    Thank you brothers for your support!  !  !  !  !  Third update, please collect, recommend, and reward!  !  !  !  !  !  !  !  !  !  !  !  !  ¡ª¡ª  ¡ª¡ª  He came back with the box in his arms. Looking at the box in his arms, he succeeded without guessing.  Li Jun asked carefully: "Wang Yong, you didn't get it secretly while your master was away, right?" Wang Yong took a sip of water. He walked a little hastily along the way. He was really tired. Take it easy.  His tone was: "I am that kind of person. The master gave this to me personally, and the master also asked me to bring a message to Chen Er. Our country must have its own sniper rifle. You can do it boldly and safely."  , These are the master's original words, absolutely without any adulteration. " At this time, Li Jun finally felt relieved, but soon they would dismantle the telescope, and Director Zheng would come to find him again, which would be a big trouble.  Big.  Wang Yong looked at Chen Er and asked: "What are we going to do next? Can we just remove the telescope lens and install it on your sight?" Chen Er opened the box and looked at the telescope inside. It was actually an American pair.  It is a telescope made by a Japanese telescope, and it is well preserved. No wonder Director Zheng regards it as a treasure. It is really a good thing.  Chen Er first made a simple gesture and then said: "The only lens we can use at the moment is this telescope, so this time we can only succeed but not fail. Let me think about it carefully."  Li Jun and Wang Yong have not dabbled in this matter at all, and now Chen Er can only rely on Chen Er to figure it out.  After a while, Chen Ercai said: "You probably don't know much about this sight. Let me give you a general introduction first. Ours uses the optical imaging principle, so it is called an optical sight. There is nothing wrong with it.  It can be said that the key is the structure of this sight. " "The main function of the optical sight is to use the optical lens to image, overlapping the target image and the aiming line on the same focus plane, even if the eye is slightly offset.  Affects the aiming point. Usually optical sights can magnify images. The scope I designed has a magnification of 4 times, which means that it can magnify the distant scene to four times. It is already preliminary and can meet the needs of the battlefield.  "An optical sight has at least three optical lens groups, one is the objective lens group, one is the correction lens tube group and the eyepiece group, and there may be other lens groups responsible for collecting light, so when the objective lens is larger,  The scene in the sight should be brighter. The eyepiece group is responsible for changing these light rays back to parallel light, allowing the eyes to focus and creating the largest field of view. The correction lens tube group corrects the image of the objective lens from upside down to left and right.  into the correct direction, and is responsible for adjusting the magnification. The position of the aiming line can be at the first focus plane in front of the correction lens group, or the second focus plane behind it, and the windage adjustment knob and the height adjustment knob are used to control the correction.  The left and right, high and low, and front and rear positions of the lens tube group. " "A high-end sight may have more than 9 lenses in the body. With appropriate coating, the light transmittance may exceed 95%. But even if the light transmittance is not.  At such a high level, the brightness in the field of view may still be higher than that of the naked eye, because the light-gathering area of ??the objective lens is generally larger than the light-gathering area of ??the eye. This is the working principle and method of use of the sight, but the specific operation is.  It¡¯s just not that simple anymore.¡± After listening to Chen Er¡¯s words, Wang Yong and Li Jun were stunned. This was the first time they had heard of these theories, and they still didn¡¯t understand many of the terms, but since Chen Er said that.  Well, I guess he has a way to solve these problems.  Li Jun simply said: "Second brother, it's useless for you to tell us these things now. I think you should just tell us what we can do. All we have to do is follow your orders." Chen Eryi thought the same thing.  If you tell them this way, it's probably just a matter of paper. You have to wait until you finish the scope. Then go to the shooting range to demonstrate it, and they may accept it more easily.  After figuring this out, Chen Er worked with them to carefully remove the lenses on the telescope one by one. However, the lenses of the telescope were much larger than the scope he designed, and there was no way to fit them in for a while.  .  Li Jun suddenly suggested: "Second brother, how about we use a machine tool to grind this lens a little smaller?" Chen Er refused without hesitation: "No, these lenses have been specially processed.  Yes, if it is processed on a machine tool, small cracks may appear, and all the previous efforts will be wasted. I think I should make a new scope from scratch based on the lens.Wang Yong also said: "Chen Er, is that necessary? I think Li Jun's idea is feasible. As long as we are careful, there should be no problems."  "Chen Er shook his head and continued: "This is not as simple as you think. This kind of optical sight is all about precision. Can you guarantee that the lenses you polish are exactly the same? It is absolutely impossible to do it manually.  arrived.  " When Chen Er said this, Wang Yong and Li Jun were both stunned. They really didn't understand this, so they could only listen to Chen Er. Chen Er found some new raw materials again, and faced the machine tool.  He started to get busy. This time, he designed the scope according to the size of the lens. Although it was slightly less beautiful, it had no impact on practicality at all. And Chen Er this time.  A dust cover was deliberately added to the scope. This was also an issue that had been ignored before. It was only when they saw the dust cover of the telescope that they suddenly thought of it. In the anticipation of Li Jun and Wang Yong, Chen Er was busy.  One afternoon, as soon as the machine stopped, Li Jun and Wang Yong came over immediately and asked in unison: "How is it? Is it successful?"  Chen Er wiped his sweat and said, "What do you think? This afternoon cannot be wasted."  "With that said, he picked up the completed sight on the table and handed it to Li Jun's hand. Li Jun quickly put it in front of his eyes and looked at it. While looking at it, he said: "Second brother, don't say anything yet.  , this thing is really good, you can see things in the distance quite clearly, I think this is no worse than that telescope.  "Wang Yong also hurriedly took it and took a look. Both of them were amazed. " Chen Er is nothing but a little tired. Besides, this scope has the function of a telescope, which is nothing. Its real use  Only when combined with this sniper rifle can it be truly reflected. After Li Jun and Wang Yong had seen enough, Chen Ercai took the scope and carefully installed it on the upper part of the sniper rifle, a complete Type 85 sniper rifle.  Finally it appeared in front of them. Chen Er said: "How about it, this is a sniper rifle, which uses an optical sight to find the target, and then locks on the target for a fatal blow.  "Li Jun picked up the sniper rifle and looked at it, then looked into the distance with one eye through the scope, and said, "Second brother, as long as I identify the target through the scope and pull the trigger, I can shoot the target.  It's done. Otherwise, let's go to the shooting range to test it out.  " Chen Er took the sniper rifle and said, "That's fine. By the way, I will also make some basic corrections on this gun.  "Although the sniper rifle has been produced, the calibration still needs to be completed through live ammunition shooting. Taking the twenty rounds of bullets that had been prepared, the three people went to the shooting range. Li Jun took the initiative to hold the sniper rifle  , it will be time for him to show off his skills again, and he is full of enthusiasm for shooting. Soon he arrived at the shooting range, and while loading bullets into the magazine, Chen Er said to Li Jun: "This sniper rifle.  If the recoil is a little larger than that of ordinary firearms, you will have to hold the butt of the gun with your shoulder when shooting to avoid shoulder injury.  Li Jun said with a smile: "I know, second brother, don't worry, I won't make fun of my body."  "After loading the magazine, Li Jun walked towards the shooting position. He quickly lay down there, put the gun in place, and pulled the bolt hard. Then he looked through the scope with one eye.  He hit the target in the distance, and sure enough, the target suddenly became much clearer. After Li Jun aimed at the red heart, he adjusted his breathing and pulled the trigger. He only felt a strong force coming towards his shoulder. Luckily for him.  He had to hold the gun butt, otherwise he might really be slightly injured. With the experience of the first shot, Li Jun fired four more shots. There were not many bullets in the first place, so he could only use them sparingly.  After putting away the gun, Li Jun took his target over. Sure enough, although there was a slight deviation, the five shots still had 45 and 6 rings. This was definitely a breakthrough in her previous results.  , not to mention that the firearm has not been calibrated yet. The next one is Wang Yong. He also shot five times and his results are similar to Li Jun. Naturally, he is quite satisfied with this sniper rifle. He usually doesn¡¯t have many opportunities to shoot.  What's more, he also knows his own level. If he hadn't used this sniper rifle, he would have been pretty good if he could hit more than thirty rounds. The last person to appear was Chen Er. He once again filled up his magazine and fell down.  In the shooting position, because Chen Er had already seen Li Jun and Wang Yong's target, the impact point of the bullet was obviously a little lower. Besides, this is only a 100-meter target, and there is no anything involved in the cave.  Problems with wind speed and direction. Chen Er quickly completed the calibration of the firearm. Pulling the bolt and pointing the red heart at the target was the trigger. Chen Er could clearly see through the scope that there was a small hole in the center of the red heart.    Next, Chen Er fired four more shots in a row, but there was still only one small hole in the target, and all five shots hit the same place. It seemed that his calibration of the sniper rifle was relatively successful.  After Chen Er got back the target, Li Jun and Wang Yong looked at the handle and didn't know what to say. With these five guns and one hole, there couldn't be many such sharpshooters in the army.  Chen Er said with a smile: "Well, you know the benefits of a sniper rifle. I am not a strictly trained soldier. I just mastered the essentials of using a sniper rifle. With this target shooting performance, I can definitely compete with anyone."  Compared with the previous one, this is the power of the sniper rifle.¡±
