Doomsday Bunker Upgrade

It is not difficult to manufacture a Maxim machine gun. This kind of antique model is even sold on a certain treasure, and its unique toggle mechanism is not structurally complicated.

According to the drawings, Chen Xin used the system to retrieve materials from the storage room.

Although the manufacture of machine guns requires high-performance steel, ordinary steel is sufficient for the system, and the rest of Chen Xin can be safely handed over to the system.

With the help of the processing function of the workbench, Makqin's parts were manufactured, and these parts were assembled bit by bit. Soon a piece of Makqin appeared on Chen Xin's workbench.

Although he has not yet completed all the assembly, Chen Xin has only completed the barrel and the bolt action, without even the most important brackets. The unpainted body of the gun is entirely in the original metallic color and looks miserably white. But it did not conceal the might of this terrifying killing machine.

Maxim heavy machine gun, it is the world's first truly successful automatic weapon with gunpowder and gas as energy. Once applied, it has become the most efficient killing machine in human history.

In the war between the Japanese and the Lucias, Hitori Nogi, the **** of war, who was blown to the sky by the Japanese, led 60,000 people to attack the Lucian positions and adopted a very brainless pig rush tactic, and was killed in three hours. Five thousand people.

Although the Lucias were finally defeated, when the final attack came down, Nogi Hitori's 60,000 soldiers had already suffered more than 30,000 casualties.

In World War I, Maxim even won the title of widowmaker with its terrifying killing efficiency.

In the Battle of the Somme, the death firepower net composed of hundreds of Maxims caused more than 60,000 casualties in one day. In the First World War, almost a whole generation of people in Europe at that time was killed.

This horrible killing machine uses the recoil generated by bullets to achieve automatic shooting. Compared with the Nanwu Gatling Bodhisattva invented by federal doctors to reduce the casualties of soldiers participating in the war, the efficiency is much higher. It is also easier and more convenient to maintain, so it replaced Gatling soon after it came out.

However, because of its high rate of fire of 600 rounds per minute, Maxim produces a lot of heat when shooting, and within a few minutes the barrel will become red from the shooting.

Therefore, Maxim’s barrel will have a huge circular sleeve. Cooling water is injected into the barrel to cool the barrel. As long as there is water in the barrel, the temperature of the barrel will not exceed one. Baidu, you can continue shooting.

Some people may think that this weapon will have a huge advantage in cold weather, after all, if the environment is cold enough, the cooling effect must be very good.

But in fact, it is the inconvenience of Maxim when used in cold areas.

Because Maxim uses a water injection pipe to add cooling water, dripping into ice in cold areas, the cooling water must burn the ice and snow into water before it can be added to the barrel, and this often causes the cooling water to freeze and affect its use.

Therefore, to use in cold areas, antifreeze must be added to the cooling water, and the antifreeze that was widely used at that time was alcohol.

This is why there are stories about Lucia people drinking antifreeze, because the cooling water with alcohol added as antifreeze is really a delicious drink for Lucia soldiers who were called gray animals at that time. , It's okay to take a bite, who can't shoot the gun?

Later, in order to solve this problem, Sauvia learned from the Finns to improve the water injection port on the barrel of the gun body, turning it into a large flip cover, which can be directly filled with ice and snow, which effectively solved this problem.

Of course, for Chen Xin, he would not use such a troublesome method to cool down the barrel. After all, he is only one person, even if Qin Lan and Ding Ning come, there are only three people. The door is equipped with defensive weapons, and it is best to design it to be fully automatic. Yes, it is best to be remotely controlled in the shelter.

As for the problem of cooling, it may be a difficult problem for the people of Makqin's time, but for modern military industry, it can also be solved by replacing it with recirculating coolant and recycling it.

It's just that for the army, the air-cooled machine gun has already been replaced, and there is no need to smash on the water-cooled machine gun.

For Chen Xin, he doesn’t need to worry too much about the coolant. As long as he keeps the rate of fire low and doesn’t use it for a long time, Maxine made by modern technology does not actually have much demand for cooling and heat dissipation. The materials used are completely different.

Put the last part on the gun body, and add gun oil lubrication between the gun body parts, and a Maxin without a support frame is completed.

Looking at this iron guy like a round roller, Chen Xin stretched out his hand and patted it, trying to hug it with both hands.

Although it is a bit heavy, it is still within the range that Chen Xin can hold, but this is still a fixed weapon that requires a support frame. It is completely impossible to expect to hold it up and shoot like a light machine gun in a film and television drama.

So if Chen Xin wants to use this machine gun, he also needs to make a bracket for it.

