The largest manufacturer of bump stocks, Slide Fire Solutions, announced it will stop taking orders and shut down its website next month.
Bump stocks are attachments to the stock of a semi-automatic rifle that allow the shooter to simulate a rate close to a fully-automatic weapon.
The bump stock slides back and forth while the shooter’s finger is on the trigger and uses the recoil to fire multiple shots in rapid succession.
A semi-automatic rifle can fire up to 60 rounds per minute, while with a bump stock, the rifle can fire hundreds of rounds in the same period, according to The Associated Press.
