This Machine Gun became very successful and still until today the Ksp m/1914 remains on the Machine Gun medals of the Swedish army.

When the author made his army service you could choose to shoot with either the MMG water-cooled Browning Ksp m/36 or the FN MAG ksp 58. It was much easier to win the medal by using Ksp m/36.

The machinegun is unusual because it is the only successful military machine gun working on the delayed blowback system before H&K systems at 1950.

Mechanism (private collection)

The machine gun has got its name after its constructor Andreas Wilhelm Schwarzlose (1867-1936) who lived in Charlottenberg, Germany. It was first produced by Steyer in Austria 1902.

The machine gun has a small number of moving parts and a fixed barrel. It saw service during both the Great War and WW2.

This is a water cooled Medium Machine Gun (MMG).

The Schwarzlose Machine Gun M1907 was an extremely simple mechanism compared to other famous designs like Maxims. It was easy to make and proved reliable. The designer had managed to solve the problem with a delayed blowback system. The problem is that the breech starts moving backwards immediately as the cartridge is fired. The gas pressure is still very high and the walls of the cartridge case are expanded towards the chamber, which will cause very high friction. At the same time the extractor starts pulling out the empty cartridge case. The problem was solved by using very strong recoil springs and recoil parts together with a very short barrel. When the bullet left the barrel the pressure dropped while the kinetic energy of the recoil parts continued to pull out the empty cartridge case and reload the gun. The Schwarzlose machine gun has a device for oiling each cartridge to ease the reloading cycle. On each stroke oil was squirted into the firing chamber to lubricate the incoming cartridge case.

1912 some changes were made to the feed system and this change was called M1907/12. It had a straight top receiver and a simplified oil pad system instead of the pump mechanism.


This m/14 above was made 1930 by Carl Gustaf Stads Gun Factory.

This MMG m/14 was one of the last made Schwarzlose. The year of production (1930) can clearly be seen close to the handles.



The Schwarzlose Machine Gun was made under license in Sweden (and Netherlands). The construction proved to be a remarkably successful machine gun.

Carl Gustafs Stadts Gevarsfaktori in Eskilstuna Sweden produced about 1 300 Schwarzlose machine guns. Browning designs replaced m/14. However the Schwarzlose tripod m/14 remained until about 1980.

Tripod m/1914

The Schwarzlose Machine Gun was put on top of a compact tripod with locking bars to prevent the MG from collapsing.


The elevation is controlled by a wheel acting on a toothed quadrant.

By this construction it is just to move the rear of the MMG laterally over a sector plate.

The tripod could be released to allow the mount to lie directly on the ground with the centre line of the bore being just less than 0,3 m above the ground. This tripod was also called m/1914 in Sweden.

It was a very simple and sound construction, so it became the platform for later Swedish Medium Machine Guns like m/14-29 and m/36.

Kulspruta m/14-29

Kulspruta m/14-29 is NOT a Schwarzlose Machine Gun!

The Ksp m/14-29 is a water cooled Browning M1917 equipped in Sweden with a water cooling jacket from the Schwarzlose MMG Ksp m/14.
he MMG Ksp m/14-29 has also inherited the tripod.

The calibre was 6.5 mm.

It was used by the heavy Infantry Support Platoons contrary to the light Infantry Platoons. These Support Platoons were equipped with heavier weapons like this MMG Ksp m/14-29 and with 8 cm trench mortars.

The Ksp m/14-29 was replaced by the Browning Ksp m/36, which you can read more about here>>>



Closest to camera you can see MMG Ksp m/14-29; in the middle Ksp m/1914; and at the rear Ksp m/36