However, when Chen Xin was preparing to make the stand, he suddenly remembered a picture he had seen before. After thinking about it for a while, he decided to make another one.

Because only steel is needed to make Maxim, the second Maxim also appeared on the workbench.

Seeing two identical Maxine heavy machine guns placed on his workbench, Chen Xin nodded in satisfaction and began to make the support frame.

Compared with the Maxim machine gun itself, its support structure is actually more complicated, because in addition to being a support, Maxim's support has many different functions.

Some have added anti-shields, which can resist the splash of stray bullets and fragments; some are equipped with seats and can be shot while sitting on the bracket; some simply integrate the spare barrel on the bracket, which can be removed and replaced when necessary ...

What Chen Xin did was to put two Maxines together in parallel, turning the original Maxin into a double installation.

Because of the original bracket structure as a reference, the double-mounted bracket is not difficult to make. Chen Xin only took a little time to make a bracket that can fit both Maxims.

Although the structure is a bit unreasonable and a bit crude, it is almost impossible to adjust the shooting range and angle, but it is still a complete bracket.

After installing two Maxim water-cooled machine guns, the name of the system interface changed from Maxim water-cooled machine guns to double-mounted Maxim water-cooled machine guns. Chen Xin only clicked on the upgrade.

It was still the familiar green light, the survival point of 100 points and the consumption of a part of the steel made the originally rough and crude double-pack Maxine instantly become different after the green light swept away.

The original white and miserable metal appearance turned black, and part of the structure was replaced by engineering plastics. The diameter of the thick water-cooled sleeve was reduced, but the length was elongated. Longer sleeves and longer barrels , While improving the heat dissipation performance, it also enhances the power of the bullet shot from the barrel.

The rudimentary bracket has also been upgraded, from the original simple three supporting legs to a complete supporting structure, and the movable connection structure that Chen Xin did not originally do has also been added. After removing the fixation, the gun body can be within a certain range Rotate to achieve multi-angle shooting.

The trigger part has also been modified, from two guns with two triggers to two guns with one trigger, which combines the structure and reduces the complexity of the operation.

As for the upper bullet mouth, it was adjusted to one side from the same side, and according to Chen Xin's vision, a large-capacity magazine was added to the upper bullet mouth.

This kind of large-capacity magazine still uses a chain, or simply speaking, the magazine is just an ammunition box containing bullets. However, due to system upgrades, this magazine has an additional bullet delivery mechanism. Attached to the machine gun, the bullet can be sent directly into the upper bullet port.

After completing the production of the machine gun, as long as this double-mounted Maxim is installed at the gate of the refuge, Chen Xin believes that without heavy vehicles or heavy weapons, no one can force in.

However, a machine gun has a shooting angle limitation. After thinking about it, Chen Xin decided to install two more appropriate.

As a result, he made another Maxim machine gun with the same twin-mounted configuration, and then prepared to install them on the door of his refuge.

Two machine guns were installed on the left and right sides of the gate by Chen Xin~www.ltnovel.com~ because the topography of the evacuation shelter appeared outside the gate. Although the surrounding snow was accumulated, the terrain was still flat. To enter Chen Xin's refuge, you must stand in front of the gate, which is within the range covered by the two double-mounted Maxim firepower.

Within this range, if there is not enough protection, no matter how many people are, they will only be screened.

In addition, Chen Xin installed these two machine guns in the wall and only opened a small shooting port. Even if he wants to destroy these two machine guns, he wants to destroy them without heavy firepower. The use of life piles can only consume Chen Xin's bullets in vain.

The large-capacity magazine has 200 rounds of ammunition, and two double-packs are 800 rounds.

Even if it is a burst fire, a single machine gun with two hundred rounds of ammunition is enough to sweep for almost one minute. If it is a short burst, if you want to consume these bullets, I am afraid that it will not take hundreds of lives to pile up.

Especially after Chen Xin installed the machine gun, he smashed the door with a thousand survival points and upgraded a lot of materials. While strengthening the strength of the door, it changed the manpower push-pull door to the electric hydraulic lift door. Two machine guns increase automatic aiming function, and install infrared night vision monitor and motion sensor on the gate.

The infrared night vision monitor and the motion sensor are directly connected to the computer in Chen Xin's bedroom, and are also connected to two machine guns. Chen Xin can operate them in the bedroom.

As long as a suspicious person appears and the motion sensor is triggered, Chen Xin will be awakened by the alarm bell in the bedroom, and the situation outside the door can be seen through the computer screen.

If someone is plotting something wrong... the four tongues of flame that are cross-covered are a nightmare even on the battlefield.
