"Remove all guns with a total length of more than 800 mm!"

Guan Fei thought for a while and issued the first filtering command.

Swish!

With a light sound as a dubbing, the dense guns in front of me suddenly lost half of them.

Among them, the extremely subsequent version of the m16 basic model and its extended gun family were all like bubbles, bursting open and disappearing in front of you with the afterimage.

Only one assault type is left.

&》;The ak series, including the subsequent ones, is also half missing, leaving only the folding type and submachine gun model.

The gun light balls in other countries also broke one by one, leaving behind folding, submachine guns, and stockless designs.

The only ones that retain most of the light groups are the 95, 95-1, 95-2,03 types developed and produced by China, which are still relatively densely clustered into groups.

This is no wonder.

Westerners must have designed guns that are suitable for Western-type. As assault rifles used in wars, they will design full-size versions. Even if there are folding, telescopic butt stocks, etc., it is also to adapt to the use habits of Western-type soldiers in the jungle.

These folding, telescopic, and stockless automatic rifles consider that when fighting in mountains, jungles, and cities, they quickly emit guns without pursuing accuracy. Their uses are relatively limited and they cannot defeat the world with one gun. They also need to cooperate with other weapons, such as full stock automatic weapons to fight.

If China wants to equip weapons suitable for oriental human body shape, it can only refer to other people's design ideas, and it depends more on its own research and development. Therefore, it was designed from the beginning based on the Chinese figure, usage habits, load-bearing, and combat purposes, which naturally meets the conditions. Moreover, around a core gun type, the designed gun races are of many types and have a wider adaptability.

Guan Fei hesitated for a while, and took out a few foreign military guns from the light regiment and tried it.

Based on his years of practical experience in the army, these guns are indeed bigger, but because they use more composite materials, the gun body is not heavy. The human-machine functions are also considered well, and the hand feel is good when shooting.

The full power bullet has a greater recoil, and it is much better to use a 5.56 small-caliber bullet.

In a simulated shooting range, its accuracy is higher than that of the AK series and the military sub-district. However, in the folded form, since it cannot stand against the shoulders and waist well, it is basically impossible to carry out accurate attacks, so it can only conduct probabilistic shooting, relying on wide-distributed barrage attacks to try to suppress the opponent. To shoot accurately, it is still possible to do it only after opening the folding stock.

After some trial, Guan Fei removed all the firearms of foreign troops.

It is not a firearm designed for Chinese people, but it is still not used to it. Considering the continuity of weapons, it is better to choose domestic weapons.

Guan Fei looked at the domestic 03 and 95 series.

Type 03 is actually a folding stock. In fact, the muzzle feels like it is jumping sharply when shooting. Moreover, the stock and barrel are not on the same baseline, which affects the shooting accuracy when aiming and shooting. After a period of use, it will be much better after getting used to it.

Another thing that made Guan Fei not very satisfied is that in order to shorten the length of the gun body, the size of the buttstock must be ensured. The length of the barrel is shortened, and small-diameter bullets are used. Therefore, the initial speed is not enough, and the bullets fired feel a bit fluttering, and the hit accuracy and penetration power are not as good as the M series, and the penetration power is reduced compared to the AK series.

As soon as the 95 type is started, the first feeling is that it is very light. It is about three kilograms lighter than the 03 type, and it is much lighter than the M-type and AK-type. Even compared with the foreign military's unsupported rifle, it is lighter. Guan Fei put it against his shoulder and the center of gravity of the unsupported rifle was behind, and he immediately felt that the weight of the gun was large on the shoulder, and the posture of holding the gun felt very comfortable.

He fell in love with this kind of rifle immediately.

The head tilted slightly, and the gun body and the aiming hole were in a straight line. Without adapting to adjustments, you could almost immediately point where you pointed.

The actual shooting accuracy is also stronger than Type 03, and it also has a slight advantage compared to m16a2.

