I have a Winchester model 69A that I got around 1962. I shot it as is for a couple years and then put a scope on to the grooved receiver, removed the original Lyman receiver sight and then foolishly traded it away. I recently decided to return it to its original condition. I contacted Lyman, and although they no longer make the sight that went on the rifle, they did provide the model number. I managed to locate a sight of the correct model on Ebay and purchased it. It fits the inletted portion of the stock and the diameter of the receiver perfectly using the original threaded screw holes. Problem: with the sight screwed down to the lowest possible setting the gun shoots 4" high at 25 yards. Yes, I found the small screw intended to act as a minimum stop and used a jeweler's screw driver to adjust it so it doesn't make contact. The sight just won't go any lower. I never replaced the front post sight and it is not damaged. Does anyone know if some slight model changes occurred over the production life of the rifle? I suspect that the Lyman sight I purchased may originally have been made earlier than my rifle. Cosmetically it lacks the arrows on the adjustment knobs that indicate the direction of travel. If I have to I guess I could have a gunsmith put a higher front sight on it.
