I have found this deer season that my eyes aren't what they used to be, missed three deer this morning. I have great distance vision but can't see close up. I either have blurry sites and see the deer or wear my reading glasses to see my sites but have blurry deer, it's a no win. I have a model 54 Sears made by Winchester and it takes a side mount. What do I need to get it up and shooting with a scope? I don't know anything about side mounts, all the screws are gone from the gun, so the mounts will need to have them. Thanks for any help.
