Originally developed in the late 1960s, the S&W Model 76 was designed to fill the niche of a lightweight and compact 9mm SMG after the American special forces community was cut off from sources of the Carl Gustaf M45 "Swedish K" SMG; the Swedish government, neutral in the Vietnam War, was uncomfortable with their exports being used in the conflict. Fixed blade and peep sights on the tubular receiver, with an ambidextrous "FULL"/"SEMI"/"SAFE" selector switch, checkered pistol grip and a side folding buttstock with rubberized covering. With two extra magazines, green canvas magazine pouch, and a rubberized case for a spare machine gun barrel.

Excellent, with 97% of the original matte gray phosphate finish, showing some mild handling marks and a small amount of spotting. Some light scuffs and scratches are present on the grip and stock cover. The disconnector occasionally engages during full-auto cycling, otherwise mechanically fine. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 479.
