Which red dot or reflex sight ( budget or otherwise) can take the heat; besides an Aimpoint?

I've heard that Eotechs shut off when things get hot?

Thanks.

I have a Primary Arms ?MD 06? iirc, that has been on an Ultimak rail on my Mak 90 AK for several years. After more than 4000 rounds and plenty of heat it still works perfectly. And it has been through several 75 round mag dumps (drum) with no problems as well. Kind of hard for me to justify a $4-500 optic for a rifle I paid less then $200 for back in the day. Those Primary Arms red dots are pretty damn solid, for the money, in my experience.

This is good to know.  Thank you Sir.
