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

This thing designed for centerfire cartridges, I’m even not sure, if the hammer strike force will be enough for rimfired. Anyway, it is excessively large for .22. It designed for 13mm OD liners, that’s why the cylinder is so big.
If someone will redesign it for .22 - always welcome. But I strongly recommend to do it ONLY for high-skilled person. It is very experimental thing.
