I suggested a 3-9X33 AO Ultralight as they are very popular on rimfire rifles as they are size appropriate.
Other than in very low light situations there is very little difference in the brightness between the 33mm and 40mm scopes.
Leupold sets the parallax on fixed objective full-size scopes at 150 yards. Ultralight rim-fire scopes are set to be parallax free at 60 yards. An EFR scope has an adjustable objective and can be set to any yardage you choose.
I also have New in the box VX-II 3-9X40 in both Gloss and Matte finish. $280 plus actual UPS Ground shipping.
