Get a look through one first. I did a bit of custom work on a rifle for a friend, and he left it with an Eotech to mount at the end. I took a look through the thing and laughed out loud; it was like some weird laser show effect, this blurry sparkling ring and dot (turned out with the right reading glasses on it was 2 dots, one centred, one just below) which made it basically impossible to pay attention to whatever was in front of the rifle. Like nearly explosive special effects, all shimmering. I can't remember which glasses made it sort of almost possible to look at the thing without just finding it silly, but do remember that although the reticle did become maybe 90% clear, whatever was downrange became a blurry mess with those glasses on. So, impossible to use in combination. There's no way I could use an Eotech.
I can shoot with my Burris FastFire III with 3MOA red dot. It flares out just slightly, but not enough to put me off target. I can shoot with my Holosun gold dot sight too, with a 2MOA dot, and it barely flares at all for me. 2" groups at 50 yards kneeling with that on my GSG-16. So it's not that it's a dot sight. It's something altogether different and weird about the Eotech. And it cost about as much as the Burris and Holosun combined. Apparently my friend can use it okay. Just need to check with your own eyes.
