This chapter is still written for friends who love weapons, if you are not a weapon lover, then too much technical discussion in this chapter may bore you, please pay attention when subscribing, thank you.

Now, not only has the appearance of the machine gun changed, but its weight has also been reduced to the delight of the machine gunner, and as for its lethality, it has not only not decreased, but has increased considerably.

The new machine gun was made of extensive stamping, spot welding, and riveting, and although it was not a new thing today, it was definitely an innovation at the time. Speaking of this method of production, it is impossible not to mention the grandfather of the world universal machine gun - the German MG-42 universal machine gun.

This is an extremely excellent weapon, and even to this day, it can still be seen in the armies of some countries, and people cannot but admire its "old age and strength".

In World War II, it made a sound similar to "tearing oilcloth" due to its high rate of fire, which reached 1200 per minute. It was called "the nightmare of the infantry" and "the bullet thrower" by the Allied soldiers who were hit by it.

Of course, as a weapon of World War II, it also has the disadvantages of a more complex structure, a slightly larger weight, and excessive recoil when firing. Therefore, as a weapon modeled on the MG42, it is intended for long-term use and is not intended to be redesigned and manufactured. In the most designed and manufactured, in terms of performance, it has been ruthlessly reduced.

When this machine gun was designed, experimented, and produced in Batavia, it not only had excellent light weapons experts participate in the design, but also incorporated the technology of modern light weapons that Tang Yunyang knew, so that its performance reached the highest level of machine guns before World War II.

First of all, it was a general-purpose machine gun, a light machine gun when using a bipod and a heavy machine gun when using a tripod, which alone broke through the design concept of machine guns at the time. At the same time, in order to improve the heat dissipation of the barrel, a layer of aluminum alloy outer tube with heat dissipation patterns is attached to the outer layer of the barrel, and the outermost layer is still a square sheath that protects the barrel.

As for the biggest advantage of the MG-42, that is, the gun's ammunition feeding system is extremely excellent, and such a high rate of fire can still smoothly deliver ammunition, and the M60 general-purpose machine gun of the US military later was modeled on this mechanism. This time, nature will make no major changes except for small changes.

Due to the use of aluminum alloy and fiberglass telescopic butt for the butt, guard pipe and other parts, the weight of the whole gun is controlled at about 8 kg. The new long-barreled muzzle device has the effect of extinguishing and retiring flames, and also effectively solves the problem of excessive muzzle flame when this gun shoots at night.

This gun was used by Mike Brown, who was in charge of organizing the research work in Batavia. Lang, named the "1917 Wolf General Purpose Machine Gun", also passed the addiction of naming new weapons.

The "L Universal Machine Gun" uses 7.62 mm ammunition, i.e. a 150-round saddle feeder can be used to accompany the infantry forward. It is also possible to use a self-unloading chain of 250 or 500 rounds to feed ammunition, and the basic data is a rate of fire of 1000~.

Machine guns use exactly the same cartridges as rifles throughout the weapon system, and are a unique type of bullet, which will be explained in more detail later.

The other "big guy" in the infantry squad is the soldiers, they are the symbol of the safety of the infantry squad, and they are not likely to be killed by machine gun fire if they are in the infantry squad, so their importance naturally does not need to be mentioned.

Sniper rifles, also weapons of new design and manufacture.

This rifle was concentrated in Mauser (Germany), Mosin Nagant (Russian), Lee Brown. The advantages that can be found in Enfield, M1930 Springfield rifles, Japanese Type 38 rifles. It is designed and manufactured in a way that is somewhat similar to the means used by the United States to design the P51 Mustang fighter - that is, to concentrate the advantages of all products of the same type.

If you look at it from a modern point of view, the appearance of this new infantry sniper rifle is somewhat similar to the M-24 sniper rifle in the United States today, although due to the difference in manufacturing capabilities, their accuracy and attack range are not above the same level.

In addition, the advantages of this sniper rifle for the rifles of various countries are also inherited separately.

For example, the bolt of the Japanese rifle is extremely strong when it is locked, and there has never been an explosion incident, and at most the barrel bursts, you can see how strong the bolt is. Plus, the recoil of the Japanese rifle was quite small. There are 4 right-handed rifling wires inside the barrel, and in order to pursue shooting accuracy, the rifling lead is determined, so the advantages of the warhead fired by the "38 big cover" are also inherited, and because it belongs to the long barrel, there is almost no muzzle flame when firing.

This sniper rifle also adopted Lee. The Enfield bolt has the advantage of being smoother and smoother than the Mauser when fired. The good coordination between the barrel and handguard is one of the main reasons for Mosin Nagant's high accuracy.

As for its super-modern characteristics, it is naturally even more staggering.

The barrel of this "poisonous bee" D-1 sniper rifle uses a stainless steel heavy-duty extended barrel, and the body of the gun is made of a large number of fiberglass parts. The gun adopts a rotary pull-back bolt, with good locking stability, simple structure, and close cooperation between the gun body and the bolt. The bullets used are specially designed and manufactured with precision, so they are more accurate.

