"Xiao Xie, are you moving?" For Xie Kai to enter the office of the gun repair workshop with a thick stack of books, Han Weidong and the others who were busy were very surprised.

Xie Kai grinned, "I'll supervise the work." ”

Han Weidong and the others didn't care about his supervision, and the internal guards of the base were stricter than other places in guarding this workshop.

"You feel free. If you don't understand something, you can ask them, there are a lot of people in this gang who are quite boring. Xiao Manzhi pointed to the busy group of thirty or forty technicians in the technical room.

Xie Kai nodded hurriedly.

He is hiding here just to hide from Chen Yixin.

The woman didn't seem to care about other people's gossip at all, if it weren't for the fact that she was just using the base as a springboard, Xie Kai wouldn't have found this woman terrifying.

Even Li Li, whose family background is far higher than Chen Yixin, has not accepted Qian Fatzi now, even if she is using the perfume and skin care products given to her by Qian Fatzi, she has not heard of any outrageous behavior with Fatty.

However, Chen Yixin, this woman, Xie Kai thinks, it is best to hide as far as you can.

Perhaps she is also ready to use herself as a springboard.

The attitude of the base management committee towards herself, it is impossible for her mother Zhou Rong not to know.

The modified sniper rifle is progressing very quickly, and since it is based on the three 79 snipers that have already been equipped with the troops, it is not necessary to produce all the parts, and now it is only an experimental product, as long as it can meet the design requirements, there is no problem.

On the third day, various design improvement drawings came out.

Xie Kai was here, coordinating with Wang Guilin, and the supply of various materials in the base was prepared very quickly, and the various equipment of the production line of the firearms workshop, which had not been started for a long time, began to operate.

Even the lenses of the scope are handmade by the people inside.

Xie Kai had his first close contact with the processing of various parts of firearms.

Of course, this is only the production of firearms in the conditions of artisanal production.

Almost all of his food and accommodation are in this workshop, like other workshops, there is a rest room for tired technicians to rest and even sleep, a bathing room, and a shared canteen with the next research unit, but the daily meals of the people here are called from the canteen by special people.

Xie Kai was not averse to this situation, and took some time out every day to study the things in the textbooks, and also began to read various gun theories and previous design manuscripts in the test workshop, and his theoretical level in the field of firearms improved rapidly.

Xiao Manzhi, Han Weidong and the others did not express any opinion on his existence, as long as Xie Kai did not affect their work.

Xie Kai is here, their various treatments have been significantly improved, and even if they want various materials, they can be supplied in a very timely manner.

Therefore, they are even more grateful for Kai's existence.

"This is the beginning of the assembly?" I don't know if a few days later, Xie Kai is here, and he has no concept of time at all.

The people in this group also have no concept of time when they work, they sleep in the lounge when they are tired, someone brings food when they are hungry, and when they are bored, they can brag and talk nonsense to these technicians, or learn from them the stories of many old guns from the World War II era on the walls around them.

After contact, Xie Kai found that these people were no different.

Many people regret what they did back then, otherwise, they would not have accepted such an arrangement from the base.

In such a mentality, they are naturally not lazy or anything when they work.

Moreover, this is the only chance to change their current situation.

Xie Kai didn't know how long he hadn't left this workshop, anyway, everyone here was like this, when one day, when he was bored, he asked in surprise when he watched Xiao Manzhi reassemble the disassembled 79 sniper with his own hands, and the scope on the gun was much thicker than the 4 times white light sight originally used.

"yes, it's been more than ten days. Xiao Manzhi looked focused, there were a bunch of neatly arranged parts and tools on the workbench in front of him, and he didn't have time to pay attention to Xie Kai, and Liu Wen, an apprentice next to him who was already familiar with Xie Kai, whispered.

"How accurate is the assembly?" Xie Kai asked.

The accuracy of the assembly of a top-of-the-line sniper rifle is simply unimaginable for outsiders.

Otherwise, Liu Wen, a 36-year-old gunsmith, would not have given up his job.

"I don't know, my master's assembly must be much more accurate than mine's. "There is no theoretical assembly data, only the highest accuracy they can achieve," and the tightness of each screw even affects the accuracy of the gun. At present, our experiment is to solve the problem of the accuracy of the gun first, and then solve the problem of service life. ”

Xie Kai knows this.

The two exchanged words in a whisper while looking at Xiao Manzhi, who looked focused.

Xiao Manzhi's actions made the word level nine flash in Xie Kai's mind.

This kind of demeanor, as well as the assembly where each action of the screw is consistent with the frequency, and there is almost no difference in the strength, Xie Kai only appeared on Wei Lao and other ninth-level fitters.

A firearms designer and a top-notch fitter, how accurate is the sniper rifle made in this way?

The 79 sniper rifle is different from the 81 automatic rifle, there are a lot more parts, and after this modification design, the parts of the gun have been increased.

