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
Inertial impact of the cycling bolt (recoil) has enough motion on the overall firearm to allow for a trigger reset, and with muscle memory the trigger finger can be placed at the breakpoint of the trigger for a fire rate close to or at the cycle rate of the firearm.
It does not increase the cycle rate of the firearm (that is static and based on the bolt weight / buffer system). It does make it easier for a person to shoot faster than they normally could. But anyone proficient with their firearm can do the same with or without a bumpstock.
