When people buy Automatic Rifle (like AK47,etc.)， they required to do a background check

Automatic rifle is Weapon of Mass Destruction, it is not like handgun. people will need to do background check when you become a volunteer in the library, also if a parent want to drive their children's friend during school time, they required a background check from school. Automatic rifle is the weapon that could lead to grave social consequences，so for this situation, require a background check is actually legit in this case.
