AVS-36

The AVS-36 (from Avtomaticheskaya Vintovka Simonova 1936 model; Автоматическая винтовка Симонова образца 1936 года) was a Soviet automatic rifle which saw service in the early years of World War II. It was among the early selective fire infantry rifles (capable of both single and full-automatic fire) formally adopted for military service.

The designer, Sergei Simonov, began his work with a gas-operated self-loading rifle in 1930. The first prototype was ready in 1931 and appeared promising, and three years later a trial batch of an improved design was made. In 1935, a competition between Simonov's design and a rifle made by Fedor Tokarev was held. The Simonov rifle emerged as a winner and was accepted into service as the AVS-36. The AVS-36 was a gas-operated rifle with a short piston stroke and vertical sliding locking block. It was capable of both automatic and semi-automatic fire. The barrel was equipped with a large muzzle brake to reduce recoil. Ammunition was in a detachable magazine holding 15 rounds. A knife bayonet was issued with the rifle. A sniper version was produced in small amounts with a PE scope. The AVS-36 was first seen in public in the 1938 May Day parade in Moscow, when it was displayed by the marching 1st Rifle Division. The American public became aware when it was covered in an August 1942 issue of the American Infantry Journal, in an article by John Garrett Underhill, Jr.

Once in service, it quickly became apparent that the AVS was not a satisfactory design; the operating mechanism was overly complicated, and the problem was made worse by the rifle's construction which let dirt get inside the weapon. The rifle was also particular about ammunition quality. The muzzle brake design proved to be a failure &mdash; the rifle was nearly uncontrollable in automatic fire. Some of the problems were traced to the magazine, which was deemed too long. Production of the AVS-36 was terminated in 1938, and a new design competition was held to which Simonov and Tokarev submitted their improved designs.

In 1938 Tokarev's SVT-38 was also adopted for service. In 1939 a politicized dispute erupted within the Soviet elite as to which design, that of Simonov or that of Tokarev, should prevail. Simonov's rifle was lighter and contained fewer parts, while Tokarev's rifle was considered sturdier, although this mainly due to firing pin breakages on Simonov's rifle. Both guns had their supporters and detractors among the Politburo. Stalin ultimately sided with Tokarev, with whom he had a good personal relationship. By a decision of the Defense Committee dated 17 July 1939, mass production was to concentrate on the SVT-38.

Official Soviet production breakdown figures are: 106 made in 1934, 286 in 1935, 10,280 made in 1937, 24,401 in 1938, with an estimated total of 65,800 AVS-36s manufactured until production stopped in 1940 (exact production figures for some years, like 1936 or 1939, is not reported).

The rifle first saw service in the Battle of Halhin Gol, and later in the Winter War, but did not perform well. Some of the problems were caused by incorrect maintenance; many rifles went into combat without having been cleaned of their storage grease, which then "froze" solid. About 300 AVS-36 exemplars were captured by the Finns; some were used by their new owners. The SVT-38s and LS-26s used on the Finnish side suffered from similar problems. After a large amount of the more serviceable SVTs were captured, the AVS-36s were largely withdrawn from service. In the Soviet Union, the AVS was quickly marginalized and apparently withdrawn from service during 1941, though it saw brief service during World War II. Some reports claim that remaining AVSs were mostly scrapped. Today, the AVS-36 is a rare collectors item; most of the remaining rifles in existence are in Finland.

Simonov would later design an anti-tank rifle, the PTRS-41, and the SKS carbine, which employed simpler tilting bolt operation.
