What is a bump stock?

Answer 1

A stock is the object that the shoulder toutches when firing a rifle. A bump stock is a guns stock that moves back and forth, as to use the force of a gun shot and the mecanism of the trigger to make it fire faster. The finger leaves the trigger and the guns bump stock pushes it forward quickly into the finger again. Each shot is from a single trigger pull, with a bump fire though it is faster, but less accurate and can damage the gun and is expensive on ammunition. A bump stock isn't required to bump fire. A rubber band, a string, a belt loop, or the non-trigger hand can be used to bump fire the gun the same as a bump stock could.
