Some settings on the Eotech and Aimpoint will be too bright(won't be a defined reticle) for sunny conditions. I own and hunt with both an Eotech and an Aimpoint during the summers with no problems. When hunting with a red dot, you have to pay attention to the lighting conditions. I learned this lesson very fast when I went out before sun rise and then had some game present itself at about 0730-0800. Well, I forgot to periodically check/turn my intensity up on my optic to accomodate the brighter light. Couldn't see **** when the pack of 30 hogs started running! This is really an easy check to do periodically and is the only drawback I see to a red dot optic.
Oh and another thing. People will say the Aimpoint and Eotech are only good out to so many yards. Ha, someone forgot to tell me and the 15+ hogs I've hit on the run at 300+ yds. Even smoked one at 460yds. (Laser confirmed) Just got to know your holdovers and leads! The 1 MOA dot on the Eotech is better at those longer ranges, and the 4 MOA dot of the Aimpoint is better/faster to acqurie on the closer shots.
