Ok, from an NFA perspective, I know that Gatling style guns are no different than any semi auto, and they used to be considered cash and carry firearms in MD, same as a single shot rifle. With the ban on rapid fire trigger devices, however, I'm not sure where these fit. The ban included trigger crank devices. Strictly speaking a Gatling gun doesn't use a trigger crank (ie a crank that externally attaches to a trigger), it uses a crank trigger (ie the crank is the trigger mechanism). Does anyone know if these are still legal in the "free State" of Maryland?
