I recently bought a Rossi 92. Regular iron sights suck with my old eyes. I bought a peep, the one on right, MARBLE ARMS : BULLSEYE REAR SIGHT - World's Largest Supplier of Firearm Accessories, Gun Parts and Gunsmithing Tools but have to chamge the front sight as it shoots high. It is a 100 yard gun at best, do I want a 1/16 or 3/32 post on the front sight? I am going with a gold bead unless someone tells me different. Thanks
