Oregon45, thank you very, very much for your reply. I made the same post in four different gun forums and yours is the absolute best answer I have received. I sincerely appreciate it. My CZ 550 is also an FS model and while I do like the Mannlicher style stocks, I was hoping for something slightly more practical. Looks like you can just remove the action from the stock and take off the end cap, huh? Thanks again.
