All the men have the stock deep in the socket .. only the girl has it high ..
I think that is a .22 cal. pellet gun THE FOREIGNER is firing.
Judging by the smoke expelled, no kick and location of the butt and shoulder. If that is a 12 gauge, it appears the kick would already be in progress and his shoulder would probably be broken.
What is the object at the end of the top barrel? Is is a bore reducing sleeve?
Notice the gas ejection from the right side of the barrel. It must be ported. If it was ported a barrel reducing sleeve would have to be ported too.
Some have suggested the object at the end of the barrel is a blank adapter. I have never seen one, but this is a double barrel action, no gas driven automatic. There would be no reason for a blank adapter.
Very strange photo, but it reveals a lot about Obozo.
