QBR-55

The QBR-55 is a pump action long ranged 20 gauge shotgun built by the Quantonian Empire, The QBR-55 is designed to be an anti tank shotgun for troopers who get close enough to an enemy tank and blast it which then penetrates the armor and kill the crew inside. The 20 Gauge AT Shells that the QBR-55 uses were specifically designed for that shotgun as each shell contains 10000 half a millimeter wide Quantasium Steel ball bearings. If fired correctly a single shot from the QBR-55 can kill an entire tank crew.
The QBR-55 is also perfect for taking out enemy infantry.
The QBR-55 uses a tube loading mechanism.
Depending on the speed of the users arm whilst using the pump handle they can make the shotgun almost fully automatic.
