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.
