Anti-Japanese War, weapons designer at Fengtian Arsenal

"This... you drew it?"

The old fireman turned the blueprint over and over and looked at it, exclaiming in amazement. The famous AK47 made this guy stunned.

Li Qinwu felt proud but also a little embarrassed. After all, he copied other people's things, and now it felt like stealing when he took it out.

"Old man, can you tell me whether this thing can be made with the technical level of the factory?"

Unexpectedly, the old man hesitated for a long time and shook his head.

“I’m afraid not, you’re dealing with something very new, something between a machine gun and a submachine gun.

It's a good idea, but it's very likely that we'll lose the mobility of the submachine gun and the range and accuracy of the machine gun."

Li Qinwu sighed helplessly. As a senior technician in the era of bolt pulling, it was normal for Lao Huotou to have such thoughts.

In this era, let alone automatic rifles, even submachine guns and light machine guns are still in the exploratory stage. Automatic rifles are really too advanced.

The old man tapped the parts on the blueprint with his pipe, pointed at them one by one and said, "Look, you made the gas tube so thin, it will be very difficult to produce. The price of such a gas tube is probably twice that of the gun barrel.

And what kind of ammunition does your gun fire? Pistol or rifle? If it fires pistol, what's the difference between this gun and a submachine gun? If it fires rifle, then the gun will go up in smoke when it's in burst mode.

I have another question. You said the magazine can hold 30 rounds of bullets. Boy, do you understand how high the strength requirements of the magazine are for 30 rounds of ammunition?

The current submachine gun magazine generally has less than 20 rounds. Do you think those foreigners who play with submachine guns don't want more bullets in their guns? They are just afraid that there will be problems with the magazine feed. If the magazine does not feed smoothly, it will easily cause death on the battlefield if it jams! "

Li Qinwu was stunned by what Lao Huotou said. He didn't expect that the AK47, which was famous in later generations, would be devalued by Lao Huotou.

This is actually Li Qinwu Menglang's fault. At that time, there was no ammunition specially produced for automatic rifles. They were either pistol bullets or full-power rifle bullets. Therefore, the AK47 had no room for survival.

And just as Lao Huotou said, it is too costly to make such a weapon. The strength of parts and magazines are not up to standard. It will definitely not be as brilliant as the gun kings of later generations.

Li Qinwu could only put the blueprint back into his pocket silently. Although the old man said it was worthless, he still decided to study it carefully in the future to see if he could modify it.

AK47 is the version answer. If someone knows the answer but doesn't go for it, then there must be something wrong with his brain.

Seeing Li Qinwu's frustrated expression, the old man smiled and planned to encourage the young man.

"Young man, don't be too fanciful, we need to be down-to-earth.

Although this strange gun you made may not be put into practical use, your ability to design guns is still very impressive. You can design some submachine guns and rifles based on our current conditions. If you can do it, maybe they will be adopted by the factory?"

Li Qinwu raised his eyebrows and felt a little nervous.

"Old Firehead, if I can design a submachine gun with better performance and it is adopted by the factory, will you give me a reward?"

Old Huotou was amused. This kid was really trying to climb up the ladder. Did he really think he could make a gun?

But the young man still needed encouragement, and he patted Li Qinwu's shoulder with his calloused hands.

"Of course, kid, if you can really make a useful weapon, the young marshal's reward will be enough for you to live on for the rest of your life.

Let me tell you, half a year ago I made a small part that can increase the efficiency of the bullet production line by 5%. Do you know how much money the Marshal gave me? 5 yuan! A full 5 yuan! "

"hiss!"

Li Qinwu took a deep breath and looked up and down at the old man's skinny body. The old guy is so rich! Um... it doesn't seem wrong to kowtow to him, right?

Shaking his head, Li Qinwu said goodbye to Lao Huotou and walked towards the factory workshop. Today was a very fruitful day. Not only did he practice shooting, he also stole 10 bullets and developed a way to make money.

If he wants to make more clones, he will need more money. Lao Huotou was rewarded 50,000 oceans just for designing a small part. If he makes a gun that can be of great use, shouldn’t he be rewarded 100,000 or 200,000 oceans?

Li Qinwu returned to the workshop. It was about 6 o'clock and time to get off work. There were still two workers working at the lathe in the workshop. These two workers had just arrived in the workshop not long ago and were not familiar with the operation of the lathe. They worked very slowly and often had to work overtime.

Li Qinwu came to his workstation and disassembled the machine tool pretending to perform maintenance. After about 10 minutes, the two workers finally completed the final workpiece.

One of the workers saw Li Qinwu dismantling the machine tool and greeted him, "Master Li is really hardworking. He is still maintaining the machine after get off work. Otherwise, Master Li's skills are good. We should learn from Master Li!"

Li Qinwu smiled back.

"This machine is the livelihood of our workers. We must maintain it regularly. Otherwise, if something goes wrong during work, it will delay things."

The two said yes, and after a brief greeting, they left the factory. After Li Qinwu made sure that the footsteps had gone far away, he simply closed the door of the workshop and took out various parts from his pocket.

These parts include triggers, firing pins, bolts, springs, and metal parts. Although they are all scrap parts that need to be recycled, Li Qinwu will give them new life.

Turning on the machine tool, Li Qinwu picked out several parts needed for processing, and welded the various parts together with a welding gun.

Since he already had the design in his mind, he completed the tasks in less than 10 minutes.

This is a gun that looks like it's made of water pipes and garbage. It is 30 cm long and can only fire one bullet at a time. After firing, you need to manually pull the bolt, use your fingernails to pick out the shell, and then reload it before you can fire again.

But this is not the end yet. Fengtian City is the capital of the north. Once the gunshots are heard, the armed forces of the entire Fengtian City will be mobilized. Li Qinwu does not want to risk his life for revenge. Fortunately, he has a solution already.

He picked up an oiler specially used for oiling lathes. It was thicker than a mineral water bottle and made of metal.

The lubricating oil inside had been cleaned long ago. He unscrewed the oil filling port and placed the cylindrical pot body on the lathe for processing. He wanted to rub the muffler by hand.

The principle of the silencer is very simple. A bunch of soundproof chambers are built in the cylinder. After the gun is fired, the gunpowder gas will collide and cancel each other out in the soundproof chamber to achieve a sound-absorbing effect.

The thicker and longer the silencer, the larger and more numerous the soundproof cabins, and the better the sound-absorbing effect. The size of this oil can is sufficient.

Li Qinwu began to process the metal sheets and weld them to the inside of the oil can, and the soundproof cabin was completed.

Next, he used a discarded gun muzzle to make a screw-on joint and welded it to the muzzle and silencer so that the two items could be combined.

This hand-rubbed silencer is very rough, and the welds are very disturbing. I always feel that the silencer will explode after a few shots. Even with a silencer, the sound when the gun is fired is still very loud, so modifications must be made to the bullets.

Li Qinwu took out three bullets that he had just stolen during target practice, clamped them on the machine tool, removed the bullets with pliers, poured out the propellant in the cartridge case, filled the gap with cotton, and reset the bullets.

He is going to use reduced-charge bullets. The silencer and reduced-charge bullets should be able to eliminate the noise caused by shooting to a large extent.

Li Qinwu made three reduced-charge bullets, reducing the propellant by 25%, 50% and 75% respectively. He will need to test which simplified propellant formula makes the least noise and has the best lethality level.

After doing all this, Li Qinwu stopped the machine and cleaned up all the mechanical debris, found the oil paper from the warehouse, picked up the gun and silencer, hid them under his clothes, and walked out the door.
