I was surprised and disappointed to see that the Ultradot is a tubed sight much like the Aimpoint and others. I really don't like that style of sight as it just does not provide the immediate and easy sight picture that the Eotech's do.
Regardless of what some think of the Eotech, our special forces do apear to like them and I often see them on the weapons they chose to preserve their lives and the lives of their comrades. A higher and more meaningful tribute cannot be obtained.
