I’ve had an occluded eye sight mounted on my old Universal M1 Carbine since the ‘80s. It works quite well once you’ve gotten the hang of how to use it (there’s not a big learning curve). However, that might not be a viable solution for Sarge considering his right eye situation. I don’t know.
Wikipedia has some information on these types of sights and
Armson USA sells them. The one on my carbine is an Armson.
Good luck and I hope you find a suitable solution Sarge.
