The next day, Lin Mo deliberately got up early, wanting to finish the things he left last night. To his surprise, it was not too late. Xu Guyu, Liu Zhenshan, and Zheng Junshan also got up early.
Not to mention Liao Tinghui and others, who had already gotten up for early training before dawn. Lin Mo and others had washed up, had finished training, and had gathered back to have breakfast.
Lin Mo and others had breakfast together, and Wang Shoufei took Li Laigeng to report to Zheng Junshan, inquire about the general mission, received a batch of relevant equipment, and left first.
The remaining Lin Mo and the others went to the equipment testing site with Liao Tinghui. The main part was a large factory building in the corner, plus a shooting range nearby.
This place is specially used to test newly developed equipment for Wu Liangdong. All kinds of newly designed and produced things will be stored directly in the large factory after testing.
Liao Tinghui asked someone to open the storage room. As soon as Lin Mo came in, he saw a long wall densely packed with various equipment, including firearms and gun accessories, and half of the wall had been placed.
"These on the wall are the various samples sent for testing. Each one is different. There are backup copies in the box at the bottom. There are five to ten copies of each on the wall.
On the one hand, these spares are used to replace damaged ones during testing, and on the other hand, they are reserved for us. In the event of an emergency, we can use them directly if there is no time for the factory to produce them.
This is the firearms area, including pistols, rifles, submachine guns, and light machine guns. There are many types. The basic domestic equipment..."
Lin Mo did not rush towards his goal immediately, but listened to Liao Tinghui and looked over bit by bit to understand the development of Wu Liangdong Firearms Repair Institute.
Needless to say, Wu Liangdong worked really hard after taking the job and joining the Intelligence Department. Lin Mo himself was surprised by the richness of the products displayed on the wall.
In the firearms area, most of the firearms equipped in China are basically available. They are not produced by themselves, but obtained through various channels, some are original, some are imitations, and some are even domestically produced privately.
According to Liao Tinghui, these guns were obtained by Wu Liangdong one by one from the confiscated and purchased items at the intelligence office.
After the factory took it to the research center, it was sent here for storage due to limited storage space.
Lin Mo guessed that after acquiring these various guns, the repair shop probably wanted to use Sui to copy and modify them.
Because the gun area is down to the modification area, he saw many new muzzle guns with threads on the muzzle, so that accessories can be installed.
Lin Mo also saw a few submachine pistols. They were no longer made of wood, but were made of plastic. Unfortunately, they still looked very rough. Most likely, the technology or craftsmanship was not good enough.
Most of the guns that have been modified are not pistols, mainly most pistols. The muzzle is flush with the slide. If you want to modify it, you have to change the barrel.
Among the pistols that have been modified the most, Lin Mo got the M1911 with an extended barrel and the shell gun. Yes, the shell gun was also modified by Wu Liangdong.
"Here is the accessories area, including flash suppressors, silencers, suppressors, magazines, drums, etc. Different types are divided into small areas, and the types are quite diverse.
Pistols account for only a small half of the items on the wall. The main reason is that the barrels of existing pistols basically do not support modification. The best option is to use the M1911 with a long barrel.
The repair shop has also made its own barrels, and the progress can be said to be rapid. The problem of barrel explosion has not occurred recently.
But unfortunately, perhaps due to the backwardness of the machine, the service life of the barrel is limited. After one or two hundred rounds, the wear of the barrel becomes serious and it is no longer suitable for general use.
The barrel made in this way is only suitable for use in extended barrels, carbine kits, etc. It is not suitable for the time being and can be replaced on other models of pistols..."
While listening to Liao Tinghui's explanation, Lin Mo followed the crowd and looked forward. Among them, he saw a lot of plastic accessories, some with rough workmanship and some with delicate workmanship.
Lin Mo saw several pistol carbine conversion kits made of plastic material. He took them down and weighed them. They found that the weight was much lighter than before.
However, it has not yet reached Lin Mo’s expectations. Apart from adding some pickup rails that Lin Mo mentioned, the kit is bare.
Later generations did not have anti-slip, grip, weight reduction and other aspects of design, and the production process was not up to standard, with many pores.
Liao Tinghui saw Lin Mo holding this thing and looking at it carefully, and smiled: "The design of this pistol carbine kit is very good, which can greatly improve the shooting stability.
It has a wide range of uses, especially the model equipped with a twenty-shot rapid-fire machine gun. It is much more stable than adding a gun case. With the drum magazine, it can be used as a submachine gun. There is a chance it can be sold to the army.
Unfortunately, the original model was relatively bulky. The use of new materials has greatly reduced the weight, but it is too expensive and probably won't be sold.
