Is there any overwhelming consensus over where to mount a red dot (Aimpoint T1 for example)? I've seen them from one end of the rail to the other. I have mine centered over the bolt release, not by landmark, but just by me moving it back and forth until I felt a balance between useful image and eye relief. Other positions either made it too small or "off axis" or led me to start closing one eye. Obviously some positions are even fixed, like some piggy-backed or offset/side mounted brackets. Thoughts?
