The IWI Negev NG-7 is a 7.62×51mm NATO general-purpose machine gun (GPMG) developed by the Israeli firearm manufacturer, Israel Weapon Industries (IWI) (formerly Israel Military Industries Ltd (IMI) of Ramat HaSharon). It has a barrel length of 508 mm (20 inch) and two operation modes; semi-automatic for accurate and fast controlled fire, and fully automatic for maximum firepower. The NG-7 is based on the reliable NEGEV 5.56 LMG (NG-5) and it is the only Light Machine Gun 7.62X51mm with a semi-automatic mode, empowering its safe use in Close Quarter Battle (CQB) as well.
Although it is chambered in greater caliber, both the NG-7 and the NG-5 are almost identical in size and weight. The IWI Negev NG-7 SF is a compact variant of the Negev NG-7. It uses a shorter barrel and is primarily fitted with a side grip (Negev Assault Grip).
The IWI Negev is a gas-operated selective fire light machine gun 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). The design was meant to be reliable, especially in adverse conditions. The Negev is striker-fired, where the bolt carrier assembly acts as the striker, and fires from an open bolt position. The weapon can be secured safe regardless of the position of the bolt carrier group. The cocking handle is equipped with a ratcheting mechanism that immobilizes the partially cocked bolt carrier.
The Negev has a quick-change chrome-lined barrel that is manufactured using a cold hammer forging process. The barrel is fitted with a slotted flash suppressor and a fixed carry handle, which is used to transport the weapon and change-out an overheated barrel. The barrel can be changed only after lifting open the feed tray cover. Additionally, a multifunction muzzle device was designed, used to launch rifle grenades. The Negev’s iron sights (closed-type) consist of a front post (adjustable for both windage and elevation) and a rear aperture sight with an elevation adjustment drum, with 300 to 1,000 m range settings. The barrel can also be optionally fitted with mounting hardware that would allow the Negev to mount a laser pointer or reflex sight. The machine gun has a metal side-folding (right side) stock and a removable bipod, installed to the forward end of the handguard and folded under the handguard when stowed. The receiver also has slots and hooks used to secure the weapon to vehicle mounting hardware.
