I've got the exact rifle you inquire about in .308. Cons are pretty much aesthetic. To some it's just too "plasticy" in both look and feel. I also replaced the factory recoil pad with a limbsaver since the factory one isn't all that. The factory rings aren't terribly appealing but many people use them without complaint. I put Dednutz on mine.
Otherwise, it's easily one of the best deals going.
