Nice sight - has some great features (no batteries, triangle reticule, very lightweight) but it is not idea.
If you're going to attach it to your carry handle then be sure to use Trijicon's gooseneck mount.
It does not return to zero if you remove it from the carry handle (it will if you have a flattop & use the quick release mount).

Read the LTC Santose's comments then the review (click on the photo or the link at the begining) to get a good overall view of the sight.
