The Lightweight Medium Machine Gun officially displayed by General Dynamics at AUSA 2014.

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, thanks to a muzzle velocity of 2,650 feets per second. Weighing less than 24 pounds and featuring a fully collapsible stock, the LWMMG offers superior mobility and portability in both mounted and dismounted operations. The LWMMG offers a heavy rate of fire of 500 rounds/min.

General Dynamics Ordnance and Tactical Systems’ LWMMG is a simple, well-designed machine gun ideally suited to provide long range lethality and standoff to U.S. forces. The LWMMG’s portability and integration of standard optics combined with the superior ballistic coefficient of the .338 NM cartridge provide overmatch capability compared to all known portable machine guns in the world.

The LWMMG features a quick change barrel with fixed headspace and timing as well as integrated MIL-STD-1913 rails, allowing the use of a variety of optics, lasers and accessories.

The weapon’s simple assembly quickly breaks down into six functional groups, and all field maintenance is performed without the need for special tools. The LWMMG adapts to currently fielded tripods and standard vehicle mounts. The patented technology of the Short Recoil Impulse Averaging substantially reduces recoil and improves target retention during automatic fire. The light weight and low recoil of the weapon affords operators of all sizes the ability to carry and deliver lethal effects.

The Lightweight Medium Machine Gun is a weapon system that greatly expands the operational capabilities of the warfighter. The weapon is ideally suited for both mounted and dismounted operations: the increase in effective range and lethality in a lightweight form is substantial for dismounted operations. The mounted configuration provides long range, accurate fires currently associated with the M2 Browning, but without the burden of a heavier weight. M192 tripod, or various vehicle mounts and low recoil of the weapon affords operators the ability to carry and deliver lethal effects in many operational situations.
