I haven't noticed the drift issue but I also haven't used my Eotech much (nor have I done any accuracy testing in different temps).
I like the fact that the EOtech is not a tube as I feel it gives me greater FOV. I also like the reticle (dot plus circle). But I'm not finding anyone else that has that dot circle configuration.
What should I get as a replacement?
I don't remember the temp I zeroed my eotech at but I know it was warmer (like a lot) than however cold it will be outside this weekend lol. So i'm gonna go to the range and do some accuracy testing.
My replacement of the EOTech was forca few reasons... 1. They lied, screw them. 2. After using EOtech for 6 years or so and getting glasses in that time I've found out have much my astigmatism effected what the reticle look like.... To the point where its hard to use the optic now without my glasses. I never noticed it before, I just thought the reticle was "fuzzy". Becuase of reason #1 and given teh opportunity to get a full refund I decided to switch.
I prefer the " heads up display" vs tube style optics but I guess that's becuase of how long I ve been using an EOTech. My EOTech 556.a65 came off my Tavor and that's currently the only firearm I run a full size, non magnified dot on.
I don't know of another quality optic that offered a larger ring around the primary aming dot at the moment, but for me personally my buying concerns don't require a outer ring they require a 2mao dot that's reasonably clear with or without my glasses. Concern #2 is durability/warranty, concern #3 is weight. Concern #4 is overall price. No magnification is also a criteria
That's how I came to my list.
If money was no problem I would look closer at the Meprolight MOS. But, I have an issue with the warranty and potential long term support (that is not based on fact, just my concern)
Out of my list, my FAV is the Trijicon MRO.... But I have personally witnessed all of the major complaints out there both on the retail models and in a friends carbine. That's isxthe sole reason why the Aimpoint Pro sits (currently) on the top of my list
