Designed by Sergei Simonov in 1938, the PTRS-41 (Simonov Anti-Tank Rifle) was manufactured throughout World War II between 1941-1945 and uses the same 14.5x114mm round as the PTRD-41 bolt-action anti-tank rifle, but with a magazine-fed semi-automatic action. Although tank armor advanced rapidly throughout World War II, one of the most famous incidents involving successful use of the PTRS-41 was during the Battle of Stalingrad in which one was positioned on the roof of a fortified apartment building that Red Army defenders held for 60 days between September 27th-November 25th, 1942 against the Wehrmacht offensive; the PTRS-41, aiming downward, ambushed numerous unsuspecting German tanks from above, knowing that the tanks were unable to elevate their weapons enough to shoot back, and penetrated their thin turret-roof armor causing massive damage to the crews inside. The PTRS-41 platform found a second life in the form of the SKS semi-automatic rifle, which took the PTRS-41 action and scaled it down to a shoulder arm chambered for use with the 7.62x39mm cartridge. This rifle features a large disc-shaped muzzle brake mounted to the blued barrel, hooded pin front and tangent rear sight, swiveling bipod, a hinged cover that opens from the bottom for loading with a five-round en bloc clip, a smooth wood pistol grip, and a wood club foot buttstock with multi-layered recoil pad. The right of the buttstock is marked with the Russian Izhmash factory mark consisting of an arrow inside of a triangle.