Moreover, due to its unsupported design, the barrel length reaches 49:5 cm, which is 5 cm longer than Type 03. Within a distance of 100 meters, the ballistics are very straight, and the 5.8 mm ordinary bullet easily penetrates the standard steel plate with a thickness of one centimeter. At the maximum shooting distance of 700 meters, it actually penetrates the standard steel plate with a zero point of three centimeters. It can be found that its penetration is quite good.

In terms of this power, before the enemy is equipped with level 4 and level 4 or above protective equipment, Style 95 can kill the enemy quite a lot.

Guan Fei's heart was already slightly biased towards this gun.

There are also many sturless rifles designed abroad. Some guns have higher shooting accuracy than Type 95, but the processing accuracy requirements are also very high. In order to reduce weight, composite materials are used in large quantities. Guan Fei cannot make composite materials, and there are countless formulas. However, high-quality composite materials have an outrageous requirements for raw materials and production lines. This is not something that the military sub-district can do now.

Some raw materials can be purchased from abroad, but in this era, the prices of these materials are quite high. If you buy them alone, it is neither economical nor safe, and it is easy for the other party to cut off external supply channels.

In fact, Type 95 is not that easy to do, and the external engineering materials of the gun body also require a special production line to be built.

However, the raw materials for production can be purchased in large quantities in the country, so there is no need to worry about out of stock.

After the vacuum electroslag remelting furnace is available, the ability to manufacture the barrel and internal metal parts is also available, and the heat treatment equipment is complete. There is no need to build more supporting production lines to achieve mass manufacturing, and the cost and manufacturing difficulty are greatly reduced.

However, the Nine Five is not without its shortcomings. On the contrary, it has serious defects inherent in the studless rifle.

For example, the early version of the magazine was made of plastic, which was low in strength and could not achieve empty room hang-up. In the fierce battle, there was no prompt, and it was difficult for the soldiers to find out whether there were bullets;

For example, if the grip is too high, you need to poke your head when shooting, which can easily increase the risk of head exposure;

The most serious thing is the unsupported rifle. The shell-spreading window is too close to the soldier's face. The hot shell can easily burn the face when thrown out. The smoke after firing will also interfere with the sight, irritate the eyes, and affect shooting.

Fortunately, China has invested a lot of effort in this rifle and continuously improved it. 95-1 and 95-2 improved models have been successively released. Most design defects have been corrected, such as reducing the height of the handle and reducing the exposure range; installing pickantine tactical guides to install high-precision scopes and other accessories, etc.

After actually using 95-2, Guan Fei confirmed that this gun type has been very mature, fully tapped the design potential, and was very satisfied with all aspects of performance.

Especially after more than ten years of improvement, the Jiuwu series has become a series. From full-size automatic rifles to short-barrel assault rifles, to squad light machine guns for drums, to bullet chains, heavy machine guns using heavy barrels; accessories from ordinary optical sights to infrared night vision aiming, grenades and micro individual missiles have formed a complete gun family system.

This left Guan Fei a lot of energy.

But even though he had detailed appearance and parts parameters, he still couldn't make it directly.

Weapons are also machinery. A machinery only knows the appearance size, strength and toughness of each component and other parameters, and wants to create the same thing, which is tantamount to dreaming.

If it is really so easy, the domestic technical level will not be worse than that of foreign countries: no matter how they are blocked and get a small amount of samples, they can still be done in China, and this is also done.

But what if you get these samples?

Technicians and scientists measure each component the most carefully inside and outside, record its installation order, and take photos to save the bottom. However, even if the drawings are restored, there is no suitable material, and the processing technology of each component, as well as the local heat treatment and chemical treatment processes, they are helpless.

Getting advanced foreign equipment can at best point out a way for the country's scientific and technological development, proving that it is right in this direction, and can strengthen R&D determination and accurately invest R&D funds. At the same time, the appearance and mechanical structure of parts can also help domestic scientists reduce R&D time, that's all!

