I have a good buddy who is an FFL and he tells me that rifles should command half of retail the second it is carried outside of the store. However, looking at the gun auction sites and his theory is blown right out of the water. What's more, you just don't see many CZs on the resale market, which, in my opinion, keeps the resale price a tad higher. All-in-all, I would say you should ask for between $545 and $600. This includes around $15 per 20 rounds of the loaded ammunition. Good luck with it ... Tom Purdom
