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 brake, 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 canvas sling, and a ribbed plastic buttplate with H&H imprint. Two magazines total (one unmarked extended, one H&R marked in standard length) are included, along with three books: H&R Reising Submachine Gun Manual (Desert Publications 1993), The Reising Submachine Gun Story by Iannamico, and Reising Do Everything Manual by Pugliese.

Very fine, with 95% of the refurbished matte gray parkerized finish, showing some light pitting under the finish, handling marks and edge wear. One of the ribs is broken out and absent from the muzzle device, and the magazine well and trigger guard show mild pitting. The stock is very good, with some splitting around the front sling swivel and between the magazine well and trigger, and internal repairs in the latter area. Mechanically very good.
