Originally manufactured by Smith & Wesson as the Model 76, which in turn was designed to fill the same niche as the Gustaf M/45 "Swedish K" SMG, the MK Arms MK760 is a lightweight and agile weapon for close quarters fighting, and in the initial S&W incarnation was a go-to weapon for the American special warfare community in Vietnam. Brought to market in 1983, the passage of the 1986 Firearm Owners Protection Act killed the both the 760 and MK Arms in general, resulting in a very limited window of transferable production. Protected post front and notch rear sights, with the MK Arms markings on the magazine well, a combination barrel nut and ventilated heat shield, ambidextrous "SAFE"/"SEMI"/"FULL" selector, side folding buttstock, and a checkered pistol grip.

Excellent, with 97% plus original matte gray finish, showing some light scratches and handling marks overall. A few dings are present on the pistol grip. Mechanically excellent. 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 478.
