OK after a closer look at the pic I can say the guns ARE real. There's a Ruger .22 and a Glock. He's holding a .45, most likely a RIA. It's hard to tell the revolvers at the angle taken but they have the look of real.
There is ammo and extra mags laying around that fit with the guns and the noted speedloader.
I have no clue WTF the plastic in question is though. You guys might be on the right track.
