You just found out most of the realities of the visible laser. I have the same setup as you do. I suspect the reason the dot is dim through your Aimpoint is the coating Aimpoint puts on the front lens to cut glare and keep the red dot from being seen from the front side, just a guess on that though (not sure if that is what keeps the red dot from emitting through the front). Yes, the laser is only sighted in for the range it is zeroed out, that's just basic physics. It will only be good (perfectly on) at two distances, just like iron sights, since the bullet travels in an arc and your laser is straight. Anything before or after one of those points and the point of impact will be off somewhat. If you zero it far away, it will just be that much more off at closer distances. All you can do it zero it at the distance you intend to use it at, and adjust for an offset in your head when the target is not at that particular range, just like iron sights. Commercial visibles lasers are not normally visible in full daylight, only in dimmer conditions, night, or indoors - that's the way they all are. The green laser is apparently brighter to the eye, but no visible laser you are likely to get your hands on will be usable in full daylight. They are simply not that effective. Nothing wrong with the laser, just your expectations. When not in broad daylight, my L72 can be seen up to two miles away (when you track it through magnified optics). It's better than most (cheesy brands) in the daylight, but not expected to be usable under that condition. However, indoors and at night it is awesome. If commercial visible lasers weren't limited to 5mw in power, the situation might be different.
