8 1 automatic rifle is a standard rifle developed in China in the early 1980s, which is widely used in China People's Liberation Army and some foreign armies. The gun family started research and development from 1979, 198 1 finished the design, and 1983 started mass production.

Its main purpose is to provide a transition weapon before equipping a small caliber automatic rifle. Although the 8 1 gun family still uses 56-type 7.62MM bullets, its performance is very good.

The gun family includes 8 1 automatic rifle, 8 1-kloc-0/automatic rifle (also known as Bayi bar) and 8 1 7.62mm light machine gun, among which, 8 1 automatic rifle uses wooden fixed stock and 81automatic rifle. The main structures of these three weapons are the same, and the air guide system and ammunition supply of automatic machine, recoil mechanism and firing machine 8 can be interchanged within the gun family, so that a total of 65 parts can be interchanged for general use, and the general rate of other parts can reach 70%.

The appearance of this kind of gun family greatly facilitates training, use and maintenance, which not only strengthens the combat effectiveness of the combat detachment, but also provides conditions for the exchange of firearms and the enhancement of firepower.

However, the 8 1 gun family also has some shortcomings. The appearance is similar to that of Type 56 assault rifle, lacking innovative application of new structure, new technology and new materials. This shows that the gun manufacturing industry in China was still in the early stage of development and needed further improvement and perfection.

To sum up, the 8 1 automatic rifle is an important rifle developed in China in the early 1980s, which has the advantages of excellent performance and convenient use. Although there are some shortcomings, it has a positive role in promoting the development of China's gun manufacturing industry, and also provides valuable experience for the follow-up rifle research and development!
