Originally, dad had a Bushnell Banner on there. It was sighted in when it was installed and it was dead on for over 20 years. Then it fogged up. And Bushnell replaced it with their base model 3X9-40. It is total garbage, I've got two Bushnell 3x9-40's on my 10/22's, and has way better optics. And dad was never really happy up to his death about the replacement scope. It bothered him for a long time, and it bugs me to this day that he wasn't happy with it. So, I want to do it right for him. To honor him.
I definitely want to get either a Leopold, or a Burris for sure. I love Leo's for the fact that their headquarters is based little over an hour from me. And I have a pair of their Windriver 10X40 binoc's, that are incredible.