It’s a pity... This new material is pretty good and can be used in accessories such as magazines, drums, etc., but it’s too expensive.”
Lin Mo heard this and said with a smile: "Master Liao, this new material has just been researched and it hasn't been long ago! It can only be produced in a small scale. Before large-scale mass production, it is indeed not cheap."
"Oh...how long will it take for this material to be produced?"
Lin Mo could tell that Liao Tinghui was very interested in these various new equipment, otherwise he would not have introduced them in such detail, even paying attention to the repair shop and materials.
Lin Mo explained what he knew, and then Liao Tinghui continued the introduction. At the end of the introduction, he took out a relatively thick silencer.
Of course, this size is only in the pistol silencer area. Among rifle silencers, there are many things thicker than this.
Everyone passed it around and looked at it. Liao Tinghui went into the box and took a spare one, one for each person.
After getting the target silencer, Lin Mo chose other equipment. The first thing he did was to go back and take off the plastic submachine pistol.
I tried it out, but because the submachine pistol didn't have many changes, or not many additions, the material was changed, the weight reduction wasn't too obvious, and the workmanship was rough, Lin Mo gave up.
This chapter is not over yet, please click on the next page to continue reading! Then Lin Mo turned his attention to the magazine drum. After a while of selection, the plastic drum was still rough in workmanship and he had never used it before, so he chose to give up.
Finally, Lin Mo and everyone else took a metal forty-round single drum drum, a large silencer, and a fully automatic submachine pistol in their hands, received the corresponding bullets, and walked to the indoor shooting range.
On the way, Liao Ting found an opportunity, approached Lin Mo, and asked in a low voice: "What do I think about your choice of magazines? You all choose the bigger ones? Although there are more bullets, they weigh a lot, so it will have an impact, right?"
?
There are also guns. I think you just choose the fully automatic one without blinking. Semi-automatic is almost enough, right?"
When Lin Mo heard this, he smiled and said: "Master Liao, there is a saying that is good! If you are poor, you will have tactics, and if you are rich, you will be covered by firepower.
We are not poor, and besides, this little bit of firepower doesn’t cost much. We lack a lot of tactics over there, so let’s use firepower to make up for it!”
After hearing this, Liao Tinghui thought about it carefully and replied: "Although it is a bit biased, there is some truth in it. The aspect of firepower is indeed worthy of our more consideration."
"Hmm..." Lin Mo nodded. As he spoke, he had already arrived at the shooting range. Everyone was getting ready. Lin Mo put a silencer on the gun, tried it and started loading bullets.
To load bullets, this time you don’t have to press each round with your hands. Instead, you use a loader designed by the repair shop to press the bullets.
The design of this loader cannot be said to be very good, and the loading speed is not accelerated. Fortunately, it is more labor-saving, and at least it will not cause pain in the hand.
After the bullets were loaded, everyone checked the guns again and started shooting.
"Tap-tat-tat..." As soon as I fired the gun, I could only hear very weak sounds such as the movement of the sleeve, ejection of the shell, and the impact of the bullet case on the ground. It was very weak and very different from normal shooting.
Lin Mo was very satisfied. With this sound, even if he fired a gun on the street, it would not attract much attention, let alone inside the building.
What's more, it's not a later generation. You can hear the sound of a silencer firing through various videos. This sound is completely different from the sound of a gun. Lin Mo believes that not many people in this era can recognize it.
Seeing this, everyone fired their guns one after another. They each fired a drum, holding a gun with a stream of smoke coming out of the muzzle, and nodded with satisfaction.
Xu Guyu played with it carefully and commented: "The noise reduction effect is very good, it basically eliminates the sound, and the rest, even those who have never heard it cannot recognize it as gunfire.
Unfortunately, the weight is a bit heavy, which limits its use. It is definitely not suitable for use with a naked gun. Otherwise, if everyone is equipped, they can try to avoid making loud noises when making arrests."
Lin Mo listened and said: "Section Chief, the silencer can still be improved. As long as a better inner cavity structure is designed, the volume and weight can be reduced accordingly."
"Hmm..." Xu Guyu nodded. He could see that the role these things could play in the intelligence front was absolutely insignificant. He felt that more attention should be paid to the repair shop.
After Liao Tinghui fired the shot, he was thoughtful and came over to Lin Mo and asked: "Lin Mo, is there any way to make the sniper rifle achieve this level of silencing?
This is very important. If you think about it more, you must know that the sniper rifle is bolted, there is no mechanical sound when firing, and the silencer effect may be better than that of a pistol.
Without the sound of gunfire, my side will have more tactical options and can make more arrangements. In terms of strength, it may be improved to a higher level."
