Hands down the X Bolt. There is absolutely no comparison. If you get a Remington, get a used older one as the new ones are plagued with problems. As for scope rings and bases, I really love the Burris Signature Zee scope rings with the inserts. I use them with a Weaver base, but You can also get them in the dovetail style for the Leupold style bases. These rings are the way to go imo.