The "Vistrous Bee D-1" is equipped with a detachable bipod, an adjustable stock, and an adjustable gills plate for a 10x magnification scope. It's just that relatively speaking, snipers in infantry squads use a larger field of view of scopes, and they use 5x scopes, and use ordinary 7.62mm rifle cartridges.

After talking about sniper rifles and machine guns, the following is the protagonist of the change of gun, the automatic rifle. But before talking about this weapon, we have to mention that Tang Yunyang used the conditions of the Air Force to be stationed in Shanxi to dig up the treasure from the Hanyang Arsenal in Yan Xishan.

This baby is one, his name is Liu Qingen (1869-1929), the word Guochen, a native of Deyang, Sichuan. After graduating from Guangdong Naval Academy, he was assigned to Hubei Gun Factory for internship, and was later sent to Japan by Hubei Province to study machinery and gun production, and graduated from Tokyo Imperial University.

Speaking of him, there is still a glorious history, if history has not changed, then a few years later he will design a Chinese semi-automatic rifle and go to the United States to participate in the "draft" of the US military rifle. Of course, the design of the M-2 is nothing to do with him now, and his role will be reflected in the future.

Since the M-1 Eagle is so popular with infantrymen for its firepower density, this rifle is designed entirely on the former. If you can't look like the new gun, then think about what the M4A2 looks like, of course, the essence is still different.

In fact, there are quite a few similarities between these two equally excellent small arms, especially the small grip and the position of the magazine. Imagine how different a Mauser pistol is from the M4A2 in terms of appearance, if you add a Mauser with a straight butt and a handguard on the front.

This only illustrates the fact that the overall layout of the Mauser pistol, designed as a shoulder-fired weapon, is extremely reasonable, especially adapted to the trend of the development of modern light weapons.

The layout of the M-2 assault rifle is the same as that of the M1 Eagle short assault rifle, with Picatinny rails, a 1.5x magnification scope, a telescopic stock, an aluminum alloy magazine, and a chrome-plated barrel. But one thing that must be mentioned is limited to the level of processing, the whole gun weighs 3.5 kg.

The gun uses a new 7.62 mm round with the ability to fire three bursts, and can also be attached with a rocket-propelled 35 mm grenade with a bullet catcher and a straight trajectory.

With the exception of the assault rifle, which was formally designed and manufactured, the 1911 is undoubtedly the longest pistol in service in the world. However, when used as an Oriental, its excessive recoil made it difficult to control the shot.

Therefore, at this time it was completely improved into the M1911A1, 9 mm pistol. Among them, the pistol cartridge has also been modified, using the means of putting the bullet lead core behind the British design and stopping the 2~3 mm space at the tip of the bullet.

The advantage of this is that after the bullet enters the human body, it will be very easy to roll and deform due to inertia, so that the stopping effect of the pistol bullet will not be reduced.

"Let's watch the first release together, please support genuine reading, and support the author's creation" Don't laugh and give birth to a group: 35761481; Mailbox:.

Correspondingly, the submachine gun was changed to a 9 mm bullet, and the redesigned bullet did not cause excessive changes in performance due to the change in caliber, on the contrary, due to the reduction of recoil, the shooting accuracy of the Situ submachine gun was improved.

The last thing to talk about is the current "1917 Wolf general-purpose machine gun" and the M-2 assault rifle, which are not strictly speaking 7.62mm bullets. It was nothing more than a 7.62mm bullet, a 4.5mm steel arrow held in place by a copper stock at its waist.

The advantage of this is that when the bullet is fired, the ring-shaped copper butt can complete the effect of air-sealing. At the same time, after the bullet is fired, it inherits the rotation transmitted by rifling. In this way, the ballistic trajectory of ordinary arrow-shaped projectiles is easy to lose stability and spread largely.

Relatively speaking, it is relatively difficult to make such guns and bullets than ordinary guns and bullets, but because China is a country that lacks copper, neither copper shells nor copper bullets are China's resources that can afford to fight a world-class war.

Relatively speaking, steel bullets and steel shells are, although the Chinese infantry did not like it so much, but had to accept things. Approximately, the 5.8mm bullets used by our 95 gun family have their own unspeakable hardships.

Although small-caliber ammunition saves resources, the world's most advanced processing capacity at this time could not make the ammunition needed for 74. Since this is the case, then it is necessary to take another path out.

After testing, the current 4.5 mm steel bullet has the rotation and impulse transmitted from the copper stock, making it no less powerful than the 7.62 mm bullet. Although there is a slight gap in terms of range, the accuracy is much stronger than that of the 7.62mm ordinary bullet.

This time, the main thing is to change the small arms, and at the same time, the rifle and machine gun, pistol and submachine gun ammunition are unified, which will be more beneficial for the supply of logistics.

At this point, the weapons for this reload have been introduced, so let's prepare for war, but there are still a few things to deal with before the war.
