The 3GL is the first semi automatic, multiple shot 40mm grenade launcher specifically designed to be mounted under a conventional assault weapon. By using Metal Storm’s patented technology to stack multiple rounds into a barrel and fire them electronically, the 3GL dispenses with mechanical loading mechanisms, resulting in a light, simple, powerful infantry weapon that will multiply a soldiers’ effectiveness on the open battlefield and in urban combat.

By providing 3 shots instead of 1 before reload, the 3GL triples the “first-response” grenade firepower of a squad or platoon. This can have a dramatic impact in a firefight, where each soldier can deliver three high explosive (HE) or enhanced blast (EBX) grenades onto a target without reloading, whilst still being able to fire his automatic rifle.

The Metal Storm 3GL is now a fully integrated, fully functional prototype weapon. The video footage documents recent live firings using, and explosive, spitback and inert warheads at firing ranges in Singapore and Australia.

The video includes semi-automatic firing of 3 shots, firing HE and EBX warheads at a range of 50 metres, man firing from the shoulder using the 3GL shoulder stock, and the unique stacked round loading and unloading process.

The development of the 3GL weapon system is proceeding on schedule. Further refinement of the weapon is currently underway at the Metal Storm engineering facility in Queensland, Australia.
