Kalashnikov grenade launcher

All AK-47 type rifles can mount a cup-type grenade-launcher that fires standard RGD-5 Soviet hand-grenades. The soup-can shaped launcher is screwed onto the AK-47's muzzle.[1][2] To fire, first insert a standard RGD-5 hand-grenade into the launcher and then remove the safety pin. Second, insert a special blank cartridge into the rifle's chamber. Third, place the butt-stock of the rifle on the ground and fire from this position.[1] The maximum effective range is approximately 150 meters.[1] This cup-type launcher can also be used to launch tear-gas and riot control grenades.
