It was created in the early 80s based on the Ak-74, which in turn was created on the basis of the legendary Ak-47. The task was to create a compact and reliable automatic weapon for arming the crews of combat vehicles.

In fact, the new machine gun was supposed to fill a niche, which in the Western armies was occupied by submachine guns.

Subsequently, the reliability, simplicity and compactness of the rifle as well as the high power of the munition led to its spread throughout the world.

The rifle's operation during firing and reloading is identical to that of the AKM

After ignition of the cartridge primer and propellant, rapidly expanding propellant gases are diverted into the gas cylinder above the barrel through a vent near the muzzle

The build-up of gases inside the gas cylinder drives the long-stroke piston and bolt carrier rearward and a cam guide machined into the underside of the bolt carrier along with an ejector spur on the bolt carrier rail guide

rotates the bolt approximately 35° and unlocks it from the barrel extension via a camming pin on the bolt

The moving assembly has about 5.5 mm (0.2 in) of free travel which creates a delay between the initial recoil impulse of the piston and the bolt unlocking sequence, allowing gas pressures to drop to a safe level

Like previous Kalashnikov-pattern rifles, the AK-74 does not have a gas valve; excess gases are ventilated through a series of radial ports in the gas tube
