It manifests itself differently in different optics, but a red dot has electronics in the bottom to bounce the dot against the glass. I'm guessing all the circuitry that hooks the power source (the battery) to the operating guts breaks. I mean I don't know many electronic devices that are going to be happy getting as insanely hot as a barrel can get.
what happen?
it's common to mount optics on the gas tube. The gas tube gets ridiculously hot. Optics often don't like getting ridiculously hot.
Does this melt them, Warp them, or ruin the seals, resulting in fogging? Or something else?
