The Trump administration is reportedly getting ready to officially ban bump stocks on guns.
Anonymous U.S. officials told CNN Wednesday a formal ban on the devices will be announced in the coming days.
Bump stocks got the nation's attention after the 2017 mass shooting in Las Vegas. Authorities say the gunman used weapons rigged with devices during the attack, which left 58 people dead and hundreds more injured.
When attached to a weapon, the device replaces the shoulder rest and adds a small piece near the trigger. This allows the firearm to slide back and forth and harness the recoil power of every shot.
The shooter doesn't have to move the trigger finger to fire. Instead, they just have to pull forward on the barrel of the gun. The weapon quickly "bumps" between the shooter's shoulder and finger, firing the weapon much faster than a human could.
A few months after the Las Vegas attack, the Justice Department submitted a regulation proposal that would classify bump-stock-type devices as machine guns and bar the possession, sale and manufacturing of the gun accessory.
Since the Las Vegas shooting, 11 states have banned bump stocks.
The White House has yet to comment on CNN's report.
