In my opinion, it isn't a controlled feed action if it doesn't feed!!! Kimber have been a lot of negative reviews online lately because of sloppy work. This is the first report on CZ missing the boat. Poor quality control of a Mauser type or Winchester M70 action is a function of the factory and personnel, not the action design. Those actions are designed not to fail, though when you employ people manufacturing them that don't give a flip, you get a worthless action.
I'd be ticked too, but not at the design...
