Bumpstocks was name brans and crappy product anyways. It was highly inaccurate, dangerous, and banned on many gun ranges due to safety issues, concerning control on the weapon. Gun enthusiast giggled when it was banned. It was a no brainer as a product that would be a god sacrifice to the anti gun lobby. Not only that, Bumpstock was just rumored to be used yet, not one photographed showed that a Bumpstock was actually used.
