I just managed to put my hands on a Lyman 30-1/2 rear tang sight for my 99EG. I've been looking for quite a while. Now, I'm looking for a Merit adjustable aperture sight to screw into the 30-1/2. The model I'm looking for is the Merit #4 Hunting Disc, size 4SS (7/32-40 threads). Any advice, guidance, information, etc. would be deeply appreciated.
