Qin Guan frowned. He looked at the person who stood up in front of him. He was an old man. This old comrade was also a veteran who was struggling on the light weapons front. He also had a handy weapon design. For example, Type 67 general machine gun.

At the beginning, the weapons of the Han army were definitely from the Wan Guo brand, which was very complex and terrifying.

Among other things, there are more than ten kinds of machine guns, Hans State’s mg34mg42mg13.mg15. There are also ZB26/30 in the Hatchikes series of the chicken country, and even Taisho eleven crooked handles, 96-style crutches, and so on.

Later, the army gradually changed its equipment, leaving only the 53 and 57, but the domestic development of a general-purpose machine gun was serious.

Therefore, China decided to develop a general-purpose machine gun for model unification. Everyone decided to learn from the structural scheme of foreign excellent machine guns. In this way, it is a hodgepodge design based on the strengths of various countries.

Ordinarily, it should be a good weapon, but after the 67-type machine gun was equipped with troops, a lot of problems were exposed, what kind of jammed bullets were fired in the empty chamber, there were damage to the gun, the frame of the gun, etc. In that era During the peak period of the political movement, these are all understandable.

As a machine gun, it will inevitably jam once after it has fired a thousand rounds. This is only under normal circumstances, there is such a serious jamming failure rate.

If in the harsh environment with wind and sand, the reliability will drop sharply, even after hundreds of bullets are fired continuously, it will jam, which often leads to spontaneous combustion of the bullets in the bore and dangerous explosion failure outside the bore.

It can be said that this is an extremely unreliable weapon, so this machine gun has also been rated as one of the worst general-purpose machine guns of the 20th century.

This may be a slanderous element, but after the start of the Monkey Kingdom battle, many troops urgently withdrew the unreliable Type 67 machine guns and restored the old Type 53 and Type 57 machine guns. This can explain the problem.

Now, this old comrade is a veteran of the light weapons development industry and a supporter of the 5.8mm bullet project. Facing the equipment Qin Guan suddenly took out, he held a negative attitude.

Even if it can be blocked, what's the use?

Those who use it also suffer internal injuries!

Qin Guan listened to his words with a smile on his face: "It seems that in order to convince everyone, we still have to try it ourselves."

After speaking, Qin Guan picked up this bulletproof vest and began to wear it on his body.

"Ms. Qin, let me come." Xiucai said, he must take it over. Xiucai cares about Qin Guan the most. At this time, you can't let Qin Guan take risks.

"If you come, then I will shoot you. Do you have confidence?" Qin Guan said, "Even if you have confidence, I don't have confidence. It's better for you to shoot me, I don't worry."

What Qin Guan said was very light.

If a talented person wants to wear it, who will shoot? Qin Guan? Qin Guan has never played with a gun a few times. What should he do if he misses the shot and hits Xiucai on the head?

It's still a talented shot who is accurate.

In fact, the scholar was circumvented inside. In fact, in addition to the scholar, there are Xiang Jing, Major Yang, and the Vulture Special Forces. Anyone who can pull out can complete the shooting mission. Their accuracy is absolutely 100%.

But now, with what Qin Guan said, the scholar had a fixed mindset, thinking it was the matter of these two people.

The Xiu Cai was taken aback, Qin Guan was already wearing it, and said to Xiu Cai: "This time, let's change the AK74. In order to increase its power, the distance is reduced to 100 meters. No, 50 meters. You shoot me."

In Han, there is the skill of practicing darts, which is to use people as targets. Moreover, the darts have to blindfold their eyes. If the darts are nothing, there are also throwing axes. In short, use the words of the oil seller. In terms of no one, only hands are familiar.

Now, for his own safety, Qin Guan has lowered it to 50 meters and allowed the scholar to shoot himself. Moreover, when Qin Guan was a target, he also put on the bulletproof helmet he brought with him, in case the scholar missed the shot. What?

"President Qin, there is no need for you to take risks. Let's change individuals." The leader of the logistics equipment department was also anxious. Even the old expert who held a negative attitude just now quickly said: "Yes, President Qin, let's change. personal."

"I have confidence, it's absolutely fine, besides, if something happens, ordinary people are also a life, and they cannot be allowed to take risks. You back, come on, scholars, fire!"

Xiucai was fifty meters away and picked up the AK74.

If you are a layman, you can’t see the difference between AK74 and AKM at all. The two are almost the same. In fact, they have the same principle. There are 50% of the parts that can be used in common, just caliber. That's the difference.

The previous 7.62mm bullets have great power and long distance, but they have low accuracy and large recoil. However, this small-caliber rifle is just the opposite. It has low recoil and high rate of fire. Although it is small, it will roll after entering the human body. The actual lethality may be greater.

Now, shooting at Qin Guan?

The talented person will not have too much psychological burden, because the talented person knows that if the 5.56mm projectile just doesn't penetrate, the 5.45mm bullet will not penetrate. Its power is even smaller, even at a distance of 50 meters. on!

"Da!" The Xiucai breathed calmly, then, pulling the trigger, the 5.45mm bullet, rotating in the barrel, flew out, for a distance of 50 meters, for it, it only took less than 0.1 In seconds, almost when Qin saw the fire from the muzzle, the bullet had already hit Qin Guan's chest.

The bullet lightly pierced the outer layer of cloth and hit the ceramic plate.

If you slow down the camera, you can see that at this time, the 5.45mm small-caliber rifle bullet, the warhead has been broken during the impact, and turned into small pieces. These small pieces give the area of ​​action of the warhead. Instead, it increased.

In the case of the same impact force, the larger the area, the smaller the pressure.

Then, cracks began to appear on the ceramic surface in the collision zone and extended from the collision zone.

This effect is three-dimensional. In addition to extending to the outside, it is still advancing along the compression wave front in the collision zone, deep into the interior of the ceramic, and the ceramic inside also begins to break, and countless powders are generated and scattered towards the outside. Otherwise, that The hole will not appear.

At this time, cracks began to appear on the back of the ceramic.

Subsequently, the fiber layer behind the backplane also began to be impacted. The fibers are distributed across. The impact energy will be dispersed at these intersections. At the same time, the separation and offset of these fibers are constantly absorbed The energy of these shocks.

When the bullet has not penetrated, it has stopped.

Of course, this was just the bullet stopping. For Qin Guan, at this moment, Qin Guan suddenly yelled, and then fell backward!

"Ms. Qin!" Xiucai dropped the gun and ran over quickly. Isn't something going wrong?
