My bolt was a bit rough too. I just greased it up and cycled it a few hundred times, and now it's seems to operate much smoother. The forend of my stock was also touching the barrel in a few spots, so I took it apart and used a dremmel to remove some of the wood. It seems to shoot fine now, as I hit the range the other day, and shot a five shot string that was under an inch...in a 30mph cross wind, no less.
I must admit: The fit and finish on my new CZ 527 left a little to be desired. It has shown a few different times though, it will shoot very well.
CZ will generally make good on they're rifles though. Over on the CZ forums, they looked at a guys rifle and decided it shouldn't have passed quality control. They shipped him a new rifle within a few weeks. I have heard of them doing this on several occasions, when they have determined one of they're rifles faulty or poorly made.
Try getting a new rifle out of Remington, Ruger, and some of the other big manufacturer's....good luck!
In today's mass production world, it's common for bad examples to slip through the cracks, and wind up in the hands of the consumer. It happens with all the big gun maker's too. What I care most about, is how they handle the customer after the fact. So far, CZ seems to be willing to make good on any serious defects.
I happened to break two of the screws off my CZ rings, and I couldn't find suitable replacment screws. I e-mailed CZ's master gunsmith Michael Eagleshield, and asked for the thread size of the screws, so I could find replacements. Four days later, I get an envelope in the mail. It has 3 screws in it, and it had Michaels' CZ business card stapled to the bag. Now THAT is the kind of attempt at customer service that I appreciate!
