M320 Grenade Launcher Module (GLM) is the U.S. military's designation for a new single-shot 40 mm grenade launcher system to replace the M203 for the U.S. Army, while other services initially kept using the older M203. The M320 uses the same High-Low Propulsion System as the M203. The M320 can be mounted on the M16 series of rifles, while the M320A1 can be mounted on the M4 series of carbines.
