11 October 2018

General Dynamics Ordnance and Tactical Systems’ (OTS’s) Lightweight Medium Machine Gun (LWMMG) has undergone a substantial number of modifications to its internal and external components. The weapon is intended to fill the capability gap between the 7.62×51 chambered light and .50-calibre heavy machine guns in US Marine Corps (USMC) and Special Operations Command (SOCOM) service.

Jane’s has learned the LWMMG has fired at least 25,000 rounds without a single part failure and is to be evaluated by the SOCOM and USMC in the next year.

The latest iteration of the LWMMG, which has still not been unveiled to the public, features a redesigned handguard and a new pistol grip and trigger guard assembly.
