After Lin Mo finished drawing, he handed the drawing to Wu Liangdong and introduced: "Old Wu, this is the butt stock I drew, please take a look.

This is a retractable butt stock. I have marked the general design and parameters for you. You can just follow it.

However, there is a lack of the part connected to the grip on it, so you need to go down and design it. You can use guide rails or other designs as long as it does not affect your use."

After hearing this, Wu Liangdong nodded and looked carefully at the design drawings given by Lin Mo. He found that the structure was quite simple and it was not a problem for them. Moreover, Lin Mo also marked various things clearly.

After carefully putting away the drawings, Wu Liangdong spoke, "Young Master Lin, there is no problem with this butt stock. The structure is quite simple and can be made in two or three days.

But if you use guide rails, you need to modify the gun, which may be a bit troublesome. I want to put the butt stock on the grip."

After hearing this, Lin Mo nodded and said, "This is OK for you. As long as it does not affect your use or carry around, you can design it as much as you think it is easy to use.

After the design is completed, first produce thirty or forty pieces and send them to the store. I will arrange for someone to try it out. If there is any problem, they will give it back to you and you will make modifications."

After hearing this, Wu Liangdong nodded, and the two of them talked about some details, trying to avoid any problems.

After the two talked, Lin Mo had been writing and drawing things after coming in. Finally, Lin Mo put down his pen and sorted out a bunch of drawings.

After doing this, Lin Mo said to Wu Liangdong: "Old Wu, I have other things to come to you today. I will tell you first.

I need you to help me make a batch of gun muzzle accessories, which are retractors for sound and flame silencing and reducing gun recoil.

There are some other things, you can take a look at the sound silence and flame suppression and the retardation device first!" After Lin Mo said that, he took out a few drawings and handed them to Wu Liangdong.

Wu Liangdong took it and looked at it, and his head was filled with questions. Although he could see how these things were to be done, he really didn't know what the use of these things was, so he had to look at Lin Mo awkwardly.

Lin Mo saw Wu Liangdong's question and said, "Old Wu, let me tell you the principle of these things! Because I need you to experiment with me and see how it works well.

I have read some foreign information and made them based on the principles and some descriptions in it. I don’t know what the effect is.”

Upon hearing this, Wu Liangdong put the drawings in his hand on the table and said, "Young Master Lin, then tell me! I really don't know how to do this thing."

Lin Mo heard this and explained: "Okay, I'll start with you from the beginning.

The flame and recoil of this gun are caused by the combustion of gunpowder in the bullet, and the sound is caused by the friction between the gas and the bullet and the air when the gun cavity is shot and the bullet is out of the cavity.

But this time we don’t consider other factors, just consider the gas burning from gunpowder, and only talk about the part at the muzzle."

Next, Lin Mo explained the principles of silencer, flame suppressor, and muzzle retractor to Wu Liangdong.

A muffler is equivalent to a tube, but a different cavity is separated from it, locking the gas inside, reducing its sound to reduce the sound.

Different cavity shapes have different effects that hinder gas, and the sounds emitted by gas inside are also different, which can change the tone and make people unable to hear it is gunshot.

Whether it is to reduce gunfire or change gunfire, it can be very good to avoid people's discovery, so as to protect themselves and avoid causing confusion.

Lin Mo even felt that in this era, people cannot use any way to hear the sound changed by the silencer. This change of tone is more useful to a certain extent than reducing the sound.

So Lin Mo drew a lot of different cavity shapes for Wu Liangdong, and asked him to try them all after he went down.

It is not difficult to make this muffler. Just find a circular metal pillar of the right size, first drill a bullet hole in the middle, and then you can carve different cavitys into the metal pillar.

After carving, put an iron pipe on the outside and put it at the muzzle, and you can start using it.

A flame suppressor is even simpler. It is to make the gunpowder gas spray in different directions by opening a groove, reducing the flame light on the front.

However, the amount of fire light decreases varies from gun to gun and varies from groove shape. Some can be completely eliminated, while others can only reduce it, but more or less can play some role.

The muzzle retractor guides the gas in different directions through opening holes or slots, allowing the gas to produce a force on the gun and reduces a certain amount of recoil.

The most common thing is to open an upward hole or groove, spray upwards through gas, and apply a downward force to the muzzle to reduce the upward rise of the muzzle.

Of course there are other designs. Lin Mo only knew a rough idea. After talking about the general principles, he asked Wu Liangdong to go down and explore it on his own.

