Utopia

Barrel.

As the name implies, it is the tube through which the shell passes when firing. It is also the most challenging part of the cannon.

Because the barrel has to withstand the high pressure and high temperature conditions generated when firing, if there is any problem with the quality, the barrel will inevitably explode, and the casualties of the gunners are even more difficult to avoid.

In this regard, Omer has been using [to be honest, I have been using it recently, both Android and Apple are OK.] 5mm caliber barrels recently, and he naturally studied it carefully.

As for why there are no other calibers... After all, they, Kalai, are not the first race to develop gunpowder weapons, let alone the first race to put gunpowder weapons on the battlefield. Many things are not that they can design them by themselves, but they have to slowly learn from the experience of Eastern humans to avoid detours.

"Hiss, if the gun mount of our 75mm gun can be used with the gun barrel of the 5mm gun that we have been using recently [to be honest, we have been using it recently, both Android and Apple can use it.], wouldn't it be more convenient..."

At this time, Sogen's unintentional muttering to himself immediately attracted the attention of a group of research experts such as Omer.

"What did you just say?"

"No, uh, I, I am just wondering if we can make our gun mounts universal. If we can, wouldn't we be able to save a lot of research time?"

"Hmm..."

Omer began to ponder over Sogen's words. In the next six months, although the fighting sounds coming from the northwest beach made Sogen and other guards nervous from time to time, the militia of Solo City, under the guidance of the guards, no longer needed the guards to come to help defend.

So at the Solo Arsenal, there was another new machine gun in front of the guards.

"Director, where did you get this back from?"

"First of all, Captain Nice, this was not obtained from normal channels. And this machine gun that fires the 3×99mm machine gun bullets that have been used recently is just a replica. What I know is that the prototype of this gun was dug out."

Listening to Director Farah's words, Sogen didn't understand what it meant to dig out. Could it be from a pit buried by artillery fire on a battlefield, or from an abandoned arsenal somewhere?

In short, he and other colleagues were surrounding this large-caliber heavy machine gun that weighed 58 kilograms and was almost two meters long. Although he now heard that the militia also needed a weapon that could effectively suppress the enemy's cluster impact at a long distance, and even destroy light vehicles, such as small transport ships.

But such a thing that is obviously overweight is their only choice?

You must know that their Kalai people are not human beings, and Eastern humans have a nickname specifically to describe them.

Bean sprouts.

This is a special term to describe their Kalai people as a vegetarian intelligent race, who are generally tall and thin.

So he suddenly had an idea in his mind, could he reduce the weight of this large-caliber heavy machine gun?

But he had learned a lesson from the pistol incident before, that the weight of weapons and equipment should not be too light, otherwise it would be difficult for the shooter to control the recoil generated when the machine gun fired.

And he carefully looked at this heavy machine gun that he didn't know where he got from, but there was not even a buttstock on it, just a pair of shovel-type grips behind the gun body.

Could it be that this machine gun fired by holding the shovel-type grip?

If this is really a machine gun used by Oriental people, then why didn't they install a buttstock?

Is it because they are very strong?

In short, all kinds of questions added up, that is, he returned to his room at night, opened his notebook and several professional books on the desk alone to analyze.

[Recommended, chasing books is really useful, download here, everyone can try it quickly. ]

"Here it comes again."

Sogen didn't hear what his roommate Ness said, but continued to write various theoretical analyses. In the next few days, he took advantage of the time between patrols to discuss with experts in light weapons such as Lehman, while continuing to analyze whether his ideas could make sense. By the way, during dinner, he also talked to Omer about his further ideas and opinions.

But compared to this, he saw the three white-skinned female Kalai representatives visiting the Solo Arsenal again. And this time, compared to the procurement matters, he heard something that made the guards quite embarrassed, but they had to accept it.

"Are we now united as the armed forces of the Negan Autonomous Government?"

"Yes. Captain Nice, I have discussed this matter with the Council of the Autonomous Government over and over again. After all, on the Gem Island, all of us Kalai members are actually independent armed forces. Therefore, from now on, you are the professional guards hired by the Solo Arsenal from the Council."

"Director, we don't object to this. Judging from the fact that we have actually surrendered to the protection of the Autonomous Government, the Solo Arsenal itself is now supported by the Autonomous Government and has become a licensed private arsenal. So we guards know this in our hearts. The question is whether we will be transferred from the arsenal and go out to fight in the future..."

"You can rest assured about this. The representatives of the Council Hall do not want your 400 guards to leave the Arsenal. They are eager to deploy more troops to defend such an important facility as the Arsenal. And they also agree that our guards must wear masks and be able to purchase weapons and equipment by themselves. But how is our artillery research going?"

Speaking of this issue, all the guards and technicians lowered their heads and said nothing, and Farah, as the factory director, nodded slightly. Because compared to guns, the problem of artillery is really fatal.

Without enough artillery, the army, which mainly relies on the brown-skinned Kalai members who do not understand magic and enjoy the benefits of the abolition policy as the main force of the autonomous government, is difficult to fight against the local druids or the cult troops blessed by the devil's power.

"Director, I do have a contingency plan here. But neither Sogen nor I can guarantee whether it will be effective, and it is even hard to say whether the final result will satisfy everyone."

"Technician Omer, what do you mean..."

"Based on the physical objects we got before, Sogen and I want to develop a two-in-one 84mm rapid-fire cannon and the 5mm howitzer that we have been using recently. The two guns use the same reinforced gun mount. The material of the gun barrel is the same."

As Omer handed the plan to Farah, a group of employees looked at Sogen and Omer. Especially the former, Sogen is the only armed guard who can research and even draw weapon design drawings. And the Yangman semi-automatic rifle, which is now listed as a standard rifle by the Negan Autonomous Government, is the result of his gas-operated automatic theory research.
