Chapter 680: Hand-held machine gun

Under certain initial conditions and certain external moments, the gyro will continuously rotate around another fixed axis while rotating continuously. This is the precession of the gyro, also known as the gyro effect. (gyroscopiceffect). The spinning top is a common phenomenon in daily life. One example is the spinning top that many people have played when they were young.

Such a reversal effect has already been discovered in Qin's domestic scientific experiments. And the name is called the spin effect. And made the earliest gyroscope based on this principle. The appearance of the gyroscope will benefit Qin Guo's spaceflight, and it will be a huge help in ballistic missiles.

However, this technology is currently undergoing gradual experiments, and it will take a long time for large-scale applications. But this requires a lot of time, financial resources, and manpower to research. It also needs a lot of market demand to stimulate. However, Qin State has such a long-term utilitarianism, and it is difficult for things that are not useful for a short time to have a market for survival. This pragmatic approach is sometimes undesirable. What Shang Wen is worrying about is Qin's educational methods and scientific research methods. If you can't concentrate on research. Qin will be overtaken by other countries in the field of science and technology sooner or later.

However, a new weapon has proved Shang Wen's idea. Qin currently has two types of bullets, rifle bullets and pistol bullets. Because of Wenyang Arsenal, Qin's intermediate bullets were suppressed.

With the emergence of machine guns such as semi-automatic and automatic weapons. Firearms makers began to turn their attention to the automation of firearms. But soon the gunners discovered a problem. That is, using the huge recoil of the rifle bullet will make the user's muzzle jump up. Resulting in reduced accuracy. The solution is to increase the gun body. Or use other methods. But there is still a lack of such a balance between firearms and bullets.

Just when the gunners paid attention to researching rifles that use rifle bullets, another weapon came out. The submachine gun that uses the .40 pistol ammunition came out. This submachine gun was invented by an unknown gun repairman. The gun is modified from an old rifle, because there are many such guns in repairing rifles. The repairman believes that instead of spending a lot of attention to research and improve firearms. It is better to use a less powerful pistol. After the use of pistol bullets, this problem is reduced a lot.

And the rate of fire has increased greatly. The rate of fire reached an astonishing four hundred rounds per minute. But usually no one does this. The bolt action uses a free style bolt action. The barrel is an air-cooled tube made by cutting. Use straight 32-round magazines. The magazine is turned in from the left. The unknown gun repairman invented a very remarkable weapon for himself, so he was very excited to show it to the military. But the military shook his head. Mainly, his combat distance is too close. Only about one hundred and twenty steps. If a longer bullet is used, this distance may be increased. But this distance is too risky, and the accuracy of shooting still has a big problem. The muzzle will jump up when the bullet is fired at a faster speed. This is one of the shortcomings that all submachine guns are difficult to overcome. This kind of jump up leads to low accuracy of the submachine gun. Especially in the case of continuous shooting.

"This quick-fire short special rifle is really useless. It wastes bullets extremely. The rate of fire is very fast. But the power is small. And the rate of fire is short. You know, our opponent Huns can also shoot a hundred. Multi-step bows and arrows. If used against the six-nation armies, the opponent's rifle can shoot more than two hundred steps, this weapon will not reach the opponent at this time. This weapon is really too bad. Junk-level weapon "A Qin army officer commented on this weapon. Obviously, Qin Jun has not yet prepared for the equipment and various foundations of the submachine gun. You know, at this time, the Qin Army is still not equipped with a large number of mechanized armored vehicles. The target is still fighting in the wilderness. Shooting distance has always been a very important reference standard. Moreover, the targets of the Qin Army’s combat were the grassland nomads who had the same high mobility. These nomads were best at bows and arrows, and the 120-step combat distance of the submachine gun obviously did not conform to Qin’s idea of ​​avoiding their opponent’s bow and arrows . So this weapon was eliminated, and it did not attract much attention. In this way, Qin State once again passed by with the submachine gun.

However, Li's Arsenal was very interested in this weapon because they smuggled a large number of rapid-fire pistols. Their pistol is a crankshaft pistol, and the pistol used is a .40 pistol. This pistol has a long bullet, and the pistol is equipped with a wooden butt, and the barrel is slender, so that its shooting distance can reach more than two hundred steps. However, this pistol is expensive because of its peculiar structure. In the fight for the pistol order for the Eastern Front, it often loses to the simple 17th division point 50 pistol of Wenyang Arsenal. And Qi State does not imitate this pistol. As a result, the Li Armory lost a large part of the order. To make up for this phenomenon. Li's arsenal took another path. Looking for a weapon that fires faster than the Type 17 pistol, in the weapon test. Li You discovered this weapon that Qin Jun considers junk, and bought the patent for the gun at a price of twenty gold. Then it switched to producing one hundred for the Qi army on the Eastern Front for free.

This is the secret weapon of the Qi army, the submachine gun. The Qi army has a large number of commandos, and more and more commandos are beginning to complain about the shortcomings of pistols. When fighting in a small trench, the most important thing is to suppress the opponent's firepower. Facing the Yan army who uses rifles, the Qi army has the upper hand, but if it uses revolver guns, this loss will be great. The Qi army commando team needs to pull the trigger continuously to fire continuously, but even this cannot suppress the opponent's machine gun shooting.

Unfortunately, even the 13-round magazine for the pistol is still not enough. If fighting in a narrower area, the fire suppression of the pistol appears very weak. At this time, the appearance of the submachine gun made Qi Jun see an exciting weapon that made them novel.

"This weapon has a faster rate of fire than Yanren's revolver. Normally, it only takes a blink of an eye to light up thirty-two bullets in a magazine. This mood is indescribable. \"The commandos who use this submachine gun call it "small machine gun." Or "hand machine gun." The emergence of submachine guns largely solved the problem of insufficient firepower of the Qi army.
