The Mondragón Rifle is a Mexican battle rifle that holds the distinction of being the world's first automatic rifle, and the first fully automatic firearm that could be operated by a single man. The weapon was first deployed by the Mexican Army in 1887, and later saw use by Germany in the First World War and various Chinese factions in World War II and Chinese Civil War. The rifle was fed by an 8 or 20-round magazine, and fired at a rate of fire of 750-1400 rpm. The weapon fired a 7.5mm Mauser round at a range of up to 550 meters. The weapon was accurate in semi-automatic fire, but less so in full auto, proving effective only at closer ranges and for suppressive fire. The weapon could resist sand and dirt well, but would malfunction with moisture.
