Ok, I picked up a Rossi(Taurus) Circuit Judge about a month ago. I've got an inexpensive red-dot I'd like to put on it (my 10 year old hates iron sights), but want to figure out how to mount it so I can still see the irons. The Judge comes with a short rail mounted on it, and the red-dot has the right clamps for it, but it completely blocks the irons, and it sits too high to see them through it. I know for scoped rifles, you can pick up a set of rings that are open underneath, and you can see the irons, but does anyone know if you can get the same thing that has a rail on top?
Something like this is what I'm thinking:
It only needs to be about 1/2" or so to see through, but with all my google-fu, I haven't been able to find anything.
