Seen on Vimeo is a video showing a Revolving Shotgun Airsoft Prototype. This looks a prototype done with 3D printing by Pancake Ayaka and you can load up to 6 shotgun shells at any given time. We are not sure if this uses the APS shotgun shells which you load up with C02 as propellant. A test shoot is included in the footage and we don't know if it will be taken to another level, making a production version.
