I am looking for a sight for my Benelli m-90. I think Tru-glo has finally made a sight that fits the rib. I have not seen any for sale yet though. I was considering the tri-viz system which says it will fit any gun. I wondered if anyone has used one, and if they would recomend it. Seems like it sticks up quite a bit and would tend to get damaged. Any thoughts would be appreciated.
