Looking at Chen Yaoyang and Wang Dehua, Bai Yi stretched out three fingers, put down one and said: "Over the past few days, I have repeatedly emphasized that the fully automatic rifle we have developed this time must be mature, durable, and suitable for the current stage of industrial production capacity." Pen % fun % Pavilion www.biquge.info

The so-called maturity is not only that we must be familiar with it, the relevant craftsmanship must be mature, but more importantly, the commanders and fighters of the army must also be easy to use. As for the second point of durability, it is also very important, any situation can happen on the complex battlefield, so our guns must ensure that they can fight in harsh environments.

However, compared with the first two points, I value the third one more, if the current stage of the industrial capacity can not bear the design, even if our idea is good, the so-called automatic rifle will inevitably stay on the drawing, so at this point I think is the direction of our key thinking.

Since that's the case, it's simple, everyone just need to refer to the production capacity of our Baiyun factory to see what kind of gun we can produce, let's start with the bolt first......"

As he spoke, Bai Yi took the M1 carbine, Thomson submachine gun, and the Japanese Type 4 semi-automatic rifle captured from the bandits, and unloaded the bolts of the three guns after dividing them by two, and immediately put them in his hands, facing the people present: "These three guns with obvious American blood are the most common continuous firing weapons we can find in the realization stage, and their bolts are all rotary locking bolts without exception.

This bolt is compact, lightweight, good locking performance, and has been applied in many firearms, to be honest, this bolt is the best choice for automatic firearms, but because of this, our problem is also coming, such a good bolt is produced smoothly and efficiently at our current machining level? ”

Bai Yi's eyes looked at Wang Dehua in front of him, Wang Dehua stared at the three bolts, the swarthy bamboo shoots, opened his mouth, as if he wanted to say something, but in the end he closed it helplessly.

On the other side, Chen Yaoyang showed a hint of imperceptible smugness when Bai Yi spoke, and then nodded and took over Bai Yi's words: "Chief Bai is right, this kind of rotary locking bolt is good, but it requires a lot of machining and cutting technology, especially the raised bamboo shoots on the head of the bolt, which requires very high precision, and a slight deviation may lead to the failure of the firearm to open and close the lock normally, and then make the firearm unable to be used normally. ”

"That's right, on this kind of bolt, I have done it myself a few times, not to mention the amount of cutting, the scrap rate is also very high, the waste of raw materials is also very large, and more importantly, because our heat treatment is not good, so that even if we successfully produce this kind of bolt, we can't beat the original foreign orders, all in all, it is not cost-effective!"

Although Ren Xudong is a little hesitant in dealing with the world, he is a straight intestine, he has one thing to say, some to say two, and never hides it, but his words are like a thunderbolt that resists the future, and the last bit of hope in Wang Dehua's heart is completely destroyed.

You must know that although Wang Dehua and others insist on building China's own fully automatic rifle, they do not say that they will not use a mature firearm structure, and among them, what they can come into contact with is also the most widely used, that is, the current rotary locking bolt structure, because in their imagination, the automatic firearm that is about to carry out the initial design should also use this bolt.

But he didn't expect that his idea was still brewing in his head, and it was completely denied by the ruthless reality, the processing is difficult, the scrap rate is high, the waste of materials is serious, and the service life is short.

You must know that in many military factories, including Baiyun Factory, there are not many skilled workers like Ren Xudong, and the machining accuracy of the machine tool is not very ideal; The resulting scrap rate and waste of raw materials are inevitable.

If it is a developed country with a strong foundation, it is okay, even if it is wasteful, it can be replenished, but the question is what kind of foundation does China have at this time? Even a piece of straw paper has to be cherished incomparably, the raw materials used for firearms manufacturing can be imagined, and because of this, the above four can be said to be a "big taboo", even if the firearm is made, the superior will not carry out large-scale installation, because the only little bit of family money is really unaffordable.

"So my suggestion is right, the mature firearm has been modified at this stage, retaining its bolt assembly, adjusting the firing composition, strictly controlling the ammunition load, and implementing matching, for which I think the improved M1 carbine we have carried out before is very good, what is lacking is reliability, so we can continue to work hard in this regard."

Seeing Bai Yi's words, Wang Dehua and others shut up, Chen Yaoyang stood up and said his opinion, in his opinion, the improved M1 carbine is very good, but at that time, in order to catch up with the schedule, only the problem was solved, and the existing defects can be slowly changed, not to mention that the improved M1 carbine fully meets Bai Yi's requirements:

Its bolt and gas guide device are almost immovable, and this alone greatly simplifies the production process, as for the barrel, it is a difficult point for the research group to tackle key problems, and for the troops, the M1 carbine will not be unfamiliar with the improved M1 carbine, because the two have strong versatility, because of this, Chen Yaoyang feels that the improved M1 carbine is the most in line with the current actual situation automatic firearm.

However, just as Chen Yaoyang was waiting for Bai Yi to give him affirmation, Bai Yi shook his head without hesitation: "Yaoyang, your method is good, but in this way, there are many manufacturing links missing, which will cause our developers and workers to be unable to systematically understand the manufacturing process of each component;

That is to say, the bolt components are saved, but our hands will also become lazy, if one day the bolt components of the guns in the hands of the soldiers are damaged or aging, just to re-open the bolt components processing production line, neither cost nor efficiency is cost-effective! ”

"This ......"

In fact, Chen Yaoyang has a whole set of theories about the pros and cons of the improved M1 carbine, but he didn't expect it, especially in the manufacturing and performance at this stage, after all, he has been thinking about this plan for a long time, but what he never expected is that Bai Yi's focus is not on the present, but in the future, not for processing technology issues, but on costs and savings.

And this was a problem that Chen Yaoyang neglected, so that he was still speechless after thinking about it for a long time......
