''A bumpstock has no such alternate utility. It's only purpose...'' And, lets not forget that the bumpstock design has a lever that locks the stock...making it just like any other stock as non-moving It was NEVER proven in the most delcarative arena allowed within our nation, COURT, that dude used the stock. I will not write it all again. Here... Here's FACTS, decided in ....COURT... https://www.ammoland.com/2019/03/gun-owners-of-america-day-court-bump-stocks/ re: '' GOA’s attorney countered by telling the judge there is no actual proof of one recorded instance where bump stocks have been used in a crime. Olson even cited the lack of FBI and ATF statements, studies or reports to demonstrate that there is no conclusive evidence that a bump stock was actually used by the Las Vegas shooter. This was something of a “mic drop” moment, because when given the chance to respond, the government’s lawyer could not — in fact, he refused to — counter Olson’s statement on this point. Thus, the oral arguments in the Western district federal court on March 6 established unrebutted testimony that, to date, there is no proof of any documented case where a bump stock was used in a crime.''
