DN Spy gave you some very good info. I've got 3 of the Micros, 2 on rifles and one on a T-C Contender. Also have 4 others Red Dots, 2 Tasco & 2 Bushnell that have not given me any problems but which I would say are not near the quality of the Aimpoint.
Just a thought..........buy a used, CHEAP, one of some sort, mount it and shoot it a bit. If you like it get a good one.....if not you can sell it for not much of a loss.
