GP-25

The GP-25 Kostyor ("Bonfire"), GP-30 Obuvka ("Footwear") and GP-34 are a family of Russian 40 mm under-barrel grenade launchers (Granatomyot Podstvolnyj) for the AK family of assault rifles. They were first seen by the west in 1984 during the Soviet Invasion of Afghanistan. The GP-30 was lightened and the redesigned sighting system was moved to the right.

The current Izhmash-made version, the GP-34, has an again redesigned sighting system on the right and features the following advantages:


 * Reliability: It is designed and tested specifically for the Kalashnikov assault rifles, fits such assault rifles directly without any adaptors or forearm dismantling.
 * Improved safety: The design prevents a round from moving within or falling out of the barrel, even if the muzzle is pointed down. The GP-34 features an additional mechanism (firing pin safety lever) to improve safety during loading.
