GP-34 underbarrel grenade launcher

The GP-34 is a Russian 40 mm single-shot underbarrel grenade launcher developed by Izhmash / Kalashnikov Concern as an evolutionary improvement over the GP-25 and GP-30. It uses VOG-25-family grenades, mounts on modern Kalashnikov rifles including the AK-103, and remains in Russian service with military and special police units.

In the Boko Haram Insurgency context, available open-source evidence is limited: the specific AK-103-2 identification comes from visual reporting of Boko Haram militants around Lake Chad, while separate Nigerian court reporting documents alleged AK-103 rifle trafficking from Diffa toward a Boko Haram recipient.

The 7.62 x 39 mm RPK paralleled the AKM, while the 5.45 x 39 mm RPK-74 followed the AK-74; both remain relevant in the Russia-Ukraine War because legacy Soviet and Russian stocks continue to appear in front-line small-arms holdings.
