ON some 94's there is a second adjustment that can allow for the rear sight to go higher on the ramp
but again, there are SO many different models of 30/30 by Winchester, not knowing what model you have, and or sights ON said model
its very hard to offer more help
there is always again, the option of changing sights, be it front or rear to make things work and since you haven't I gather owned gun since NEW< no clue as to if previous owner changed sights??
but its all fixable for sure with not a lot of mods needed to do so!
please post what exact model and possibly even take some pic's of sights on gun, to help US , help YOU better!
