Historical Significance
The M120 120mm Mortar represents the culmination of decades of mortar development and remains one of the most powerful and effective crew-served indirect fire weapons ever 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" heavy mortar platforms while providing significantly enhanced range, firepower, and battlefield effectiveness.
The M120 became a cornerstone of modern infantry and mechanized fire support doctrine, serving with U.S. Army and Marine Corps units around the world. Capable of delivering devastating high-explosive, smoke, illumination, and training ammunition, the M120 has seen extensive service from the Cold War through modern combat operations in Iraq, Afghanistan, and other theaters.
Known for its accuracy, reliability, and destructive capability, the M120 remains one of the most respected heavy mortar systems in military service today.

Important Notice
This mortar is being sold in kit form, which means it is not being sold as a registered destructive device. This is a stepped transaction, which means you pay for the entire kit upfront and we can ship everything to you but the cup (receiver) and the tube (barrel). The cup, which is the firearm receiver, must be shipped to an FFL licensee within your state. This will transfer as a standard Title 1 firearm receiver, no different than a standard rifle, shotgun, or handgun. You will go to your dealer and fill out the standard 4473 over-the-counter firearms transaction record. Once the receiver is in your possession, you will need to fill out and submit a Form 1 (application to make and register an NFA firearm) to the BATFE, requesting permission to make a destructive device. Once you have received the approved Form 1 back from the ATF, you will provide us a copy of the Form 1 for our records, and then the tube/barrel will be shipped directly to you. Engraving services are available if you would like us to engrave your maker information on the cup after your Form 1 has been approved. All NFA rules apply.
The cup screws onto the base of the tube, and you now have a complete, legally registered, destructive device.
