I know this a benelli site,dont fear i still have my m2,but the little wife went half on an extrema2 for christmas,and i am trying to find out how to take apart the rotating bolt and firing pin out for cleaning.It is very much like the benelli,but the pin does not have the rubber o-ring on it,seems like it has to be tap out,dont want to break anything.I really could use some help, pictures if possible,thanks
