It was Redneck Tactical (Mike Pinto) that was getting the shotguns from CZ. IIRC, Nordic Components was going to make a tube extension for them to put on it. There will have to be several mods done to it. They may not even have it or other components yet, due to the shot show just wrapping up not too long ago. And testing it out would be difficult with the weather last week.
All I'm saying is that everyone is excited about this, including RNT. I'm sure Mike will update us when they have something to report, we just have to be patient. No harm in asking, I was just answering your question of "what ever happened to that".
