A weapon, from design drawings, to argumentation, to production of finished products, and finally live-fire inspection, is definitely not something that can be completed in a short time. Hu Changyi’s advantage is that his system also has an auxiliary, which can conduct some simulation and demonstration.

, deduce the appropriate and inappropriate aspects of a certain design to achieve the best design.

Of course, Hu Changyi doesn't use much deduction now, and he just needs the system to help him draw the correctness of the drawings. Master-level gun design is not for nothing.

Well, these are all nonsense. Most of the weapons "designed" by Hu Changyi are "borrowing" many guns from later generations and optimized products. Of course, there are also original ones, such as AK for Mao Xiong's family and Bobosha

, sks semi-automatic these are the design drawings sent by the original version, without any optimization. Well, even if the 56 light machine gun is gone, its changes are still very good...

In the R&D workshop, Hu Changyi has personally taken the four-unit anti-aircraft machine gun on the ground, and also needs to use system assistance to analyze and detect the quality and performance of the product.

System subtitles: High imitation (Su) Deshka 12.7mm anti-aircraft machine gun (quad-mounted, modified), excellent quality... Hu Changyi directly ignored the introduction of these letters, and he would feel at ease when he focused on the quality.

"Haha... Changyi, I knew you had to come here!" Minister Zhang's voice accompanied by laughter, and his feet entered the workshop.

"Hello, Minister Zhang..." The soldiers of the guard platoon quickly greeted him, and Hu Changyi quickly installed the last part and stood up.

"You are busy, busy..." Minister Zhang waved his hand to stop Hu Changyi, and then searched in the workshop with great interest.

The R&D workshop is not big, and the most equipment is for the final polishing and assembly. The equipment for producing parts is all on the machining side. Therefore, Minister Zhang inspected the workshop in three steps and took a special look.

Hu Changyi's newly renovated four-ring sniper rifles.

"Your workshop is good, it's much spacious than the original workshop. At least some of these treasures are placed in places." Minister Zhang said the Horse Four Ring Sniper Rifle.

When you arrive at the shooting range, you will first carry the heavy machine guns that are equipped with single gears separately, then combine them in the shooting range shooting area, then double gears, and finally the most troublesome quadruple gears.

"This time, I originally planned to get two models, but later I added another model, which is the single-body gun model on the chopping board." Hu Changyi said.

"Haha, that's good, that's good! In this way, the bullets will be offline tomorrow, and we will try it at the shooting range the day after tomorrow!" Minister Zhang looked at the three guns with satisfaction and made a decision to experiment.

"The similarities? Except for the same caliber, the rest are different... Well, this bulletproof shield is the same, and the anti-aircraft rack is also very similar, but the others are not like it." Minister Zhang commented.

"Minister Zhang, you are here just in time. This new gun has been prepared. Do you think there are any similarities compared to the 12.7mm anti-aircraft machine gun from Mao Xiong's family?" Hu Changyi asked.

Now, the answer is revealed, the three big guys outside are now there.

"Here you come, wait there!" Su Wei leaned over and said.

It will be half an hour after all the guns are arranged. Well, this efficiency is so slow, but everyone is not familiar with it.

"Why, you still want to build some and sell them back to Mao Xiong's family? Their industrial strength is much stronger than ours." Minister Zhang joked and said, "This can prevent the Japanese planes?

”

"Hey, that's fine! It's easy to talk if you can't tell." Hu Changyi actually changed the biggest change to this gun was the appearance design, and the internal performance did not change much.

"I won't point it out. You are nominally experimentalists, but actually soldiers of our armored assault company. Seeing these three guns, the big guy in the four-unit is specially used for air defense and will be arranged in the future.

You don’t have any idea about this around our factory and around the headquarters. But you must master the dual-unit and single-handed ones. Now, come with me and I will give you the specific operation, and then you

Today and tomorrow, I will be familiar with them. Are those who participated in air defense battles before coming?" Hu Changyi asked.

Minister Zhang was very busy. After making the decision, he stopped staying and took a few officials to inspect the production. In the R&D workshop, Hu Changyi did ask someone to carry out all three machine guns.

In the yard outside, the single one here is a truly high-quality imitation Deshka. The remaining two are Hu Changyi’s reference to some other gun-shaped changes.

"Load the car, drag it onto that, and go to the shooting range!" It was not convenient for the factory area to fiddle with these firearms. Hu Changyi waved his hand and everyone went to the shooting range.

"All the experimental team came to report!" Just as everyone was curious, the experimenters arrived running from the shooting range, and a truck followed.

But no matter what, the three majestic heavy machine guns placed outside the yard immediately attracted many curious eyes. Especially the soldiers in the bullet production line workshop were even more curious. They all knew the line they were building.

The bullets made must be more than ten centimeters long, and I want to see what kind of big guy it is to be worthy of such bullets.

"The 12.7×108mm gun bullet, the bullet head or armor-piercing incendiary bomb and armor-piercing incendiary tracking bomb, the effective air defense height is 1,600 meters. If it is shot flat, 1,500 meters will ensure that people can be killed."

"Well, tell them that from today on, they will all leave their original units and be newly formed into the air defense company directly under the Logistics Department... Yes, it is the air defense company for the time being." Hu Changyi set up a new unit casually.

Soon, during the Jiuzhai defense war, the soldiers stationed on the surrounding mountains came to the shooting range and personally participated in the operation and learning of four-unit anti-aircraft machine guns and the common sense of simple plane masturbation.

Unfortunately, the Eighth Route Army is too poor. There is no target machine to attack them, so they can only aim and train the "image enemy" in the sky. Well, in fact, dual-mounted and single-standard are easy to operate, as long as the machine is

The gunman has the strength, knows how to measure in advance, learns to use aiming equipment, and cooperates with the ammunition hand to give the bullets.

The more difficult one is that the four-unit machine gunner needs to sit and lie on the operating table and shake the handle to adjust the height and angle of the machine gun.
