It all depends on the country and location where you live

NJ classifies BB guns as firearms. You need a NJ Firearms ID card to purchase a BB rifle or a NJ pistol permit to buy a BB pistol [one permit for each pistol]. Also be aware that the use of BB guns are subject to the same restrictions and legal ramifications as any other firearm.

BB guns are "safer" than powerful air rifles or real firearms, but they are not as "safe" as a toy gun would be that shoots foam darts or something. A BB from even a weak and inexpensive BB gun can blind a person. BBs are dangerous to the human eye for as far as they will travel-- for up to 200 meters or yards, depending on the model of gun and velocity. Kids should learn basic gun safety and gun handling rules before using a BB gun. They should go shooting at least several different times with close adult supervision before they can be trusted to use a BB gun on their own. The kid needs to have a certain level of good judgment, common sense, and respect for the law and respect for other people's property and safety. If all those things are in place, then it's safe for kids to use a BB gun.
