Barrel appears to be walking out?

[G.T.]

After thinking about this "hot mess" for awhile, I realized that there was an option we should consider, and that is to cut the barrel off and drill / mill, out the remained of the barrel stub / tenon, until we can pry out the remained, and address the pin from both inside and out? No reason that the receiver would not work, unless of course, cracked or squished??? Just me thinking out loud! Best, til...lat'r....GT....
