Although I don't own a CZ product, I did email CZ last week about a question I had.
I was considering a CZ 455 FS bolt action .22lr and I seen that the 455 series has changeable barrels/calibers. The Lux, American and Varmint models had barrel sets listed in their online store. But, there were no barrel sets listed for the FS models. I wondered if the full stock model could not accept barrels due to the European style stock.
So, I sent an email to their CS in the evening time to see what was what. The next morning I had a reply that the FS version takes the Lux barrel set. They apologized for the confusion and wrote that they would have their web-store guys fix the description. By the end of that day all the appropriate barrels were marked "lux/full stock models" on the web-store.
Even though it was nothing big, it did leave me feeling good about CZ's customer service from that experience.
