Gast gun
Encyclopedia
The Gast Gun was a German
twin barreled machine gun
developed by Karl Gast of Vorwerk und Companie
of Barmen
, and used during the First World War. It was notable for its high rate of fire
of 1,600 rounds per minute and a unique mechanism that is used today in the Gryazev-Shipunov GSh-23L
series of Russian aircraft cannon.
The gun was relatively light at approximately 27 kg (59.5 lb) without ammunition and it was felt that it was highly suited to airborne use. A telescopic sight
was mounted between the two barrels to aid aiming. The weapon was also easy to maintain, and could be field stripped in one minute, thanks to its simple design.
Gast demonstrated the weapon to ordnance experts in August 1917, who were so impressed that a production order for 3,000 guns was awarded to Vorwerk und Companie, along with ten ammunition drums and spare parts for each gun at a unit price of 6,800 marks each. Delivery of the first 100 guns was promised for 1 June 1918, with production ramping up to 500 guns per month by September 1918.
Production of the weapon exceeded these initial projections, and the weapons were received favourably with promises of an order for a further 6,000 guns being promised in September 1918.
A version of the gun firing 13 mm ammunition (13x92mm TuF), the Gast-Flieger MG, was also under development. It used the same ammunition as the Maxim MG TuF and had two curved box magazines.
However, the gun was not widely used, and their existence was kept secret until three years after the Armistice
; it was not until 1921 that the Allied Control Commission became aware of the Gast gun when a cache of 25 of the guns, ammunition and designs was found near Königsberg
. Gast himself had applied for a US Patent in 1920, which was issued in 1923.
A Gast gun was evaluated by the US Army, and found to be reliable and mechanically practical. However it was felt that it did not offer enough of an advantage over the existing machine guns to justify the expense of producing the weapon.
Tromix have recently brought experimented with the design with what they call the "Siamese .223", two M16's rigged together using the Gast firing principle - it is being marketed to US law enforcement.

Description
The weapon uses two barrels combined into a single mechanism in such a way that the recoil from firing one barrel loads and charges the second. Ammunition was fed into the gun from two vertically mounted cylindrical drums, one on each side of the gun. The drums had a capacity of 180 rounds of German 7.92 mm rifle ammunition, which were fed by a compressed spring one by one into the breech. The changing of ammunition drums could be completed in a few seconds by an experienced gunner. The weapon would also fire single shots if there was a problem with one side of the mechanism.The gun was relatively light at approximately 27 kg (59.5 lb) without ammunition and it was felt that it was highly suited to airborne use.

History
The gun, which was to become known as the Gast-Maschinengewehr Modell 1917, was invented by Karl Gast in January 1916 while working for the Vorwerk company, the first weapon being produced in January 1916. Gast took out patents in 21 January 1916 and 13 February 1917, describing his weapon as "a double-barreled machine gun with recoiling barrels". During trials, rates of fire of 1,600 rounds per minute were achieved.Gast demonstrated the weapon to ordnance experts in August 1917, who were so impressed that a production order for 3,000 guns was awarded to Vorwerk und Companie, along with ten ammunition drums and spare parts for each gun at a unit price of 6,800 marks each. Delivery of the first 100 guns was promised for 1 June 1918, with production ramping up to 500 guns per month by September 1918.
