This U.S. inspected Remington Model 31 riot shotgun was manufactured in June of 1942, one of a reported 8,992 delivered on U.S. government contract between 1940-1944. These shotguns were used mostly for security duties and gunnery training, with some evidence that at least a few Model 31s saw combat use during the war. At the outbreak of World War II, Remington diverted most of its Model 31 shotgun production in order to manufacture M1903 bolt action rifles, while also concentrating its efforts on manufacturing Model 11 autoloading shotguns for military use, leading to the relative scarcity of U.S. contract Model 31 shotguns. The left of the receiver is roll stamped with the Remington name, model and serial number above the "U.S. PROPERTY" marking, and a small flaming bomb ordnance inspection cartouche is stamped on the left of the buttstock. The top of the barrel is roll stamped with the two-line Remington Arms address and patent dates, with the left marked "12 GA. FOR 2 3/4 OR SHORTER SHELLS." ahead of "CYL". The lower left of the barrel is stamped with the matching serial number ahead of the date code "PL" (June 1942). It has a bead front sight and raised solid matte rib on top of the receiver (only). Fitted with a thirty groove pump handle, pistol grip walnut stock and bakelite Remington serrated buttplate.
