Introduced in 1941, the STEN Gun was a significant deviation from the hand-made, engineered SMGs that were the standard of the interbellum years, constructed primarily from stamped and welded sheet metal and well suited to mass production. Though somewhat rough to the eye, the STEN was the quick and dirty bullet hose that the Allies needed, and were widely issued by the Commonwealth of Nations, air dropped to resistance forces throughout Europe, and imitated by both the Americans and the Germans. Fixed blade front and peep rear sights, with the model and serial number markings on the magazine well and "ENGLAND" on the left rear of the trigger group. The two-position selector is present on the trigger group, with a vented handguard and a tubular buttstock. One magazine is included.
