I got my first BB gun before I started kindergarten.
Of course we are talking about New Jersey where it is illegal to buy a SLINGSHOT.
Under New Jersey state law, manufacturing, transporting or possessing a slingshot without “an explainable, lawful purpose” is a fourth degree crime which is punishable by up to 18 months in prison and a fine of up to $10,000.
As I recall, BB guns are considered firearms.
