B'Tselem report: Crowd Control: Israel's Use of Crowd Control ...

• A six-grenade launcher, manufactured by Combined Systems, Inc. under thebrand name Penn Arms Launcher. The model used by Israeli security forcesis L640-1, 21 and is nicknamed Ringo or Tupi (Revolver), because it includes aspring-advance magazine drum with a six-shot capacity, in which six grenadecartridges are loaded before firing. As each grenade is fired, the drumrevolves and loads the next grenade into the launcher’s chamber in a firingreadyposition, enabling the firing of six grenades in quick succession.All the launchers have the same firing mechanism: Pulling the launcher’s triggerstrikes a cap that activates both the trajectory mechanism, which launches thegrenade at the target, and the gas-dispersal mechanism. All three launchers havea rifled barrel, which provides spin for some types of grenades, thus stabilizingtheir trajectory. 22Soldiers firing aluminum tear-gas canisters from a 40mm launcher, a-Nabi Saleh.
