IMI Negev
The Negev is an Israeli 5.56 mm and 7.62 mm light machine gun, developed by Israel Military Industries Ltd. (IMI) of Ramat HaSharon (now Israel Weapon Industries), as a replacement for the 5.56 mm Galil ARM light machine gun, whose barrel would overheat easily during sustained fire. Design work on this new indigenous firearm began in 1985, it was inspired by the Belgian FN Minimi,〔James H. Willbanks, 2004.〕 and it was officially adopted by the Israeli Defense Forces (IDF) in 1997. In 2012, IWI introduced the new Negev NG7, in 7.62mm calibre, to become the standard issue for the IDF. ==Design details==
The Negev is a gas-operated selective fire firearm that uses propellant gases from the barrel to cycle a short-stroke gas piston operating system under the barrel and a rotary bolt locking mechanism. The bolt itself features 4 radial locking lugs that engage the barrel extension and its rotation is controlled by a pin on the bolt body, which rides inside a camming guide machined into the bolt carrier. The bolt contains a spring-powered casing extractor unit, while a lever ejector is housed inside the receiver (it is rotated by the recoiling bolt carrier).
