High Quality Content by WIKIPEDIA articles! The MGL (Multiple Grenade Launcher) is a lightweight 40 mm semi-automatic, 6-shot grenade launcher developed and manufactured in South Africa by Milkor (Pty) Ltd. The MGL was demonstrated as a concept to the South African Defence Force (SADF) in 1981. The operating principle was immediately accepted and subjected to a stringent qualification program. The MGL was then officially accepted into service with the SADF as the Y2. After its introduction in 1983, the MGL was gradually adopted by the armed forces and law enforcement organizations of over 30 countries; it has since been used in harsh environments ranging from rain forests to deserts. Total production since 1983 has been more than 50,000 units.
