This is something I have no experience with, so I'll ask a dumb question I've been wondering: "Then what?"
In other words, if you take the cocking hook off to trial-fit a set of barrels and they do fit, what's the next step - or, how do you go about finding out if the cocking hook will engage/disengage properly without getting stuck? To the un-initiated (me) it seems as though sooner or later you have to take that chance? I can understand the reasons you might want to avoid that situation with a set of barrels that you don't yet own, etc., but when we get down to the business of committing on the new set of barrels for fit, what's the next step?
