The Trump administration was preparing to officially ban the stock of explosive bullets.
US unnamed officials told CNN on Wednesday that an official device ban would be announced in the coming days.
Hump stocks drew the country's attention after the mass shooting of 2017 in Las Vegas. Authorities said the armed man had used faked weapons during the attack, killing 58 people and injuring hundreds.
When it is attached to a weapon, the device replaces the shoulder rest and adds a small piece near the trigger. This allows the gun to slide back and exploit the kickback power of each shot.
The shooter does not have to move the trigger finger to shoot. Instead, they must just shoot forward on the barrel of the weapon. The weapon "bumps" quickly between the shoulder and the shooter's finger and fires with the weapon much faster than the human being.
A few months after the Las Vegas attack, the Justice Department submitted a settlement proposal that would classify "bump stock" type devices as machine guns and would prohibit the possession, sale, and manufacture of the machines. accessory for firearm.
Since the shooting in Las Vegas, 11 states have banned bump stocks.
The White House has not yet commented on the CNN report.
