Don, have you looked into Skinner sights for that Henry? I'm getting a set to put on my round barrel Henry, my brother has them on his already and loves them.

Also, for accuray testing I tossed a cheap throw-away 4x scope on mine and shot this ten shot group from a kneeling position at 25 yards. Not too bad for a cheap rimfire levergun I figure.
If the golden boy will shoot as good as the cheap models then you've got a winner all around as they look really nice.
