The MGL ("Multiple Grenade Launcher") produced by Indumil of Colombia is the locally-licensed form of the popular South African MGL Mk 1. The Mk 1 variant appeared in 1996, succeeding the original MGL Y2 offering of 1983 and went on to be adopted as the "M32" by the United States Army and as the "RBG-6" by the Croatian Army among others. In its Colombian guise, the system retains its robust, reliable capabilities centered around a Western-standard 40mm anti-infantry grenade projectile firing through a six-round rotating ammunition cylinder. The action is semi-automatic where one trigger pull equals one projectile fired with a Double-Action (DA) design.

Indumil introduced their version of the MGL in or around 1995 and has since brought to market an array of capable infantry arms alternatives including the Cordova 9mm semi-automatic pistol (detailed elsewhere on this site), an offshoot to the famous Israeli GALIL assault rifle under the "Galil-C" name (detailed elsewhere on this site), associated carbine forms, portable infantry-level mortars, and infantry hand grenades.

The MGL has an overall length of 740mm (29.1") though the hinged, fold-over shoulder support reduces this to 640mm (25.1") when collapsed onto the frame (the frame being completed in a non-reflective matte black finish). The barrel assembly measures 300mm (11.8") and is rifled with a right-handed six-groove pattern featuring 1:47" twist. The top of the receiver mounts a sighting devices for more accurized ranged fire with stepped increments of 25 meters, 50 meters, and 375 meters; projectiles can reach beyond 400 meters though with a reduction to accuracy. Weight is 6.13 kilograms when the six grenade chambers are empty.

Rate-of-fire reaches 18 rounds-per-minute when firing 112mm or shorter projectiles. Supported projectile types include both 40x46mm and 40x51mm grenades.

The arrangement of the system is largely conventional and faithful to the South African design; an angled pistol grip is featured integrated to the ringed trigger unit found under the aft-end of the frame. The rotating, revolver-type spring-loaded magazine is positioned at center with the top-most chamber aligning with the tubular barrel protruding from the front of the weapon. The sighting device (if equipped) and folding shoulder stock are both connected at the top of the receiver. A foregrip is added under the barrel for a firm, two-hand hold of the system.©MilitaryFactory.com
