I bought a model 94 at a local gun show and the owner had it hanging on the wall with a couple of nails, it fell off the wall and bent the rear sight up pretty bad, can i order another sight from winchester or will i have to get a used one from one of the parts suppliers, its a Therodore Roosevelt, pretty heavy with the 24 inch barrel, shoots good as i can see with the bent up rear sight, i tried to straighten it but its still in pretty bad shape, thanks for your help, WF.
