Seeing that Chen Er finally finished painting the last bullet, Li Jun cautiously picked up a few more and looked at them and asked: "Second brother, this is too little, what can these dozen bullets do, if they haven't hit yet, they are gone, I don't think it's useful except for being a little fresh." ”

Chen Er glanced at him and said, "This was not originally intended to prepare for regular battles, and now that you don't understand, when I have studied the special gun, it will be able to wield the true power of these bullets." Chen Er's words made Li Jun suddenly say that he was in a fog, and there are special guns, don't all guns look like that, Li Jun really doesn't know what Chen Er is going to do now.

Chen Er can't care so much, he has been thinking about sniper rifles in his mind, and sniper rifles are also a very important part of individual weapons, because sniper rifles have a long range and high accuracy, especially in some specific environments and battles, they can definitely play an unexpected role. So a good sniper on the battlefield is definitely an enemy nightmare, and it is also an indispensable storage on the battlefield.

I quickly searched for information about various sniper rifles in my mind, and if it was too advanced, don't think about it, even if the current technology is made, it may be difficult to meet the design standards. After pondering for a long time, Chen Er set his target on the Type 85 sniper rifle, which is copied from the former Soviet Union Dragnov sVd sniper rifle, which is basically the same as the sVd in terms of principle, structure and tactical performance. The air-conductive automatic mode, bolt rotary locking, 1O magazine feeding, and 4x optical sight are already able to basically meet the current requirements.

The Type 85 sniper rifle has a caliber of 7.62mm, an initial bullet of 83om/s, and an ammunition of 7.62x54mm bullets, with an effective range of 1ooom and a shot of 3o/min. The total weight of the gun is 4.4kg, the length of the gun is 122omm, the width is 17omm, and the height is 178mm. It adopts an optical sight, the weight of the sight is o.5kg, the magnification is 4 times, and the angle of view is 6 degrees. These numbers popped out of Chen Er's mind like a movie.

Although in a fundamental sense, the Type 85 sniper rifle cannot be regarded as the best sniper rifle, but for the current era, under the limitations of technology, the Type 85 is already a very good choice, at least the current process can complete the production of the whole gun.

After making up his mind, Chen Er began to draw drawings, although he said that he could make this gun even without drawings, but in order to be able to mass produce in the future, drawings must still be available. Compared with ordinary guns, the requirements of sniper rifles are also higher, the design is more complex than ordinary guns, and it naturally takes a little longer to draw on drawings. A morning passed, and Chen Er had only completed a small part.

I hastily went to the cafeteria to eat some food, and quickly went back to continue drawing, and it was not until eight o'clock in the evening that all the drawings were completed. Rubbing his eyes and stretching his waist by the way, he was stunned when he saw the time, it was already eight o'clock, and he hadn't eaten dinner yet, so it seemed that he was hungry again tonight. Just when Chen Er was a little hesitant, Murong Wan suddenly walked over with a lunch box and said, "Forget to eat again, let's eat it for you, I saw that you had been drawing something seriously just now, so I didn't come to disturb you." ”

Chen Er hurriedly took the lunch box in Murong Wan's hand, feeling that the lunch box was still hot, Chen Er said embarrassedly: "Thank you, otherwise I would have to go to bed hungry again tonight." Seeing Chen Er eating happily, Murong Wan's heart was full of joy, her eyes unconsciously glanced at the drawings on the table, and she picked up one at random and looked at it for a long time and didn't understand, so she could only ask: "Chen Er, what is this, why does it look weird, it looks like a telescope, but the telescope is not like this." ”

Chen Er looked up and saw that Murong Wan had actually just gotten the blueprint of the scope, and he didn't know how to explain it specifically for a while, so he had to take a sip of water and say, "This is actually a telescope, but it's mounted on a gun, so you can see a farther target." Saying that, Chen Er still gestured on the side, and after explaining, Murong Wan probably understood a little, and finally stopped asking.

Chen Er also knew that it was still difficult to explain it to her, because the sniper rifle involved a lot of problems, and it would be unclear for a while, and when he made the whole gun out and demonstrated it to them, he would definitely understand. After eating, Chen Er finally felt much more comfortable, this is really in response to that sentence, people are iron, rice is steel, and if you don't eat a meal, you will be hungry and panic.