Lin Mo listened and said with a smile: "I really have a way to do this, but I have to start with the bullet and use some means to reduce the speed of the bullet to below the speed of sound.
After all, the sound of gunpowder deflagration can be eliminated with a silencer, but the sound of supersonic bullets cannot be eliminated by adding anything."
"Yes, haha..." Liao Tinghui suddenly realized it, thought about it with a smile, and then asked: "How to achieve it?"
"Hmm..." Lin Mo thought for a moment and said, "The overall general shape and structure of the bullet cannot be changed, otherwise the gun will have to change accordingly.
Under this premise, if you want to reduce the velocity of the bullet, you must either reduce the amount of powder or increase the quality of the warhead. Of course, you can also adjust it at the same time.
My suggestion is to adjust both at the same time, choose an appropriate value between the two, and try to ensure the power at a suitable muzzle velocity.
As for the appropriate muzzle velocity, my suggestion is less than Mach 0.8. Mach 1 is the speed of sound, and Mach 0.8 is about 270 meters per second.
I chose Mach 0.8 or below because I saw a study that showed that in the range from Mach 0.8 to Mach 1, the warhead flight would be very unstable, affecting accuracy."
Lin Mo was thinking about what he had seen in his previous life about subsonic bullets, while telling what he could say and what he could understand. Then he looked up and saw Liao Tinghui, who was holding a small notebook and staring at him after writing down.
"Gone?"
"No more..." Lin Mo shook his head and said with a wry smile: "Master Liao, I know, that's all I can think of."
When Liao Tinghui heard this, he was a little disappointed. He closed his notebook and said, "Let me explain the situation to the repair shop! See if it can be worked out. Unfortunately, they only have the ability to assemble bullets, not full-scale production."
Lin Mo listened, thought for a moment, and said: "Let them think of a solution for production! They are professionals and should have a solution.
However, I have to remind you that regarding warheads, warheads with different shapes, sizes, weights, etc., have a great impact on accuracy, stability, etc. To achieve accurate shooting of a sniper rifle, you need to test as many bullet shapes as possible."
"Okay..." Liao Tinghui nodded, and the two chatted for a while. Lin Mo then took the spare large silencer and left the training ground with Xu Guyu and Liu Zhenshan.
After leaving the training ground, Lin Mo was still on the road, testing the large silencer, mainly to see the effect of the large silencer indoors and outdoors, in different terrain environments.
In the end, everyone was satisfied. After stopping, Liu Zhenshan reported his idea of cooperating with Sun Xinhui to Xu Guyu.
After hearing this, Xu Guyu just frowned and walked forward. Liu Zhenshan waited for a while and couldn't help asking: "Section Chief, can't we do this?"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "This is not..." Xu Guyu shook his head and said: "The main reason is that the situation has been special recently. We have made several big moves, but the agents
However, the headquarters stumbled several times and tried to suppress us during the activities.”
"This...has nothing to do with this, right?"
"Why doesn't it matter?" Xu Guyu asked back, then continued: "In Nanjing, we already have a lot of arrangements, such as coachmen, some gangsters, policemen, etc.
Seriously speaking, the personnel and strength are already too high. It would be extremely taboo for the secret service headquarters to raise the issue and add more fuel to the fire.
Especially the police, they have guns. If something happens... do you understand?
The boss has already brought this matter to my attention. Fortunately, there is no gang involved. The car dealership can also be said to be a business that Lin Mo joined Qiantou. The police are not very close in this regard, and outsiders don't know much, so it's okay.
"
Although he didn't say it directly, Liu Zhenshan still didn't understand, and cold sweat broke out on his forehead. Lin Mo was okay and started thinking about a solution.
"Section Chief, I think the problem lies with the police. After all, they have guns in their hands and are considered an armed force. They do have to worry about some things, but it can be solved by reducing their threat."
"Oh..." Xu Guyu became interested and asked: "How to lower it?"
"Gun..." Lin Mo gave the answer and explained: "The police's responsibilities are mainly security, but the rifles they are equipped with now are serious weapons.
To be honest, it is not necessary for the police to equip themselves with rifles for public security purposes. We can think of a way to replace them with equipment such as revolvers and shotguns, which are more suitable.
The revolver has limited power and a loading capacity of five or six rounds, which is enough to subdue criminals.
Shotguns are powerful, but they are only limited to close ranges. They are basically ineffective at medium and long ranges, but they are enough for them. After all, with the quality of these people, they can't hit them from far away.
Moreover, these two guns, with the technology of the repair shop, will not cause any problems when produced, and this can also help the repair shop develop a lot."
