Not entirely sure if this is an actual official APS product since the post is from a third-party site, but APS reposted it and it seems "legit". The post says January 2024 release date. I would assume it takes APS CAM 870 shells, even though the post states "12 gauge".
Seems like it's a mechanical rotating drum that uses the trigger and springs to rotate the magazine shells. I would have preferred a Kel-Tec KSG but this seems kinda cool too
