In the 1970s and 1980s, many air-operated firearms were widely spread on the market at that time, not only the I-Jinjiang, but also the Emei Sanjian and other air rifle brands with different qualities and forms. These air rifles are mainly lead bullets, mainly shooting entertainment or hunting birds. Although they are not very powerful, they also have a degree of danger and cause huge losses to birds and even rare birds. , So the ban on air guns is also a matter of reason.
In that era, the "Xing" brand air rifle, which had the same name as I-Jinjiang and other well-known brands, can also be said to be a relatively good firearm, but the "Xing" brand has a more famous name, "Double Sword" , And many people call it "Double Arrows." Beijiang Machinery Factory, which produces this star brand air rifle, was an enterprise with an official code name. From the beginning of production, it used Type 56 semi-automatic rifle as its main product. Participated in the development of the 56-type semi-automatic rifle with an all-plastic buttstock. Logically speaking, this type of airgun has inherent advantages in quality and performance. The most representative of the
star brand is the X-904 air rifle. The outer diameter of the gun is 12 mm, the length of the gun is 510 mm, the barrel is long, muzzle velocity and accuracy are more prominent than similar products. The compressor has an outer diameter of 22 mm and an inner diameter of 18 mm. The air compressor handle is in a conical shape. From the overall appearance, the body of the gun is relatively short. If you compare
, Xingpai and Sanjian air rifles have the most similar appearance and structure. The barrel size of the two air guns is even the same. The difference between the two is mainly concentrated in the compressor, air chamber, and valve sleeve. And sights and other places. Because the outer diameter of Sanjian's compressor cylinder is 20 mm, the inner diameter is 17 mm, and the star brand is very different, the internal compressor cups, pistons and other parts cannot be interchanged. Moreover, the star compressor connecting rod components are all steel Made parts are stronger and more durable than Sanjian’s steel/nylon composite structure. The reason
gave birth to the birth of Xing brand air guns is that most of the main products of the manufacturer's five or six semi-automatic rifles were replaced and abolished, which led to a significant reduction in military production tasks. Therefore, the machine factory began to trial production of civilian products, even I also produced sewing machines and other products before starting to produce air rifles. The initial "Star" brand was marked with a five-pointed star. After the name was changed to "Double Sword", some models still had the five-pointed star logo.
has produced spring air guns in addition to the launch of the compressed air gun star brand. Launched at the same time as the earliest X904 air gun, there is a spring-open air gun model X902. It is said that in its later period, it also produced a relatively advanced hammerless compressed air gun at the time. It adopted a valve loading design, that is, there is an aluminum loading block above the loading port. After opening it, it is loaded with lead bombs and then loaded. When the block is put down, it will be automatically locked, and you can shoot directly after it is full. The last star of
is the Double Sword Airsoft gun, which was born in 1992 and adopts the principle of side tie rod energy storage. The special feature is the use of a rather strange inverted "L" type side folding buttstock, but the specific data performance is not And know.
It is said that the main reason for the tepidity of the double swords is that their series of product specifications are not uniform and universal, and the accessories of each model are more difficult to find. The manufacturing process of each gun type is also very unstable. The quality of the products varies from good to bad, so compared to well-known brands such as I-Emei, they are lacking a lot.
