After Lin Mo finished drawing, he handed the drawing to Wu Liangdong and introduced: "Old Wu, this is the gun butt I drew, take a look.
This is a retractable gun stock. I have marked the general design and parameters for you. You can just follow it.
However, the part that connects to the handle is missing, so you need to design it. You can use guide rails or other designs, as long as it does not affect the use."
Wu Liangdong listened, nodded, and carefully looked at the design drawings given by Lin Mo, and found that the structure was quite simple, which was not a problem for them, not to mention that Lin Mo also marked various things clearly.
After Wu Liangdong carefully put away the drawings, he said: "Master Lin, there is nothing wrong with this gun butt. The structure is quite simple and can be made in two or three days.
It’s just that if you use a guide rail, you need to modify the gun, which may be a bit troublesome. I want to put the butt of the gun on the grip. "
Lin Mo listened, nodded, and said: "It's up to you. Anyway, as long as it doesn't affect the use and carrying, you can design it however you think it will be useful.
After the design is completed, produce thirty or forty pieces first and send them to the commercial bank. I will arrange for someone to try them out. If there are any problems, they will give them feedback to you and you can make modifications."
After Wu Liangdong listened, he nodded, and the two discussed some more details, trying to avoid any problems as much as possible.
After the two of them talked, Lin Mo had been writing and drawing things since he came in. Finally, when he was done, 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 for today, so I'll tell you first.
I need you to help me make a batch of gun muzzle accessories, which are muzzle brakes used to silence and suppress the gun's recoil.
There are some other things, you should take a look at the silencer, flame suppressor and muzzle brake first!" After Lin Mo finished speaking, he took out a few drawings and handed them to Wu Liangdong.
Wu Liangdong took it and took a look, and his head was filled with questions. Although he could see how to make these things, he really didn't know what they were used for, so he had to look at Lin Mo awkwardly.
Lin Mo saw Wu Liangdong's doubts and said, "Old Wu, let me tell you the principles of these things! Because I need you to test them for me to see how to make them effective.
I have read some foreign information and created these things based on the principles and some descriptions in them. I don’t know what the effect will be.”
Upon hearing this, Wu Liangdong put the drawing in his hand on the table and said, "Master Lin, please tell me! I really don't know how to make this thing."
Lin Mo listened and explained: "Okay, I'll tell you from the beginning.
The flames and recoil of this gun are caused by the burning of gunpowder in the bullet, and the sound is caused by the gas in the gun chamber and the bullet exiting the chamber, as well as the friction between the bullet and the air.
But this time we don’t consider other factors, we only consider the gas generated by the burning of gunpowder, and we only talk about the part of it at the muzzle.”
Next, Lin Mo explained the principles of silencers, flash suppressors, and muzzle brakes to Wu Liangdong.
A muffler is equivalent to a pipe, but it is separated into different cavities to lock the gas inside and reduce its sound from being transmitted out, thereby reducing the sound.
Different cavity shapes have different effects on gas obstruction, and the sound emitted by the gas inside is also different, which can change the timbre so that people cannot hear the sound of a gunshot.
Whether you reduce the sound of gunfire or change the sound of gunfire, you can avoid being discovered by others, thereby protecting yourself and avoiding causing confusion.
Lin Mo even felt that people in this era had no way to hear the changed sound of the muffler. To a certain extent, changing the tone was more effective 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.
Making this silencer is not difficult. Just find a round metal pillar of suitable size, drill a bullet hole in the middle, and then carve out different cavities against the metal pillar.
After carving, put an iron pipe on the outside, install it on the muzzle, and you can start using it.
A flame suppressor is a simpler thing. It uses slots to allow the gunpowder gas to spray in different directions to reduce the frontal flame.
However, the amount of fire reduction varies from gun to gun and the shape of the slot. Some can be completely eliminated, while others can only be reduced, but it can have some effect.
The muzzle brake guides the gas in different directions through openings or slots, allowing the gas to exert a force on the gun and reduce a certain amount of recoil.
The most common method is to open an upward hole or slot, spray gas upward, and exert a downward force on the muzzle to reduce the rise of the muzzle.
Of course, there were other designs, but Lin Mo only knew a rough idea. After giving some general principles, he let Wu Liangdong explore on his own.
Lin Mo mentioned this muzzle brake just because he wanted to add something to the muzzle of the M1911A1 in his hand for daily use and reduce the muzzle rise.
