Siheyuan starts from a better life

Chapter 270, Small Caliber Rifle
"Jiang, tell me if your tactical rail can be used on other firearms, such as our Type 56." Wang Hui, who was playing with the new gun, suddenly asked Jiang Yan.

"Yes, but depending on where you install it, the length of the guide rail should also be reduced."

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

While the two were chatting in full swing, the door of Jiang Yan's office was pushed open. Director Zhao Xinzhong and Secretary Zeng Ji came to Jiang Yan's office together.

"Where is the gun, let me see it quickly." As soon as he entered the office, Director Zhao Xinzhong yelled, and when he saw the gun in Jiang Yan's hand, he snatched it. When you see the "August [-]" class machine gun on the table, you walk up quickly and take this gun in your hand.

Both of them are cadres transferred from the army to civilians, and they are quite familiar with firearms. After asking a little bit, they fiddled with firearms skillfully there, especially Secretary Zeng Ji. I have to say that this educated person has a good head , After fiddling with the firearm in his hand for a while, he took it over and looked at the blueprint on Jiang Yan's desk. After looking at it for a while, he took the blueprint and came to Jiang Yan to ask various questions, and Jiang Yan was patient. After explaining it 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.

I have to say that the brain is indeed a good thing.

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

"Jiang Gong said that this is a tactical rail, on which small things such as optical sights, night vision goggles, tactical lights, laser pointers, small grips, bipods, strap rings and even grenade launchers can be installed."

Wang Hui explained the function of the tactical guide rail to Zhao Xinzhong, the director of the factory, and Zhao Xinzhong was taken aback for a while. For Zhao Xinzhong, what Wang Hui said was basically a new thing.

"Old Wang, I know this optical sight, but is this night vision device something used at night, and what is this laser pointer?"

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

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

"Xiao Jiang, if my guess is correct, this night vision device should be a night vision device, so what is this laser pointer?"

When Zhao Xinzhong asked about the night vision device and the laser pointer, Jiang Yan's heart skipped a beat.I screamed in my heart that it was not good. When I explained the guide rail to Wang Hui just now, my mouth was bald. Why did I say this.

Since the introduction of stimulated radiation in 1913 and the publication of a key paper in 1958, around 1960, many research groups in the world were actively competing to invent an effective laser. In 1960, American physicist Maiman invented It was only in 1956 that the first practically applicable laser was emitted, and it was nearly four years before the first laser was emitted.

This night vision device is easy to say, generally speaking, the night vision device refers to the external thermal imager, but it is generally believed that in 1940, Hans country developed the infrared transmission material, thus solving the material problem, and it was used in actual combat for the first time It was used by the M Army during the Battle of Okinawa in 1945.Its working principle is to actively use infrared headlights to search for photos. This thing was used by Citigroup's army in the anti-M and aid-C fear of our army's night combat capabilities. It is not troublesome to explain.

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

"Xiao Jiang, Xiao Jiang, what's the matter?" Seeing Jiang Yan in a daze, Zhao Xinzhong pushed him.

"Oh oh oh, I was a little dazed thinking about things just now. The factory manager, you are asking about this laser pointer! Strictly speaking, this thing has not been announced yet. I just saw a Citigroup when I was studying in SL. According to the report, they imagined that this thing could be used as an aiming device, and when Representative Wang Hui asked me about it, he said it directly.”

"Oh, let me tell you! This thing hasn't been invented yet, so I have to say, Xiao Jiang, you really think too far." Although Jiang Yan's explanation was a bit far-fetched, it was rounded up anyway. The three of them are now I put all my thoughts on this firearm, so I 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 installed on this gun." Secretary Zeng Ji next to him
Hearing Secretary Zeng Ji's words, Jiang Yan smiled wryly in his heart, this is pressing the gourd and lifting the ladle again!How could he have forgotten that the person in front of him had been to the Anti-M and Aid C battlefield and seen this thing before.

However, what he said is not wrong. Now is not the era of integrated circuits. All electronic equipment uses electronic tubes. If the night vision device is made with electronic tubes, the volume is estimated to be large, and it must be installed on the gun. unrealistic.

"This is also my thinking. I think that the night vision device is so big now, maybe later generations will shrink it. It is estimated that it will not be a problem to put it on the gun at that time."

Jiang Yan explained that his heart was also sweating, but thinking about it, that's all. Whoever said this, believe it or not, they can't arrest themselves because of this!

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

After listening to Jiang Yan's explanation, Secretary Zeng Ji didn't ask any more questions, but asked directly about the two "August 7.62" assault rifles: "I think the calibers of these two rifles should be different! This should be [-]mm. I can't see that."

"This is a 5.8mm caliber"

"5.8mm, this caliber is so small, why did you think of using this caliber?" After listening to Jiang Yan's words, Secretary Zeng Ji asked Jiang Yan curiously,

Hearing Secretary Zeng Ji's question, Jiang Yan thought for a while and said, "Secretary Zeng, have you noticed that from World War I to World War II, and then not long ago 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: "Large-caliber rifles have a long range and great power. It is especially suitable for the combat environment during World War I. Yes, it is trench warfare. The distance between the two sides is far away, and the emphasis is on precise shooting. "

"By World War II, some countries were still following the old path, such as Japan and other countries. But if you observe carefully, you will find that the combat distance in World War II was much shorter than that in World War I, and the individual firepower was much denser. Because they are equipped with a large number of semi-automatic rifles , submachine guns, etc. In this era, the combat distance of infantry squads is generally within 400 meters, sometimes tens of meters or even more than ten meters. The shortcomings of large-caliber rifles are fully exposed. Especially unnecessary damage caused by excess power, poor maneuverability (recoil force and other reasons)..."

"So I guessed that since the distance is so close, we have to invent firearms that are more suitable for close-range combat. After calculation, I found that the smaller the caliber, the higher the stability of the firearm. However, too small a caliber will not have enough lethality. , After calculation, I chose the caliber of 5.8mm, taking stability and lethality into consideration.”

For close combat, the small-caliber rifle is easier to control, with more intensive firepower and appropriate power.Moreover, incapacitating with a small caliber is actually better than killing with a large caliber. First, it can drag down the logistics, and second, it can affect the psychology of enemy fighters. In addition, under the same weight, it carries a large amount of ammunition, which can sustain combat. .
