The Samozaryadnaya Vintovka Tokareva, Obrazets 1940 goda ("Tokarev Self-loading Rifle, Model of 1940", Russian: Самозарядная винтовка Токарева, образец 1940 года) or SVT-40 is a Soviet semi-automatic battle rifle. The SVT-40 saw widespread service during and after World War II. Intended to be the new service rifle of the Soviet Red Army, production was disrupted by the German invasion in 1941 resulting in a change back to the older Mosin–Nagant bolt-action rifle for the duration of WWII.
