Soviet M91/59

This handy little carbine was originally built as a 1943 Tula 91/30 rifle, but was later shortened by the Soviets to make a rifle that's rather similar to the M38/M44 family of carbines. Note the 91/30 rear site has been altered (goes out to 1000 meters, as opposed to the 91/30 sight which originally went to 2000 meters), but not removed.
