Very nice sight, wish it would go down to the 2moa dot like version2 will. I think version 2 model will make it the king of the reflex sights on a rifle type set-up. It will have all of the features of the holosun 510c, and the crimson trace rad max, but have the biggest window(I have all 3). No solar power like the holosun though, don’t really care about that point anyway.
