A U.S. appeals court on Friday struck down a Trump-era ban on bump stocks, devices that can be added to semi-automatic weapons to increase their firing rate.

The ban was enacted in 2018 after a gunman used weapons with bump stocks to kill 58 people and injure at least 850 more in a shooting in Las Vegas in October 2017.

"A plain reading of the statutory language, paired with close consideration of the mechanics of a semi-automatic firearm, reveals that a bump stock is excluded from the technical definition of 'machinegun' set forth in the Gun Control Act and National Firearms Act," the Fifth Circuit Court of Appeals ruled.
