Caveat: I don’t own firearms, and have never fired a live round.

Bump stock is meant to override the need to press trigger each time. It’s my understanding that firearms are designed to fire X rounds per second, and that exceeding that would potentially damage the barrel or other mechanisms since undue heat/stresses would cause the barrel to potentially deform (basic science’y stuff).

If rounds are fired, it causes heat and stress on gun.
If you fire the gun even faster, you’re putting more stress on the gun and increase the heat since the gun isn’t cooling down (even if momentarily) between rounds?

So, the end result would be a gun that is less reliable, more likely to be damaged, and might be rendered unusable because of rifle droop or other damage?

Is that correct?
