Chapter 325: The Gun Must Have Grenades

He pointed at the receiver cover. It wasn't that he had any problem with the shaking receiver cover. Unlike his previous life, this time he had no problem with it at all.

This thing is just a dust cover. In fact, the gun can still be fired even if it is removed. The dissatisfaction in the previous life came from the difficulty in adding accessories to this thing. But now we are so poor that we don’t have so many accessories to install. It’s good enough that the gun itself can be repaired.

What if you want to install accessories if you have money?
Believe in the wisdom of future generations!
It's not impossible to get a new one when the time comes. That's a matter of decades later, and it can be said to be an issue for the next generation of rifles. There's not much point in thinking about it now.

At this time, he pointed to the receiver cover because of another problem.

"Professor Liu, judging from the current overall architecture and technical route, the bolt carrier of this gun may be very long. You see, from the current point of view, the receiver cover is already this long, which may bring a problem."

Professor Liu took it very seriously: "Director Gao, you say!"

"The bolt carrier will occupy the total length of the gun, shortening the aiming baseline and affecting the aiming accuracy."

The aiming baseline, for iron sights, is the distance from the rear sight to the front sight. Within the allowable range, the longer this distance is, the better the aiming accuracy.

To put it simply, even if the gun can shoot accurately, it is not good if the aim is not accurate.

The gun in my previous life was like this. The long bolt carrier at the rear and the long grenade adapter and flash suppressor at the front each took up a portion of the gun's length, resulting in a not-so-ideal aiming baseline length.

And the most unfair thing is that the adapter was of no use later, because our first generation of rifle grenades was not good, and the second generation was bumpy, so it was basically not used.

Professor Liu took a look and nodded, saying, "You make sense. We will pay attention to this when we start the detailed design and try to take both into account."

Being able to achieve this step is enough. In fact, the aiming baseline is not a big problem. It is good to improve it as much as possible.

He pointed at the muzzle device of the conceptual gun and asked: "Are you ready to load the grenade here?"

What can I say about rifle grenades? After rifle-mounted grenade launchers and disposable rocket launchers were installed in large quantities, this thing no longer had much significance. Moreover, among these types of team attack firepower, rifle grenades seem to be the most practical, but in fact their effectiveness is the worst. Later, major powers did not pay much attention to them.

The biggest problem with this thing is that it has great power but can't hit far, and it has little power when it can hit far. No matter how far or how big or small, it can't hit accurately and its ballistic performance is extremely poor.

There is no need to talk about technical issues. From the perspective of energy conservation, we know that the launch energy comes from the small amount of propellant that was originally used to launch a bullet of a few grams to a distance of hundreds to thousands of meters. However, the grenade shell weighs hundreds of kilograms, and it only relies on this small amount of propellant to launch it hundreds or even thousands of meters away. If its comprehensive ballistic performance can be good, then it is a miracle.

This is a bit similar to Gao Zhendong's previous life. The "regional" air defense missile Barak-8 imported by Zang San relied entirely on wandering. It was said to have a range of 70km, but in fact, at that range it could only hit targets without maneuverability such as transport aircraft. Military fans jokingly called it a "wandering bomb."

As for conflicts between some small countries or tribes, it is still very common. This is normal. They are lucky to get weapons and ammunition. Why do they need bicycles? This is not a joke. For them, it is not uncommon for the conflicting parties to sit on both sides of the battle line with empty guns and stare at each other for days or even more because they have run out of ammunition.

However, at this moment, it is not easy to blame or cancel anything. At this moment, at least in terms of the existing team's firepower, on paper, the rifle grenade is still good. It can be used to attack infantry and temporarily attack armored vehicles. It is better to have it than not.

So he just put forward his own opinion: "Professor Liu, if this rifle grenade is still being developed, I have a suggestion - you must not use the blank cartridge firing method, you must use a design such as a live ammunition catcher!"

Gao Zhendong's two "certain"s made Professor Liu pay attention. He frowned and said, "We are indeed preparing to use blank cartridges now. It is the simplest and most convenient."

Gao Zhendong said: "But in this way, the combat preparation for using rifle grenades will be very cumbersome and troublesome. Unloading magazines, ejecting bullets, loading blanks, plus the preparation for the launch of the rifle grenade itself, this has a huge impact on the soldiers on the battlefield where every second counts. With all this, many opportunities for war are lost in a flash."

This is where the perspectives of designers and users differ.

The designer's idea is that these things are not that troublesome, just spend some time and it should be fine.

The user's thinking is that the problem is so serious that you'd better not cause me any trouble.

Moreover, the rifle grenade itself often needs to be opened or installed with shooting accessories.

For example, the sight. In many video materials of rifle grenade shooting, there is a long thing standing up on the gun body or the tail of the rifle grenade. That is the thing. Because the trajectory of the rifle grenade is very different from that of the bullet, its sight generally needs to be installed separately.

