Steyr is a 1,000-year-old town located in the northern state of Austria, it is the center of Austrian manufacturing and has a long history, since the 14th century it has been a famous metalworking center, and in the mid-17th century it produced thousands of rifles, cavalry guns and pistols for the Austrian royal army every year.

Austria's unique geographical location allows for the continuation of excellent firearms manufacturing, and although the country is small, it has several well-known arms manufacturers. One is Steyr Manlisha, who created the AUG, and the other is Glock.

In 1977, Steyr Manlisca launched the AUG paratrooper assault rifle, and in 1978 it was officially mass-produced to equip the Austrian Army, followed by ****** ordered AUG to equip its own army, then Oman, Saudi Arabia, and in 85 the Australian Army adopted AUG, followed by Ireland and New Zealand, and AUG was also equipped with law enforcement agencies in many countries around the world.

The design of this gun is very classic, and it has a long service life, beautiful and reliable. It is the world's first stockless assault rifle to be mass-installed, and it has set off a stockless firearm design boom in the field of light weapons in the world, although it is not the first stockless rifle, but it is the most successful one.

The name Steyr is used in the headquarters of several factories in Steyr City, such as the Steyr Arsenal, the Truck Factory, and the Automobile Factory, and although the city is small and has a small population, it is a veritable industrial town.

At present, China National Heavy Duty Truck Group is cooperating with Steyr Heavy Truck Manufacturing Co., Ltd. to introduce Steyr 91 series heavy-duty trucks with a total mass of 16~40 tons, and also introduce supporting ZF gearboxes, steering gearboxes and fuller transmissions, etc., to build a production base with an annual output of 10,000 heavy-duty trucks and 5,000 engines.

This year, Ji. South set up a Sinotruk technology center, absorb and digest Steyr 91 series heavy trucks and supporting equipment, more than 10 provinces of truck manufacturers and related scientific research units have gathered their attention to the country. Nanzhongruk, just waiting for the heavy truck to finish the work, the big guys rushed up to share the fruits of victory.

Of course, Lin Qiangsheng can't do such a tasteless thing, Dongxing wants to share technical achievements, but at least he has to pay some tuition.

Horst Wesper, of the Starman Lische Company, received Lin Johnson and his party, one of the designers of the AUG assault rifle and the designer of the Glock pistol. He was also supervised by Colonel Walter Stoll of the Austrian Military Technical Office, who had overseen the development of the AUG.

Steyr and the Austrian government still attach great importance to this line, and because of the good cooperation between the parent company Steyr-Daimler-Puch and Sinotruk, it is not the first time that Austrians have dealt with Chinese, so everyone is not so strange.

Lin Qiangsheng, Li Weiru and others came directly to the Steyr Arsenal, visited the weapons showroom, and saw the AUG assault rifle that the Austrians were proud of.

Duo Yingxian liked this stockless structure very much, and he said to everyone: "In the future, stockless guns may represent the mainstream of light weapons in the world, and many countries in the world have adopted stockless guns as the main battle weapons!" When he said this, he looked at Lin Qiangsheng.

Duo Yingxian seemed to say to him: "The stockless gun has many advantages, such as shortening the length of the gun without shortening the barrel, reducing the weight, easy to carry, flexible movement, suitable for small caliber, melee combat, street fighting, jungle warfare are more suitable." ”

Wesper was translated, and when he took over, his German accent was very strange, and the translator kept frowning and trying to listen.

"I agree with Mr. Duo's statement that the continuous use of firearms by our AUG users fully proves these advantages, and the overall straightness of the stockless gun is very helpful for maintaining accuracy, and its light weight and good manual efficiency make it very convenient for assault forces or law enforcement agencies!"

Li Weiru nodded to Westper and said, "We in China are also carrying out the design of no gun stock, and we hope to learn from your successful experience." ”

He thought that this was one of the main designers of AUG, and if he could reveal some technical details, it would be too important for their research, and Duo Yingxian on the side also thought about it.

Westper said generously, "No problem, we can discuss it." ”

Duo Yingxian was overjoyed and immediately asked him, "Excuse me, what is the design idea of the AUG assault rifle?" ”

"The program actually began in 1960 to replace the FNFAL automatic rifle, and the military demanded an assault rifle with no less accuracy than the former, reliability not less than AK, weight no more than M16, and no longer than a modern submachine gun, and a multi-purpose weapon with a rifle, carbine, and submachine gun," Wesper said.