After explaining the principles, general structure, and production methods of these three things to Wu Liangdong, he asked: "Old Wu, how are you? Do you have any questions?"
When Wu Liangdong heard this, he smiled and shook his head, saying: "No, Master Lin, you have already made it very clear to me.
It's just that...the muzzle of the M1911A1 pistol is not extended, so...it's a little difficult to put things on."
Hearing this, Lin Mo also frowned, although he had been aware of this problem before and specifically asked Scott to get himself a batch of extended barrels.
It's a pity that Lin Mo didn't expect to use it so soon, so he put it on the list. It was impossible to put it all together in a short time.
Now it seemed that Lin Mo had to draw blood again and asked Scott to quickly get him 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 barrels.
Now you conduct research on the rifle first, try the effect on the rifle first, and send some over by the way, I will have someone try it."
Wu Liangdong listened, nodded, and said: "Master Lin, then I have no problem. The first batch of samples should be available in a few days."
Seeing this, Lin Mo continued: "That's good, Old Wu, don't just limit yourself to what I drew for you, you can try out more according to your own ideas.
You can try to integrate these three things together, such as a silencer, which also has a certain flame suppression effect. If you add a flame suppressor, you may be able to achieve very good noise suppression and flame suppression effects.
Both the flash hider and the muzzle brake use slots and openings to guide gunpowder gases. There is no conflict between the two functions. You can also work hard in this regard.
As for the cost of trial production, you can come to me for reimbursement, and even if you get something good, I can also give you a large reward. Don't worry, I won't let you lose money."
Hearing what Lin Mo said, Wu Liangdong's face showed joy and he quickly said: "Young Master Lin, don't worry, we will definitely produce something that satisfies you."
Lin Mo listened, nodded, and said: "That's good, remember to keep these things confidential, including the things I asked you to do in the past and in the future, and don't leak them to the outside.
These things may be involved in some things in the future, and I don’t want you to be involved, it won’t be good for you.”
Wu Liangdong listened and said with a smile: "Don't worry, Master Lin, we have experience..."
Lin Mo heard this and nodded. If he hadn't known that Wu Liangdong and the others had secretly imitated guns before and had not been discovered by anyone, so they must have a sense of confidentiality, how could Lin Mo have left these matters in their hands.
After Lin Mo explained the drawings to Wu Liangdong, he finally took out the last stack of drawings and handed them to Wu Liangdong.
Wu Liangdong took it and took a look and found that there was something drawn on a stack of drawings. Wu Liangdong could tell that it was a gun.
It's just a little strange. It's a pistol, but it's different from a pistol. It's a submachine gun, and it looks like a pistol in some places.
Wu Liangdong read the introduction written by Lin Mo and knew that it was a pistol. He just changed the shell of the pistol to make it look like a submachine gun.
After Wu Liangdong looked at it, he felt that it was not a big problem, so he said: "Master Lin, this is not a big problem. We can just make a new shell according to your design."
Lin Mo listened, nodded, and said: "That's good, you go and make it with metal first, take it out and see how the weight is. If it's too heavy, replace some parts inside with wooden ones."
After speaking, Lin Mo explained some of his detailed designs and requirements to Wu Liangdong one by one.
What Lin Mo drew is a pistol kit based on a pistol, which can convert the pistol into a carbine. To put it bluntly, it just replaces the pistol with a shell.
A magazine well was added to the front end of the gun, which could be used as a grip by inserting a magazine. A pop-up butt was added to the gun body, which completely copied the later American design.
Originally, Lin Mo had never thought about getting this thing out, but today's information about the Lin family made Lin Mo smell the danger, so he could only try every means to strengthen the strength of his subordinates.
After all, those people, even Liao Tinghui and the others, were in trouble and were still in the dark. Lin Mo didn't dare to put all his hopes in the Military Intelligence Department.
What's more, there is still a problem with the Military Intelligence Office. If this matter is not resolved, it may be worse if they are involved.
Therefore, Lin Mo could only think about the worst, and in order to protect himself and his classmates, he used all means he could think of to strengthen the abilities of his subordinates, just in case.
This kit that converts a pistol into a carbine can not only effectively increase the stability of the pistol, but also make it easier to operate the pistol and make shooting more stable.
It can also be very well adapted to large-capacity drums and silencers, increasing firepower continuity and improving concealment. After all, large drums and silencers are very heavy, and simply adding them to a pistol will definitely affect shooting.
