The Rexim Favor submachine gun was developed in the early 1950s by the Swiss company Rexim S.A. Some sources claim that in fact this weapon was designed in France, but its plans were stolen from French MAT factory and carried over to Switzerland. Production of this weapon was contracted to the Spanish company La Coruna, although all sales were handled by the Swiss company. About 5 thousands of these submachine guns were manufactured between 1955 and 1957, but due to the lack of sales Rexim company went bankrupt. During 1960s, at least some of these submachine guns ended up in Turkey, being used by Turkish army. Overall, this weapon was overly complicated, and despite being offered in many versions, it found no takers except the already mentioned Turkish military.

The Rexim Favor submachine gun is a simple blowback weapon that fires from closed bolt. It has a separate annular striker which is operated by separate spring of large diameter, that is located around the bolt return spring. Gun fires in single shots or full automatic, thanks to the fire mode selector located above the front of the trigger guard on the right side of the gun. One noticeable feature of the Rexim Favor submachine gun is that its barrel can be easily removed by unscrewing the barrel nut and pulling the barrel forward. Several barrel lenghts were offered with this machine gun, with or without ventilated barrel shroud and muzzle compensator. Feed was from detachable double-stack box magazines with single feed position. Standard sights were adjustable for range from 50 to 500 meters. Guns were offered with skeletonized, side-folding metallic buttstocks or with solid wooden buttstocks. Another unusual feature of the Rexim Favor guns was the integral spike bayonet, which was carried below the barrel and pointing to the rear when not required, and re-installed pointing forward when the hand-to-hand combat was imminent.
