(CNN)The Trump administration rolled out a new federal regulation Tuesday officially banning bump-fire stocks.
Those who possess the devices, which make it easier to fire rounds from a semi-automatic weapon by harnessing the gun's recoil to "bump" the trigger faster, will have 90 days to turn in or otherwise destroy them from the date that the final rule is published in the federal register -- likely this Friday -- according to senior DOJ officials.
Bump stocks gained national attention last year after a gunman in Las Vegas rigged his weapons with the devices to fire on concertgoers, killing 58 people.
Officials at the Bureau of Alcohol, Tobacco, Firearms and Explosives had previously concluded bump stocks were merely a gun accessory or firearm part, not subject to federal regulation, but President Donald Trump called on the Justice Department to outlaw the devices soon after the tragedy.
Justice Department officials told CNN Tuesday they took a "fresh look" at the case law, technology, and the devices and their functionality "in light of modern developments."
The rule concludes that bump-fire stocks, "slide-fire" devices, and devices with certain similar characteristics all fall within the prohibition on machine guns by allowing a "shooter of a semiautomatic firearm to initiate a continuous firing cycle with a single pull of the trigger," and therefore, they are illegal under federal law.
