I'd definately get the gun recrowned, but I don't think that overhaul posted by Mr Weasel is so hot, unless you are shooting like shit. These guns are inherently accurate, so decide if you need anything befor you think you need something. Definately get good solid mounts, but I believe that many people go overboard with the rings these days, especially with a 308 or 223. I had my trigger tuned as well as polished my follower for some nice results.
I definately suggest getting the trigger worked before shooting it once, you'll be happy you did!
