Well son...Have you got some options and choices ahead of you...
You can choose the Ultra Slugger in 12GA or 20GA:

or the Ultra Slugger Deluxe in 12GA or 20GA:

or the Tracker II in 12GA or 20GA:

The Ultra Sluggers do not come with rifle sites but they are drilled and tapped for a scope rail and the rail is already mounted on the barrel...You must purchase a scope and rings. The Tracker II comes with rifle sites but is not drilled and tapped for a scope. H&R recommends that you do not d&t the Tracker II but many here have done so successfully.
The Ultra Sluggers are quite a bit heavier than the Tracker II so the felt recoil is lower but they are tougher to haul around in the woods. If you are a sitter then an Ultra Slug may be fine for you...If you love to stalk all day the Tracker II may be a good bet for you.
