M320 Grenade Launcher Module (GLM) is a German made Grenade Launcher which is the US military's designation for a new single-shot 40mm grenade launcher system to replace the M203 in US army. M320 was designed in 2008 based on the AG36 key features and added with a foregrip and a detachable stock for using as a stane-alone launcher. The M320 entered production in late 2008 and offically fielded in mid 2009 by the 1st Brigade Combat Team, 82nd Airborne Division. A distinctive feature of the M320 is the detachable buttstock. As long as it has a buttstock it is an autonomous weapon. After detaching it, you can use the top mounting clamp to attach is to a Picatinny rail and hang it under the barrel of an assault rifle.
