I'd use a 4X Leupold, and an SSK ( has 6 screws) or Weaver type base with 3 Leupold Rifleman rings.
I've had good success with Bushnell 3200 scopes so far, but I've learned from their binoculars, that when a Bushnell product fails, you may as well throw it away, because their "Warranty" is a sham...there isn't one that they will honor.
