Type 57 heavy machine gun was produced and finalized in 1957, and a large number of troops were equipped, and then it was replaced by Type 67 light and heavy machine gun. Type 57 heavy machine gun is an improvement of Type 53 heavy machine gun. The wheel frame of Type 53 heavy machine gun is mainly changed to frame wheel frame. The barrel is 2 mm longer than Model 53, and there is a longitudinal cooling groove on the outside. The power is unchanged, and the weight of the whole gun is reduced from 44.5 kg to 38 kg.

In the 1962 Sino-Indian border self-defense counterattack, the Type 53 heavy machine gun used by our army used a heavy wheeled gun rack, which was too bulky and was very unfavorable for mountain operations. Sometimes, in order to install guns on the hillside, other soldiers have to set up wheels on their shoulders.

Affected by this lesson, 1965, the type 57 heavy machine gun was changed from a frame wheel frame to a tripod, and the weight was reduced to 29 kg. In the self-defense counterattack against Vietnam, the Type 57 heavy machine gun has become an important equipment of our army, which has been tested in actual combat and performed very well.
