Not a common rifle that's for sure. They came out about five years ago I believe, a great deal of press about guaranteed accuracy, sub-MOA to a thousand yards etc.
The selling point was that CZ took a standard 550 and toleranced the rifle to ridiculously tight tolerances. Everything about the gun was supposedly built to the most stringent manufactoring tolerances possible. The rifle was sold only in 300 WM and when purchased with the recommended scope, I want to say that it was a Night Force model, it would give guaranteed performance right out of the box. The price as I recall was $1599.00 USD for the rifle and another 1000+ for the glass.
After the initial marketing hoopla faded out it remained in the catalog for three or four years. I believe it is still listed on the web site. That's about all I could tell you about it. I do have a friend that purchased one the first year they came out, at the time he was absolutely thrilled with it. I honestly can't say if he still has it or what his thoughts are on the quality of the rifle today.
Since the CZ 550 UHR was released both Weatherby and Savage have introduced "high" accuracy rifles. Other manufacturers such as Best of the West have released similiar rifle concepts, the 1000 yd rifle right out of the box is a great idea in theory. Something that you would have paid thousands to build is commercially available for the right price.
