The GP-30 Obuvka ('Shoe'), GP-25 Kostyor ('Bonfire') and BG-15 Mukha ('Fly') are Russian under barrel grenade launchers for the AK-series of assault rifle. They were first seen by the west in 1984 during the Soviet Invasion of Afghanistan. The initial version was designated BG-15, and was fitted under the barrel of AK-74 assault rifles. The main production version, the GP-25 has a different sighting system. The latest version, the GP-30, is an evolved version of the GP-25, being lighter, easier to make, and easier to use. The GP-30/GP-25 is used by the MEC and PLA assault kits.
