Genesis and development

The OG-43, designed by Giovanni Oliani in the factory based in Cremona named Società Anonima Revelli Manifattura Armiguerra, was an advanced automatic assault weapon, short ranged, inspired by the maximum economic production and maximum concealment. It is part of a family of weapons produced in emergency situation by the Italian Social Republic, formed by the TZ-45 machine gun, FNAB-43 and Isotta Fraschini. The next version, the OG-44, instead had a more traditional shape. The Ministry of War of the RSI had approved the construction, but it was never initiated as events precipitated.

Description

OG-43 have a very modern line respect contemporary models. Made of pressed steel, charger and magazine also served as a handle.The Bolt in the shape of L flowed, with the recoil spring, in a cylinder above the barrel. This decreased the tipping of the barrel during bursts.The cocking handle flowed above the receiver along the spring-holder cylinder. The stock crutch could be folded inferiorly and forwardly. In front of the trigger guard, underneath the barrel cover hole, it was placed in forwardly reclining wooden handle. The weapon adopted the same magazines two-wire 10, 20, 30 and 40 shots of the Beretta MAB 38. The functioning was short recoil blowback and was shot with bolt open in semi-automatic and automatic mode. The sights were fixed, for 100 and 200 meters.
