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, perforated heat shield, checkered pistol grip and a side folding buttstock with rubberized covering.

Excellent, with 95% plus original matte gray phosphate finish, showing mild handling marks and spotting overall. The stock is in equal condition, with the pistol grip showing minor scratches. Mechanically needs work; functions fine on safe and semi, action binds up or runs in semi-automatic when put to full auto. 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.
