It is directly built off of the U-94 Rapidfire, however when picked up it says 'Bullet Box'. It has unlimited ammo, and fires as fast as the DJW Destroyer. It also does as much damage as the Harringer A7, therefore being able to kill a Commander in 4 shots, and a Colonel in 5. It can be found under the Sector 2 staircase at Joseph's Shack.
- It, like the U-94 Rapidfire, is based off of the Ingram Mac-10.
