He probably photoshopped himself into the pic. Even taking the different angles into consideration, the head on the right looks too narrow...like the width-to-length ratio is off.
What I wanna know is: why didn't he take a black marker and color the orange end of his "gun"?
Yes, I realize it is some version of an AirSoft pistol, and yes, I'm fully aware of the legal requirements for having that plainly visible orange addition. But if you'll note, my question was why the OP didn't color the orange tip black for that picture to make it less obvious.
