Something that fits (when stock is brought to cheek no adjustments need to be made) in suitable caliber with scope of 2-3-4-to-6-7-8-9-10-12x and objective diameter of 36mm to 42mm and max weight of about 16oz (which usually means 1" tube). The key is proper stock fit and gun balance (good weight distribution) which is more important than anything else. I also insist on no recoil pad, but that is just personal preference.
