The FN® MK 13 EGLM (Enhanced Grenade Launcher Module) accepts all NATO-standard 40mm low-velocity grenades. Future enhancements to the MK 13 will permit the use of enhanced medium-velocity grenades now in development, offering greater range and larger payloads. The MK 13 may be quickly mounted underneath either the FN® MK 16 or FN® MK 17, or it may be configured as a stand-alone launcher with a telescoping buttstock. The MK 13 EGLM is tested, operational, and currently deployed in harm’s way with elite units of the U.S. Armed Forces.

The MK 13 EGLM is now serving with America’s warfighters in hostile environments around the globe, providing them with the ability to operationally employ the full range of lethal, non-lethal, and special purpose 40mm ammunition.
