I am having a bit of trouble with rugger scope rings, as you probably know they are made at two different hights on the m77. I am wanting to change from a 50 mm x 1 inch tube scope to a 56 mm x 30 mm tube. Does anyone know if the 5b30 and 6b30 will do for the 56 objective? It doesn't seem to on the chart but I have mounted a 50 mm on the smaller rings.
Does anyone have a spare 6b30 for sale?
