IWI Tavor is the new supergun made in Israel and intended to replace the M4 carbine. Given the problems experienced by some bullpup designs – the teething troubles of Britain’s notorious SA80 come to mind – focusing on reliability may have been a wise decision.


Israel builds its own high-tech military equipment, such as tanks, missiles and drones. Not bad for a nation of just 8.5 million people living in a state the size of New Jersey. The IWI Tavor was designed and produced by the IWI which stands for Israel Weapons Industry.

In its short history, Israel has also proven adept at designing rifles. Perhaps its most famous firearm is the legendary Uzi submachine gun, an almost iconic 1950s design made famous by the photo of a U.S. Secret Service agent waving an Uzi during the attempted 1981 assassination of President Ronald Reagan. Originally conceived as a cheap, simple weapon for Israeli troops, the Uzi was widely used by police and military forces around the world.

The Uzi is still around but showing its age, supplanted by more modern submachine guns like the FN P90. Now Israel’s modern firearm is the Tavor assault rifle, manufactured by Israel Weapon Industries, which is now making its latest Tavor 7 model available in the United States.

IWI Tavor to replace M4 Carbine

First introduced in 2001, the Tavor was selected by the Israel Defense Forces in 2009 to replace the American-made M16 and M4 as its first-line rifle. First thoughts by the end-users were highly positive. It is produced in two main variants: the TAR-21 and the CTAR-21.

The version selected by the Israel Defence Forces (IDF) was named as Tavor X95 (also known as the Micro Tavor or MTAR). The first X95 bullpup rifles were issued to infantry units in 2013.

Tavor guns are ideal for the various missions including missions that require long days in the wilderness, close-quarter combat, long-range firefights, and “shoo- shoo” (i.e. silent) operations. With an effective range of 550 meters, the Micro- Tavor is the most versatile weapon in the IDF.

In fact, that means the Tavor is designed as a CQB weapon, but with modifications, like a bipod and scope could be used to engage targets at longer distances, all versions commercially available are single pull weapons and are not automatic weapons.


If nothing else, the Tavor is distinctive by its bullpup configuration, in which the receiver and magazine are located behind the trigger, thus allowing a shorter weapon. Bullpup rifles have some reputation for being less accurate weapons than conventional long-barreled rifles, but the IDF wanted a weapon compact enough to be used by mechanized infantry crowded into their armored vehicles, as well as in close-range or urban combat.

The Tavor primarily fires NATO 5.56 x 45-millimeter rounds, though it can also shoot 9-millimeter ammunition. The weapon is just 25 to 28 inches long, and weighs 7 to 8 pounds, depending on the model. Though its shorter than the M-4, its barrel length is about the same, enabling it to fire high-velocity rounds. It uses a long-stroke piston system: though this is an old type of mechanism — it was used by the M-1 Garand and AK-47 rifles – it is also reliable. Given the problems experienced by some bullpup designs — the teething troubles of Britain’s notorious SA80 come to mind – focusing on reliability may have been a wise decision.

IWI Tavor Variants


The standard variant with a 457mm(18in) long barrel.


The GTAR-21 has a notched barrel, to accept an M203 40 mm under-barrel grenade launcher.


The CTAR-21 is a compact shorter 380mm(15in) barrel variant intended for commandos and special forces, but has become more favored than the standard TAR-21 throughout the IDF.


The STAR-21 is a designated marksman variant with folding under-barrel bipod and Trijicon ACOG 4× magnification sight.


The Tavor X95 (also referred to as the MTAR-21) is the variant of the Tavor that was selected as the future standard infantry weapon of the IDF in 2009.


The IWI Tavor 7 is the latest iteration of the Tavor. It is chambered in 7.62×51mm NATO. It is a fully ambidextrous rifle.


The semi-automatic Tavor Carbine (TC-21) was first made available for civilian customers to purchase in Canada from 2008.


The IWI Tavor is used by various units – especially special forces and police SWAT teams — in almost 30 nations. As is common with Israeli arms, these include several South American, Central American, African, and Asian nations, including Colombia, Mexico, Guatemala, Senegal, and Nepal. In addition, the nation of Georgia has replaced some of its Kalashnikovs with IWI Tavor. Vietnam and India also use them. As for the United States., a few states and local police departments have opted for the IWI Tavor.

  1. Besides being semi-auto only, what is the difference between the commercial models and what is actually issued to the Israeli Military ? Are the same specs for the Military used in the commercial models ? Same materials and QC ? What was done to the T7 (besides larger bolt and barrel) to be durable enough to handle the 7.62X51 ?
    Thank you.
