Colombian Army tests Milkor SuperSix 40mm grenade launcher as an alternative to US systems.

As reported by InfoDefensa on March 11, 2025, the South African company Milkor, represented in Colombia by Kriegsgott Group SAS, showcased the capabilities of its SuperSix MRGL 40mm multiple grenade launcher at the Tolemaida Military Base. On March 12, officers, non-commissioned officers, and special units of the Colombian Army conducted live-fire tests with the latest variant of Milkor's 40mm multiple grenade launcher series. Additionally, the SuperSix's firing capacity, effective range, and reloading mechanism could enhance the Colombian infantry firepower compared to the US grenade launchers currently used by the Colombian Army.

The SuperSix MRGL is a semi-automatic grenade launcher with a modular and ergonomic design, capable of firing six consecutive rounds in less than three seconds, depending on the operator. It can use both low-velocity ammunition (with an effective range of up to 400 meters) and medium-velocity ammunition (with an effective range of up to 800 meters), providing operational flexibility in both conventional and asymmetric combat scenarios. In addition to lethal projectiles, the weapon can fire low-lethality ammunition, including high-explosive, smoke, and blunt impact grenades. It meets MIL-STD-810G standards and NATO certification and is equipped with STANAG 4694 Picatinny rails and a standard MTG6 sight.

The SuperSix MRGL features a 40mm caliber and the ability to fire both standard and medium-velocity rounds. Its reloading system is based on a rotating six-shot cylinder with a double-action firing mechanism, allowing a firing rate of six rounds in three seconds. The barrel has a progressive rifling twist of one turn per 1,200 mm. Depending on the configuration, its total length varies between 746 mm and 859 mm, with an empty weight of approximately 5.96 kg. Its design allows for the integration of various sighting options based on user requirements.

Milkor introduced the SuperSix MRGL as the latest evolution in its 40mm multiple grenade launcher lineup, succeeding earlier models like the MGL-140. The launcher accommodates cylinder lengths of 105mm, 120mm, 140mm, and 160mm, allowing flexibility in munitions use. It enables a standard six-shot area coverage of at least 20 meters by 60 meters, with a robust construction designed to endure harsh battlefield conditions.

The SuperSix continues the evolution of grenade launchers developed by Milkor since the introduction of the MGL in 1981. This model has been widely adopted by armed forces and security agencies in over 60 countries. In Colombia, both the Army and the Marine Infantry have used the MGL MK-1L/S, the first Milkor model introduced in the country. Its rugged design and ability to operate in severe combat conditions have positioned it as an effective option in various operational theaters.

Milkor has significantly expanded its market presence, with reported orders surpassing 4,000 SuperSix MRGL units across Africa, Asia, the Middle East and North Africa (MENA), Europe, and South America between 2023 and 2024. Beyond grenade launchers, the company has broadened its manufacturing capabilities, delivering military vehicles such as the Milkor 4×4, an armored personnel carrier optimized for high-ground clearance and off-road operations. Additionally, Milkor has entered the unmanned aerial systems sector with the Milkor 380 UAV, a platform with an 18.6-meter wingspan, 35-hour endurance, and a payload capacity of 210 kg.

To meet growing demand, Milkor expanded its production capacity at its Centurion facility, reaching an annual output of over 3,000 weapons, with potential scalability to 4,000 units per year. The company has also made provisions for additional output if demand surpasses current projections.

The SuperSix has also been adapted for use on vehicle, naval, and aerial platforms. Its versatility allows integration into various operational configurations, extending its battlefield applications. Additionally, Milkor has developed a version designed for riot control applications—the Milkor MAR (Multiple Anti-Riot)—which recently passed its final qualification phase and is now being presented to potential users.

As part of its international expansion, Milkor has opened offices in India, the United Arab Emirates, and Saudi Arabia, strengthening its presence in key markets. Its strategic focus on innovation and the development of new weapon systems aims to meet the evolving needs of the global defense sector. By conducting tests in Colombia, the company seeks to solidify its position in the Latin American market and explore new collaboration opportunities with the region's armed forces.

The Milkor SuperSix MRGL differs from the three U.S.-made 40mm grenade launchers used by the Colombian Army in several key aspects. Compared to the Mk 19, a belt-fed automatic grenade launcher designed for tripod or vehicle-mounted operation, the SuperSix is a portable, hand-held system. The Mk 19 has an effective range of 1,500 meters and fires 40×53mm high-velocity grenades, but it weighs 35.2 kg and is primarily used for sustained fire in static or vehicle-mounted roles. In contrast, the SuperSix weighs 5.96 kg and is operated by a single user, providing greater mobility in scenarios where dismounted personnel require a multiple-shot grenade launcher. While the Mk 19 has a higher sustained rate of fire, its use is limited to specific platforms due to its weight and mounting requirements. The SuperSix, by contrast, offers an alternative for infantry use where a tripod-mounted system is impractical.

When compared to the M79 and M203, both of which are single-shot 40×46mm grenade launchers, the SuperSix has a significantly higher firing capacity. The M79 is a break-action, stand-alone launcher, while the M203 is designed as an under-barrel attachment for rifles. Both systems require manual reloading after each shot, limiting their rate of fire. The SuperSix, with its six-shot rotating cylinder and double-action firing mechanism, can fire all six rounds in under three seconds. Additionally, while the M79 and M203 have an effective range of 350-400 meters, the SuperSix can fire both low-velocity (400 meters) and medium-velocity (800 meters) rounds, providing extended reach. The ability to fire medium-velocity 40×51mm grenades allows the SuperSix to engage targets at greater distances compared to the M79 and M203, which are limited to 40×46mm low-velocity ammunition.
