I have a 1937 mfg Winchester 69a that belonged y to my grandfather previously. It is dead accurate out to 100 yards and feels perfect for small game hunting but unfortunately the stock doesn’t have studs or swivels. I tried one of the slings that wraps around the stock and barrel but it blocks the sights pretty bad and I hate the way it looks. Should I have studs installed? Will it “ruin” the antiquity of the rifle?
