The U.S. Supreme Court on Thursday ruled that a bump stock does not transform a firearm into an automatic weapon, striking down a federal rule that banned bump stocks.
In a 6-3 decision, Justice Clarence Thomas wrote, "Congress has long restricted access to "'machinegun[s],'" a category of firearms defined by the ability to "shoot, automatically more than one shot . . . by a single function of the trigger."
"Semiautomatic firearms, which require shooters to reengage the trigger for every shot, are not machineguns. This case asks whether a bump stock—an accessory for a semi-automatic rifle that allows the shooter to rapidly reengage the trigger (and therefore achieve a high rate of fire)—con- verts the rifle into a 'machinegun.' We hold that it does not," he wrote.
