I've have that exact same Eotech mounted on my AR. Really do love the thing. Plus the fact that is uses plain ol' AA batteries makes it even better. Did you get the Revision F model?
I'm guessing that you are new to all red dot optics and if you are, you should try this and then show your friends.
It's amazing how your brain works.... With the rifle shouldered & both eyes open, take a playing card or something along those lines and cover up the objective side of the sight from the right side (if right eye dominant, reverse if needed). Even without your dominant eye able to see through the optic and only the reticle, your brain will link the image seen by your other eye together.
A video in DRTV video section actually shows this being done with the Aimpoint:
