Aimpoint rocks, tritium sucks.
Got my Aimpoint ML2. Good work, Sweden! You look throught it with one eye and have the other eye open and see absolutely no difference in the pucture - as clear, as bright, no shift, etc.
I also tried the tritium-lighted reflex sights. The cheap ones with large ocular and light collector still create a dot that is invisible in bright light - and brighter than necessary in the dark. Especially once one's eyes adapt, one has no way to tone it down.
The much more expensive Trijicon has small window, the dot that was visible better in the bright light but the picture was noticeably darker due to tinted?/layered? optics (which may be the reason why the dot was visible). In the low light conditions the dot is too bright and the extra darkening really hurts.
If I need to see worse in the dark, I can just put on sunglasses or close my eyes altogether.

I did not look at EOTech since it would not allow me co-witness anyway.
