I didn't care much for the first generation revolutions. The position and design of the action lever felt uncomfortable to me. The action lever on the revolution II appears to have been redesigned and should be more comfortable from what I can see. I haven't heard much about the revolution locally or online. The only person I know that had one commented on the blow back he experienced from the rifle. That was a generation I revolution. The problem might have been corrected on the Revolution II rifles. Now,I've never fired either the revolution I or II, so I can't verify the blow back issue.
I will say that I'm very pleased with the Rolling Block at this point. I got mine in about a month ago. My first range session with it proved to be verypromising. (
