A machinist friend of mine made me up a short ribs sighting system like the Carey one to use. His idea was that I could shoot left handed and use my dominate right eye. I found having two ribs and two sight was too busy for me. I kept looking at both sights and ribs at the same time. Had I only one good eye it might have been the perfect solution to shooting left handed using my right eye sight with. I have used several sight blinders over the years to make cross sighting impossible. Some worked well and many were just junk to throw away.

What I find interesting are the central vision stocks you see at auction sometimes. Be fun to shoot with one for a while.
