stuff like this  is one way the Russians stay meddling into our freedom to own bumpstock.   Should the Russians get to the right time where americans can't own bumpstocks they may invade our shores.  In all common sense Stephen who when shoot 550 people in Las Vegas was owning more than one which the limit should be just one.  Most people don't own bumpstock anyways.;  whats a bumpstock looks like?
