A closed-bolt blowback-operated submachine gun, the Reising Model 50 saw action with the U.S. Marines in the Pacific as a substitute for the M1 Thompson, though they found their best success as defensive weapons for war-essential industries and as patrol carbines for American police forces. Blade front and elevation adjustable peep rear sights, with a flash hider/muzzle break, cooling fins on the barrel, three-line New Haven address near the ejector port, and three-position selector/safety on the right side. Smooth pistol grip stock with a cocking lever on the underside, a tan canvas sling, and a lightly ribbed buttplate.

Very fine as professionally refinished, showing 95% of a dark parkerized finish, with some light handling marks and minor loss of detail in the markings. The stock is also very fine, with a few dents and scuffs. Mechanically excellent.
