Chapter 48: Aren’t you afraid of any danger?
As many people don't know, among the various firearm structures such as the buttstock, magazine, barrel, piston, bolt, firing pin, trigger, recoil spring, gas port, safety sear, magazine catch, muzzle brake, etc., why is the "barrel" the most difficult to make?

Because as an important component of a firearm, the barrel goes directly through the chamber. On the battlefield, when the bullet is fired, the expanding gas generated by the explosion of gunpowder or the explosion of the gunpowder will push the bullet through the barrel, becoming a high-speed projectile and ultimately hitting the enemy target.

If the high-kinetic-energy bullet cannot slide out of the barrel smoothly after the soldier pulls the trigger, it will cause a "barrel explosion", which is potentially fatal.

Therefore, the material of the barrel is crucial. However, after the material problem is solved, the barrel still needs to face the test of fine and rigorous manufacturing technology. Not only does it need to consider a large number of details such as the firing pin and linkage fitting points, but it also needs to machine fine rifling on the inner wall of the barrel, which is already very thin.

The rifling can be said to be the soul of the gun barrel. It is precisely because of it that the bullet is given the rotational force, so that after the bullet leaves the barrel, it can still maintain the predetermined direction and hit the target!
Rifling is so important, but Wang Duoyu, an amateur player, insisted on straightening it himself. He clearly said that straightening the rifling inside the barrel requires very demanding skills. Why didn't he have the self-awareness to insist on doing it himself?
After the rifling was destroyed, the barrel was also completely destroyed and could only be remade, so Kong Lingxian was so angry. However, what he never expected was that Secretary Chen Mingzhang actually openly protected Wang Duoyu.

"Director Kong, what's wrong with you? Didn't you see Comrade Xiao Wang doing research? Can't you figure out this technology by doing it yourself? If you don't understand something, don't talk nonsense here. Okay, if you don't have anything else to do, go do your own thing and stop giving orders blindly."

Kong Lingxian was stunned and looked at Secretary Chen in disbelief, but the latter glared at him impatiently, so he could only leave in shame.

During the whole process, Wang Duoyu was hesitant to speak, then retracted his surprised look and prepared to continue working. However, the rifling had been completely straightened at this time, and after inspection, it could finally be assembled and tested.

Wang Duoyu couldn't sit still when he heard this. Straightening the rifling was too boring, how could it be as fun as testing a gun? Besides, testing a gun was also a way to practice shooting. He wouldn't miss such an opportunity.

As for whether testing such new firearms would lead to dangers such as barrel explosion, there would definitely be dangers, but Wang Duoyu watched the entire manufacturing and quality testing of these firearms parts, and they were all fully qualified products. How could he still worry about the dangers?
"Lao Lin, you're just going to let him test the gun like this? Aren't you afraid of any danger?"

In the empty shooting range, when Wang Duoyu was busy putting on protective gear and preparing to test the gun with excitement, Chen Mingzhang frowned and touched Lin Dehong with his shoulder, nodded in the direction of the former, and even changed the way he addressed him.

Xiao Linzi was an inappropriate name. When Chen Mingzhang called him Lao Lin, Lin Dehong should have paid attention. However, when he heard that Wang Duoyu might be in danger when testing firearms, Lin Dehong shook his head and said:

"Guess why he and I are connected? If he hadn't told us he'd designed a firearm and wanted us to introduce him to a firearms research institute, you wouldn't be here right now."

"Uh, why is that?" Chen Mingzhang was stunned. Lin Dehong simply repeated what Wang Duoyu had mentioned to him before about why he liked guns, and then continued:

"As a young man, he was very interested in firearms. If it weren't for his interest in firearms, I'm afraid we wouldn't be seeing such a well-improved assault rifle, or even other weapons."

Just as the two began to whisper, several people appeared in the distance. Kong Lingxian was in the lead, leading two people and walking quickly towards Chen Mingzhang and Lin Dehong. Before they even got close, Chen Mingzhang had already extended his hand to greet them, laughing. His enthusiasm surprised Lin Dehong. Soon, after Chen Mingzhang exchanged pleasantries with the newcomers, he brought the two over and introduced them to Lin Dehong.

"Oh, Secretary Chen, I heard from Director Kong that you're testing the barrel of a firearm, right? Can I watch?"

"Professor Lao, you're right. Of course you can observe. We'd love for you to guide our work, so how could we not let you observe? We'd even like to ask you for advice on how to improve the manufacturing process for gun barrel materials."

Chen Mingzhang spoke with a smile, his expression somewhat flattering, because the Lao Yuanchang in front of him was no ordinary person. He was an expert in mechanical engineering and materials science at Harbin Institute of Technology. He was the person in charge of some material projects such as the Type 59 tank and the Y-10 jet airliner, and he also participated in the research of some materials for the Type 63 automatic rifle.

We need to know what happened in the past ten years, but Lao Yuanchang, as a professor at Harbin Institute of Technology, was not affected by it at all. In addition to Harbin Institute of Technology itself, he himself was a native professor and, like Yu Min, had never been abroad.

"Oh, I just heard Director Kong talk about it, but I'm not very clear about the details. In that case, Secretary Chen, could you tell me the specific technical parameters of your barrel material?"

Lao Yuanchang immediately pushed the glasses on his nose. His myopia of more than 600 degrees forced him to wear these heavy glasses every day. The thick lenses and frames together pressed a deep dent on his nose.

Upon hearing this, Kong Lingxian looked at Chen Mingzhang with an eager look, but at this time, Wang Duoyu had already opened fire. The gunshot attracted everyone's attention.

Wang Duoyu was very excited. He changed the magazines continuously and emptied all six magazines. However, he did not feel much recoil and his body still did not feel tired.

In addition, after emptying the six magazines, he asked the guard next to him to help compact the bullets in the magazines. At the same time, he had disassembled the barrel and began to check the rifling, firing pin, recoil spring, etc., and found that they were almost the same as new ones, which shows that these materials are very hardcore.

On the other hand, this also illustrates one point, that is, the firearm he designed and improved is indeed awesome. It was originally designed to fire 12000 rounds of bullets, but if it is well protected, it may have a lifespan of rounds.

"Xiao Wang, how is it? Is the barrel still hot? Are the rifling and other parts worn out?" Lin Dehong's voice floated over, followed by Lao Yuanchang's question:
"Hello, young comrade. Did you design this barrel? What material is it made of?"
