– were the experiences obtained by the South African Defence Force, during the South African border war, – and in the Angolan civil war – that gave rise to the development of the MGL MK-1,at Milkor in South Africa.
Milkor (Pty) Ltd. responded to the ultimate requirements with a novelty type weapon, not only for its design, but also for the effectiveness demonstrated in the battlefield. Ultimately the new weapon used the concept of the drum or barrel of a revolver charger, generating a combination of speed and firepower simultaneously, qualities to which were added to the very low weight in relation to that provided by the fire power.
Thus, then presented in 1981 with the introduction of the Y2, officially initiating its service in 1983 after an extensive qualification program, and tested widely in operations, both in Angola and Namibia, progressively extending its promotion to 30 countries, in accordance with the manufacturing programs. Since the 1996, it was designated as MGL MK-1 (Multiple Grenade Launcher) the MGL is robust, reliable, and semiautomatic, has the ability to use most of the ammunition type 40X46 mm NATO, and also has a safety mechanism, above the handle, that prevents accidental firing of the weapon.
Its magazine houses six grenades, that is loaded manually and may be fired in three seconds, the weapon has progressive rotation grooves for arming grenades, and the sighting system is red dot (Red Dot), which provides its user precision calculations, of up-to 375 meters accuracy. The MGL has evolved today with a steel frame that replaced the original one and is fitted with four Picatinny type Rails for additional mounting accessories, presently there are two models of MGL; MK-1S differentiated by the length of the cylinders, allowing the first one to accommodate a variety of ammunition – HE, HE-FRAG, HEDP, AP-TP-, among which include “non-lethal” because this weapon is also being used by police forces.
These are presently being manufactured in South Africa, under License in Columbia by Indumil (MGL MK/1) and produced in Croatia is a very similar weapon/copy by RH Alan (RGB-6). In Columbia it is widely used by the Army and Marine Corps Infantry, in particular its counterinsurgency units employing one to four of these weapons, according to the unit and the mission intended for, Indumil, IM also manufactures the grenade IM 40 mm HE-AP.
