The PTRD-41 is a Soviet single-shot, bolt actionanti-materiel rifle chambered for 14.5×114mm cartridge. The weapon was designed by Vasily Degtyaryov as an easily-produced variant of the PTRS-41, its production were started in 1941.
Extremely crude in design, the PTRD is made out of nothing more than a long metal barrel with a simple trigger mechanism. It was extensively used by the Soviet Red Army during the World War II. It is notably the gun used by Suou Pavlichenko in Darker than Black.
