Developed in 1902, the Madsen was widely adopted, seeing military use as late as the 1970s and being deployed in narcotics-related violence as late as 2013, both in the hands of Brazilian drug cartels and the Brazilian Military Police fighting them. At the onset of hostilities in World War II, the Madsen was the main infantry machine gun in Norway, and would be used by the Nazis as a second-line weapon following the invasion of Norway. This model is configured for anti-aircraft use, with a set of bases at the front and rear of the heat shield (sights absent) that also double as bases for a German-style spring loaded bipod, which is stamped "WaAa15" on multiple parts, and a cone shaped recoil booster on the front. The receiver is configured for belt feeding, with a u-shaped path for the empty belt running over the top cover and a feed mechanism designed to work in conjunction with a specialized box magazine (two included, both green painted steel with leather carry handles). The right side bears Madsen markings and the charging handle, with a 2-position safety switch on the left, wood paneled pistol grip, brown leather sling and a folding buttstock with leather cover. Included with the gun is an extra barrel/breechblock assembly, with a brown leather carrying case.

Very fine with 80% of the Arsenal black finish, showing some light handling marks and scratches. The leather shows some minor scuffs and cracks. Mechanically fine, with one of the magazines having a damaged belt catch spring. NOTE: This item is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives as a Machine Gun.
