Personally I think 4x20 scopes look best on an Innova.
However, I find it much much nicer to shoot with a 4x40 scope.
The Nikko Stirling 4x20 has milky glass.
The (period) Tasco 4x40 has very nice glass. Such a difference. I can finally see things lol.
So for me it's the 4x40 now. Japanese made, AG4x40WA.
