I bought mine in 2018 and have been pretty happy with it. I had to re-tighten the action screws because they were loose when I got it, but it shoots 1/2 MOA all day. With a Leupold VX5 3-15x, I think I'm right at 8 pounds, but I don't know that I'd want to go any lighter for what I use it for. The long barrel gets annoying in any amount of cover but for an open country rifle I don't mind. I may re-stock it at some point with something lighter or more ergonomic for shooting at longer ranges but I'm working on setting up a Kimber Montana in the meantime.
Christensen definitely has had some minor issues with their guns on things like action screw tightness and extractors leaving the factory that don't really expect on an $1800 rifle but I do think the barreled action is tough to beat at the price point if you want a carbon barrel.
