Really early Model 760 rifles (from the fifties) came with stocks having lower drops that are better suited for use with iron sights. Later Model 760s (and, of course, the Model 7600) were made with stocks having a higher comb, giving a better stock "weld" to eye relationship when using scopes. My Model 760 was made in the early fifties and I have a Williams FoolProof receiver sight mounted on it. It's a fast-moving set-up that has accounted for more than a couple of whitetails in heavy brush and Michigan cedar swamps over the past several decades.
