Christensen Arms?

Here's another RFI – I've seen some very limited Christensen Arms commentary here and was wondering if anyone has any in-depth experience.

I'm evaluating two models (ELR and MPR) both in .308. I'm weighing against the Sako S20 and I suppose to some degree the Q Fix. I really like the Sako but it is the heaviest at 8.6 lbs. I'd like to get the rifle under 8 lbs before optics, ammo, etc.

One of my biggest concerns with the Christensen rifles are the carbon barrels. Does anyone have much experience with these in real life?

As I've mentioned elsewhere, this rifle will mainly be used to shoot at 300 and 800 yards for fun, and also for some western hunts I have planned. Therefore weight is somewhat of a priority.

Anyone own or have owned a CA rifle?
