The Glagolev-Shipunov-Gryazev GShG-7.62 is a four-barreled rotary machine gun designed in the Soviet Union, similar to firearms such as the M134 Minigun. It is a hybrid weapon using both propellant gas and an electric drive to rotate the barrels, which is in contrast with most other rotary guns (that are often exclusively powered via an electric drive). It was developed in 1968–1970 for the Mi-24 helicopter together with YakB 12.7mm machine gun, and is currently used in GUV-8700 gun pods, and flexible mounts on Kamov Ka-29.
