I have owned the Aimpoint and currently own the MOR (dual laser model). I absolutely love the MOR. Almost perfect. The fibre optic light gathering is the best in the business. Far better than almost any ACOG (my TA33 is pretty damn impressive). It is almost impossible to create a condition that washes out the reticle. But there is battery backup with different levels of intensity. At the brightest level, it's like looking into the sun. No other dot I have ever used is as bright.
The battery backup actually consists of two batteries but only draws on one at a time. The second one is for redundancy. So for reliability, you have the fibre optic which is good for most conditions and the battery for all other conditions and a backup battery. The batteries also run the lasers. The red laser is very bright. About 25m in the sun. At least 200m in low light conditions. The lasers are both slaved to the reticle. The IR performs well out to 100m (the furthest I tested it).
The reticle on mine is a segmented circle with a centre dot. This is where the biggest issue arises. The dot is just too big for any "precision" work. At 100m, the dot just covers up too much real estate. Sure 8" plates are a breeze, but don't expect to win any competitions at 100m. Also, the segmented circle is too tight and therefore covers up some of certain types of targets at 100m. I did happen to notice something which helps. If I zero the rifle (in my case a Tavor) at 100m using the top of the circle segment, the target isn't really covered anymore. And coincidently, the dot is then perfect for a 25m zero. Your results may vary with ammo and rifle combos. With a 3x magnifier, I get "combat accuracy". The tritium on the MOR is very bright. But it will slowly fade.
The aimpoint is a fine optic. It isn't heavy, durable (although I haven't done any crazy drop tests on either), great battery life and a much more precise dot than the MOR. Nothing fancy. No bells and whistles.
If your looking to shoot at 200m, go with the aimpoint. Actually, the aimpoint can do most of the important stuff that is required. The visible laser on the MOR isn't really useful for range work. Nor is the IR laser, although it is a nice feature. Ask yourself if you run around with NVG. If not, than the IR is useless too. Then there is the price. While the aimpoint is overpriced (IMHO), it is far cheaper than the MOR version I have ($1600+).
To me, the IR laser, dual battery backup for all reticle conditions, excellent fibre optic, and the tritium were more important to me than dot size (The MOR bullseye reticle is stellar at CQB ranges). It's on a rifle that isn't meant for precision. I loathe batteries and the MOR (and lots of Trijicon optics) eliminate the reliance on them. Have you batteries dying at inopportune moments really sucks. I vowed to never have it happen again. The MOR is built with multiple redundant systems. It won't leave you high and dry.
The perfect red dot optic would be my MOR with a 2MOA dot and cheaper.
So my rambling is done. You are probably going to love the aimpoint. You won't notice the tube effect if you keep both eyes open, like the red dots is how they are intended to be used.
