Maybe I'm not seeing straight but the first guy doesn't seem to pull the trigger...
He doesn't seem to **** it properly, then his finger doesn't seem to be on trigger as it clicks.
He then makes a much bigger effort of cocking it and hands it over... Weird.
In fact, watching it again, the sound of cocking it seems way out of sync of the action. I CALL FAKE!
Also, I know all about guns cos I play COD.
