The Samozaryadnaya Vintovka Tokareva 40 is a Soviet semi-automatic rifle that proceeded from the SVT-38. When issued as a sniper rifle, it generally uses the PU scope.
A more robust version, the SVT40 shown here, was characterized by the removal of the earlier rifle's externally mounted cleaning rod, which was mounted instead, as per convention, beneath the barrel.
On the SVT40 it was of wrap-around type as opposed to the metal and wood forward guard of the SVT38.
These Japanese weapons, supplemented substantially by Sovietweapons like the PPSh M-1941 7.62mm submachine gun (burp gun), and semi-automatic rifles like the Tokarev SVT40 shown here, were among the more commonly used weapons by the CCF during the first several months of the war.
The problems encounted by these rifles centered on their durability, the SVT40 is an improved version of an earlier Tokarev design the SVT38.
Although the SVT40 was made more robust than the earlier weapons it was still found to require more care than the typical Soviet soldier would give to their weapon.
The ability to get a rapid second shot was seen as an asset to snipers and generally they took better care of their weapons.
