That looks an awful lot like a Paranorman Phantom Pack... The giveaway is the gun mount box located by the HGA and the "caps" on the cylinders located on the cosmetic plating. I've owned one of Norm's packs a while back and I'm pretty familiar with its construction and parts.
I don't mean to start any trouble, but if that's one of Norm's packs, then Norm should be recognized for his work.
