IWI Tavor

The IWI Tavor TAR-21 is an Israeli bullpup assault rifle chambered in 5.56×45mm NATO caliber with a selective fire system, selecting between semi-automatic mode and full automatic fire mode.
The Tavor is designed and produced by Israel Weapon Industries (IWI). It is produced in two main variants: the TAR-21 and the CTAR-21.
Built around a long-stroke piston system (as found in the M1 Garand and AK-47), the Tavor is designed to maximize reliability, durability, simplicity of design, and ease of maintenance, particularly under adverse or battlefield conditions.
In 2009, the Tavor X95 (also known as the Micro Tavor or MTAR) was selected by the IDF to gradually replace the M16 assault rifle and M4 carbine variants as the standard-issued weapon of the Israeli infantry by the end of 2018. The first X95 bullpup rifles were issued to infantry units in 2013. Both the TAR-21 and X95 are part of the Tavor family of rifles, along with the Tavor 7.
History and objectives.
Israel Military Industries (the small arms branch of IMI was privatized into Israel Weapon Industries) initiated the Tavor development team in 1995, under the direction of gun designer Zalmen Shebs.
The objective of the project was to create an assault rifle that was more reliable, durable, and easier to maintain than the M4A1 Carbine, while also being better suited to close-quarters combat and mechanized infantry roles. As a result, they hoped that the weapon would be officially adopted by the Israel Defense Forces.
Due to the military's close-quarters and mechanized infantry requirements, the project team selected a bullpup design that would allow the weapon to be compact while keeping a long barrel able to achieve ballistically favorable high muzzle velocities. A long-stroke piston system, similar to that found in the AK-47 and M1 Garand, was selected to ensure the weapon's reliability under adverse conditions.
Trials in Israel.
The Tavor prevailed over the M4A1 Carbine in a series of trials conducted during 2001 and 2002. Qualities tested included Mean Rounds Between Failures (MRBF), reliability, ergonomics during long marches, and ease-of-maintenance.
In 2009, the IDF selected the Tavor X95 as its future standard issue rifle for all branches of the infantry, with a gradual changeover beginning in 2006 and expected completion among front line troops by end of year 2018.
Design details and engineering.
Bullpup configuration.
The Tavor uses a bullpup configuration, in which the receiver, bolt carrier group and magazine are placed behind the pistol grip. This shortens the firearm's overall length without sacrificing barrel length. As a result, the Tavor provides carbine overall length, yet can achieve rifle muzzle velocities if equipped with a rifle-length barrel.
Long-stroke piston system.
The Tavor uses a non-lubricated long-stroke piston system, as found in the M1 Garand, IMI Galil, and the AK 47. Like in the AK-47, the long-stroke piston mechanism contributes to the extreme forcefulness of the TAR-21's extraction and chambering.
The Tavor attachment of the piston to a heavy bolt carrier, and the extension of the mainspring into the hollow stem of the bolt carrier, bears a family resemblance to the internal mechanism of the AK-47.
Ambidexterity and modularity.
The Tavor has ejection ports on both sides of the rifle so it can easily be reconfigured for right or left-handed shooters. However, this process requires partial disassembly, so it cannot be quickly reconfigured while the rifle is in use. An issue related to this is the original plastic cover on the unused ejection can allow gas to escape during the course of fire. Due to the bullpup design this vents right under the shooters face causing issues, such as inhaling ejection gases and the fouling of glasses and face with ejection debris. The issue is exacerbated when the weapon is suppressed. The characteristic black smudge from this has been nicknamed "Tavor face" by some shooters. This has been addressed by various non-factory solutions which increase sealing of the unused port.
Its ambidextrous fire mode selector above the pistol grip has a semi-automatic mode and a fully automatic mode.
The Tavor features a self-contained, drop-in trigger group so that the trigger group can be changed or replaced without the use of additional tools.
The Tavor can also be mounted with the M203 grenade launcher (GTAR-21).
Chambering, cartridges and ammunition feeding.
The Tavor is primarily chambered in 5.56×45mm NATO, although 9×19mm Parabellum and 5.45×39mm Russian models are also available.
The IDF uses both M193 and M855 5.56×45mm rounds. M193 rounds are used by regular infantrymen for better terminal effects at shorter distances, while the heavier M855 is used by sharpshooters.
The Tavor accepts standard STANAG magazines.
Last round bolt-open catch.
The Tavor features a last round bolt catch, whereby the bolt holds open after the last round discharges. This is a request of modern armies, as it helps to allow soldiers to know when their magazine empties and to reduce reloading times during combat while also not requiring manual action cycling after.
