Sure enough, after a while, Wang Yong came back with the box, looking at the box in his arms, he didn't have to guess that it was a success. Li Jun asked cautiously: "Wang Yong, you won't secretly take advantage of your master's absence, right?" Wang Yong took a sip of water, he was a little anxious along the way, he was really tired, and he said with a sigh of relief: "I'm that kind of person, this is handed over to me by the master personally, and the master also asked me to bring a message to Chen Er, our country must have its own sniper rifle, although you can do it boldly and with confidence, this is the master's original words, and it is definitely not adulterated." ”

At this time, Li Jun was finally relieved, but after a while, they dismantled the telescope, and Director Zheng found it again, and it would be a big trouble. Wang Yong looked at Chen Er and asked, "How do you get it next, can you just remove the telescope and install it on your scope?" ”

Chen Er opened the box and looked at the telescope inside, it was actually a pair of telescopes made in the United States, and it was quite well preserved, no wonder Director Zheng would store it as a treasure, this is really a good thing. Chen Er first made a simple comparison before saying: "The only lens we can use at the moment is this telescope, so this time we can only succeed and not fail, let me think about it." ”

For things like scopes, Li Jun and Wang Yong didn't get involved in it at all, and now they could only rely on Chen Er to figure out a way. After a while, Chen Ercai said: "You shouldn't know much about this scope, I'll give you a general description first." We use the optical imaging principle, so it is called an optical sight, which has nothing to say, the key is the structure of this sight. ”

"The most important function of an optical sight is to use an optical lens to imprint the target image and the line of sight on the same plane of focus, even if the eye is slightly offset, it will not affect the aiming point. Usually the optical sight can magnify the image multiple, but the scope I designed is 4 times magnification, that is to say, it can fix the magnification of the distant scene to four times, which is already preliminary to meet the requirements of the battlefield. ”

"An optical sight has at least three optical lens groups, one objective lens group, one correction tube group and eyepiece group, and possibly other lens groups. The objective lens group is responsible for light collection, so the larger the objective, the brighter the sight in the scope, and the eyepiece group is responsible for switching these rays back to parallel rays, so that the eye can focus and create the maximum field of view; The calibration tube group corrects the image of the objective lens from upside down and left and right to the correct direction, and is responsible for adjusting the magnification. The position of the sight line can be in the first focusing plane in front of the correction lens group, or the second focusing plane after it, and the wind deviation adjustment button and height adjustment button are used to control the left, right, height, front and rear positions of the correction mirror tube group. ”

"There may be more than nine elements in an advanced scope, and with the appropriate coating, the light transmittance can exceed 95%. However, even if the light transmittance is not so high, the brightness in the field of view may still be higher than the brightness of the visual field of the naked eye, because the light collection area of the general objective lens is larger than the light collection area of the eye. This is how the scope works and how to use it, but it's not that simple. ”

After listening to Chen Er's words, Wang Yong and Li Jun were stunned, they had heard of these theories for the first time, and many terms still hadn't been understood, but since Chen Er said so, I think he had a way to solve these problems. Li Jun simply said: "Second brother, it's useless for you to talk to us about this now, I think you should just say what the two of us can do, just listen to your orders." ”

Chen Eryi thought about it, just saying this to them is estimated to be just talking on paper, or they have to wait until they finish the scope, and when the time comes, they may be more likely to accept it when they go to the shooting range to demonstrate. Thinking of this, Chen Er and them carefully removed the lenses on the telescope one by one, but the lenses of the telescope were larger than the scope he designed, and there was no way to fit them for a while.

Li Jun suddenly said: "Second brother, otherwise, wouldn't it be okay for us to use the machine tool to grind this lens a circle." Chen Er refused without hesitation: "No, these lenses are specially treated, if they are processed on the machine tool, there may be small cracks, then the previous work will be wasted, I think I should make a new sight from the new lens." ”

Wang Yong also said: "Chen Er, is that necessary, I think Li Jun's idea can also work, 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 pays attention to a precision, you can ensure that the lenses that have been polished by you are exactly the same, it is absolutely impossible to do it manually." ”

As soon as Chen Er said this, Wang Yong and Li Jun were both wilted, they really didn't understand this, so they could only listen to Chen Er. Chen Er found some new raw materials again, and began to work on the machine tool, this time he designed the scope with the size of the lens, although it was a little worse in terms of aesthetics, but it would not affect the practicality at all. And Chen Er deliberately added a dust cover to the scope this time, which was also a problem that he had ignored before, and he suddenly thought of it when he saw the dust cover of the telescope.

