The Reising was an American submachine gun manufactured by Harrington & Richardson. It was designed and patented by Eugene Reising in 1940. The two primary versions of the weapon produced during World War II were the M50 and the simplified folding stock M55. Over 100,000 guns were ordered, and were initially used by the United States Marine Corps.
This weapon runs smoothly and has the original military sling and two 20 round mags.