The experiments that should be done must be done. If you don’t do them, you cannot master the design parameters of the entire machine. Without these parameters, even if someone’s things are 100% restored, the other party will be confused by it if you make a little modification - you don’t understand why you need to modify them like this, there are no formulas or parameters.

It was finally copied and you released an improved version. The internal structure has changed. Isn’t this a trick to us?

Therefore, even if it is a copy, you must repeat the research process of others to collect complete information. After encountering the other party improving it, we can immediately understand why and whether it is useful based on the collected design parameters.

Moreover, after you have truly learned a technology, perhaps the other party has not made any improvements, but we can come first and make new products with better performance. This is the advantage of latecomers. Blindly imitating and copying can only harm others and not benefit oneself, and it is meaningless.

But Guan Fei was not going to walk again, which was too easy for him.

He has various materials and formulas in later generations. He only needs to understand the size of the parts and the stress level of each part, so he can easily find the best combination from it. Then, using the same design and different materials, he will immediately launch a product with the same shape as the outside and the inside, but it is made of different materials and processing technology.

And because its materials are better, perhaps the cost, manufacturing difficulty, and performance are even better than the original version!

This is the same as the United States' engines that came to the Soviet Union will never follow the other party's manufacturing process, but will use its more developed manufacturing technology and material formula to process engines with better performance than Soviet original products.

The United States and the Soviet Union have done this more than once.

However, the United States copied the other party's equipment just to understand the design direction and help its own scientists explore their ideas. However, the Soviet Union could not make it even if it got the other party's equipment. It could only try to develop the same materials and processing technology, or use its own materials and base itself on its own manufacturing technology to imitate them.

Guan Fei now acts as the United States, analyzes all the size data of the 95-2 type and the parts parameters, and then proposes to the biological auxiliary brain to "take out the existing processing capabilities of the military sub-district, make up the material formula within 20 years, and copy the design drawings and processes of this model of firearm."

Just a command, countless design drawings immediately appeared in front of Guan Fei.

Each design drawing replaces some or all of the original parts and materials, using materials that can be smelted by the military sub-district. Different replacement solutions have different effects on the original design, with high or low performance, and simple or complex manufacturing processes.

Guan Fei thought about it repeatedly and finally chose two design plans.

One of these two solutions is the best comprehensive performance, but with the current technical capabilities of the military sub-district, the manufacturing requirements are too high. It is impossible to do many links unless Guan Fei takes it himself. It is possible to use a small amount of manual manufacturing from China, but there is no need to think about efficiency. It is the greatest achievement of the hard work of the masters.

However, Guan Fei also decided to make a small amount of this fine product to provide it to snipers in the army.

The performance of the other model can only be said to be fair and moderate, and is at the mid-to-downstream level among all design solutions. Compared with the original version, some data is still lower.

But it has an advantage, that is, it can be fully manufactured in large quantities based on the current technical capabilities of the military sub-district, and the cost is not too high. After calculating the production lines that need to be replenished construction, based on the basis of only 10,000 units, the cost of a single gun is about 2,000 yuan, and the barrel service life is 40,000 yuan, which is basically the same as that of European and American guns, and it is not good or bad.

Of course, it is several times higher than that of domestic gun barrels, which needless to say.

But this is really not worth the pleasure.

Two thousand RMB is almost equal to one thousand US dollars, which is more expensive than the US military's m16. This price is affordable for forces like Guan Fei who are rich and have a small size. Other major powers such as the United States, the Soviet Union and China dare not say that they have equipment for all the troops.

Too luxurious!

But Guan Fei had no choice. He had to follow the economic laws of an era in an era. The cost of this solution was relatively low, but the materials were not expensive. He had a vacuum electroslag remelting furnace. If the alloy materials required in the formula were not put into the production line and started to be manufactured from primary material processing, it could only be solved by purchasing in this era.

But in this era, technology is still too backward, and the cost of material production is too high, so I can't save money even if I want to.

Guan Fei sighed.

This is the so-called limitation of the times. Even with biological auxiliary brain assistance, he has no choice but to accept it.
Chapter completed!
