Type-31 Anti-Infantry Burst Gun

The, called the Fuel Rod , is a weapon used by the USR.

Description
The Fuel Rod Burster is a unique USR shotgun. Using five barrels, the Burster launches small Fuel Rods from each at the same time, the resulting shot being very deadly, penetrating even heavy armor in a concentrated blast. Due to size constraints, only three extra Fuel Rods can be stored in the barrels at a time, so the gun must be reloaded every five shots.
