Decidedly Different: The IWI Tavor

Israel Weapon Industries has established a U.S. operation to bring the Tavor SAR, a semi-automatic-only version, to Americans.

When it comes to protecting its people, no nation is more resolute than Israel. With a land area about the size of New Jersey, and fewer than 8 million citizens, the country is relatively small and geographically vulnerable to the hostile adversaries that surround it. As evidence of its resolve, Israel is said to spend a greater percentage of its gross domestic product on national defense than any other nation.

With respect to small arms, that commitment has evidenced itself in a raft of designs adopted from other nations—the Glock 17 and Browning Hi-Power in handguns, the M14 and AK-47 in rifles and the M1919 and M2 Brownings in machine guns to name but a few—and in several domestically produced arms that have become world standards because of their reputation for reliability. Those include the Uzi submachine gun, the Galil rifle, the Negev machine gun and the Tavor, an advanced 5.56x45 mm NATO bullpup rifle platform that has been in service with Israeli Defense Forces (IDF) troops for nearly a decade. Having already spun off a range of specialized variants, including some in other chamberings, the Tavor represents the most advanced solution to date employed by Israeli forces fighting a seemingly endless series of urban conflicts.

Conceived Out Of Conviction
Officially designated TAR-21, for “Tavor Assault Rifle, 21st century,” the select-fire rifle was named after Israel’s Mount Tabor, which rises, sentinel-like, above the Via Maris roadway in Israel’s lower Galilee region—a route that has held strategic importance since Biblical times.

The rifle’s development began two decades ago when the Israelis—at the time relying primarily on the Galil and its variants alongside the M16 rifle and M4 carbine for infantry use—found themselves facing increasingly dynamic and demanding urban combat situations. Dismounting from vehicles and shooting on the move in and around buildings proved a need for a more agile, adaptable platform. In addition, better accuracy and easier transitioning from daytime to nighttime shooting were identified as areas that should be improved.

The IDF began a collaboration with Israel Weapon Industries (IWI), the privatized entity that was previously the state-owned Israel Military Industries, on the research and development phase of the project in March 1995. It continued ergonomic tests and development on the gun for two years, and by 2000, the Tavor began to see broad testing with IDF infantry companies. The following year, field tests were conducted pitting the Tavor against the M4 at Camp Mitkan Adam, an IDF training base and home to its counter-terrorism warfare center and sniper school.

According to Amihai Dekel, a project manager with IWI in Israel and a reserve officer in the Israeli Special Forces, whose career has included troop commands at the platoon and company levels, the Tavor underwent a series of rigorous tests between November 2001 and March 2002 with two IDF brigades that evaluated it throughout different scenarios, theatres and configurations. Numerous aspects of the new platform were considered, including: Mean Rounds Between Failures (MRBF); accuracy and retention of zero using various sights; human ergonomics during extended periods of use, including marches as long as 37 miles; speed and accuracy of sighting in daytime and nighttime with iron sights, magnified and night vision optics, and lasers; use with the M203 grenade launcher; and maintenance-relevant issues.

Dekel said that, in the end, the Tavor prevailed over the M4, although he declined to share specifics about how the guns scored. “The results are clear, the Tavor is the [gun] of choice for the IDF and for Israeli special and elite forces.” The IDF officially adopted the Tavor in 2003 and within three years it was in the hands of infantry brigades and special forces throughout Israel.

Formed For Function
At first glance the Tavor is likely to evoke the usual criticisms typically leveled at the bullpup concept by its detractors—chief of which is that they are “awkward.” But that is often more a reaction to appearance rather than a thoughtful consideration of functionality. In the Tavor’s case, shouldering it goes a long way toward dispelling that notion.

By way of definition, a bullpup’s chamber, magazine well and fire-control components lie behind its pistol grip and trigger. That means no space is wasted on a buttstock that, typically, serves only to position a rifle against the shooter’s shoulder. Therein lies the bullpup’s chief advantage: short overall length with a standard-length barrel. For example, an M4 carbine with its stock fully collapsed measures 29¾ inches with a 14½-inch barrel. The Tavor measures 261⁄8 inches with a 16½-inch barrel. Also, compared to rifles with folding or collapsing stocks, Tavor and other bullpups need not be “deployed” before being employed.

