From Ammoland:

The U.S. Court of Appeals for the Fifth Circuit overwhelmingly ruled that the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) overstepped its authority when it published a Final Rule that classified bump stocks as “machineguns.” The Trump-era ban was in reaction to the heinous crimes by a depraved murderer in Las Vegas in 2017. The murderer used bump stocks in the commission of his crimes.
