The GP-30 underbarrel grenade launcher is intended for destroying manpower in open country or in uncovered trenches/foxholes, as well as on reverse slopes by direct and indirect fire, using the VOG-25 and VOG-25P caseless fragmentation rounds.

Being muzzle-loaded, the GP-30 enables to increase practical rate of fire 2-3 times compared with the US 40mm M203. The trigger mechanism is of double action.

The grenade launcher comes equipped with a leaf sight, which is used to correct grenade drift. Unlike the GP-25, the sight is mounted on the right side and requires no range adjustment.

 

The standard version of the grenade launcher is mounted on the following assault rifles of Russian production: 5.45mm AK-74 (AKS-74), AK-74M, 7.62mm AKM (AKMS), 5.56mm AK-101 and 7.62mm AK-103. It can be modified for attaching to other assault rifles.

The grenade launcher can also fire non-lethal rounds.
