I really like the Leupold VX II and thats what my 77/22 wears. I have a friend that swears by his Bushnell Banner 3X9 which is mounted on a 10/22. I know he has never had any trouble with it. That might be the way to go if you want to save yourself a few bucks. Bases and rings? I like Leupold or Burris.

Hope that helps some.
