i have a 1973 mod 99e that i`m trying to mount a scope on but its not clearing the front sight. its a 1.5-4.5x32 scope with weaver 2pc bases and med. rings. i have the same set-up on an older 99eg with a 3-9x40 and it clears fine. it looks like the sight on the 99e is further ahead on the barrel, not clearing the scope. when the scope is placed in the rings it sits about 1/4" up out of the front ring. will high or extra high rings work?
