I went as far as putting a Simmons ProSport 2.5x20mm on a Wolverine of mine. The scope was real cheap. But that is just an awesome little tree stand rifle and walking around rifle. My shots are normally under 50 yards, and that little 2.5 is more then up to the task.
The rifle today had a 4x32mm Simmons ProSport on it and it worked just fine.
