I am having my Rossi 92 drilled and tapped for a Redfield receiver sight that I recently bought. I have been told that I might have to replace the front sight with a taller one in order to keep from shooting high with the receiver sight adjusted all the way down. The front sight on the Rossi is part of the front barrel band. Does anyone know of a source for taller front sights for this rifle? I am thinking I may have to remove the existing front sight and have a dovetail machined on the front of the barrel for a dovetail type front sight. I want to avoid the expense of this if possible. Any thoughts?
