FWIW I just purchased an Aimpoint Micro clone from Ki11ercane and am very impressed by the unit. I am not going to run 500-600 dollar optics on my Archangel 10-22. I do use this rifle for running and gunning and skills and drills as seen in the various Magpul videos.
My overall impression was that this seems like a great value for money. I have no false illusions that this is not the real thing. so my expectations weren't that high.
The dot is a 4moa which is bigger than my NC Star for comparison. All metal construction, click adjustments are audible and tactile in feel. I got the quick detach base with mine, but personally for my head, I found it sat a bit high to get a solid cheek weld. I run a 1/2 inch riser and its great. I thought at first with how small this unit is, that I would have a hard time with target acquisition. Not a problem at all. I do like it better than the NC which is a bigger bulkier unit.
We ran about a dozen course of fire yesterday with them and we were sliding into prone, jumping back into Supine positions, running weak side, strong side drills, urban prone in about a foot of snow. The unit didn't fog at all. The dot stayed bright and true for the 4.5 hours we endured the cold. -20 with 30-40 K winds. The lenses on both units were icing up by the end and when I got home to clean them, it looked like they had condensation inside them. After a few hours, they both seem fine. The laser on the NC star works when it wants to and my #4 brightness setting doesn't work either. I always run it on 5 anyway. That was a significant advantage I found with the aimpoint clone. on the 1 bright setting, I can clearly see the dot on a bright sunny day. The NC Star needs at least 3 to pick it up on a bright sunny day.
I don't think you'll have a problem on a .22 rifle. I put mine through just as much abuse as anyone running an AR platform. Theres just no recoil to contend with on mine.
