The 40x46 mmRBG 40mm/6 M11 launcher is a lightweight semi-automatic, shoulder fired grenade launcher for infantry use.
It fires the widely used 40mm, low velocity family of grenades.
The weapon is based on the revolver principle with a spring-driven gas operated cylinder.
The 40x46 mm Grenade Launcher is fitted with an Occluded Eye Gun sight, which means that the weapon is fired with both eyes open.
One eye looks into the sight, and the other eye then has an unimpeded view of the target.
The sight is operational in poor light conditions as long as the target can be seen.
The sight is calibrated in 25 metre increments, from zero to 375 meters.
