I'm a little lost here. According to what I'm reading they all say the same thing. A single pull of the trigger. Even with the"bump stock"you only get one shot every time your finger pulls the trigger. It might arguably be faster using a bump stock but it's still only one pull of the trigger. I know I'm not the brightest bulb around but would appreciate if someone could explain how an accessory to a firearm then makes that said firearm a prohibited item. Fully automatic, far from it.
