Bman940: I would demand an adjustable objective, Du-Plex reticle, at least 16 power on the top end of the variable power and at least 1/4" adjustments at 100 yards (1/8" would be better) for all around useages.
If for Ground Squirrels exclusively then swap out the Du-Plex reticle for a fine crosshair with fine dot reticle.
