'Pawn Stars' Missile -- The Explosive Photo

It's the missile guidance system thingy that launched a full-scale Federal investigation into "Pawn Stars" -- and now, TMZ has obtained a photo of its GREEN ORB OF DOOM.

Okay, we pretty much have no idea what we're looking at -- but we're told it's part of the guidance system used on an AIM-120 AMRAAM missile ... typically launched out of F-4 Phantom fighter jets.

TMZ broke the story ... the person who sold the parts to the "Pawn Stars" guys earlier this month claimed her father bought the parts LEGALLY at a military auction back in the '80s.

As far as we know, the government hasn't confiscated it yet -- but who cares ... look how shiny it is!
