SVT-40
The SVT-40 (Russian: Самозарядная винтовка Токарева, образец 1940 года, romanized: Samozaryadnaya vintovka Tokareva, obrazets 1940 goda, lit. 'Tokarev's self-loading rifle, model of 1940') is a semi-automatic battle rifle developed in the Soviet Union that saw widespread service during and after World War II. It was intended to be the new service rifle of the Soviet Red Army. However, its production was disrupted by the Axis invasion in 1941, resulting in a change back to the Mosin–Nagant rifle for the duration of the war, although both rifles served concurrently.
In the early 1930s, the Soviet Union requested the development of a semi-automatic rifle to replace the Mosin-Nagant, taking inspiration from the Mexican Mondragón rifle. The design was left up to two individuals, Sergei Simonov and Fedor Tokarev. Simonov, who had experience in developing the Fedorov Avtomat, created a prototype for the AVS-36 in 1931. The rifle was used during the Winter War but was removed from service in 1941 due to design flaws.
In 1938, Tokarev's rifle was accepted for production, under the designation SVT-38 with hopes that it would become the new standard-issue rifle of the Red Army. Ambitious production plans anticipated two million rifles per year by 1942. Production began at Tula Arsenal in July 1939 (production at Izhmash began in late 1939).
The SVT-38 is a gas-operated rifle with a short-stroke, spring-loaded piston above the barrel and a tilting bolt, a system that would later be used in the FN FAL. The SVT-38 was equipped with a bayonet and a 10-round detachable magazine. The receiver was open-top, which enabled reloading of the magazine using five-round Mosin–Nagant stripper clips. The sniper variant had an additional locking notch for a see-through scope mount and was equipped with a 3.5×21 PU telescopic sight.
The SVT-38 saw its combat debut in the 1939–1940 Winter War with Finland. The rifle had many design flaws, as its gas port was prone to fouling, the magazine would sometimes fall out during use, and it was inaccurate, only being effective up to 600m. Production of the SVT-38 was terminated in April 1940 after some 150,000 examples had been manufactured.
With the removal of the SVT-38 from service, an improved design, the SVT-40, entered production. It was a more refined, lighter design incorporating a folding magazine release and lightening cuts. The hand guard was now of one-piece construction and the cleaning rod was housed under the barrel. Other changes were made to simplify manufacturing. Production of the improved version began in July 1940 at Tula and later at factories in Izhevsk and Podolsk. Production of the Mosin–Nagant M1891/30 bolt-action rifle continued, and it remained the standard-issue rifle to Red Army troops, with the SVT-40 more often issued to non-commissioned officers[citation needed] and elite units like the naval infantry. Since these factories already had experience manufacturing the SVT-38, output increased quickly and an estimated 70,000 SVT-40s were produced in 1940.
By the time of Operation Barbarossa, the Axis invasion of the USSR in June 1941, the SVT-40 was already in widespread use by the Red Army. In a Soviet infantry division's table of organization and equipment, one-third of rifles were supposed to be SVTs, though in practice they seldom achieved this ratio. The first months of the war were disastrous for the Soviet Union; they lost hundreds of thousands of SVT-40s. To make up for this, the production of the Mosin–Nagant rifles was reintroduced. In contrast, the SVT was more difficult to manufacture, and troops with only rudimentary training had difficulty maintaining it. Submachine guns like the PPSh-41 had proven their value as simple, cheap, and effective weapons to supplement infantry firepower. This led to a gradual decline in SVT production. In 1941, over one million SVTs were produced but in 1942 Izhevsk arsenal was ordered to cease SVT production and switch back to the Mosin–Nagant 91/30. Only 264,000 SVTs were manufactured in 1942 and production continued to diminish until the order to cease production was finally given in January 1945. Total production of the SVT-38/40 was around 1,600,000 rifles, of which 51,710 were the SVT-40 sniper variant.
SVTs frequently suffered from vertical shot dispersion; the army reported that the rifles were of "flimsy construction and there were difficulties experienced in their repair and maintenance". The stock, made of Arctic Birch, was prone to cracking in the wrist from recoil. This was generally remedied by drilling and inserting one or two large industrial bolts horizontally into the stock just before the wrist meets the receiver. [citation needed] Many rifles were also poorly seated in their stocks, letting the receiver shift on firing. This led to a field modification that selectively shimmed the stock with birch chips, usually around the receiver and in between where the wood stock meets the lower metal handguard.[citation needed] For a sniper rifle, this was unacceptable and production of the specialized sniper variant of the SVT was terminated in 1942. Milling scope rails in the receivers of standard SVT rifles was also discontinued. Other production changes included a new, simpler muzzle brake design with two vents per-side instead of the six on the original.
