Cool article on the Trijicon. Thanks for posting the links.
I have a Reflex with a 4 MOA reticle carry handle mounted on one of my AR's. I can still use my iron sights if need be and, of course, the Trijicon has no batteries.
To zero it, I dialed the reticle onto the top of my front sight post and fine tuned at the range.
Good stuff.
