"Not Stern? What is that?"
"We don't have a unified code name either. Let's just call it M3."
"Ai Mu San Gai? What the hell?"
Brigadier Wang continued to be confused.
As Old Chen said, your brain is not enough when you come to the arsenal.
It has a modified word, it should be an improved model of some kind of gun.
But after so many years of fighting, I have never heard of a gun called M3.
"I have to ask Comrade Zhu Han about this. I don't know what he is capable of, but he can just get the blueprints of the firearms that Dai Ying and the United States are testing."
Hearing such slightly yin-yang words, Zhu Han shrugged and said he didn't care at all.
What he showed Zhao Sizhe was even the drawing of the Sten mk5, which was designed only 44 years later.
It is already a much improved model.
But it still opened his eyes.
What a crappy gun.
"I have my own methods."
With that said, Li Dayou brought a self-produced submachine gun.
If there are any military fans present, they will immediately say, isn’t this an M3 Type II?
But look closer and you'll notice something is wrong.
Because this thing is based on the M3-mk2 submachine gun and combines the characteristics of the McDawson submachine gun.
If we talk about the American grease gun, it is naturally a household name.
But when it comes to McDawson, fewer people know about it.
This is a submachine gun made in Denmark during the Cold War.
The biggest feature is that the entire gun body is made of two stamped steel plates.
There are two sleeves welded on the butt of the gun and the bottom of the grip, which are connected by nuts and nuts like the hinges of the door panel.
The front is fixed by a nut.
Compared with the M3 gun body that is welded together and cannot be taken apart at all.
Once the nut holding the barrel of the McDawson submachine gun is removed, the gun can be opened like a book.
It can be said that they are completely two extremes.
"Since we already have a mature M3, why do we have to make such a big change over the short distance?"
Brigadier Wang began to understand Zhao Sizhe before.
Zhu Han expressed his frustration:
"There is nothing we can do. The industrial base of the United States is not comparable to ours."
"For example, take this barrel-fixing nut. The M3's nut requires very high thread processing levels. It must be screwed to a certain position and it will fit tightly. It cannot be tightened too much or too little. For this reason, they also specially designed the threads on the gun body and The corresponding positions of the nuts are marked.”
"Moreover, the barrel and bolt are both cylindrical. In order to prevent the barrel from rotating with the bullet, a metal piece must be fixed at the back of the nut, which is too troublesome."
Originally, the United States had its own submachine gun, the famous Thompson.
But this thing is too expensive, more expensive than a Czech one.
There was no other way, so I used the idea of the Sten submachine gun to come up with something that looks like an oiler.
It seems simple, but the details are still quite troublesome.
Just to prevent the bolt from turning back and forth, two recoil springs and recoil guide rods are used.
And whether it is the bolt opening or the recoil spring, it must be made larger at one end and smaller at the other.
Zhu Han would never accept this alone.
Just do what McDawson did, open a guide groove on both sides of the bolt, and leave two guide rods when stamping the receivers on both sides, saving labor and materials.
It is said that punching, riveting and welding are the three magic weapons to reduce costs, but the prerequisite is that they must be available.
The M3 submachine gun is simple to make because it uses a lot of welding technology.
Since the United States entered the war, factories manufacturing automobiles, building materials, and furniture, as long as they can perform metal processing, have all invested in it.
The power plant and welding machines are all ready-made.
Anyway, affected by the economic recession, these factories are just one breath away from death. Why not work hard if there are orders?
However, the current power of the Eighth Router cannot satisfy so many arc welders working at the same time, so we can only find other ways.
Therefore, if the M3 gun was made by another country, it would never be possible to achieve the low cost of the United States - although it is not very cheap.
"Then since the tail of the barrel has been processed into a square shape, why not make the entire gun into a square shape? This will save the need for a guide groove."
"I also asked this question at the beginning." Zhao Sizhe answered directly for Zhu Han, "When crawling forward, do you feel more comfortable holding a cylinder or a square pillar?"
"Cylinder."
"Then do you think it's easier to punch a curved surface or a right angle?"
Brigadier Wang thought for a moment and said, "It should be a curved surface."