Chatting with Murong Wan for a while, Chen Er went back to the house to prepare for rest at about nine o'clock, and he had to get up early tomorrow, this sniper rifle was different from others, and he didn't worry about others coming to help, it was estimated that it would take about a week to complete the production of the entire gun parts. There was nothing to say all night, and at six o'clock the next morning, Chen Er was busy, and the first thing to be completed was the barrel part.

It is not an exaggeration to say that the barrel can be called the soul of the sniper rifle, after all, the sniper rifle is based on accuracy, so the precision required for the manufacture and processing of the sniper barrel is higher than that of the general barrel, and the quality and weight are also more than the requirements of the traditional barrel, so as to reduce the change from the impact point of the first ammunition after firing, especially the high temperature and expansion of the barrel due to continuous firing, and the angular fraction value of the impact point of the bullet on the surface of the bullet will gradually increase. It is worth mentioning that the chamber of the sniper barrel does not have an electrochrome plating anti-rust procedure like the chamber of an assault rifle or the main rifle, which is also a consideration to reduce the impact accuracy.

The barrel is actually only connected to the receiver when it is assembled, that is, the barrel is "floating" on the gun, which has the advantage that the barrel can remain undisturbed by the gun handguard, tripod, gun strap, and even the sniper's "hand". In principle, it is used as a fireproof cap to suppress the fire of the muzzle when firing, but in fact it is used to counterweight and protect the barrel from being hit without affecting the accuracy of the shot. Some sniper rifles even have ribs on the barrel to maintain tension to prevent the barrel from being affected by high temperatures.

Because the barrel of a sniper rifle is much longer than that of an ordinary rifle, Chen Er is very attentive to the processing of the barrel, and after a barrel is continuously processed by him on the lathe for more than two hours, Chen Er wiped the sweat on his head and smiled with satisfaction. It is said that everything is difficult at the beginning, and this barrel part is finally completed. Compared with the barrel, the easiest thing to make is the wooden butt, because the wood is easier to process, and in less than half an hour, the wooden part of all the butts is completed.

The next thing is the production of other parts of the firearm, Chen Er has been immersed in this state of getting up early and going to bed late for a week, and even Li Jun is a little worried about Chen Er's abnormal behavior. looked at Wen Jing who was sitting next to him and said: "Wen Jing, did you say that the second brother was stimulated by anything, this has been like this for a week, and sometimes there will be some laughter suddenly, do you want to apply to find a doctor for him to see, I am really afraid that he will collapse sooner or later if he continues like this." ”

Wen Jing thought for a while and said: "I don't think it should be as strict as you said, although Chen Er's appearance is a little abnormal during this time, but he eats on time every day." And I heard Wan'er say that Chen Er is developing a kind of gun, anyway, there must be no problem mentally, so don't make a big fuss. When you have half of Chen Er's efforts, I guess you will be able to research something. ”

Li Jun heard Wen Jing pull the topic to himself, so he hurriedly snorted and said, "It's okay, I'm just worried that the second brother's body can't bear it, since he is researching weapons, there is nothing to worry about." I still know the second brother very well. Once this thing is done, it will definitely not be successful, but I look at the progress of the second brother, and it is estimated that this gun is almost completed. ”

After a week's work, although Chen Er is still in good spirits, his eyes also have big dark circles, his clothes are dirty every day, and his beard has not been shaved for three or four days. However, Chen Er didn't seem to notice this, and today he saw that it was about to be completed, and his mood was not excited, but it was fake.

As the parts in his hand slowly took shape, the main part of the firearm was finally completed, Chen Er finally breathed a sigh of relief, the only thing missing now was the scope, because he didn't have lenses here, so he just completed the overall production of the scope, and the problem of the lens could only be found in another way.

Looking at these parts in front of him, Chen Er's heart couldn't help but be filled with a sense of accomplishment, this week was also swept away because of the tiredness of busyness, and after putting away all the parts, Chen Er finally noticed his image in the mirror, which scared him.

The wrinkled clothes, the messy head, the stubble on the face, and the hands were even blacker, as if he had just crawled out of the mine, Chen Er couldn't care about anything else now, so he quickly brought water to freshen up, and changed his clothes before he appeared outside again. Li Jun saw Chen Erhui's old appearance, so he walked over and said happily: "Second brother, you should have succeeded in looking like this, but this time has frightened us, at first we thought you had a mental problem, and we almost applied to find a doctor for you." ”

Listening to Li Jun's concerned words, Chen Er's heart couldn't help but warm, this is a brother, but thinking back to his appearance just now, it's no wonder that they are so worried about themselves.