According to Dekel, “The Tavor has exceptional situational ergonomics … I hold it naturally and can operate it efficiently even when I’m under physical pressure and fatigue, and the ultra-compact form factor allows for easy transitions in close-quarter situations and in different vehicles. The full-length barrel also means no loss of downrange ballistic efficiency.”

Despite the fact that it has a one-piece, injection-molded polymer stock, which gives the rifle its basic shape, the Tavor has a robust feel in the hand. Nothing about its parts or controls appears flimsy or underengineered. In the magazine well area, for example, the stock’s wall thickness averages ¼ inch. The trigger, fire-control components, flip-up sights, ejection port cover, magazine catch and push-button sling swivels are made of steel.

Engineered To Excel
Fieldstripping the semi-automatic-only Tavor SAR as sold by IWI U.S. and described hereafter, involves simply pushing out a captive cross pin located in the stock just forward of the buttplate’s top, allowing the buttplate to hinge downward and the gas piston/bolt carrier group to be withdrawn out the rear.

The black anodized aluminum top cover forms a full-length Picatinny rail and houses the front and rear sights—the former being adjustable for windage and elevation with an AR-type post. It is held at its front by a steel block and at two points midway back by two Allen-head machine screws. They engage two blocks clamped to the gas cylinder assembly, which is held to the barrel by two cross pins. The design essentially mates the mechanical and optical sights to the barrel, ensuring they retain zero.

Once the top cover, front swivel and foregrip assemblies, and the flash hider and its jam nut, are removed, the cocking assembly can be pulled forward off the gun. The barrel assembly is then removed with the aid of a specially shaped wrench by turning a socket on the gun’s right side 180 degrees while simultaneously pressing a safety catch on the opposite side. That rotates a pin out of engagement from a semi-circular groove in the barrel extension, which is machined with the chamber and locking lug recesses. The extension is pinned and threaded to the barrel proper, which measures 0.640 inches in diameter immediately ahead of it and 0.585 inches behind the muzzle. It is chambered in 5.56x45 mm NATO and rifled with a 1:7-inch twist.

The 7075-E6 hard-anodized machined aluminum receiver is a U-shaped chassis measuring 111⁄8x11⁄8x2 inches that is Teflon-coated. A 1.023-inch diameter hole at its front accepts the barrel extension. Rails machined into the receiver engage grooves in the side of the 7/8 x 3¼ x 21⁄8-inch bolt carrier. Mounted to the carrier is a 4340 steel piston crosspinned to a recoil-spring-guide tube along with the recoil spring and guide rod, a bolt-rotation-control bar and, at the rear, a polymer buffer. The 3-inch-long, one-piece right-hand bolt features a recessed face with radial locking lugs at 11 o’clock, 3 o’clock and 6 o’clock. The latter takes the form of two smaller lugs that coincide with M4-type feed ramps in the barrel extension. A 0.233-inch-wide extractor lies at 10 o’clock next to the uppermost lug, and a plunger-style ejector lies at 3 o’clock on the bolt’s face. The bolt is cammed into and out of battery, rotating only 36 degrees, by a 0.273-inch pin transversely mounted through its channel in the carrier.

There is a very simple adjustment to the trigger pack that will bring the trigger pull to below 6. Just search for it.

11 and a half lbs trigger pull? That's the same as the constantly-derided NYC Glock trigger.

It caused me to smile, the two magazine capacity's. Thirty and 42, copied from the AUG, what most people do not know, the 42 capacity model, started out as a 40 round capacity one. But when came the time to test the completed magazines? The loaded capacity was 42! So the easy fix, weld up the mold, and cut the number 42 in to it! I found this out in a visit to the factory, in the town of Steyr, in Austria.

Gotta start saving for one of these.
