I have a sporter 1903 springfield mark I. The rear sight base has been ground flat and has a Redfield sight on the rear. Have ordered a new stock for it and am considering optics as I want to complete the sporterizing and make it into a functional hunter. Any thoughts on scope bases, drilled and no drill and also on metal refinish. Looking at cerakote or an hot blue. Other option is to remove the rear sight base and either leave it off or replace with a used/aftermarket one and use the scope base that mounts on the original rear base. Thoughts? Can add pics if that would help.
