I recently bought a giant pile of GI Joes. In my pile I found Heavy Metal, he has a reproduction mic so I was just wondering if the gun was also a repro. Is there an easy way to tell. I'm used to doing the float test with star wars weapons but was unable to find anything online talking about GI Joe guns, only mics. There was also a Serpentor in my pile with what appears to be a repro cape. So now I'm worried the whole pile might be full of repros. Any help would be appreciated!
