All the other predator pics I've seen have the normal belsales barrel pin. Your pic looks exactly the same with one section of the barrel removed. The normal barrel pins aren't all that rare and would be easy to modify.
Outside of that have you tried contacting belsales?
Note: While I would love to take credit for his work, I am not associated with Mad Customs!
