what are bump stocks?
A bump stock is a piece of plastic or metal molded to the lower end of a rifle. The device allows a shooter to fire dozens of rounds in seconds by harnessing the gunâs natural recoil. A rifle with this type of mechanism is optimal with a high-capacity magazine that can hold between 60 and 100 rounds and a hand grip that allows a shooter to push the rifle away from the body to bounce, or bump, the weapon into the trigger finger.
