It wasn't until Chen Er was busy for more than an hour that Li Jun woke up rubbing his head, and said to Chen Er while putting on his clothes: "Second brother, you got up too early, Lao Maozi's Soviet wine yesterday was really strong, and I am still a little dizzy now." &{}{} How do I look at you, it seems like you have nothing to do, you obviously drank yesterday, can you drink better than me, it's too unreasonable. ”

Li Jun nagged that this is taking the basin and preparing to go out to wash his face and brush his teeth, people in this period are still very particular about their personal hygiene, although they can't take a bath every day, but these things will not be missed sooner or later. Watching Li Jun staggering away, Chen Ercai smiled.

Comparing the amount of alcohol with himself is not looking for abuse, but Chen Er is also a little curious, and all he crosses is consciousness, and this body is still the original owner's. Even if I can drink before, I can't bring it here, and after thinking about it for a long time, Chen Er didn't come up with a reason, and in the end it can only be attributed to the big military industrial system, and such a high technology may also be able to play a role in relieving hangover. Anyway, no one can say for sure.

It was already half an hour before Li Jun reappeared in front of Chen Er, and he didn't know whether these boys had gone out to brush their teeth and wash their faces. Or went to do something else. Li Jun looked at the drawings on the table and asked, "Second brother, isn't this the semi-automatic rifle blueprint we researched before?" Don't you say that just change it like this? Li Jun's eyes were like a bell, and he looked absolutely unconvinced.

Chen Er didn't know how to explain it to him, so he could only say: "This is almost what you said, but there are a lot of things that need to be changed, and I am only less than half finished now, and it is estimated that it will be almost the same if I am busy for another day today." Maybe I don't have time to walk around with you today, so you can arrange your own time for today. After speaking, Chen Er began to concentrate on the revision of the drawings again.

For 5o1, Li Jun can't be more familiar, and there is nowhere to go alone, so he can't go to Wenjing's dormitory again. Come and think about it. Li Jun resolutely decided to stay by Chen Er's side, and he was still able to learn a little bit of something, which was better than running around by himself.

So Chen Er changed the picture, while Li Jun watched carefully, and of course he was also responsible for serving tea and pouring water. A morning's time passed quickly, Chen Er stood up and stretched a big lazy waist, he could finally take a rest, but he didn't care about washing his face when he got up today.

Li Jun also admired it very much and said: "Second brother, your drawings are simply too good." There is no trace of any alteration, which at first glance looks like it has been printed by the machine. It seems that I really have to work the drawing field, otherwise I won't even have the opportunity to be your assistant in the future. Of course, Chen Er could hear the exaggeration in Li Jun's words, and the accuracy of hand-drawn drawings would never be able to catch up with the air. It's just talking.

At noon, I went to the cafeteria for lunch and then came back to be busy, and sure enough, it was about the same as Chen Er expected, and at about four o'clock in the afternoon, I finally finished correcting the last drawing. All the drawings for the Type 56 light machine gun are on the table. After Chen Er put all the drawings in order one by one, he finally smiled. That's it. It's the fastest masterpiece I've ever completed.

The next step is the process of making zuò, and Chen Er is ready to hand over the drawings to the master tomorrow. Of course, I will also participate in the production of firearms, and after completing the five or six light machine guns, I can become a third-level military industry, and I don't know what surprises the big military industrial system will bring to me.

At this time, Chen Er couldn't help but recall in his mind the various numbers and structures of the Type 56 light machine gun, etc., so as to facilitate tomorrow's production. Type 56 light machine gun is a light machine gun with a caliber of 7.62 mm designed and manufactured by our own working class and scientific and technical personnel in accordance with the teaching of independence and self-reliance in 1956. Because the Type 56 light machine gun is basically equipped at the squad level, it is also called the Type 56 squad machine gun.

The Type 56 squad machine gun is the main fire weapon in the battle of the infantry detachment, and the best shooting effect is for a single target within 5oo meters, and concentrated fire can shoot the enemy and paratroopers within 5oo meters; Kill and injure group targets within 8oo meters, the warhead still has lethality within 15oo meters, mainly implement short point fire (2-3), long point fire (6-1o), if necessary, continuous fire, after continuous shooting of 3oo bullets, the barrel should be cooled.

Using five or six ordinary bullets, at a distance of 1oo meters, it can penetrate 6 mm thick steel plates, 15 cm thick brick walls, 3o cm thick soil layers and 4o to 6o cm wooden boards, which can be said to have reached a very high level in terms of power, which is also the reason why it has been able to be used for more than 30 years.

The Type 56 squad machine gun is mainly composed of ten parts, each of which has its own independent role.

The barrel is given the direction of flight of the warhead, and the inside of the barrel is the chamber, which is divided into a chamber and a chamber, the chamber is used to hold the bullet, and the chamber can make the bullet rotate when it is advancing. In order to maintain the stability of the flight. There is an air duct on the outside of the barrel to contain a gas regulator to guide the gunpowder gas to impact the piston, and the gas regulator is used to adjust the size of the gunpowder gas that impacts the piston.

