I have just acquired an old 22 cooey[I got it for nostalgic reasons-when I was a kid I would go down to Maple Creek and shoot gophers with a single shot open sighted cooey]However-my eyes aren;t what they used to be,and the rear buckhorn sight just won't focus.I rectified this to some degree by installing a ''true-glo'' front sight on a peepsighted Savage 219 I have-but was wondering if any of the fire sights [front and rear] would fit the old cooey?[It is not grooved,so a scope is out of the question-and unless I could drill and tap it myself ,it isn't economically viable
