How a bump stock works — VIDEO
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.
