Our Assessment: This is a Stevens-Savage M520-30 Riot Gun made between 1942-1944. Like most WWII era shotguns, the Stevens 520 series and 620 series were made for the war effort in order to fill various roles including front-line combat, police and patrolling, and for Aerial gunnery training to hone the skills of defensive gunners in use in the various light, medium, and heavy bombers being fielded by the U.S. Army Air Corps./Army Air Force and U.S. Navy. Total wartime production of all Model 520-30 shotguns was approximately 35,000, though the split between the three variations is not known. These guns, like many of the other various combat shotguns in use by the U.S. Military, soldiered on into the Korean War as well as the Vietnam War, as well as serving faithfully in various Law Enforcement agencies in the post-war years. This Model M520-30 has a matching barrel assembly and receiver and this gun is in Fine condition retaining approximately 93% of its metal finish and has a bright bore with no erosion, though there is some fouling. This would make a nice addition to a US Military shotgun collection and would still serve as a good defensive shotgun to this day. Please see our photos and good luck!
