AVS-36: full disassembly & assembly

The AVS-36 (Avtomaticheskaya vintovka Simonova obraztsa 1936 goda "Automatic rifle Simonov model 1936" Russian: Автоматическая винтовка Симонова образца 1936 года (АВС-36)) was a Soviet rifle which saw service in the early years of World War II.

The designer, Sergei Simonov, began his work on a gas-operated self-loading rifle in 1930. The first prototype was ready in 1931 and appeared promising. 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 the winner and was accepted into service as the AVS-36. 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 of it when it was covered in the August 1942 issue of the American Infantry Journal, in an article by John Garrett Underhill Jr.

The AVS-36 was a gas-operated rifle with a short piston stroke and vertical sliding locking block with secondary locking flappers, each of different size. The barrel was equipped with a large muzzle brake to reduce recoil. Ammunition was in a detachable box magazine holding 15 rounds.
