Heroes of Silver Moon

Simon walked around in the operating room, feeling very depressed. The structure of this bolt-action rifle seemed simple, but it was quite difficult to actually manufacture it.

It's been a long time, and Simon hasn't thought about what the thing that fixes the firing pin is.

Fixed firing pin, firing pin hitting primer, firing pin reset, reset? Simon's eyes lit up.

It turned out to be a spring, but he actually forgot about it!

There is no such thing as a spring in this world, so Simon can only make it himself.

Things like springs have very high requirements for industrial machinery, but thanks to Simon's heaven-defying control over magic steel, this does not bother him.

Manipulating the liquid magic steel, Simon made a spring that fits the firing pin in a short while.

Covering the firing pin with a spring, and then reinserting the spring and firing pin into the bolt, Simon started another simulation.

The simulation was good this time. The "trigger" transmitted a force to the firing pin, and the firing pin passed through the small hole at the front of the bolt and slammed into the primer of the bullet.

Then under the action of the spring, the striker returns to its original position.

While the exact details are somewhat rough, the structure is unmistakably this structure.

After finishing the gun bolt, Simon turned his attention to the gun case.

That is to install the bullet, store the bullet, push the bolt to load the bullet, the firing pin fires the primer of the bullet, and pull the bolt again to eject the case.

This part is quite simple. Simon first opened an ejection port at the end of the gun body aimed at the baseline.

This ejection port is closed by the bolt when the bolt is closed, and is revealed when the bolt is pulled back.

Below the ejection port is a magazine that can accommodate five rounds of bullets. The user can press the bullets into the magazine through the ejection port.

A spring plate is installed at the bottom of the magazine, which can push the remaining bullets to a suitable height after the last bullet is fired.

Simon made five model bullets out of magic steel, and then started experimenting.

There is no problem with pressing the bullet into the chamber. The bolt pushes the bullet into the chamber. There is no problem.

Pull back the bolt, eject the spent cartridge case, there is a problem!

Simon pulled the bolt back and found that the shell casings were still in the chamber, and they were not ejected at all when the bolt was pulled again.

Putting down the half-modified model gun, Simon rubbed his sore eyes.

The sky outside the window was a bit dim, which meant that Simon had been in the operating room for a whole day.

He ran to the academy cafeteria for dinner, and then Simon returned to the operating room.

So far, he has restored less than half of the bolt-action rifle's structure.

Playing with a model bullet, Simon thought about ejecting the shell.

The barrel and the ejection port are misaligned, that is to say, after the bullet is fired, it cannot be thrown directly through the ejection port.

It must be pulled back through the bolt to give the shell a pull back force.

But the front end of the bolt is a smooth cylinder, and the cartridge case is also a smooth cylinder. What is the relationship between the two smooth cylinders?

The model bullet that Simon was playing with kept turning over at Simon's fingertips.

One inadvertently, the model bullet slipped from the fingernail and fell on the operating table.

Simon was taken aback for a moment, and then he was about to pick up the model bullet again. He picked up the model bullet casually, and Simon suddenly noticed something strange.

Why is there a circle of grooves at the connection between the primer and the propellant?

Putting the model bullet in front of his eyes, Simon carefully observed it.

This model bullet was restored from his imitation memory, basically the shape of the rifle bullet on Blue Star.

The conical bullet, the cylindrical shell, and at the very bottom, a not-so-deep dent separates the primer and the main body of the bullet.

From the perspective of the structure of the bullet, this circle of dents is completely unnecessary!

Because even without this circle of dents, inside the bullet, the primer and propellant are separated!

The dent at the end of the bullet, the pulling force brought by the bolt back to the shell, and the shell was ejected at the ejection port. The three clues were connected in series by Simon.

Simon's eyes lit up, and he understood that there should be a circle of barbs at the very front of the bolt.

When the bolt pushes the bullet into the chamber, the barb at the front end of the bolt should fit into the groove at the bottom of the bullet.

In this way, when the bolt is pulled back by the user, the cartridge case in the chamber will also be dragged by the barb ring of the bolt, and move horizontally backward.

When the bolt pulls the case to the ejection port, the underside of the tail of the case should just hit something in the way.

In the case of horizontal motion, the lower part of the tail of the bullet is hit, and an upward force is bound to be generated.

This upward horizontal force is the key to ejecting the shell.

As soon as he thought of it, Simon immediately added a circle of barbs to the front end of the bolt, and installed a small hard iron block at a suitable position below the ejection port.

Then, as Simon expected, during the experiment, when the bolt was pulled back, the bolt really pulled the shell back through the circle of barbs~www.readwn.com~.

When passing through the ejection port, under the tail of the bullet, it hits the small iron block below the ejection port, and then the model bullet is ejected directly.

Under the force of the spring plate at the bottom of the magazine, the bullet in the magazine moves up one position, the bolt is pushed forward, and the second bullet is sent into the chamber.

"Well," Simon let out a long and exhausted breath.

After refitting for a whole day, he was exhausted.

Now the barrel, bolt, magazine, and general structure have been completely restored.

Next, as long as the trigger, transmission parts, and aiming baseline are restored, the general structure of the bolt-action rifle is completed.

It was getting late, and Simon dragged his tired body back to the dormitory. As soon as he entered the door, he saw Mike lying on the bed reading a book.

"Yo", Simon greeted casually.

Mike heard the greeting, put down the book in his hand, and glanced at Simon unexpectedly.

Since Simon was summoned by the king, he has been missing. He, Guy and others have not seen Simon for a long time.

If it weren't for the occasional glimpse of Simon, the group of them would really think that something happened to Simon.

Mike asked a little puzzled: "What are you doing these days, the whole thing is mysterious?"

Simon yawned with his hands covered: "Practice! Practice! I'm making things every day now."

Lying directly on the bed, Simon moaned comfortably.

Mike obviously didn't believe it, but he didn't want to pry into Simon's secret too much, so he just said, "There is a party at the end of the month, will you go?"

After hearing this, Simon nodded with his eyes closed. No matter how busy he has been recently, it is indeed time to promote relationships with Guy and the others.
