FILE - A bump stock is displayed in Harrisonburg, Va., on March 15, 2019. The Supreme Court has struck down a Trump-era ban on bump stocks, a gun accessory that allows semi-automatic weapons to fire rapidly like machine guns.
The Biden administration said that the Bureau of Alcohol, Tobacco, Firearms and Explosives made the right choice for the accessories that can allow weapons to fire at a rate of hundreds of rounds a minute.
Bump stocks are accessories that replace a rifle’s stock, the part that rests against the shoulder. They harness the gun’s recoil energy so that the trigger bumps against the shooter’s stationary finger, allowing the gun to fire at a rate comparable to a traditional machine gun. Fifteen states and the District of Columbia have their own bans on bump stocks.
