I have the Ridgeline in 28 Nosler. I'm very happy with it but it needed some work to be perfect.
1. Stock needed to be bedded. It had some pretty large voids, several 1/4" diameter, where you needed contact with the action.
2. Action screws were too short. Only had about 1.5 threads of engagement (you can get 5+ threads with a properly trimmed screw).
3. Magazine spring needed replaced. The spring was a bit too tall, so the third bullet would fit too tightly, and it would just vomit all the bullets up and out of the magazine when you pulled the bolt back.
I didn't bother contacting Christensen to fix these things, I just did them myself. Maybe they would have fixed them for free? Having done that work, it now shoots consistent 0.3" groups at 100 yards with handloads. No issues with a sticky bolt for me.
Another note on the stock. Its a minimalist profile. The forend is so narrow that you can't even get a harris bipod to stay on the swivel stud. Not really a problem for me but something to be aware of.
I stacked discounts and got it for about $1500 from Cabelas. Its definitely the best value carbon barrel rifle out there. There isn't much difference between the Ridgeline and the other carbon barrel Christensen's, some of which are way more expensive. The Ridgeline still comes with a match grade carbon fiber barrel, a custom action, and a Triggertech trigger. The other models have better shaped stocks, and some are full length bedded, but in my opinion not worth the extra money.
