Hardly the same. The Urika, Urika Optima, Teknys and Urika II work. The Remington didn't.
There is one minor mechanical difference between the Urika and Urika II. It is a serrated gas piston. The other difference is cosmetic with the offering of the Xtra-finish on the stock.
Having (again) fallen victim to the magazine reviews I was keenly looking forward to trying the CTi. The design was unique and a couple of the features intrigued me. When I eventually got one in my hands what I saw was a piece of overpriced crap. Maybe their newest version of it will be better but I'll let someone else do the Beta testing on Remington's 2nd attempt.
Meanwhile I'll stick with my 391 Sporting and continue to hope that one day Beretta will make it in 28 gauge.
