As stated in the title, I saw the video by TFBTV about their shoulder fired, battery powered, 22LR Gatling Gun and I think this would be one of the coolest projects ever if anyone would tackle this for the 3D2A community, even if it was locked behind the SOT licensing.
Need an SOT FFL (Special Occupational taxpayer) to build it. It’s a machine gun. It would be an interesting challenge to make something similar with an frt. The trigger would somehow need to turn the crank.
Sounds doable, essentially a revolver action in a gatling gun that indexes the barrels when the trigger is pulled.
The question is how do you add an FRT component that resets the trigger in a traditional gatling design?
That certainly puts up a challenge, as I stated above it would be cool if someone made one or the other, FRT is obviously better for the general 2A hobbyist, but even if someone made an SOT version and released the files with warnings of “for SOT’s only.” Perhaps for the FRT version you have a “grip safety” type button that runs the rotating barrels at a fixed speed, and a trigger linked to the bolts so as the bolts move back and forth chambering cartridges it forces the trigger forward and backwards.
