Got to use my T-2 a bit today. It literally feels weightless on the gun but I still like my M4. The dot may seem a BIT more crisp but it could be in my head. It seems on higher settings especially in less light its easier to get the big red ring around the lens from the bloom as well as a ghost dot a 5 O'clock than an M4 is but it is nothing that matters in actual use.

It is so small it looks out of place on a rifle almost but it is the first optic I've ever put on a gun and couldn't feel the weight difference.
