John, you seem to be confused with what I am saying, I am talking about the method of attaching the barrel to the action, not the action itself. The M12 is very different to the M98, I know as I have owned both and still have 98's but that doesn't mean that the barrel can't be attached the same way on the new model. Until the M12 came along no other rifle barrel has been attached permanently, at least not that I know of.
Anyway it is just something I have been wondering, of course if you know differently for sure that is, not just guessing, than tell us.

Waidmannsheil.
