i am 18 years old and i am wondering if it is legal for me to purchase a SU-22 in Maryland. Here is what i know about the state laws: 1) i need to be 18 to purchase a rifle or shotgun. 2) i need to be 21 to purchase a handgun. 3) i need to buy from an FFL dealer (duh). what i dont know is the classification of the SU-22 and whether or not i can buy it at 18. if anyone knows the classification and can help me out in any way that would be awesome. thanks.
