I can speak personally about Christensen's customer service. I've had a 300 WM by them for about 10 years. The first couple of years, their customer service was excellent. But one year ago the bolts (size M6) holding the pic rail to the action sheared off. I had a very difficult time getting any response from the service dept re sending it in. Then the answer was, "if we can't remove the sheared off screws from the action, we'll have to install a new action." Well, I knew what would happen if I sent it in. So I took it to a local gunsmith and he was able to remove the sheared off screws, and install M8's for $100. That experience has me really soured on CA.
