I will add that if you're planning to take advantage of the Hunter design and think of using irons by tipping off the scope; be selective on scope length. Some scopes are to long to fit between the sights and will require higher rings than what is supplied. The fixed powered leupold's will not be an issue. The 2x Burris will require higher rings or remove rear sight. I think the weaver's require the same, but can't remember for sure. Dan B. should be able to confirm the weavers. If you require the higher rings, all you have to do is call ruger and tell them the issue; then just mail them yours and they will do an even swap.
