I am currently on my 3rd Cz Ringneck in 28 gauge.
The full disclosure on that is that everytime I take one out in the field with someone, they want to talk me out of it. The first two got sold, and I just about never found another to replace it. Number 3 stays in the box hidden for now, as I will never likely find another replacement. In my opinion, much nicer than any of the recent Huglu guns I have seen out there.
The case hardening seems proper as opposed to the new "Q-Tip swabbed" models. The actual CZ model has the proper baby frame and carries around like a broom stick. Never had any mechanical malfunctions. For the price, it is hard to see how they made any money on it for what appears to be a very well made gun. Ejectors, select trigger, multi-chokes, and a decent piece of Turkish walnut.
My only other experience with Turkish guns is the CZ Uplander Supreme. This one is an o/u 28 gauge with a bit of high relief engraving on the reciever, and upgraded wood (anyone interested, it is currently out on consignment at Shooters Choice). The price on this one was considerably more than what I paid for the simpler little Ringneck, so I may have expected too much out of it.
The gun is still ANIB condition, coming in a moulded plastic case (negrini style) and the only fault I could find with it was that the action was "too" tight. Maybe I'm spoiled with assisted opening in others, but this one is almost a chore to open and close. Needs someone with time on their hands to open and close it a few hundred times while sitting and watching TV!
Mechanically, I have never had an issue with either gun.
