There have been several companies in the USA that have made .22 rimfire Gatling Guns. Also, complete plans to make one are available. I have a set of very precise drawings with measurements (plans) to make one and the tripod mount for it.
It used Ruger 10-22 barrels and I know of several of our more competent Members who could construct one. However, all of them, including myself, would rather spend their time doing metalworking on more worthwhile projects, instead of contemplating the metal used in the bars on the window of your "compact residence" provided by the Queen.
