Those are the reasons I initially thought the M4S would fit my needs. The smaller dot is great, but my only remaining Aimpoint uses are on SBRs. The availability of AAs is extremely attractive, but I now have every optic that eats batteries using the same size lithiums.
Side by side against my H-1, the M4S really is better in every way but weight...I just care more about the latter for my recent builds.
