Just after the beginning of winter, the development of a new automatic rifle, which lasted nearly a year, achieved phased results -- the trial production of the sample gun was successful, and then it was put into the intense live-fire test stage; just as the so-called mules are horses drawn out for walking, and the same is true for firearms; no matter how advanced the data on paper is, only a few real hits can see the real advantages and disadvantages.

The new automatic rifle naturally cannot jump out of this universal truth, and because of this, this trial really found a lot of problems, such as the front sight base is not firm, and then the muzzle jumps too much during continuous firing, and there is a serious cause the firing pin in the gun to break, and so on.

So from mid-November 1949 to the beginning of March of the following year, the automatic firearms research team led by Bai Yi went back and forth between the shooting range and the workshop, while finding the cause of the failure, while starting to improve, and at the same time conducting tests, the reason why the test was so long was to make a comprehensive evaluation of the performance of the firearm, and on the other hand, to test its reliability.

However, aside from these positive reporting reasons, the most important thing is that Bai Yi and others lack the necessary testing equipment, unlike the firearms inspection and testing in the previous life, there is a professional venue, surrounded by high-speed cameras, stress rangefinders, speed measuring instruments, and even temperature control equipment.

As for high-performance computers, professional target positions are indispensable, and it is with the support of such powerful professional equipment that firearms designers can see at a glance the data such as pulling the trigger, bullet ejection, flight trajectory, hitting the target, and damage effect as long as they sit in front of the electronic display screen behind the scenes.

What is the problem in that place, and there is an abnormal fluctuation in that position, all of which are supported by computer calculation data, as long as the comparison data can quickly find the cause of the error, but now, there is no high-speed camera, no professional measurement equipment, and no measurement equipment for calculation.

If you want to get the basic performance data of firearms, you can only use the simplest password, stopwatch, tape measure, hands and eyes, and the data deviation can be imagined, so whenever he dreams back at midnight, Bai Yi is very envious of the previous equipment inspection work, as long as he sits in front of the computer and crackles and enters a few sets of data, he can know all the situation.

But now, the most advanced computing equipment is the abacus, and the fastest measuring tool is the pointer on the stopwatch, all of which need to be calculated manually, and then compared and found the cause of the error in the same way, if this work is done for a week or two, if it is done repeatedly for more than three months, it will simply drive people crazy.

However, the people of the automatic firearms team are a group of people who can endure loneliness, not how noble their consciousness is, let alone for any gain or loss, what they want is to do a good job of this gun that belongs to the Chinese themselves, to do it well, to be refined, and to be simple, but it reflects the conscientious deeds.

Bai Yi was very uncomfortable at first, and even prepared to set up another stall to engage in computers, but there was no time to talk about it, but in terms of materials and equipment, they were two powerful obstacles, but just when Bai Yi was worried about testing, Chen Yaoyang, Wang Dehua and many colleagues who developed new guns with him used a simple and pure approach to move Bai Yi.

This is the loveliest thing about the Chinese military workers, they do not ask for rewards, they do not talk about reports, they use their own hands without equipment, even if it is difficult, they will have a bright smile, even if they are frustrated and hinder the progress, they are not complaining, let alone waiting, but using everything that can be used to solve the problem in front of them.

Maybe history can't remember the names of each of them, but the military industry spirit they created together has been passed down from generation to generation, Bai Yi, a graduate student of military equipment who is used to using computers and checking equipment, naturally has this spirit in his body, but he has not discovered it or started it.

Now looking at the colleagues who have worked tirelessly and silently, he finally knows that with them, China's backbone will one day stand up, so he put aside his unrealistic ideas, picked up the pen, held the straw paper, and threw himself into these colleagues, recording with a pen and measuring with a ruler, so that he finally improved the new automatic rifle step by step to such an extent.

"Well, Lao Bai, I know that you have a very high demand, in fact, to be honest, this gun is already very good, just say that a few days ago, I also took it to the deputy commander of the military subdivision Qin to hit a few times, he liked it very much, and kept asking if he could give priority to equipping the troops under his command, not to mention that this gun has been fired for more than a month, nearly 100 rounds of bullets every day, even the iron pestle has been sharpened into a needle, and it is normal for the gun chamber to be a little worn!"

How did Lao Ge know that Bai Yi was infinitely emotional, and he only thought that frowning was dissatisfied with the problem of the barrel, and he comforted him with words, but as soon as he finished speaking, Chen Yaoyang, who was in charge of recording the shooting situation, shook his head seriously: "Our design life is more than 3,000 rounds of barrels, but now, the rifling in the barrel of more than 1,000 rounds is worn and burned."

If that's the only thing to say, the key is the gas conduction piston of the firearm, because of the continuous erosion of ignition, there has been serious metal fatigue, usually it's okay, if it's on the battlefield, the damage to the air duct is tantamount to the scrapping of the whole gun, and the loss at that time is not a gun, it may be the life of our soldiers! ”

"This ......" Hearing Chen Yaoyang say this, he couldn't just say what was good, he could only look at Bai Yi, and at this time, Bai Yi was also pulled back to reality from his thoughts by the argument between the two, so he nodded: "Yes, the problem of the barrel and the air duct does need to be solved!" ”

"That's true, why don't we try another type of steel? Maybe you can find a material with good reliability? Chen Yaoyang thought for a while and then suggested, but Bai Yi shook his head: "We have tried four or five kinds of steel, but the effect is still not ideal, so I think our plan for improving the barrel has deviated from the beginning, and now this batch is a special barrel steel for the Soviet Union, and the effect is still the same, so we have to think of other ways!" ”

"What better way to do this than to solve the root of the material?"

"Of course there is!"

"What's the solution?"

"For example, chrome plating on the barrel!" Bai Yi wrinkled his brows and finally let go, revealing a bright smile......
