That time Smith & Wesson went Swedish: The M76 sub gun (VIDEO)

Although U.S. special ops types really dug a certain zippy Scandinavian SMG in Vietnam, the Swedes weren’t playing ball.

The classic “Swedish K” or Kulsprutepistol m/45 — a very basic 9mm designed during WWII that ended up being popular for generations — saw use by Navy SEALs and Army Special Forces types in the early days of the Vietnam conflict.

A straight-blowback action weapon that fired from an open bolt, it hummed out NATO standard 9x19mm rounds from a 36-round Suomi-style stick mag at a controllable 600-round per minute cyclic rate.

The problem was, as explained in the above piece from American Rifleman, once the special warfare guys got hooked on them, Stockholm pulled the plug in 1966, leaving Smith & Wesson to pick up the slack. Thus, the M76 became a thing.
