I have a Romeo. It's back In the box it came in and replaced it with an eotech. Nowhere near robust enough for a tool that is intended to get rough treatment. Everyone is different, my 556 gun is a truck/sxs/farm tool. Has to take a beating. What changed my mind is the mounting bolt on the base is about half the size of the single mounting bolt on my rear sight. In my world I do not see it staying attached to the rifle very long.