For the sake of higher accuracy, especially long-range shooting accuracy, versatility is not considered at all, the only thing that is considered is accuracy.

A top-of-the-line sniper rifle, the cost is certainly top-notch.

Then, the problem of improving the accuracy of batch parts is studied in reverse.

From Xie Kai looking at the assembly to finally seeing the finished product of the gun, it took Xiao Manzhi almost three hours in total!

Even the scope was assembled by him.

During the entire assembly process, Xiao Manzhi did not have any other superfluous actions.

"Deputy Xiao, what's wrong?" Xie Kai asked Xiao Manzhi, seeing that he was a little tired and too focused, which brought such consequences, he hurriedly handed Xiao Manzhi a tea cup.

Xiao Manzhi took it and sighed, "The specific situation will only be known after the dynamic design." ”

"When is the experiment, what is the experimental standard?" Xie Kai asked with some urgency.

He wants to see a high-performance sniper rifle that can hit hundreds of meters with precision.

"The experiment depends on the base arrangement, as for the experimental standard, if it is the world's top sniper rifle, the assembly accuracy is within 0.01 mm, and the shooting accuracy is required to be within 100 yards, and three consecutive shots are required to hit an area no larger than the size of a one-yuan Great Wall coin. Xiao Manzhi said to Xie Kai, "This gun is just a modification, and it is impossible to achieve it." ”

"What about the accuracy range? Can it be controlled to shoot accurately within a range of several hundred meters?" Xie Kai also knew that it was a complete fool's dream to achieve the world's top level if he wanted to transform it like this.

"It depends on the data of the test. The effective range of the 79 sniper is 1,000 meters, but it is equipped with a 4x fixed magnification telescope, in this kind of scope, the image of a person of one thousand meters is not much larger than an ant......" Xiao Manzhi said with a wry smile at Xie Kai.

Xie Kai was a little shocked.

He hadn't seen the world inside the sniper scope, and he didn't know what the target in the scope looked like 1,000 meters away.

"Isn't it a legend that there are sharpshooters on the front line who have set a sniper record of 1,300 miles away?" Xie Kai didn't know when this legend took place.

Anyway, he didn't know that what was blown on the Internet was amazing.

Xiao Manzhi looked at him, smiled, and didn't say anything.

"In the scope, 1,000 meters of character imaging is only not much bigger than an ant, 1,300 meters, how big do you think the target in the sniper scope is? And outside the effective range of 1,000 meters, according to the density of the air, the size of the wind, etc., the trajectory of the bullet has long been unknown. The heavy warhead of the 53 machine gun cartridge itself is not precision-made...... "Liu Wen explained next to him.

Xie Kai was a little embarrassed.

"Isn't the scope of our gun newly designed, can it reach 9 times?" Xie Kai changed the topic to avoid the embarrassment caused by his ignorance.

"The design accuracy of the gun itself is not high. Even the Soviet Dragunov semi-automatic sniper rifle, equipped with professional sniper bullets, has a dispersion range of half a chest width and more than 20 centimeters! Even with a scope with a higher multiplier, no one can guarantee how high the accuracy will be without professional sniper bullets and without a large number of live ammunition training. Xiao Manzhi said.

No matter how good a weapon is, it depends on who is in it.

In the era of the Red Army and the People's Liberation Army, there were no snipers in China, and there are no snipers now, but there are countless sharpshooters with accurate marksmanship.

They don't have any sniper scopes.

"So, we can only test, and what we can do is to continuously improve our manufacturing accuracy. Sometimes with a bit of luck, even if you are out of range, you can take out the target! On the battlefield, anything can happen. Xiao Manzhi said.

Liu Wen also nodded, "Only some of the parts of our gun are made by us this time, and the accuracy that can be improved is limited." What can really see the improved design of this time will have to wait until the day after tomorrow, when we assemble a new gun with various high-precision parts of our new production. ”

"The accuracy of the previous parts was not high?" Xie Kai thought incredible.

79 is a sniper rifle!

The production of sniper rifles is much more demanding than ordinary automatic rifles.

"Mass-produced things, and from the design to the equipment of the troops, there is not much time at all, how high can it be?" Liu Wen said. "In the manufacturing process, in order to solve the problem of combining guns and mirrors, the Soviets relied on their superb craftsmanship to solve it, and the tolerances were controlled within a very small range. Our domestic manufacturing capacity would not have been able to reach the level of the USSR in the first place......"

Xie Kai finally knew how the Soviets' sniper rifles solved the problem of loose sight rails and gun bodies due to too large gaps in the position of the bamboo shoots.

Now I really know how a good sniper rifle with high precision is made.

Xie Kai nodded, "I'll go to Lao Wang and ask when the dynamic test will start." ”

Xiao Manzhi did not stop it.

After drinking water, he continued to devote himself to the assembly of another gun.

"How much can the accuracy be improved?" Wang Guilin asked Xie Kai on the phone when he knew that the gun was assembled.
