Ammo Chain. It's really easy to make. Grab 3 U-Clips in Gunmetal or Black and break one of the ends of one of them and stick that in the slot where the Ammo Box was in. Then add a Ammo Clip(Obtained from a Minigun) and add another U-Clip. You can make it as long as you want. As long as you got enough U-Clips and Ammo Clips. Oh, and one thing: Also sand the U-Clip a bit.
