you should be required to have to have a automatic weapons license to buy a bump stock, just like a automatic weapon. I own an AR, and the only "practical" use I've seen for bump stocks is spraying hogs at close range, and that's pretty dangerous for a number of reasons. I was always taught to be extremely respectful of firearms because of how dangerous they are and giving a handicap the ability to buy something for under 100$ to make an ar automatic with no modification to the rifle required is loving scary.