Barrel.
Tavor barrels are made from CrMoV steel and cold-hammer-forged (CHF) on the premises of the IWI factory in Ramat HaSharon. The TAR-21 barrel is 457mm in length and is chrome-lined for durability and corrosion resistance. The barrel features 6 grooves in a 178 mm (1 in 7 inch) twist, or 32 calibers right hand twist rate.
The barrel is fitted with a 'birdcage' style flash suppressor, which can be fully disassembled without the need for additional tools.
Reliability, ease-of-maintenance and waterproofing.
The design objectives of the Tavor aimed for reliability and ease-of-maintenance, particularly under adverse or battlefield conditions. According to Russell C. Tilstra, the Tavor is "easily considered more reliable" than the M16 and M4 series rifles.
The Tavor is designed to be easily field-stripped, without the need for any additional tools.
It is waterproofed and its internal mechanism is sealed from outside elements, so that it can pass over-the-beach requirements.
Variants.
TAR-21.
The Tavor TAR-21 is the standard variant with a 457 mm (18 in) long barrel.
The Israeli firearm manufacturer, Israel Weapon Industries produces the Tavor TAR-21 in different variations:
GTAR-21.
The GTAR-21 has a notched barrel, to accept an M203 40 mm under-barrel grenade launcher.
CTAR-21.
The CTAR-21 is a compact shorter 380 mm (15 in) barrel variant intended for commandos and special forces, but has become more favored than the standard TAR-21 throughout the IDF.
STAR-21.
The STAR-21 is a designated marksman variant with folding under-barrel bipod and Trijicon ACOG 4× magnification sight
Tavor X95 (MTAR-21).
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. In 2013, the X95 was issued for the first time as the standard infantry weapon to recruits of the Givati Brigade.
With the use of a relatively simple conversion kit, the X95 can be converted from a 5.56 mm assault rifle to a 9 mm submachine gun. A suppressor can also be added to the weapon, as part of the 9 mm conversion kit. A grenade launcher can also be attached to the X95.
Tavor 7.
The IWI Tavor 7 is the latest iteration of the Tavor. It is chambered in 7.62×51 mm NATO. It is a fully ambidextrous rifle.
Ukrainian licensed Tavors.
Ukraine purchased a license for Tavors to be manufactured by Ukrainian firearm manufacturer, RPC Fort.
TC-21.
The semi-automatic Tavor Carbine (TC-21) was first made available for civilian customers to purchase in from 2008. The Canadian civilian version initially shipped with the Mepro reflex sight and a slightly longer barrel to meet the Canadian requirement for non-restricted semi-automatic centerfire rifles to have a barrel length of at least 470 mm. Current versions are shipped with a full-length Picatinny rail, without optics. In Europe, the Czech company Zeleny Sport recently (December 2015) imported Israeli-made TC-21s, equipped with Mepro M5 or M21 reflex sight, which are now available for both civilian and law enforcement customers.
In 2013, IWI started a US subsidiary, IWI US, which is manufacturing the semi-automatic TC-21 as the Tavor SAR for U.S. sales. The weapon is manufactured with a combination of Israeli and US parts. IWI US had shipped 50,000 Tavor SARs to US civilian customers by early 2016.
IWI US sells the Tavor SAR in variety of variants; they include:
Note: IWI US sells their Tavor SARs in a variety of colors, including Black (B), Flat Dark Earth (FD), and OD Green (G); the letter "B" subsequent to "TS" in the rifles' designations can be switched with any of the colors' respective letters.
Aftermarket parts.
A significant aftermarket of spare and replacement parts has developed around the Tavor, including the development of match grade accurizing triggers for the bullpup rifle that are produced by manufacturers such as Geissele Automatics and double stage trigger pack TAV-D from Shooting Sight.
Shlomi Sabag, Deputy CEO of IWI, says that one of the indicators of the success of the rifle in the shooting sports or civilian market is the fact that "an aftermarket of products associated with the Tavor bullpup rifle, like triggers, has evolved very quickly".
Awards.
The Truth About Guns website awarded the Tavor with TTAG Reader's Choice Award for Best Rifle of 2013.
The National Rifle Association's "American Rifleman" awarded the Tavor the 2014 Golden Bullseye Award as its rifle of the year. The NRA's prestigious award, now in its twelfth year, aims to award the best products available to civilian shooters.
The Tavor X95 was awarded the NRA's rifle of the year award for 2017.
