with versions of the weapon being produced in Egypt and the United States. Licensed production in Egypt The m/45 has been manufactured under license in Egypt as the Port Said and the Akaba. The tooling needed for production, as well as technical assistance, was sold by Sweden to Egypt during the 1950s. The Port Said looks and functions exactly as the m/45 (first version while the Akaba is a modified and simplified version). The Akaba has no barrel jacket and a slightly shorter barrel and the folding butt stock has been replaced by a telescoping wire butt stock similar to the one used on the US M3A1. The simplified sights of the Akaba were moved to the front (unprotected post) and back (protected peep) of the receiver. Use by the United States in Southeast Asia During the Vietnam War, the US Navy SEALs used the m/45 extensively. One of the gun's qualities which appealed to the US Navy was that the m/45 can fire almost immediately out of the water (over the beach). It also saw use by CIA operatives and advisers. In US service it was largely known as the "Swedish-K" or "K-Rifle". The US Navy was so impressed by the m/45 that when Sweden embargoed the export of weapons to the United States in 1966, Smith & Wesson was given the task of producing a copy. This was designated the Smith & Wesson M76. However, by the time the M76 was ready for combat deployment, the US Navy interest had largely evaporated. Many of the m/45s used by US forces and agencies were devoid of markings, implying clandestine use ("sanitized"). Illegal production in South America In 1975, the Junta de Coordinación Revolucionaria, a Cuban-backed far-left internationalist organization, established a clandestine military factory in Buenos Aires. Although it was easy to produce explosives, there was a severe lack of materials to make firearms. In order to revert this, a Bolivian engineer, nicknamed "Comrade N", aiming to design "a submachine gun with the characteristics of an Uzi, but easier to build and disassemble and using 9mm ammunition" came out with the JCR-1. It was presented by the Argentinian People's Revolutionary Army through its newspaper Estrella Roja as a lightweight and concealable weapon. Approximately 5,000 units were manufactured, though only a few hundred could be assembled until the Argentine Army dismantled the factory in late 1975. Users : ex-Zairan Port Saids
