LT755-30-T pivot mount places the magnifier 1.725 centerline height-alignment above the rail. The LaRue LT129 mount places the centerline height-alignment 1.7 above the rail. So the Pivot Mount Tall will work well with an Aimpoint Pro mounted on a LaRue LT 150 (best) and LT129 mount. I'm not sure what the standard Aimpoint Pro centerline height-alignment is.