Lin Mo said this retractor, just to add something to the muzzle of M1911A1 in his hand for daily use and reduce the muzzle upwards.

After explaining the principles and general structure and production methods of these three things to Wu Liangdong, he asked: "Old Wu, how about it? Do you have any questions?"

Upon hearing this, Wu Liangdong smiled and shook his head, saying, "No, Young Master Lin, you have already explained it to me very clearly.

But this... the muzzle of the M1911A1 pistol did not stick out, and this... it was a bit difficult to install things."

Hearing this, Lin Mo frowned. Although he had realized this problem before, he also asked Scott to get a batch of extended barrels for himself.

Unfortunately, Lin Mo did not expect to use it so soon, so he put it on that list. It would be impossible to get all the lists together in a short period of time.

Now it seems that Lin Mo has to release another blood, so he asks Scott to help him get a batch of extended barrels.

Thinking of this, Lin Mo said to Wu Liangdong: "Old Wu, don't worry about this. I will find someone to get a batch of extended M1911A1 long barrels.

Now you use a rifle to study it first, try the effect on the rifle first, and send it some here, I'll ask someone to try it."

After hearing this, Wu Liangdong nodded and said, "Young Master Lin, then I will have no problem. The first batch of samples should be available in a few days."

Seeing this, Lin Mo continued, "That's good, Lao Wu, don't just limit yourself to what I have drawn for you. You can try it more according to your own ideas.

You can try to integrate these three things together, such as silencers, which also have a certain flame-relieving effect. Adding a flame-relieving effect may achieve a very good sound-relieving effect.

The flame suppressor and the muzzle retractor are both used to dig the gunpowder gas through slotted holes, so that the two functions do not conflict. You can also work hard on this.

As for the cost of trial production, you can come to me for reimbursement, or even make good things, and I can also give you a considerable reward. Don't worry, I won't let you lose money."

Hearing Lin Mo say this, Wu Liangdong showed joy on his face and hurriedly said, "Young Master Lin, don't worry, we will definitely try to make something that satisfies you."

Lin Mo nodded and said, "That's good. Remember to keep these things confidential, including what I asked you to do in the past and in the future. Don't leak them out.

These things may be involved in some things in the future. I don’t want you to be involved, it will not do you good.”

After hearing this, Wu Liangdong smiled and said, "Don't worry, Mr. Lin, we have experience..."

Lin Mo nodded when he heard this. If it weren't for knowing that Wu Liangdong and the others had secretly imitated guns before and had not been discovered by others, they would definitely have the awareness of confidentiality. How could Lin Mo hand over these things to them?

After Lin Mo explained the drawings to Wu Liangdong again, he finally took out the last stack of drawings and handed them to Wu Liangdong.

Wu Liangdong took it and found that a stack of drawings had drawn something. Wu Liangdong could see that it was a gun.

It's just a bit strange. It's called a pistol, but it's called a submachine gun, but it looks like a pistol in some places.

Wu Liangdong looked at the introduction written by Lin Mo and knew that it was a pistol, but he changed the shell of the pistol to make it look like a submachine gun.

After reading it, Wu Liangdong felt that it was not a big problem, so he said, "Young Master Lin, this problem is not a big problem. We can just make a shell according to your design."

Lin Mo nodded and said, "That's good. You can use metal first to make it look like the weight. If it's too heavy, replace some parts inside with wooden ones."

After saying that, Lin Mo told Wu Liangdong about some of his detailed designs and requirements.

Lin Mo drew a pistol kit based on a pistol that can convert a pistol into a carbine. To put it bluntly, it is to change the pistol to a shell.

A magazine well was added to the front end of the gun, which could be inserted into the magazine as a grip. A pop-up stock was added to the gun body, which completely copied the design of later Americans.

Originally, Lin Mo had never thought about getting this thing out, but today's Lin family information made Lin Mo smell the danger and could only try his best to strengthen the strength of his subordinates.

After all, even Liao Tinghui and the others were defeated. They are still in the dark, so Lin Mo dared not put all his hopes on the Military Intelligence Department.

What's more, there is still a problem with the Military Intelligence Department now. If this matter is not resolved, it may be worse to let them participate.

So Lin Mo could only think about the worst. In order to protect himself and his classmates, he used all the means he could think of to strengthen the abilities of his subordinates just in case.

This set of kit that converts the pistol into a carbine can not only effectively increase the stability of the pistol, but also make it more convenient to operate the pistol and more stable to shoot.