"Finally, the receiver is the place that bears the greatest pressure. If the cut surface is a circle, it can bear the pressure evenly. If it is square, the point on the corner that bears the greatest pressure is the point on the corner."
"The opposite is also true. The round ones are the least likely to be damaged by external collisions. They don't use very good steel, but they also ensure strength. It kills two birds with one stone."
Zhu Han shook his head and sighed:
"It can be said that this was done out of sheer desperation."
"In order to reduce the difficulty, I even canceled the loading handle on the original M3, leaving only two small holes on the front and rear of the bolt."
Well, this is not his credit, it was canceled by the mk2 type himself.
But Zhu Han doesn't have any psychological burden at all when he takes credit from Americans.
"Because this submachine gun is open and ready to fire, two craters can be exposed when the bullet is not loaded."
"If the bullet is loaded, only a pit will be exposed. With the two small buttons protruding from the dust cover, it becomes a simplified version of insurance."
"The disadvantage of this is that if you want to load the gun, you have to rely on the soldier to put his finger into the hole and pull the gun back."
"The advantage is that whether it is kept in peacetime or needs to be temporarily protected during war, as long as the dust cover is closed, the small button can lock the bolt, ensuring that it will not misfire, which can greatly reduce training costs."
Brigadier Wang also saw some of it and quickly asked the question he was most concerned about:
"Then what's the cost of our submachine gun?"
"About 20 dollars."
"That's it..."
This answer was somewhat unexpected by Brigadier Wang.
After all, in his opinion, as long as Zhu Han does it himself, it will definitely show the magical power of Zhu's algorithm.
"It's almost twice as expensive as Sten..."
As a result, before he could finish his words, he was interrupted by two people in unison:
"No! Want! Si! Den!"
Zhao Sizhe continued:
"Do you think we haven't made a prototype gun? Not to mention anything else, just the magazine on the left side is extremely counter-intuitive."
"Ah? Left-hand magazine? Isn't that what the flower mechanism is like?" Brigadier Wang scratched his head again.
Zhu Han: "But have you ever seen a submachine gun whose magazine well moves with the magazine?"
Si Zhe: "The magazine well of the Sten still wobbles back and forth no matter how tightly it is loaded."
Zhu Han: "The gun itself is short, and with such a big magazine placed there, people subconsciously use the magazine as a grip."
Sizhe: "But that will make the magazine shake more and make it easier to jam!"
Zhu Han: "Soldiers have to be trained to either grasp the heat dissipation cover of the barrel in front or the gun body in front of the trigger guard. Who can think of this when the battle is fierce?"
Sizhe: "And even if you operate it as required, it's still very easy to get stuck!"
Zhu Han: "Pull the charging handle vertically a little to disengage the insurance, and press it down to disengage the insurance. It is not obvious and cannot be seen at all in an emergency."
Si Zhe: "And its insurance is particularly insecure and it is very easy to misfire. So..."
The two of them shouted in unison: "Trash Stern! You don't even need a dog!"
The two senior intellectuals sang in harmony like a pair of comedians.
"In short, we can't bear to let the soldiers go to the battlefield with a piece of iron pipe garbage to fight for their lives!"
Seeing the two people in front of him whose defense was broken because of his unintentional words, Brigadier Wang could only be deeply moved.
They did this because they really cared about the lives of their soldiers.
No matter how bad the Sten is, as long as it can be made, it will definitely be a good gun for the Eighth Route Army who are short of guns and ammunition.
Isn't it much easier to use than a single pout?
But these two.
If you were abroad or a bald person, you should not be able to enjoy all the glory and wealth.
Now, for our soldiers, we are desperately looking for a balance between firearm performance and cost.
Even though the submachine gun is small, it seems extremely crude.
In fact, every detail inside reveals the designer's concern for the soldiers.
The most critical thing.
All the parts in this gun are indeed made of materials that can be produced today, and are even said to be common in factories.
The structure is simple and the materials are simple, but the performance is not bad.
You know, it is already difficult to find answers to complex questions.
And being able to perfectly answer complex questions with extremely simple answers only shows that the level of the problem solver is completely overwhelming.
We, the Eighth Route Army, are so lucky!
Old Chen! Lao Chen!
I got you!
