PMI Piranha Long Barrel later model - used shape for parts

PMI Piranha Long Barrel later model - used shape for parts. See photos.
Missing front sight pin.
Has Auto Trigger set up, likely needs adjusting
Has wear from use and from sitting for decades. Speed demon Bolt is missing pin to hold it together. Wear on bolt and barrel. Untested. This will definitely need valve orings changed out and the hard line orings changed.
