If the Supreme Court rules that bump stocks aren’t machine guns later this summer, it could quickly open an unfettered marketplace of newer, more powerful rapid-fire devices.
The Trump administration, in a rare break from gun rights groups, quickly banned bump stocks after the 2017 mass shooting at a Las Vegas concert that was the deadliest in U.S. history. In the ensuing years, gun rights groups challenged the underlying rationale that bump stocks are effectively machine guns — culminating in a legal fight now before the Supreme Court.
Here’s a description of the mechanism, apparently they ruled it wasn’t (edit: a machine gun) back in 1990. It looked like a single trigger pull in the video, but apparently the mechanism pushes the trigger back to reset it quicker. I’m guessing the video was showing the guy tuning it so that the momentum of the gun itself would cause the trigger to be pulled automatically if the finger was held in the right position (he said to lightly squeeze it).
If bump stock is banned, hellfire trigger systems should also be. If hellfire trigger systems aren’t banned, then bump stocks shouldn’t be. At least if they are tuned like that.
Though I can’t think of a good reason to increase fire rate other than for use in combat/attacks when targeting multiple people who don’t have much cover.
