I understand what bump stocks do from reading up on them, but I haven’t found an explanation of how they work. They allow firing a semi-automatic weapon more quickly by using recoil to move the rifle back and forth (“bumping”) against the trigger finger. What I don’t understand is what is different in a bump stock compared to a regular stock. In my mind, I envision a big cartoonish spring in the bump stock that moves the rifle back forward after the initial kick from recoil. How does it work exactly?
