well. One more attempt. So, this is Notachi. 5 charged DAO revolver. Linear trigger, CAM operated cylinder with parking position between chambers. Hammer with rebound utilizing two tension springs. Top breaking frame, but loading/unloading by one round a time. This because of internal sub-frame. By design the internal sub-frame is two 8mm steel plates braced with three 5mm bolts. Chiappa Rhino grips compatible.

I just post it on the Odysee, but should warn: THIS IS not tested, and should not be used with live ammo. This is mainly proof of concept, and posted only for engineering researches purpose. You’ve been warned. https://odysee.com/@clearview4851:e/notachi-rc1:9
