I'm wanting to put a reciever sight on a winchester 94 - 30/30, and use it as the primary rear sight. What sight do you recomend, pros and cons. I'd like a metal sight as to an aluminun made one, is finding one in exclent shap hard to do these says, or would it cost an arm and a leg. Seems i've seen them at the gunshows and they are proud of them! Is the aluminum sight o.k. to use?
