     This was the last Gatling model chambered for 11.63×53.3mmR (45-70) purchased by the US Army. It is an improved version of the Model 1883 with the brass casing around the barrels having been removed to save on manufacturing difficulties and costs. The feed system was set up so that the weapon could be loaded with either the standard 40-round feed cases, or a Bruce Feed could be inserted into the magazine well and it be used to load the weapon from 20-round boxes.