There are three air channels and three notches on the gas regulator, and the number 1.2.3 is juxtaposed, which in turn indicates the small, medium and large air channels. Usually set at 2, in severe cold conditions. The shooting or active part is too dirty, and it is set at 3 when it is too late to wipe it. In hot conditions. When the firing or bolt retreat force is too large, it is fixed at 1. There are also connecting tubes, piston barrels and handguards on the outside of the barrel.

The sight is divided by 1-1o long divisions, each long division corresponds to 1oo meters, there is a short division between the two long divisions, and each short division corresponds to 5o meters, and the reverse side of the ruler plate is also engraved with a long division, which is convenient for setting the ruler, and there are runners and notches on the horizontal ruler to correct the direction. There are 7 reticles engraved on the left and right of o, and each reticle is moved at a distance of 1oo meters is equivalent to 2o centimeters of aiming point movement, 2oo meters is 4o centimeters, and so on.

The front sight can be screwed high, screwed off, the front sight can move left and right, there is a carved line on the front sight move to check whether the position is accurate, and there are divisions on the front sight. The width of each division is 1 mm, which is used to determine the momentum of the crosshair.

The receiver is used to accommodate the bolt, to ensure that the bolt is locked in the chamber, and there is a box cover outside the receiver. It is used to cover the receiver and hold the toggle machine, and the connecting slot and connecting pin are used to attach the hammer and the butt to the receiver. Attach sheet metal and wrench to attach and secure cartridges. There is a latching card slot in the receiver. Shell shoot and shoot groove.

The bomb receiving machine is composed of the bomb receiving frame, the bombing frame and the toggle machine. It is used to dispense bullets. The bomb receiving machine base is used to place the bullet belt and ensure its free passage, and the bomb receiving machine base has the following bullet blocking teeth to prevent the bullet belt from falling off, and the pressure tooth is used to press the bullet accurately, and the bullet is separated from the bullet belt. The frame is used to regulate the movement of the slide board. The toggle machine is composed of a plucking slide plate and a long and short plucking arm, and under the action of the frame pulley, the bullet on the bullet belt is transferred to the receiving machine.

The bolt is composed of a frame, a body and a gun handle, which is used to feed the bullet lock to repel the shell and drive the movement of the plucking machine. There are pistons on the frame to withstand the pressure of gunpowder gases, pushing and pressing, the frame is backwards, and there are shaping grooves, bearings, ramming iron grooves, pulleys and round nests on the frame. There are firing pins, grappling hooks, locking long irons and shaped protrusions. There is a hook on the handle to pull the frame to the right.

The reentry machine is used to return the bolt to the forward position. The striking machine is composed of a frame striking blocking iron, a trigger and a safety machine, which interacts with the bolt to hit and hit, and the safety machine is pulled to the front for the safety.

The butt is easy to operate, and the butt contains a re-entry nest and a box nest. A tripod was used to support the machine gun. The cartridge cartridge is used to hold the bullets, and the cartridge contains 2 or 4 cartridge belts, which can hold 1oo. The cartridge has a hook, a lifting ring, a cover plate and a cover buckle.

These materials flashed quickly in Chen Er's mind, and he had a better understanding of the five or six type machine guns, and if he encountered any difficulties when he made the zuò tomorrow, Chen Er would be able to solve them in time. And the most important point is that Chen Er is not ready to ask for this credit, it is all a gift to the master. Anyway, this time I came empty-handed, and it seems that nothing will make the master happier than this.

Seeing that Chen Er had finally called it a day, Li Jun also said happily: "Second brother, this time you can tell the master about your marriage, your marriage can't be sloppy, it must be beautiful when the time comes, how about I plan for you personally?" Chen Er smiled indifferently, this era is like that, Li Jun can't plan to come up with any tricks, you can't expect this kid to conjure up a wedding dress.

Besides, even if Chen Er really managed to make a wedding dress, Murong Wan wouldn't dare to wear it. This era is not so open, unlike girls in the 21st century, as long as the most important position is covered, there seems to be nothing they dare not wear, this is the big difference.

Chen Er thought for a while and said: "I think so, let's make this light machine gun tomorrow, let's gather the strength of the whole factory, and it should be completed in one day." After that, I mentioned my marriage to my master, which can be regarded as double happiness, what do you think? ”

What can Li Jun say, anyway, if Chen Er gets married, if he is not in a hurry, he doesn't need to worry about it. The two of them giggled and chatted about some other things, and it was time for dinner again. Time flies by at the end of the day. Think about it, it doesn't seem to have done anything, life is like this, time flies, in the blink of an eye, people are old, and if you don't cherish it, you will definitely regret the day now. Chen Er is now living with such a mood, and living every day to the fullest is his biggest goal.

Thinking about Murong Wan and Chen Er, they also feel very happy, for the young people of their time, although marriage is already advocating freedom. But because of the face of men and women, most of them basically belong to the type of getting married first and then falling in love, and there are really not many people like them.

Of course, getting married first and then falling in love also has certain benefits, that is, it hone the personality of the two people more, and some bad problems will be slowly changed in daily relationships. And because of the concept of people in this era, divorce rarely occurs, and naturally there will not be so many single-parent families. As an orphan, Chen Er still appreciates this, and in this regard, he is much stronger than modern society. (To be continued!)
