Louis Schmeisser, chief small arms designer of the Bergmann Industriewerke  company in Suhl, Germany, began to develop machine guns for Bergmann in around 1900. Bergmann announced his first working machine gun in 1901, and Schmeisser kept improving these for a decade and a half. Bergmann-Schmeisser machine guns were lighter and more compact, as well as more simple designs than the Maxim guns; however, the heavier Maxims were found to be more durable, and before the war the German army showed little interest in Bergmann guns. When, in 1915, a need arose for a light machine gun, Schmeisser developed his last water-cooled gun into an air cooled, belt fed weapon, known as the Bergmann Model 1915. This gun fired from an open bolt, and during trials showed poor reliability. Recognizing the flaws, Schmeisser quickly redesigned this gun to fire from a closed bolt made some other improvements, and this became the Bergmann Model 1915 n.A. (neue Art – new model) machine gun. Starting in 1916, the MG15 n.A. was issued in limited numbers to German troops in the field. The Bergmann MG 15 n.A. machine guns were put out of production in 1918, with the end of the Great War.

 

The Bergmann MG 15 n.A. machine gun is a short-recoil operated, air cooled, belt fed weapon. The finned barrel is enclosed within a tubular jacket with cooling slots. The bolt is locked using a vertically moving locking-block located within the barrel extension. When forced down by cams in the receiver, the locking block engages cuts made on the top surface of the bolt, securely locking it to the barrel extension. Upon recoil, the locking block is forced up by the cams in the receiver, thus unlocking the bolt. A lever-type bolt accelerator was provided for improved reliability.

The MG 15 n.A. fires from a closed bolt, and in automatic mode only. The firing mechanism is of the hammer type, and a manual safety is located at the right side of the receiver.

The MG 15 n.A. uses non-disintegrating cloth belts compatible with Maxim-type MG 08 guns, or proprietary metallic belts. The feed is of the two-stage type. The belt-feed unit is operated by the recoiling barrel through a set of levers and springs.

MG 15 n.A. can be used either from a MG 08/15 bipod, or from a light tripod mount
