In 2012, IWI introduced the Negev NG-7, which is chambered in 7.62×51mm NATO. The NG stands for Next Generation. Both variants of the Negev are in service with the Israel Defense Forces.
The Negev started development in 1985 by Israel Military Industries (now Israel Weapon Industries) to replace the then in service Galil ARM.[5] The Negev entered service with the IDF in 1997, after extensive testing conducted by the IDF Ordnance Corps.[6] The Negev is named after the Negev Desert in southern Israel.

The Negev is a gas-operated, air-cooled, open bolt, select-fire, light machine gun (LMG) with a rotating bolt. The Negev uses a long-stroke gas piston system that runs under the barrel and is connected directly to the bolt carrier, the gas system comes with a three position gas regulator for use with different feed types and conditions.[7] The design was made to be reliable, especially in adverse conditions.[8] It was officially adopted by the Israeli Defense Forces (IDF) in 1997.
The Negev has a quick-change chrome-lined cold hammer forged barrel. The barrel is fitted with a slotted flash suppressor and a folding ambidextrous carry handle, which is used to carry the weapon and remove the barrel of the Negev.[9]
During the weapon's initial development a barrel with a 1 in (25 mm) (1:12 in) rifling twist rate was also planned, adapted for the lightweight M193 cartridge. Additionally, a multifunction muzzle device was designed, used to launch rifle grenades.[10]
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 in 100 m increments. The sight line radius is 440 millimeters (17.3 in).[10] The Negev is equipped with tritium sights for night-time operations, the vials are embedded into the front and rear sights, with a night sight exposed on the rear aperture.
The Negev has its sight rail mounted to the frame of the gun, and not the feed top cover, which is detached when reloading. This allows it to stay zeroed for a longer period of time when mounting red-dot, reflex sights or other optics.[11]
The classic Negev did not possess the modern standardized Picatinny rail, and instead came with a welded adapter for an optical sight. The newer NG-5 and NG-7 have a standard picatinny rail, and in Israel are usually fitted with an optical scope similar to the standard scopes of Israeli assault rifles.
The full size Negev and Negev SF was originally manufactured with a metal-tube, fixed-length, folding (right) stock. This classic tube skeleton stock was a modified stock from the Galil rifle.[14] The design of the Negev's recoil springs and non-reciprocating handle, allow the Negev to fire with the skeleton stock folded; however during reload the bolt cannot be actuated with the stock folded.[14][15]
The Negev NG-5 came fitted with an adjustable length folding stock, that folds to the opposite direction to allow complete operation of the gun with the stock folded, with cheek well adjustment, allowing for easier fitting.[15][13]
Every variant of the Negev can have a folding bipod, installed to the forward end of the handguard and folded under and becoming part of the handguard when stowed. The receiver also has slots and hooks used to secure the weapon to vehicle mounting hardware, including helicopters.[11][14]
The Negev SF 'Commando' variants also come with a 45 degree forward grip "assault handle", allowing controlled fire while not using the bipod. The assault grip and bipod can be installed together, however the bipod cannot be folded with the assault grip installed.[16][17]
The classic Negev could be fitted with mounting hardware on the handguard to allow users to mount a laser pointer.[11] Current Negev models come mounting positions for bipods and the "assault grip" as well as a number of picatinny rails, including on the handguard allowing users to mount other hardware, including: laser pointers or laser target and illumination devices.[16][15]
The standard Negev is chambered in 5.56×45mm NATO, optimized for the SS109 cartridge. The Negev NG-7 and 7 ULMG variants are chambered in 7.62×51mm NATO.
The Negev feeds from an M27 disintegrating, open-link ammunition belt, carried in a 150-round fabric container that clips into the magazine well, or alternatively from a 35-round box magazine from the Galil assault rifle, or a 30-round STANAG magazine from the M16 rifle (with the use of an adapter). 200-round ammunition belt containers are also available. Belted ammunition is introduced into the feed tray port from the left side, while the magazine is inserted vertically into the magazine well at the base of the receiver.
The feed system, which loosely copies the Czechoslovakian Vz. 52[7] and the PK, uses a lever mounted on the left wall of the receiver and driven by a cam in the recoiling bolt carrier to turn a small feed pawl. The belt is pushed by the pawl only during the rearward movement of the bolt carrier.
The Negev 7 ULMG and ULMG SF, can be converted to 6.5mm Creedmoor cartridge by changing barrels; and feed from standard M13 disintegrating links.[18]
