I have a 558 Tikka in 243. The only thing I would change is the plastic trigger guard and the plastic slide on the back of the bolt. I have never heard of anyone having problems with either, but still . . . It seems funny, we Americans like polymers, plastics etc... on lots of other stuff including our rifle stocks, but on trigger guards etc it makes me feel kind of cheated. Although I knew it was like that on the rifles and my Tikka is one of my favorites
