In 1979, acting on directives from higher authorities, a requirement was issued to develop a 7.62mm squad weapon family. Initially, the requirement called for the family to include three types of weapons: an automatic rifle, a submachine gun, and a light machine gun. Later, this was revised to consist of an automatic rifle (combining the roles of a rifle and a submachine gun) and a squad light machine gun. This weapon family was designed to fire the various types of 1956 pattern ammunition and was intended to replace the Type 56 semi-automatic rifle, Type 56 submachine gun, and Type 56 squad light machine gun then in service.
At the time, the units accepting the task of developing the 7.62mm squad weapon family were divided into three development groups to conduct simultaneous research. This article introduces the "Type 82" family developed by the China Ordnance Industry 208th Research Institute.
Development of the Type 82 family began in January 1979. By October of the same year, prototype guns participated in selection trials at the State Range and the Lanzhou Military Region Infantry School, achieving excellent results. In October 1981, the weapons passed the state design finalization tests. The conclusion of the trials was as follows: The main specifications and dispersion accuracy of the weapon family basically met the tactical and technical requirements; the processing and assembly of parts basically met requirements, as did the regulations for interchangeability. The automatic rifle’s mechanism was reliable under various operating conditions. The light machine gun was reliable under most conditions, except for one gun that experienced frequent "failures to return to battery" during the river water immersion test. Comprehensive service life testing showed little change in caliber, muzzle velocity, or dispersion accuracy; the failure rate was low; and main parts (such as the bolt, receiver, and recoil mechanism) showed no breakage, meeting tactical and technical requirements. Overall, the automatic rifle met the requirements and was ready for finalization.
Although the light machine gun experienced malfunctions during the river water immersion test, according to firearms testing regulations and combined with China's historical testing protocols for special conditions light machine guns were historically never subjected to river water immersion tests. Based on the spirit of the "Minutes of the Technical Review Meeting for the 7.62mm Squad Weapon Family," jointly convened by the General Logistics Department Armament Bureau and the Scientific Research Bureau of the 5th Ministry of Machine Building from June 17–20, 1980, the results of the light machine gun's river water test were for reference only. Given these circumstances, it was determined that the light machine gun also met the conditions for design finalization.
Structural CharacteristicsTo meet the tactical and technical specifications, the Type 82 family adopted the following technical measures:
(1) Weight Reduction The receiver assembly utilizes a combined stamping and riveting process. Materials were selected rationally, prioritizing low-density materials available at the time. Emphasis was placed on reducing the mass of individual parts and reducing the total number of parts by designing components to perform multiple functions. The structure was arranged compactly to minimize external dimensions.(2) Ensuring Accuracy Measures included: ensuring the coaxiality of the automatic mechanism, receiver, and bore axis; designing the bolt carrier to delay the depression of the hammer; ensuring the impact surface of the bolt carrier against the barrel extension (trunnion) upon return is as close to the bore axis as possible; minimizing the distance between the gas system and the bore axis; adopting a symmetrically load-bearing locking mechanism; limiting the lateral wobble of the bolt carrier during the initial phase of recoil; ensuring sufficient strength and rigidity of the receiver; appropriately increasing the volume of the gas chamber; adding a "5th cone" to the chamber to allow the bullet to enter the rifling more accurately [see Note]; utilizing a two-stage trigger and reducing trigger pull weight; increasing the inertial stroke of the piston; and rationally positioning the grenade launcher.
(3) Ensuring Part Strength Part strength plays a crucial role in the design of infantry automatic weapons and is the basis for evaluating whether a new weapon's service life meets requirements. To improve the strength and lifespan of moving parts, the design of the gas system shortened the distance from the gas port to the breech end of the barrel. Simultaneously, to reduce the theoretical rate of fire, the initial volume of the gas chamber was expanded. This caused the pressure in the gas chamber to rise more slowly, reducing the velocity of the automatic mechanism as it recoiled to the rear, thereby lessening the impact of the mechanism at the end of its travel. This is highly beneficial for the smooth operation of the automatic mechanism. The gas regulator features three gas ports to extend the weapon's service life. The structural design of the parts is rational, utilizing appropriate materials and heat treatment processes.(4) Reducing Malfunctions Ejection requires sufficient energy. To resolve issues with the Type 82 family regarding failure to eject and stovepiping, measures were taken primarily to reduce unnecessary energy loss, ensuring ejection is tight and stable, with appropriate ejector positioning and impact points. Additionally, multiple measures were taken to resolve issues with the drum magazine.

The weapon family possesses the following technical features: Novel, simple, and compact structure; aesthetically pleasing appearance; rapid field stripping and reassembly; good mobility and ease of carry; a trigger mechanism designed as a single integral unit (unique to this family), allowing for quick assembly; and a high degree of interchangeable parts. Among the three competing weapon families developed simultaneously, this one had the highest ratio of commonality (71% for parts, 68% for sub-assemblies) and was the lightest in weight.
When the development task was accepted, higher authorities issued two specific stipulations: First, the feed device used by the light machine gun must be the drum magazine from Factory 9396; second, the connection form of the automatic rifle's folding stock must match that of the Type 56-2 submachine gun.
>>64753039I wonder why it is little known.
The 208th Institute executed these instructions, but malfunctions occurred during testing, primarily due to the drum magazine. First, high resistance in the drum caused the light machine gun to experience eight "failures to return to battery" during the river water immersion test—double the allowable number. Another issue was the drum's tendency to cause rounds to pop out; during firing, "jumping rounds" occurred frequently.
To cite a specific instance: During accuracy testing of the light machine gun at the State Range, a fully loaded drum was placed flat on a somewhat unstable table at the site. Someone inadvertently bumped the table, and as a result, every single round in the full drum fell out. This occurred in November 1980 during the design finalization trials the same year the Type 81 family was undergoing its design finalization. At the time, the development staff realized that continuing the trials would undoubtedly lead to a failure rate exceeding the limits, defeating the purpose of the finalization test. Consequently, the researchers withdrew from the test to continue improvements.
The following year, the development team returned to the State Range for a second round of design finalization trials, which they ultimately passed. Although approved by relevant state departments in 1984, the timing was later than that of the Type 81 family. As a result, it was not fielded for service, nor did the state officially name it.
Where did the name "Type 82 Squad Weapon Family" come from?Since the Type 81 family passed its design finalization tests in 1980 and was officially named the "Type 81 Squad Weapon Family" by the state, and this family passed its tests in 1981 (closely following the Type 81), the designers designated it the "Type 82 Squad Weapon Family." This family was never fielded and served only as a technical reserve. This is the reason why the Type 82 family remains so little known.[Note] Chamber: Refers to the enlarged rear section of the gun barrel. The chamber of pistols and submachine guns generally consists of 2 to 4 cones (tapers). The function of the cones is to ensure the correct positioning of the cartridge upon firing and to allow the bullet to smoothly embed into the rifling as it moves forward. Some guns add a "5th cone" in front of the 4th cone to reduce the resistance of the bullet embedding into the rifling and to lower the maximum chamber pressure.
