And from one of America's premier small arms manufacturers we have the Smith & Wesson M76 submachinegun (SMG). Well, not exactly. It?s a little more complicated.

In the 1960s, the peace-loving Swedes blocked the sale of their official SMG, the reliable Carl Gustav M/45, to the U.S. Navy for clandestine ops (SEALS) in Vietnam.

A product of the war years, the Carl Gustav was a blend of earlier design features typical to the German MP40, the British Sten, the Soviet PPSh-41 and the PPS-43.

In the world of arms making, few gun designs are ever truly unique.

Imitation is the ultimate compliment.

Swedish arms maker Gunnar Johnsson designed the Carl Gustav M/45 in 9mm in the 1940s, a weapon that soon became the official SMG of the Swedish Army. Thanks to the Swedish government, the American S&W M76 was born.

If we couldn't buy it, we would have S&W build our own.

The S&W M76 is a blowback, select-fire SMG fired from the open bolt. The pistol grip and magazine housing are welded to the weapon's steel tube receiver that features an ambidextrous safety/fire selector switch. The M76 uses a double-stacked 36-round magazine inserted from below. 9x19 Parabellum are cycled through it at a rate of 720 rounds per minute and shell casings are ejected from the right.

The M76 has a folding steel wire shoulder stock and protected front sight and fixed rear aperture sight. Empty, it weighs slightly more than seven pounds. With the stock folded, the M76 is just 19.5 inches long; with the stock extended, it is 30.5 inches.

The barrel is 7.87 inches and the weapon has an effective range out to 600 feet.

The S&W M76 weighs slightly more than seven pounds, empty. In 1968, S&W developed a version of the M76 that electronically fired case-less ammo. The prototype and the M76 were nearly identical, the exception being the battery housing placed before the trigger guard on the electronic-fire prototype.
