The Anti-barrier revolver shotgun is a weapon produced by Academy City. It's a powerful shotgun capable of punching through a tank with a single shot or forcing open the door of a nuclear shelter with a few shots at close range. The barrel can hold up to the explosive force of the gunpowder by delicately controlling the type and arrangement of the gunpowder. The direction of the explosive force can be controlled so that the lowest possible amount of damage is given to the barrel and the greatest possible amount of destructive force is released. It can also suppress riots by using blanks that create powerful shockwaves and can alternate between the two types of ammunition by switching between its cylinder chambers.

While it's the standard weapon of HsPS-15 Powered Suits, it has been seen in use by other individuals in Academy City, including an Anti-Skill member wielding a prototype version of it during the AIM Burst incident and the leader of MAR, Therestina Kihara Lifeline, wielding one with her personal powered suit.
