To me, it looks like that barrel was dropped, and contacted something very hard. Sorry, but I can't be certain from the pix, but is the feed ramp dented in or is part of that " circular" dent a protrusion?
I think a careful file ( for the dent at the very bottom of the ramp) and a sanding drum for the ramp itself, followed by progressively finer cuts, ending with a compound polish could fix it.
CZ has a 1 year warranty. I wouldn't be surprised that they reject warranty on that. It doesn't look like a manufacturing defect.
Sorry
I bet if you are careful, you can repair it, with 100% reliability.
If you aren't comfortable doing it yourself, I bet some member here would be glad to do it for you.
Good Luck
