Here is the problem with Pic of this. When you actually SHOOT with one, that 65yrd ring is HUGE. I have a Troy HK style front site and the two side dashes on the large ring or the whole ring is the same size as the ring of my front site while sighting in.
The pics make it look small compact, but really when you look through it, the bio legs are going to be outside of the actual target. You won't even see them anyway as you focus on the dot!
