I had one of those scopes on my 20ga. Ultra Slug Hunter for several years. Never failed me. I replaced it with a Leupold 2x7 a couple years ago. You didn't get hurt if it holds up like mine did. I still have it.

Get you some QD rings. (quick disconnect) such as Warne,,Thompson,,,etc. They will make clean-up alot easier. They're not cheap,,but well worth the money. [8D]
