QJZ-89

The QJZ-89, also known as the Type 89 heavy machine gun, is a heavy machine gun designed in the People's Republic of China which fires the Soviet 12.7×108mm ammunition.

Astonished by the apparent capability of the NSV, Chinese designers began to develop a comparable weapon system.

Only after the development had concluded did they realize the 25 kg (55 lb) weight figure did not include the tripod.

[2] The weapon features a hybrid gas and recoil operated action.

[4] The QJZ-89 has low weight through a combination gas/recoil action usually seen on autocannons, where gas unlocks the breech while recoil operates the feed and decreases the peak recoil forces induced on the housing and mount.
