"Jiang, do you think this tactical guide rail can be used on other firearms, such as our Type 56." Wang Hui, who was playing with a new gun, suddenly asked Jiang Yan.

"Yes, but depending on where you install it, the length of the rails will have to be reduced."

In the following time, Wang Hui raised various questions about this firearm, and Jiang Yan explained it very patiently.

At the stall where the two were chatting hotly, the door of Jiang Yan's office was pushed open, and Director Zhao Xinzhong and Secretary Zeng Ji came to Jiang Yan's office together.

"Where's the gun, let me see." As soon as he entered the office, Director Zhao Xinzhong shouted, and when he saw Jiang Yan's gun, he snatched it over, and Secretary Zeng Ji's hand was half a beat slower, but when he saw the "Bayi" type machine gun on the table, he walked up quickly and took this gun in his hand.

Both of them belong to the military-to-civilian cadres, and they are quite familiar with firearms, and after a little inquiry, they skillfully fiddled with firearms there, especially Secretary Zeng Ji, I have to say that this literate person has a good head, and after fiddling with the firearms in his hand for a while, he took the drawings on Jiang Yan's table and looked at them, and after looking at them for a while, he came to Jiang Yan with the drawings and began to ask various questions, and Jiang Yan patiently explained to him, after figuring out all the problems, He directly disassembled the gun in his hand into parts, and then assembled it according to the drawings.

It has to be said that the brain is indeed a good thing.

"Wang, what is this?" After fiddling for a while, Zhao Xinzhong pointed to the tactical guide rail above and asked Wang Hui, who was holding a gun next to him.

"Jiang Gong said that this is a tactical rail, on which you can install optical sights, night vision devices, tactical lights, laser designators, small grips, bipods, strap loops and even grenade launchers."

Wang Hui now learned and sold to Zhao Xinzhong to explain the role of this tactical guide rail, and bluffed Zhao Xinzhong for a moment, for Zhao Xinzhong, what Wang Hui said is basically a new thing.

"Lao Wang, I know this optical sight, but this night vision device is not something used at night, and this laser pointer, what is it?"

"This, this," Wang Hui didn't say a reason for a long time.

"I see that you also don't know much, I'd better go ask Xiao Jiang!" As soon as this sentence was spoken, Wang Hui's old face turned red, just now he was so happy that he didn't remember what these things were, so he followed Zhao Xinzhong to Jiang Yan.

"Xiao Jiang, if I guessed correctly about this night vision device, it should be a night vision device, so what is this laser pointer?"

Hearing Zhao Xinzhong ask about the night vision device and laser pointer, Jiang Yan's heart chuckled. I secretly screamed in my heart that it was not good, I was bald when I explained the guide rail to Wang Hui just now, how did I tell this thing.

Since the laser was proposed by stimulated radiation in 1913 and published in 1958, around 1960, many research groups in the world are actively competing to invent an effective laser, in 1960, the American physicist Mayman, invented the ruby laser, only to emit the first laser that can be used practically, and now it is only 1956, and there are nearly four years before the first laser is emitted.

Generally speaking, the night vision device refers to the external thermal imager, but it is generally believed that in 1940, Hans developed infrared transmission materials, which solved the material problem, and was first used in actual combat in 1945 in the Battle of Okinawa by the M Army. Its working principle is to actively use infrared headlights for searchlight, which is not troublesome to explain because Citigroup's army is afraid of our army's night combat ability in the anti-M aid C.

Jiang Yan's mind was running wildly, thinking about how to get this over.

"Xiao Jiang, Xiao Jiang, what's wrong" Seeing that Jiang Yan was stunned, Zhao Xinzhong pushed him.

"Oh oh oh, I was thinking about things a little bit distracted, the factory director, you are asking about this laser pointer! Strictly speaking, this thing has not yet been announced, I just read a report from Citigroup when I was studying abroad in SL, and they envisioned that this thing could be used as a target, and I was directly said to go up when Representative Wang Hui asked me before. ”

"Oh, I said! This thing hasn't been invented yet, I have to say, Xiao Jiang, you're really far away. Although Jiang Yan's explanation was a bit far-fetched, it was finally rounded, and the three of them were now thinking about this firearm, so they didn't think much about it.

"Xiao Jiang, you said this night vision device, I know, that thing is very big, it is used when camping, how can it be loaded on this gun." Secretary Zeng Ji next to him

Hearing Secretary Zeng Ji's words, Jiang Yan smiled bitterly in his heart, this is a gourd that is pressed and scooped again! How did he forget that the person in front of him had been to the battlefield of resisting M and aiding C and had seen this thing.

However, what he said is not wrong, it is not the era of integrated circuits, all electronic equipment uses electron tubes, and if the night vision device is made with an electron tube, the volume is estimated to be very large, and it is certainly unrealistic to install it on the gun.

"This is also what I think, I think that now this night vision device is so big, maybe the future generations will shrink him, and it is estimated that it will not be a problem to put it on the gun at that time."

Jiang Yan explained that he was also sweating in his heart, but thinking about it, that's it, who is the statement, believe it or not, they can't arrest themselves because of this!

However, this incident also sounded a wake-up call for Jiang Yan, and he should pay attention to what he says in the future.

After listening to Jiang Yan's explanation, Secretary Zeng Ji didn't ask much, but directly asked about the two "Bayi" assault rifles: "I think the caliber of these two rifles should be different!" This should be a 7.62 mm caliber, I can't see this. ”

"This is a 5.8mm diameter"

"5.8mm, this caliber is so small, why do you remember to use this caliber?" After listening to Jiang Yan's words, Secretary Zeng Ji asked Jiang Yan very curiously,

Hearing Secretary Zeng Ji's question, Jiang Yan thought about it and said: "Secretary Zeng, have you noticed that from World War I to World War II, and then to the recent War to Resist M and Aid C, the battle between the two armies is getting closer and closer. ”

Hearing Jiang Yan's question, Secretary Zeng Ji thought about it in his mind and said, "That's true. ”

After listening to Zeng Ji's answer, Jiang Yan continued to speak: "Large-caliber rifles have a long range and great power. It is especially in line with the combat environment of World War I, yes, trench warfare. The distance between the two sides is relatively long, and the emphasis is on accurate shooting. ”

"By the end of World War II, some countries were still following the same path, such as Japan and other countries. But if you look closely, you will see that the engagement distance in World War II was much closer than that of World War I, and the individual firepower was much more intensive. Because it is equipped with a large number of semi-automatic rifles, submachine guns, etc. In this era, the distance of engagement from infantry squads was generally within 400, sometimes tens or even tens of meters. The shortcomings of large-caliber rifles were exposed. In particular, unnecessary damage caused by excessive power, poor handling (recoil and other reasons) .......... ”

"So I guessed, since the distance is so close, we have to invent a firearm that is more suitable for close combat, after calculation, I found that it seems that the smaller the caliber, the higher the stability of the firearm, but too small caliber, the lethality is insufficient, after calculation, I chose the caliber of 5.8mm, taking into account stability and lethality."

In close combat, small-caliber rifles are easier to handle, more dense, and more powerful. Moreover, it is actually better to be disabled by a small caliber than to be killed by a large caliber, because it can drag down logistics, and secondly, it can affect the psychology of enemy fighters, and secondly, under the same weight, it carries a large amount of ammunition and can sustain operations.

It's been a bit busy to move these two days, don't blame it
