We have seen kits that allow you to convert your Action Army AAP-01 GBB Pistol into the weapons seen in the Gundam series. In this video PlaSSo shows how he made his own Gundam Beam Magnum using 3D Printing to build a kit for the AAP-01. The Beam Magnum is a powerful handheld gun used by the RX-0 series mobile suits. It fires beams that are hotter than the sun and can destroy a mobile armor with one shot. However, it uses up a lot of energy and has limited ammo, so it is not good for long battles or situations that require less force. The gun can be attached to the backpack when not in use.
