GP-25 is a Soviet 40mm underbarrel grenade launcher designed to mount to AK-pattern rifles such as the AKM. It is a muzzle-loading launcher that fires VOG-series 40mm grenades and uses a simple ladder-style sighting system. It is best known for being the standard Soviet/Russian underbarrel grenade launcher family in 40mm “caseless” ammunition, distinct from Western 40×46mm systems. In Military Conflict: Vietnam, the GP-25 appears as a Zombie mode exclusive weapon.
HISTORY
Development of a rifle-mounted grenade launcher for the AK platform began in 1966 at TsKIB SOO and continued through the 1970s, culminating in the GP-25’s acceptance into Soviet service in 1978. The GP-25 became the main production model, with later refinements leading to the GP-30, which reduced weight and revised the aiming system. The launcher mounts under the rifle’s barrel via dedicated hardware and is intended to provide organic explosive capability to infantry at short-to-mid ranges.
The GP-25 fires Soviet 40mm VOG-25 high-explosive fragmentation grenades (and related types) with a maximum range around 400 meters and a typical effective employment range around 150 meters. Its ammunition differs from Western 40×46mm grenades used in breech-loading systems like the M203: VOG-type rounds incorporate their propellant/primer in the base of the grenade so nothing is extracted after firing, allowing rapid reloading from the muzzle. The GP-25’s barrel life is commonly cited at roughly a few hundred rounds in service documentation and reference works.
