Historical Significance
The M120 120mm Mortar represents the result of decades of mortar development. It remains one of the most powerful and effective crew-served indirect-fire weapons adopted by the U.S. military.
Derived from the Israeli Soltam K6 mortar system and adopted by the United States during the 1980s, the M120 was designed to replace aging 4.2-inch heavy mortar systems while providing greater range, firepower, and battlefield effectiveness.
The M120 became an important part of modern infantry and mechanized fire-support doctrine. Capable of firing high-explosive, smoke, illumination, and training ammunition, the M120 has served from the closing years of the Cold War through modern combat operations in Iraq, Afghanistan, and other theaters.
Known for its accuracy, reliability, and powerful capabilities, the M120 remains one of the most respected heavy mortar systems in military service.

Important Notice
This mortar is sold in kit form and is not sold as a registered destructive device. This is a stepped transaction. The buyer pays for the complete kit upfront, and we can ship all components except the receiver (cup) and barrel (tube).
The receiver must be shipped to an FFL licensee in the buyer’s state. It transfers as a standard Title 1 firearm receiver. The buyer must complete the required ATF Form 4473 through the receiving dealer.
After taking possession of the receiver, the buyer must submit ATF Form 1, Application to Make and Register a Firearm, requesting approval to make a destructive device.
Once the approved Form 1 is received, the buyer must provide us with a copy for our records. We can then ship the barrel directly to the buyer.
Engraving services are available if you would like us to engrave your required maker information on the receiver after your Form 1 has been approved.
All NFA rules apply.
The receiver screws onto the base of the barrel to create the complete, legally registered destructive device.
