“A three-judge panel for the Sixth Circuit Court of Appeals ruled against the Bureau of Alcohol, Tobacco, Firearms and Explosives’ (ATF) bump stock rule in Hardin v. ATF.

The case centers around a rule made by the ATFs at the urging of then-President Donald Trump after the 2017 tragic attack on country music concertgoers in Las Vegas. The rule reclassified bump stocks as machineguns. The new rule was an about-face by the ATF, which held for years that bump stocks were not machineguns. Initially, the ATF claimed that bump stocks were not machineguns because the user pulls the trigger each time the firearm fires… Since there are multiple circuit splits dealing with bump stocks, SCOTUS is likely to hear a bump stock case.”
