Global Wasteland: Unlimited Upgrades for Vaults

Using the storage space, after moving all the surrounding steel materials into the garage, and picking up five units of copper, Su Mo nervously went to the second floor to turn on the generator.

The adventures of the past few days, even almost costing his life, were exchanged for the supplies.

Finally, on the last day, it evolved into strength!

Looking at the small thermal weapon laser manufacturing machine that has started to self-test, Su Mo's mood was agitated.

The steps to use the laser machine tool are not difficult. After adding the amazing modular technology, the manufacturing has been simplified a lot.

You only need to select the weapon to be made first, put in the required materials according to the requirements, pass the machine tool inspection, and then perform a fool-like placement operation, quietly waiting for the finished product to come out of the oven.

"Modular technology is indeed a good thing, but it's a pity that I didn't buy a single modular machine tool this time."

"But even if there are, these people may not necessarily sell them unless they are dying."

Shaking his head, putting away some greedy thoughts, seeing that the green light was on after the self-test was over, Su Mo lightly clicked on the m-1 rifle, and the material requirements popped up.

Three units of steel, two units of iron, one unit of copper, one unit of wood, two units of water, and...

Ten degrees electricity!

The machine tool also has its own battery module, which needs to be fully charged to ensure that it is higher than the manufacturing value before starting.

This is a requirement that may cause manufacturing failure or damage to the machine tool due to a sudden power failure.

Seeing that the fast charging has started on the lower right, Su Mo is not in a hurry, and sits patiently in front of the machine tool and waits.

The manufacture of firearms involves some seemingly simple but actually very complex specification requirements. For example, the manufacture of rifling is a very simple and very important part.

Rifling, also known as rifling.Because its cross-sectional shape resembles a windmill, it is also called a windmill line.

The rifling can be said to be the soul of the barrel. The function of the rifling is to give the bullet the ability to rotate, so that the bullet can still maintain the predetermined direction after it comes out of the chamber.

Although the use of rifling was recorded in the 15th century, it was not popularized until the 19th century due to the difficulty of the manufacturing process.

Without the relevant knowledge reserve, Sumo can only hope that the machine tool will be powerful, and there will be no mistakes!

Half an hour later, after the charging was completed, Su Mo looked divinely looking at the production button that popped up on the side of the machine tool, and gently put all the materials into the storage module of the machine tool, which currently only has one square meter, pressed the production button with both hands, and started First time making a gun!

creak!creak!

The ear-piercing sound was accompanied by a little trembling, and as the button was pressed, it began to burst out from the machine tool from the inside out.

A creepy high-pitched cutting sound not only startled Somo, but even the big and small sparks on the second floor cooed in fright.

The laser probe above began to rotate slowly under the force of the machine tool.

Before Su Mo had a good look at how the machine tool made weapons, an iron cover suddenly rose from both sides of the machine tool.

Driven by the motor, the cover began to slowly form a ball, leaving only a few cooling holes, completely covering the entire machine tool.

Then, a burst of dazzling light suddenly burst out from the heat dissipation holes of the cover, and the illuminated research room was abnormally bright.

The high temperature brought by laser cutting began to float out with the cooling holes.

Gradually, seeing the temperature getting higher and higher, Su Mo simply summoned the lion man's wind to cool the big iron ball.

When this cycle was repeated for 5 minutes, the light began to weaken.

puff!

With bursts of water vapor erupting, the cover also began to fall slowly, revealing the true face inside.

At this time, in the place where the finished product popped up, there was already a freshly baked gun with a distinctive shape and a very aggressive look.

Looking at the gun body carefully from the tip to the tail of the gun, Su Mo calmed down at the moment of harvesting.

When the green indicator light came on again, indicating that Su Mo could take the gun, the temperature of the m-1 rifle also dropped and reached a stable temperature.

Picking up the gun, Su Mo first felt the weight.

"Heavy but not heavy. An empty gun weighs about five catties. With bullets, it should be between six catties and six and a half catties."

After unloading the magazine, Su Mo checked the capacity.

The bullet specification of the magazine assembly is 5.56 x 45 mm caliber, and the stanag magazine similar to that on the earth is used, and the capacity is the standard 40 rounds.

"If you don't consider the pattern design that is different from the name above, it is really a pirated m4a1"

Touching the intricate pattern on the gun, Su Mo was not sure how powerful it was, so he could only try to continue to open the machine tool to make ammunition.

The m-1 rifle uses the m193 rifle bullet, which is the conventional 45mm caliber. This small-caliber rifle bullet has a huge lethality that is not commensurate with its size.

The m193 bullet has no steel core, and the bullet is filled with soft lead, and the copper skin wrapped outside the bullet is very thin, so the entire bullet becomes very soft.

After hitting the target, the bullet will deform and shatter quickly, and the fragments of the bullet will form a multi-hole penetrating wound (that is, a bullet punches several holes), causing severe bleeding.

However, the technology tree of guns is not as simple as simply making guns.

The biggest problem facing all wasteland humans at present is the preparation of ammunition.

Even if the current underground shelters are rich in materials, if you want to make suitable bullets, you need to continue to point out a new technology tree...

Smokeless Gunpowder!

Black powder burns slowly and has low pressure, resulting in low bullet velocity.

In order to achieve sufficient range and effect, simple physics dictates that the mass of the bullet needs to be large, and the caliber of the bullet is naturally larger.

Therefore, rifle bullets of more than ten millimeters or even 20 millimeters abound in the era of black powder.

In order to achieve better results, in the late black powder era, compressed black powder was loaded to increase the chamber pressure, which can also provide a speed close to smokeless powder.

When it comes to smokeless gunpowder, the burning speed is faster, and the pressure and temperature are higher, which brings faster speed, reduces the caliber and quality of ammunition, and reduces the logistical burden, but it also brings countless design changes.

Smokeless gunpowder brings smaller ammunition calibers, faster speeds, and straighter ballistics.

A flatter trajectory means less impact from range errors.

For example, in the trench warfare of World War I, it is common to hit the exposed head at about 300m, and it is likely that the difference from the zero point by tens of meters will result in a high or low impact.

And a straighter trajectory can reduce the height error of the trajectory caused by the distance, and it will be easier to hit the target.

"Although the preparation method of smokeless gunpowder in the TV series Hanyang is a bit exaggerated, there are also places for reference..."

Putting the m1 rifle on the work table, Su Mo began to think carefully about how to mass-produce smokeless gunpowder.

If you don't promote the development of the ammunition technology tree, no matter how awesome the guns are in the future, it will be useless without bullets.
