About
What it is, and why it matters
The Milkor SuperSix MRGL is a South African six-shot 40mm multiple round grenade launcher built around a spring-driven revolving cylinder with a double-action firing mechanism. It chambers 40mm less-lethal, 40mm low-velocity (40x46mm) and 40mm medium-velocity (40x51mm) natures, letting a single operator place six aimed grenades on target in as little as three seconds out to roughly 400 metres with low-velocity and 800 metres with medium-velocity ammunition. A progressively rifled barrel, STANAG 4694 NATO accessory rail and multiple sighting options make it Milkor's flagship high-precision 40mm launcher.
Milkor pioneered the spring-driven six-shot 40mm revolving grenade launcher in South Africa in the 1980s; the SuperSix MRGL is the company's modern evolution of that concept, adding medium-velocity reach that roughly doubles effective range over the original low-velocity MGL.
Overall length is quoted by the manufacturer as 781 mm/859 mm with the compensator fitted and 746 mm/824 mm without it, reflecting the collapsible stock. The barrel uses progressive rifling with a final twist of one turn in 1200 mm (1:47.24 in).

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
