Lightweight Medium Machine Gun (LWMMG)

Unmatched Accuracy and Extended Range

The next generation Lightweight Medium Machine Gun (LWMMG) gives warfighters a distinct advantage in both extended and close-in fighting. Eliminating the gap between 7.62mm and .50 caliber weapons, the LWMMG utilizes the highly efficient .338 Norma Magnum cartridge to offer unmatched accuracy and lethality while extending the battlespace out to an impressive 1,700 meters.

At 1,000 meters, the LWMMG is capable of defeating Level III body armor and incapacitating soft skinned vehicles by delivering over 1,900 foot pounds of energy to the target – more than four times the terminal effect of the 7.62mm NATO cartridge. Weighing less than 24 pounds and featuring a fully collapsible stock, the LWMMG offers superior mobility and portability in both mounted and dismounted operations.

Features a revolutionary recoil mitigation system that offers a recoil profile similar to a 7.62mm NATO machine gun, but utilizing the much more powerful .338NM cartridge.
