Chapter 42, Firepower Coverage is Necessary
That is because after the Type 63 automatic rifle went into mass production in 1969, in order to simplify the production process, reduce production costs and improve production efficiency, the receiver that was originally directly cast, forged and milled was changed to a stamped and riveted receiver, and the threaded connection between the barrel and the receiver was also changed to a cylindrical hole press fit connection.

The problem is simple, but the solution is difficult.

Wang Duoyu did not say much about the production problems of the 626 Factory and the technical problems of the Type 63 automatic rifle. His purpose of coming here was simple, to trial-produce the improved Type 78 automatic rifle as soon as possible.

However, Ge Jianshe also reminded him yesterday that we don’t have 5.56*45mm bullets here, so it would be useless even if he tried to produce that type of gun. But it doesn’t matter, he still has another gun with a caliber of 7.62*39mm.

"Hello, technician. It has been produced. Please test it."

The workers helped produce the receiver. After Wang Duoyu took it, he asked him to use a vernier caliper to measure it. The result was more than five inches off, and his face instantly turned dark.

"Director Hao, does your factory have any skilled workers? The width of this receiver is 5 inches shorter than expected. This skill is too poor to meet the standard."

Hearing Wang Duoyu's words, the worker's smile froze instantly. Before Hao Guoliang could speak, the worker had already started to defend himself:

"It's just a small difference of 5 wires. Although it is a little smaller than the drawing requires, if it is too wide, there will be a gap during assembly, so the opening is smaller and it can be assembled with a little prying."

Upon hearing this, the workshop director quickly nodded in agreement, "Yes, this has all been agreed upon by Team Leader Ge and the others, and Director Hao and the others are also aware of it."

Good guy, he actually dragged the leader into the water in front of the leader and others. This workshop director is so stupid. Does he have negative EQ?
If the door was closed, Hao Guoliang, Ge Jianshe and others would certainly not mind what the workshop director said, but now there are two outsiders, Lin Dehong and Wang Duoyu, present. How could such an idiot say such a thing?

Is your brain really stuck in the door?
Hao Guoliang and the others' faces were extremely dark. Lin Dehong shook his head with a mocking look on his face and said nothing. However, Wang Duoyu was amused and asked, "What if they pry too much?"

"If you've pried too much, just knock a little more and go back. I'm saying, young comrade, why do you have so many questions? Do you understand production at all? If you don't understand, don't give orders blindly. Let Team Leader Ge and the others do it."

The workers seemed not to notice the expressions of Hao Guoliang and the others, and they had lost their patience with Wang Duoyu.

"Then do you know how strong manganese steel is? If it's fixed after assembly and can't be reset, are you responsible? If it's too heavy, it will affect the barrel and other parts inside. You, a worker in the production workshop, don't understand this, so don't the workshop director and technicians understand it? No wonder the Type 63 automatic rifle was temporarily withdrawn, haha."

After retorting to the worker, Wang Duoyu didn't look at him again, but turned to look at Hao Guoliang and said:
"Director Hao, if your factory really doesn't have suitable skilled workers, or if your skilled workers have such an attitude, then forget it. I'll find a solution later."

The M4A1 carbine is a very standard standard weapon, not only because Sam's technical workers are awesome, but also because they have a lot of money and good equipment, so the firearms and equipment they produce are of course very powerful.

Although the US military had very advanced weapons and equipment on the Korean Peninsula battlefield, we still defeated them. But it is undeniable that their weapons were indeed very powerful. On the other hand, our country was helpless. We had backward equipment, less skilled workers, and different concepts, so it was normal that the situation was bad.

Why were the production processes of the Type 63 automatic rifle required to be simplified? It was because they had no money and were too poor. The design had already been completed in 1963, but large-scale production only began in 1969, with a gap of six years in between, all because of poverty.

Therefore, things that are engraved in the bones cannot be changed all at once.

The atmosphere was a bit awkward. Lin Dehong knew that there must be some secrets in the factory that were unknown to outsiders. Moreover, he himself did not understand the technology, so every time he came to the 626 factory, he was actually fooled. Now that Wang Duoyu understood it, he finally understood.

"Director Hao, I didn't understand before, so no matter what you said, we didn't care. But now that Comrade Xiao Wang has made the interests clear, I hope you can tell me honestly whether this firearm can be successfully produced."

For Lin Dehong, he only cares about whether the soldiers under his command can get the best weapons, because if not, then the soldiers can only carry out tactical penetration. But now it is obvious that the weapons and equipment provided by Wang Duoyu can provide fire coverage, so of course he hopes for fire coverage rather than tactical penetration.

In addition, his attitude towards life is different from Ge Jianshe's, who is all about lying down and doing nothing. He is only 43 years old this year, and perhaps he is already an old man in the army, but if he can go one step further, then the scenery and heights he can see in his life will be even more different.

"Staff Officer Lin, don't worry, this firearm can definitely be produced. I guarantee it."

Facing Lin Dehong, whose anger was about to erupt like a volcano, Hao Guoliang got goosebumps all over his body. He quickly responded in a serious tone, then looked at the workshop director and others and roared.

A few minutes later, several senior technicians and eighth-level workers gathered and worked hard to assist Wang Duoyu in producing the gun parts he needed.

Since the materials have not been produced, the receivers and other parts that Wang Duoyu can get now are definitely not in the best and most perfect condition. For example, the barrel is still made of manganese steel, not the high-alloy chromium-molybdenum steel he wants.

The barrel of the M4 carbine is made of high-alloy chromium-molybdenum steel. The advantages of this barrel are durability, high strength and uniform wear. Because this type of gun requires long-term continuous shooting, the requirements for the barrel are of course very high.

High-alloy chromium-molybdenum steel barrels have a long lifespan and can withstand high pressure and high temperature. They are suitable for automatic weapons or high-rate-of-fire weapons and can perform stably during continuous shooting.

In addition to high-alloy chromium-molybdenum steel, stainless steel is also acceptable, but stainless steel was only used after the 1980s. The current five or six family buckets use chromium-nickel alloy steel and high-strength steel.

Two days later, all parts including the barrel had been produced and testing was imminent.
