M203
The iconic US under-barrel 40mm grenade launcher — a single-shot, slide-forward break-action launcher that equips M16 and M4 rifles with high-explosive, HEDP and specialty rounds, the standard squad-level grenade system for 30+ years.
The M320 is a single-shot 40×46mm low-velocity grenade launcher that mounts under a service rifle or operates as a standalone weapon with a collapsible stock, adopted by the U.S. Army in 2009 to replace the M203.
