M32 MGL
The M32 MGL is a six-shot revolver grenade launcher in 40×46 mm, fielded by the US Marine Corps and SOCOM, offering rapid semi-automatic fire of up to six rounds in under three seconds.
A U.S.-adopted, South African-designed six-shot revolver-style 40 mm grenade launcher that delivers rapid suppressive or point target fire for the infantry squad.
Overview
The M32 Multiple Grenade Launcher (MGL) is a shoulder-fired, semi-automatic revolving-cylinder grenade launcher chambered for the NATO 40×46 mm low-velocity grenade. The US Marine Corps adopted the weapon in 2005 as the M32, and the strengthened M32A1, also known as the Mk 14 Mod 0 in SOCOM parlance, later added the ability to fire 40×51 mm medium-velocity grenades. The launcher’s six-round cylinder allows an operator to put a full payload downrange in under three seconds, making it a high-volume suppressive tool for the infantry squad.
Development
The M32 descends from the Milkor MGL-140, a six-shot revolver launcher designed by Andries Piek in South Africa and first fielded in the 1980s. U.S. interest emerged in the 1990s, and after testing, USSOCOM adopted the weapon, followed by the Marine Corps in 2005 under the M32 designation, as detailed by Forgotten Weapons. The M32A1, also called the MSGL (Multi-Shot Grenade Launcher), was re-engineered with a steel frame to withstand higher-pressure 40×51 mm medium-velocity rounds, and became the weapon of record for the USMC, with procurement managed through Milkor USA.
