Frolov Shotgun
These bolt-action shotguns, nicknamed “Frolovka” , are conversions of Mosin Nagant rifles into hunting shotguns, designed by engineer Pyotr Nikolaevich Frolov and manufactured in the 1920’s at TOZ. A surplus of Mosin Nagant rifles, most heavily battered during World War I and the Russian Civil War, were converted into 20 - 32 gauge shotguns. Such a measure allowed to quickly cover the lack of cheap hunting shotguns in Soviet Russia.
