Tell me what practical use a bump stock serves.

That argument is being used by the left already to ban "high capacity magazines" and "assault weapons." When the 3rd Circuit's held earlier this year that the New Jersey ban on magazines with over 10 round capacity did not violate the 2nd Amendment, part of its reasoning is that such magazines are "not well-suited for self defense."

I understand all that but that does not answer my question.
