I think there newer stuff shoots pretty solid. Actions have gotten smoother, the barrels from the last few years seem to shoot better as well.
I have one of their older rifles. They spun a new tube on it while back and it definitely does better than the old one ever did. I've heard some pretty good reviews on their MPR as well.
But like others said, unless Christensen has a rifle exactly like you want or you need a factory gun (nrl hunter divisions etc) then you'd be better served with having a smith spin you up exactly what you want.