In the expectation of Li Jun and Wang Yong, Chen Er was busy for a whole afternoon, and as soon as the machine stopped, Li Jun and Wang Yong immediately walked over and asked in unison: "How is it, has it succeeded?" Chen Er wiped his sweat and said, "What do you say, this afternoon's time can't be in vain." As he spoke, he picked up the completed scope on the table and handed it to Li Jun.

Li Jun hurriedly put it in front of his eyes and looked at it, and said while watching: "Second brother, don't say it, this thing is really good, you can see things in the distance quite clearly, I think this is not worse than that telescope at all." Wang Yong also hurriedly took it and looked at it, and the two of them were amazed.

Chen Er has nothing but some tiredness, not to mention that this scope is expected to have the function of a telescope, which is nothing, and its real use can only be truly reflected when combined with this sniper rifle. When Li Jun and Wang Yong had seen enough, Chen Ercai carefully installed the scope on the upper part of the sniper rifle, and a complete Type 85 sniper rifle was finally presented in front of them.

Chen Er said: "How about it, this is a sniper rifle, looking for a target through an optical scope, and then locking on to 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 guò scope, and said: "Second brother, is it that I can kill the target as long as I use the guò scope to determine the target and pull the trigger, otherwise let's go to the shooting range to test it first." ”

Chen Er took the sniper rifle and said, "That's fine, by the way, I will also make a basic correction to this gun." "Although the sniper rifle has been made, the school gun still needs to be completed by firing live ammunition. Taking the twenty bullets that had been prepared a long time ago, the three of them headed for the shooting range. Li Jun took the initiative to hold a sniper rifle, and it was time for him to show his skills later, and he was full of enthusiasm for shooting.

Soon arrived at the shooting range, Chen Er said to Li Jun while pressing the bullet into the magazine: "The recoil of this sniper rifle is a little larger than that of ordinary firearms, and when you shoot for a while, you have to use your shoulder against the butt to avoid shoulder injury." Li Jun said with a smile: "Knowing the second brother, don't worry, I won't joke with my body." Pressing the magazine, Li Jun just walked towards the firing position.

I saw that he was lying there quickly, and after setting up the gun, he pulled the bolt hard. Then one eye looked at the target in the distance, and sure enough, the target was a lot clearer all of a sudden, and after Li Jun aimed at the red heart, he adjusted his breathing and pulled the trigger. He only felt a strong force coming at his shoulder, but fortunately he was able to withstand the butt of the gun, or he might have suffered a small injury.

With the experience of the first shot, Li Jun fired four more shots, and there were not many bullets, so he could only save a little. After putting away the gun, Li Jun took his own target, and sure enough, although there was a slight deviation, there were forty-five or six rings in the five guns, which was definitely a breakthrough in any of her previous achievements, not to mention that the firearms had not been calibrated.

Next is Wang Yong, who also fired five shots, and his results are similar to Li Jun's, so he is naturally quite satisfied with this sniper rifle. Usually he doesn't have many opportunities to shoot, not to mention that he also knows his level, if it weren't for the sniper rifle he used, it would be good to be able to shoot thirty rings. The last to appear was Chen Er, who once again pressed the magazine and then lay on the firing position.

Because Chen Er had already seen Li Jun and Wang Yong's targets just now, the impact point of the bullet was obviously a little down, and besides, this was only a 100-meter target, and there was no wind and direction in the cave. Soon, Chen Er completed the calibration of the firearm, and pulled the red heart of the bolt at the target to pull the trigger. Chen Ertong's scope can clearly see that there is a small hole in the middle of the red heart.

Next, Chen Er fired four shots in a row, but there was still only a small hole in the target, and the five shots were all in one place, and it seemed that his calibration of this sniper rifle was relatively successful. After Chen Er retrieved the target, Li Jun and Wang Yong didn't know what to say when they looked at the handle, these five guns were one hole, and there were not a few such sharpshooters in the army.

Chen Er said with a smile: "Well, you know the benefits of a sniper rifle, I am not a soldier who has undergone strict training, but I have mastered the essentials of using a sniper rifle." This target shooting score is definitely comparable to anyone, and this is the power of the sniper rifle. ”
