I got a bb gun from my mother's boyfriend for Xmas when I was 17. Regular bb gun rifle with the pump mechanism under the trigger just like on a Christmas Story. Took it to a friend's farm to shoot at snapple bottles on fence posts the next spring. I turned 18 in February... Pulled over for driving 33 in a 30 on my way home. Had the bb gun, not loaded, in the hatch area of my sweet 89 Honda Civic hatchback. Spent 25 days in jail and still have a felony charge for an unlicensed firearm in a motor vehicle on my record
Apparently bb guns are totally legal in PA, but require a firearms permit in Jersey
