age to buy a gun. It's probably around that age.
18

There is no set age limit for cap gun ownership.
