The GP-34 underbarrel grenade launcher (GRAU index 6G34 – 6Г34) is an evolutionary development of the previous GP-25 and GP-30 models. It’s designed and manufactured by the IZHMASH factory (which is now a part of the “Kalashnikov” Concern). It can be installed on the Kalashnikov AK-74M, AK-101 and AK-103 assault rifles, as well as on some similar models of foreign make. It’s in current service with the Russian military and special police (SWAT-type) units.

The GP-34 grenade launcher is a single shot, muzzle-loading weapon with rifled barrel. It uses all types of 40mm VOG-25 type grenade rounds with propellant chamber (case) integrated into the body of the grenade. Trigger is of Double Action Only type, with manual safety and additional automated safety measures. This launcher is equipped with adjustable iron sights that are located on the right side of the weapon.
