Technology: what is a bump stock?
Self-tutoring about firearm technology: the tutor mentions bump stocks.
To understand a bump stock, one must first understand semi-automatic vs automatic. Semi-automatic guns require a distinct trigger-pull for each shot, with a trigger release in between; automatic, the shooter can just hold the trigger in firing position for repetitive fire.
A bump stock is an attachment installed in place of the original stock. The difference is that a bump stock can vibrate back and forth in response to recoil, independently of the barrel. As the bump stock vibrates back and forth, it can cause the shooter’s hand to release and repull the trigger without the shooter actually opening and closing their finger. You could argue the gun continues firing “automatically” until the shooter purposely releases the trigger.
To my knowledge, a bump stock’s use is on a semi-automatic gun, making it fire repeatedly from a single pull. Even though, with a bump stock installed, you can get repeated fire from only squeezing the trigger once, the firearm remains semi-automatic since its trigger is pulling and releasing to cause each shot. It’s just that the user doesn’t need to pull and release; if they just keep their finger squeezed around the trigger, the recoil vibration “bumps” the gun back and forth, causing the trigger to engage and disengage until the user purposely draws their finger away.
Not too surprisingly, bump stocks are controversial. I’ll follow up.
