Has anyone done their own tests to verify this? I find it a bit curious that until recently, I don't really recall anyone complaining about their Eotechs being way off from one day to the next based on weather. I've had a 512 for almost 6 years now without noticing a zero issue. When I get back stateside I'll have to go out on a cold day. The last two times I shot with it, it was right on. I'll have to see if I'm now off. I just can't imagine there being such huge differences based on what I'm now reading, though I don't think I've ever shot it in subzero temperatures. That is scary bad, what they are saying.
Well, the report linked above says that not a single EoTech ever even passed their own internal testing of zero drift. So, I'm guessing that means yes, every single one has this problem.
