The M32 MGL (Multiple Grenade Launcher) is a semi-automatic, 40mm rotary-action grenade launcher. Think of it as a giant, beefed-up revolver designed for serious firepower rather than precision sniping. Originally developed in South Africa by Milkor as the Y2, it was adopted and modified by the U.S. Marine Corps (USMC) in the mid-2000s to bridge the gap between single-shot launchers (like the M203) and heavy belt-fed systems (like the Mk 19).
