Just wondering if the dot optics...namely the Eotech, are EMP proof. With all this SHTF talk and such I gotta know, think an Aimpoint or EO can work post-EMP? Chime in professionals, or anyone who slept at a Holiday Inn Express last night!

There have been quite a few discussions on this already.... Basically the consensus is, that small electronic devices like the Aimpoint and EOTech are too small, and dont have enough wiring in them to act as a big enough conductor.
The Aimpoint is just a battery connected to a variable rheostat, then connected to an LED. there are no circuit boards to be damaged. The EOTech I think has some electronic boards in it, so if you were close enough to the EMP it might hurt it, but I would be MUCH MUCH more concerned about the radiation effects than the EMP effects if you were that close

I believe Aimpoints have circuitry to extend battery life, so they are vulnerable to an EM pulse.
If it's a small pulse, red dot sights should survive. If it's big (like a nuke) they'll go. Sad part is that cheap Chicom knock offs that really are just a battery, manual switch, wires, and diode, could fair better. Of course if the radiation is strong enough to fry the battery, you won't last long enough to worry about it. |

A ground burst is a different scenario however. IMO |