After all considerations, we felt that the stockless design could better reflect these requirements, and there were already many mature design ideas for automatic rifles at that time, so we took these concepts, such as stockless design, modularization, and a large number of aluminum alloys, engineering plastics to reduce weight, and the use of many modern composite materials instead of metal materials.

In short, it's a clever combination of previously known design concepts, and these are integrated into our AUG, and it turns out that it is so good! ”

Wesper looked at everyone with a smile, slightly stunned, and found that these Chinese did not react much.

Lin Qiangsheng applauded and said: "Well said, applying mature and advanced concepts to weapons, AUG combines the advantages of many automatic rifles, coupled with its genius design style, to create a classic famous gun!" ”

Wesper thanked Lin Johnson, and he breathed a sigh of relief, this young man was the other party to the cooperation, and it seemed that he was satisfied with Steyr's technology.

Duo Yingxian was slightly disappointed, Weisper did not say what he wanted, he felt that this Austrian was the same as Eugene Stoner, the designer of the M16, and Karanishkov, the designer of the AK47, and would not tell the real thing to the Chinese at all.

Lin Qiangsheng said to everyone: "I think that the design of firearms depends on technology for three points, talent for seven points, and inspiration that flashes by chance!" ”

Wesper stretched out his thumb, nodded and said, "Mr. Lin, you're right, talent and inspiration, I think inspiration is more important, technology can always solve it, but to design a classic firearm, it's not just about technology!" ”

"Not really!" Duo Yingxian muttered a little unconvinced, he was bent on finding out the technical loopholes of these famous guns, and he could not compare with these foreign masters in terms of design, only by starting from the technology to see if these guns had any shortcomings, he also knew that only in this way could Chinese light weapons have a way out.

Then everyone went to the gunsmith factory, visited the CNC cold forging machine tool for processing the barrel, we saw a barrel blank was grabbed by the manipulator, and then reversed on the mandrel, the outer surface of the mandrel is engraved with the lines corresponding to the rifling of the barrel, after the hammer forging tens of thousands of times, the rifling is processed on the inner surface of the barrel.

At the same time, the outside of the machined barrel is also engraved with the spiral pattern left by cold forging, which is the sign of the cold forged barrel, but some countries specially grind this pattern away, and AUG retains these patterns, which is very beautiful.

"The use of cold forging improves bore finish, dimensional accuracy, surface strength, extends the life of the barrel, improves the gun's shooting accuracy, and facilitates the machining of a conical barrel that can reduce mass," said Wesper. The cold forging process was first proposed by Steyr Corporation, and now many light weapons companies in the world have adopted Steyr's cold forging machine tools. ”

Everyone sees that this kind of machine tool is indeed advanced, this kind of manipulator is completely automated, only need to enter the program, no need for manual labor at all, saving time and effort.

But Westper also said to everyone: "However, it should be noted that compared with other methods, cold forging has the most energy on the barrel blank, and its deformation amplitude is also the largest, and the structural damage to the metal material is also the most serious, and it will accumulate more stress, so it requires very fine heat treatment to release."

This manufacturing method is not conducive to ensuring maximum accuracy, if it is an ordinary rifle, machine gun using this method of processing the barrel is of course very suitable, but if it is to pursue the ultimate accuracy, the cold forging method has inherent shortcomings, at this time will generally choose the barrel manufactured by the cutting method.

The cost of cold forging equipment is high, but its processing cost is very low, the life of the equipment and barrel is the longest among several processing methods, and the follow-up processing time is also the shortest. ”

Li Weiru nodded, and Lin Qiangsheng said: "The introduction of cold forging machine tools, you have to introduce the corresponding heat treatment technology, and listen to Mr. Westper's statement that this set of equipment is very expensive, it must be more expensive than the kind of precision forging machine introduced in Sichuan Province, this is fully automated!" ”

Lin Qiangsheng said: "I consulted them about this, there is no problem with the introduction of costs, the key is other supporting technologies, whether the Austrians are willing to sell to us." ”

Li Weiru said: "That's why you prepared so many materials to negotiate with Steyr?" ”

Lin Qiangsheng said with a smile: "No need to be in vain, of course it is best to make the Austrians happy!" (To be continued.) )
