Because this is a cross over question I will post it on the three NEF boards. On the 22 RF barrel on the offset VersaPack barrel, is the barrel machined into the breach area with the hinge pin and ejector or is it put on in an offset hole in the piece and then pinned in? I cannot believe that NEF machines a special barrel with an offset chamber because of the work involved, but you never know. Any one with one of these please take a look and see if there is any indication of how it is installed. Larry
