Bright Sword starts with the grenade flat.

Chapter 16 Change paper to iron, glue to welding!
  However, the reason why bullet shells are classified is naturally because the appearance of some bullet shells is not good, such as being crushed on the battlefield. Naturally, such bullet shells cannot be loaded directly.

And some bullet shells are not all the same. For example, the little devil uses a 6.5-caliber bullet, while the Zhongzheng rifle used by the Eighth Route Army has a 7.92-caliber bullet, plus the little devil's 92-caliber bullet. The heavy machine gun uses 7.7 caliber bullets, so these bullets must be classified.

When the soldiers were cleaning the battlefield, they didn't have time to sort bullet casings. They would pick up any bullet casings anyway.

After all, no matter what type of bullet casing, whether it is good or bad, it is copper! Even if the broken bullet casing cannot be reloaded, the brass jacket used to make the warhead can be melted.

Of course, when sorting bullet casings, Liu Xiu deliberately left a lot of bad bullet casings, and then secretly made a silencer made of brass. That's right, it was cast. Compared with parts processed by lathes, .

It is much simpler to cast things with sand molds. The reason why Liu Xiu came up with this method to make a silencer is entirely thanks to Lao Ba, because before time travel, Liu Xiu often used to The handicraft workshop at Lao Tie directly uses sand molds to produce various parts and tools.

Even some parts of the firearm can be cast with sand molds. As for the accuracy, I can't praise it, but it can still be used!
  Of course, Liu Xiu had never thought about getting a steel melting stove. After all, that thing didn't have oxygen blowing. Ordinary carbon stoves couldn't melt steel at all, but copper was different. A charcoal stove could easily reach more than a thousand degrees, the melting point. Copper with a thousand degrees is still light.

As for the internal structure of the silencer, Liu Xiuna naturally understood it. After all, there were a lot of things on the Internet before the time travel. It was just a pipe. Inside it were several bowl-shaped silencers with holes in the middle. When assembled, it became a The silencer is gone.

Its shape is very simple, and you can basically make it easily after seeing its structure. Of course, there are not only internal structures of silencers on the Internet, but also many internal structures of various firearms.

There are many hand-made masters who have used paper shells to perfectly replicate the structure of this firearm one-to-one, which has naturally attracted countless fans.

With the popularity of this kind of paper-shell firearms, there is also a popular saying, called paper to iron, glue to welding, three small meals a day! You do the cutting, I do the carbon, and the buzzword for at least eight and a half years will come out tomorrow.

Liu Xiu also caught this trend, and because he liked it, he followed suit and made many one-to-one paper gun models.

Of course, it’s not just that. Liu Xiu will also shoot videos of himself dismantling real guns at the shooting range, as well as videos of competitions when participating in IPSC competitions. With the support of such various means, Liu Xiu even achieved better results than the first launcher. This kind of video anchor also needs hot viewing data.

In his previous life, it was precisely because of this opportunity that Liu Xiu easily gained millions of fans. It is precisely the support of Liu Xiu's millions of fans that allows him to devote himself wholeheartedly to IPSC shooting competitions and practice shooting bullets in the shooting hall. After all, he does not have enough money to support him. This bullet costs more than ten yuan. Shooting training costs hundreds of dollars per magazine, and it won't take long for Liu Xiu to be depleted.

What's more, the monthly membership fee for joining the IPSC Club and CQB Club is also a large expense.

Because there is no lathe, the silencer is not fixed to the muzzle with spiral threads like most silencers, but with fixed bayonet pins to fix the silencer to the barrel. After installing the silencer, the appearance of the Southern Fourteen pistol in Liu Xiu's hand suddenly changed drastically. The appearance level was improved by at least three levels, and it was no different from the appearance of the Ruger Mark IV pistol. .

The Ruger Mark IV pistol is also known as one of the best-looking pistols. It is said that this pistol refers to the design of the Southern Fourteenth pistol when shooting, but it has been optimized in appearance to make it more beautiful. Beautiful, so even though it uses the least powerful .22 bullet, it is still welcomed by a large number of gun enthusiasts.

After all, the power may not be good, but the appearance must be handsome, which is also the first choice for all good-looking gun lovers.

The reason why the appearance of the Ruger Mark IV pistol has been so greatly improved is mainly because it is equipped with an integrated cylindrical gun shell, so that the gun body is no longer thick at the back and thin at the front, and looks like a chicken leg. Similarly, the chicken drumstick of the Southern Fourteenth Pistol also comes from this.

Liu Xiunong's silencer wraps the entire barrel, so from the outside it looks like the gun body is as thick as the front and rear, just like the Ruger Mark IV pistol.

As for why Liu Xiu added a silencer to the Nanfang 1932 pistol but not to the other pistol in his hand, the Mauser M, the main reason is that the Nanfang pistol is very suitable for silencers.

You must know that the source of the gunshot sound when shooting a firearm can include three parts. The first part is the sound made by the movement of the gun. If you shoot without loading the gun, you will hear a click! Click! The sound is the sound of the gun movement and impact.

The second sound is the sound produced by the flame ejected from the muzzle when the bullet flies out. This flame is the sound of the high-temperature and high-pressure gas generated when the gunpowder burns rapidly expanding in the air. It is precisely because of this high-pressure gas The push of gas allows the bullet to fly close to the speed of sound, or even exceed the speed of sound.

The function of the silencer is to limit the rapid expansion of the high-temperature and high-pressure gas at the muzzle in the air, confine the flame to a relatively small space, and then repeatedly intercept it through the silencer bowl inside the silencer, causing the gas to explode. The expansion speed slows down, so the sound naturally becomes smaller.

As for the last sound, it depends on the situation. If the bullet fired is subsonic, it will not produce much sound. If the bullet is supersonic, it will produce a large sonic boom. This is why Liu Xiu The reason why I chose the Nanfang Fourteen pistol to install a silencer is because the bullet fired by the Nanfang Fourteen pistol is only 1932 meters per second, so it is naturally a subsonic bullet and will not produce a sonic boom, while the Mauser M The pistol fired supersonic bullets at more than meters per second.

Therefore, even if a silencer is installed to limit the sound of the muzzle flame explosion, the sonic boom generated when the bullet flies is still not small.

After Liu Xiu installed the silencer, he also tried firing a few rounds. The silencer effect made Liu Xiu very satisfied. The reason why Liu Xiu wanted to make a silencer was naturally because Liu Xiu planned to go to the county town when he had time. Go find the father of this body.

The main reason why he wanted to find his father was that when Liu Xiu was sorting out the memories left by this body, he discovered something was wrong with his father, because in his memory he not only owned a Southern Fourteenth pistol, but also handed him a man. But I also taught him the words and calligraphy of a little devil.
