Original U.S. M72A2 - M190 LAW Light Anti-Tank Weapon Launcher with 35mm Training Insert - Deactivated
Original Item: Only one available. This is an inert non-firing BATF compliant M72A2 converted to M190 Practice LAW Light Anti-Tank Weapon offered in very good condition. It also includes the 35mm training round insert. These are a timeless design, which the U.S. Military has tried to replace in the past, but was unable to find anything better than these disposable launchers. We were watching the trailers for the Terminator: Dark Fate movie, and noticed that Sarah Connor, played by Linda Hamilton, clearly uses an M72 LAW launcher, which is also seen in promotional pictures. It is a more modern version, but functionally identical, and the look is the same! They even still use the SAME instruction label! These make very impressive wall hangers, and now you can say, "Just like the one in the latest TERMINATOR film!"
This very nice example has both front and rear sights intact, though it does not have the rear cover, so the strap/cover cannot be attached. This example was converted to an M190 Subcaliber LAW trainer
This example still has part the original paint stamping:
ROCKET HE 66 MM ANTITANK M72 A2
Under this is another applied label, which reads:
LAUNCHER, ROCKET M190
The rest of the label has scratches so cannot be easily read.
The M72 LAW (Light Anti-Tank Weapon, also referred to as the Light Anti-Armor Weapon or LAW as well as LAWS Light Anti-Armor Weapons System) is a portable one-shot 66-mm unguided anti-tank weapon. It has been in use continuously in various versions since the 1960's. This example most likely dates from the 1970s, and was then converted to an M190 35mm Trainer. The subcaliber insert can be removed, and is still in great shape.
The launcher itself can still extend and both sights flip up, however the trigger mechanism has been deactivated, so it no longer cocks and dry fires. Paint is still great, and the instruction label is partly intact as well. Safety handle/cocking lever missing, as it would not be needed in this configuration.
This is definitely one of the more interesting LAW launchers we have had. Ready to display!
The solid rocket propulsion unit was developed in the newly formed Rohm and Haas research laboratory at Redstone Arsenal in 1959, then the full system was designed by Paul V. Choate, Charles B. Weeks, Frank A. Spinale, et al. at the Hesse-Eastern Division of Norris Thermadore. American production of the weapon began by Hesse-Eastern in 1963, and was terminated by 1983; currently it is produced by Nammo Raufoss AS in Norway and their subsidiary Nammo Talley, Inc. in Arizona.
In early 1963, the M72 LAW was adopted by the U.S. Army and U.S. Marine Corps as their primary individual infantry anti-tank weapon, replacing the M31 HEAT rifle grenade and the M20A1 "Super Bazooka" in the U.S. Army. It was subsequently adopted by the U.S. Air Force to serve in an anti-emplacement/anti-armor role in Air Base Defense duties.
In the early 1980s, the M72 was slated to be replaced by the FGR-17 Viper. However, this program was canceled by Congress and the M136 AT4 was adopted instead. At that time, its nearest equivalents were the Swedish Pskott m/68 (Miniman) and the French SARPAC.

The increased importance of tanks and other armored vehicles in World War II caused a need for portable infantry weapons to deal with them. The first to be used (with limited success) were Molotov cocktails, flamethrowers, satchel charges, jury-rigged landmines, and specially designed magnetic hollow charges. All of these had to be used within a few meters of the target, which was difficult and dangerous.
The U.S. Army introduced the bazooka, the first rocket-propelled grenade launcher. Despite early problems, it was a success and was copied by other countries.
However, the bazooka had its drawbacks. Large and easily damaged, it required a well-trained two-man crew. Germany developed a one-man alternative, the Panzerfaust, having single-shot launchers that were cheap and requiring no special training. As a result, they were regularly issued to Volkssturm home guard regiments. They were very efficient against tanks during the last days of World War II. However, the Panzerfaust was not a rocket launcher but instead a recoilless rifle.
The M72 LAW is a combination of the two World War II weapons. The basic principle is a miniaturized bazooka, while its light weight and cheapness rival the Panzerfaust.
The weapon consists of a rocket within a launcher consisting of two tubes, one inside the other. While closed, the outer assembly serves as a watertight container for the rocket and the percussion-cap firing mechanism that activates the rocket. The outer tube contains the trigger, the arming handle, front and rear sights, and the rear cover. The inner tube contains the channel assembly, which houses the firing pin assembly, including the detent lever. When extended, the inner tube telescopes outward toward the rear, guided by the channel assembly, which rides in an alignment slot in the outer tube's trigger housing assembly. This causes the detent lever to move under the trigger assembly in the outer tube, both locking the inner tube in the extended position and cocking the weapon. Once armed, the weapon is no longer watertight, even if the launcher is collapsed into its original configuration.
When fired, the striker in the rear tube impacts a primer, which ignites a small amount of powder that "flashes" down a tube to the rear of the rocket and ignites the propellant in the rocket motor. The rocket motor burns completely before leaving the mouth of the launcher, producing gases around 1,400 °F (760 °C). The rocket propels the 66-mm warhead forward without significant recoil. As the warhead emerges from the launcher, six fins spring out from the base of the rocket tube, stabilizing the warhead's flight. The early LAW warhead, developed from the M31 HEAT rifle grenade warhead, uses a simple, but extremely safe and reliable, piezoelectric fuze system. On impact with the target, the front of the nose section is crushed causing a microsecond electric current to be generated, which detonates a booster charge located in the base of the warhead, which sets off the main warhead charge. The force of the main charge forces the copper liner into a directional particle jet that, in relation to the size of the warhead, is capable of a massive amount of penetration.
A unique mechanical set-back safety on the base of the detonator grounds the circuit until the missile has accelerated out of the tube. The acceleration causes the three disks in the safety mechanism to rotate 90° in succession, ungrounding the circuit; the circuit from the nose to the base of the detonator is then completed when the piezoelectric crystal is crushed on impact.
The M72 LAW was issued as a prepackaged round of ammunition. Improvements to the launcher and differences in the ammunition were differentiated by a single designation. The original M72 warhead penetrated 200mm/8 inches of armor, while the improved M72A2 model boosts this to 300mm/12 inches.
A training variant of the M72 LAW, designated the M190, also exists. This weapon is reloadable and uses the 35-mm M73 training rocket. A subcaliber training device that uses a special tracer cartridge also exists for the M72. A training variant used by the Finnish armed forces fires 7.62-mm tracer rounds.
The US Army tested other 66-mm rockets based on the M54 rocket motor used for the M72. The M74 TPA (Thickened Pyrophoric Agent) had an incendiary warhead filled with TEA (triethylaluminium); this was used in the M202A1 FLASH (FLame Assault SHoulder weapon) 4-tube launcher. The XM96 RCR (Riot Control Rocket) had a CS gas-filled warhead for crowd control and was used with the XM191 quadruple-tube launcher.
Once fired in combat, the launcher is required to be destroyed to prevent its use by the enemy as a booby-trap; the enemy could collapse the launcher to its original configuration, fill it with explosives, and rig it to explode if moved by a soldier believing it to be unused. Due to the single-use nature of the weapon, it was issued as what is called a "wooden round" of ammunition by the Canadian Army and the United States Army, requiring no checks or maintenance, just as small-arms ammunition can be stored in the same manner for years without any problems.
