It is an automatic rifle developed during the Soviet era, an improved version of the AK-47, and officially entered service in 1974. Using 5.45 × 39mm small caliber ammunition, this ammunition has a higher initial velocity and smaller recoil, making shooting more precise. This gun inherits the reliability and durability of the AK series, while making multiple design improvements to enhance shooting accuracy and range. The gun barrel is relatively long, with an effective range of up to 400 meters, and it is lightweight and easy to carry. Widely used in the military of the Soviet Union and its allies, and played an important role in multiple conflicts and wars. It is still adopted by the armies of many countries today.
