This is an NFA item and is fully transferable. The receiver is rollmarked with the Cobray snake logo and reads "M-11/NINE mm" and "S.W.D. INCORPORATED ATLANTA, GA, U.S.A." Selector markings are "SEMI/SMG" with a separate safety marked "SAFE/FIRE." The operating system is open-bolt blowback with a top-mounted charging handle for straightforward manipulation.
The gun is chambered in 9mm Luger and uses a 5 in barrel with an externally threaded muzzle (thread pitch not specified). Sighting is via fixed iron sights, with a front post and a rear sighting plane integral to the top cover, providing a simple, robust sight picture.
Construction is stamped-and-welded sheet steel with a matte gray/black finish. It is equipped with a hinged steel stock (length of pull 15.0) and a polymer pistol grip. The build reflects the classic 1980s production of SWD Inc., with durable materials and utilitarian features.
A Sten magazine conversion/adaptor is installed, giving the gun a Sten-pattern magazine interface. Included with the sale are a Sten-pattern steel magazine and a Sten magazine loading tool, aligning the package with the conversion for immediate compatibility.
