After searching everywhere for this and not finding it i ripped it myself from the game and gave it a clean up which was not easy if anyone else would know if they tried ripping guns from the game.
Anyone is welcome to clean this up and re-mesh it for better poly count or slice it for printing but please link it back here for others :D
