I'm 13 and in the past my dad has bought me shotguns and long rifles. My grandpa has also passed on to me some shotguns and long rifles. My dad has 3 ar 15s. 1 to keep and 2 to sell. I was going to buy one from he but he thinks it is illegal for me to own it. I was also thinking about having my dad buy me a revolver but is it legal for me to own one? Btw I live in Illinois and I do have a foid card. Also the reason I want the revolver is to hunt deer.
