Clear plastic just came in to help clear up the loop hole that airsoft sits in. From my understanding, as long as the gun is clear, it's clear that it's not a gun.
They are quality names, just clear instead of plastic. Then you can look for a metal body somewhere on the forums as people still risk it to bring them in.
That's the short answer.