Professor Liu thought for a while and nodded: "What you said makes sense. I will solemnly explain this situation to the comrades in charge of the grenade launchers."

Gao Zhendong did not just raise questions without talking about solutions. He also gave a few suggestions: "If the live ammunition catcher has difficulties, there is another way, the through-type. Do not capture the warhead, let it pass directly through the middle of the rifle grenade, and rely on friction to obtain launching energy during the passage. This is also a way. By the way, it is best to make the aiming accessories on the rifle grenade and make it foldable." This method also has flaws, such as incomplete energy transfer and low controllability, but in Gao Zhendong's previous life, he also invested in practical rifle grenade launching technology.

As for the principle of side-projectile ejection, Gao Zhendong did not mention it. The aim was already not very accurate to begin with, and if a high-speed warhead was thrown sideways, what would be the result? Anyone who has studied the law of conservation of momentum would understand.

Professor Liu's eyes widened immediately: "Director Gao, your thinking is really unconventional. You can always solve problems from angles that ordinary people can't think of. This idea is very interesting."

While praising him, he wrote furiously, feeling very happy. With this piece of paper, he could easily get three meals out of Lao Luo! Who is Lao Luo? He is the one who deals with grenade launchers in their school.

The students around him were also stunned by his fantastic idea. Is this how a big boss thinks? I'm so sorry.

Gao Zhendong decided to go all out. I'll give you another rifle grenade. I believe that with this, plus the disposable tube, after trying it out, rifle grenades and the like will become a piece of cake.

Under current conditions, the grenade hanging from a gun relies on pure creativity and is not technically difficult.

"Professor Liu, I have a new idea, which is to improve the firepower of blasting within the team. Are you interested?" Gao Zhendong looked at Professor Liu with a smile. I don't believe you won't take the bait.

Professor Liu was shocked. Eh? There is also this unexpected gain? Director Gao's ideas have always been necessary and feasible. Even if they cannot be used due to environmental conditions, they are definitely good things.

He waved his hand, signaling to the students, "Listen carefully, Director Gao is about to give a speech."

He turned around, grabbed a pen, and turned to a new page in his notebook: "Director Gao, this question is useless. I am interested in any of your ideas. I am all ears. I am all ears."

Gao Zhendong also picked up a pen and said, "Let's make a gun-mounted grenade launcher."

"Grenade launcher mounted on a gun?" Never heard of it.

"Yes, we make a suitable grenade, the caliber is 30~40mm, and make it into a complete bullet-like shell. Then we make a simple launch tube and hang it under the gun, right here!"

As he spoke, he pointed the pen to the position below the barrel and in front of the magazine.

"Huh?" Professor Liu looked at where Gao Zhendong's pen tip was pointing, and as he looked and thought, the more he thought about it, the more he felt that this position was wonderful.

It is large enough to hold a launch tube without affecting the carrying length of the gun or the thickness of the gun. It has a certain impact on the center of gravity of the gun but it is not serious.

From the organizational point of view, this thing is originally an additional hanging. Only a few firepower operators in a squad need to hang it. It does not destroy the overall firepower configuration of the squad. If it is available, it can be hung up. If not, it will not affect the gun itself. This respect is similar to the rifle grenade, but the firepower reaction speed is much stronger than the rifle grenade.

The students also discussed enthusiastically.

"This is interesting. Except for being a little less powerful, it's not worse than a rifle grenade, and its ballistic performance is worlds apart."

"That's right. If we design the ammunition specifically for this purpose, we can definitely optimize the trajectory."

"If designed properly, it can be quite powerful against personnel. The caliber of a rifle grenade is not much larger than this."

"Anti-armor is also possible. It has a 30~40mm caliber and uses a shaped-charge armor-piercing warhead. It can hit light armor without any problems, and it can also take into account killing."

This classmate must be a good student. Shaped charge armor-piercing missile is slightly different from shaped charge armor-piercing missile. It is more similar to a self-forged fragmentation warhead. It is more suitable for anti-armor and anti-personnel missiles, and has a small requirement for the length of the projectile body.

While listening to the students' discussion, I thought to myself, Professor Liu's expression was becoming more and more happy. Director Gao made good suggestions, and the students learned well!

"Director Gao, once this is done, I will go back and make this thing an accessory for the gun family and start a project!"

The good thing about having a large systematic project is that gun-mounted grenades can be simply used as an accessory system and it can be set up. The process is simple and the funding is relatively secure. Even if there is no new funding, it is enough to squeeze a little here and there from the large project.

Especially since the rifle-mounted grenade itself is a relatively simple thing, and if they don't spend a lot of time optimizing the grenade, they can make it very quickly.
