The field of field of view through the optic would increase if you were to mount it closer to the rear of the weapon. It looks like it could come back a couple inches and still accomodate a back up iron sight. However, if you feel the rifle is well-balanced with the optic in it's current location and you can put rounds on target, then that is your call, not mine.
I know with my Trijicon Reflex, the further forward I mount the optic, the larger the triangle gets. I realize Aimpoints do not work that way, but having the optic closer to your eye would give you a greater field of view.
