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?
In: Physics
The stock is able to float back and forth about an inch. You start with it fully extended.
You pull the trigger, the gun fires and recoils back into the stock.
As the gun goes backwards, a protrusion from the stock pushes your finger off the trigger so that it can reset.
You pull the rifle forward with your support hand and doing so it pulls the trigger into your finger and it fires again.
By simultaneously pulling backwards with your trigger finger and pushing forwards with your support hand, the system forces your finger to keep on firing and releasing the trigger pretty quickly.
