Song Wujin said that he would do it, and soon found the drawings, wiped a handful of oil on his mouth, and began to draw sketches with Liu Fei.

After some design, Liu Fei combined the receiver of the Barrett M82, the barrel and bipod of the AP and the bolt of the Mauser rifle, added the cushion stock, the counterweight trigger and the muzzle multi-function thread, and at the same time, in order to prevent the explosion caused by excessive chamber pressure, Liu Fei also thickened the barrel wall to 11 mm. But this also shows a problem, in this case, the weight of the whole gun goes up all at once. And now there is no good way to reduce the weight, because the materials used are already the bare minimum, and if the material is reduced or the label is lowered, there may be a big problem before the large-scale assembly.

Liu Fei was thinking about it, and Song Wujin was also thinking about it.

Suddenly, Liu Fei shouted: "Teacher, I think it may be possible to use aviation steel." I'm not talking about the steel used to build the shell of an aircraft, but the special steel used to build an aircraft engine. These steels are even half as dense as ordinary steels, but they have very good properties. As long as there is support from the rare earth industry, I don't think mass production is a big problem. ”

As soon as Song Wujin heard the aviation materials, he suddenly lost his mind: "But these materials should be attributed to strategic resources, and we can't use them because of research." ”

Liu Fei said with a smile: "Who said that this is a strategic resource, our Liu's power produces this kind of steel for engines." At present, there is no performance comparable to this kind of steel, so where do the strategic resources come from? ”

Song Wujing's eyes lit up: "Is this really okay?" ”

Liu Fei thought about it: "We can borrow the equipment and raw materials in the materials laboratory, and I believe they should be more than happy to lend it to us." ”

Song Wujin opened the door of the laboratory, intending to go with Liu Fei to find something to do experiments, but saw his assistant in a daze with a dinner that had been hot for an unknown number of times.

※※※After a few bites of food, Song Wujin took Liu Fei and hurried to the materials laboratory. Liu Fei personally operated a huge electric furnace to refine the steel he needed, and then processed the steel into one-cubic-decimeter-sized ingots and long steel rods that could be easily transported.

In addition, because of the human factor, Liu Fei left a few steel ingots here for their research, after all, this thing was also made with other people's electric stoves, didn't it?

……

After returning to the weapons laboratory, Liu Fei and Song Wujin worked together to start the machine tool, and as the cutting knife turned again and again, the steel forged into a rod was roughed into the shape of a gun barrel.

Then Liu Fei started the boring machine and began to draw rifling, in order for the bullet to rotate at high speed, Liu Fei pulled eight rifling, and the barrel length exceeded 990 mm. In this way, with a large projectile, sniper rifle bullets can hit a very long distance, even heavy machine gun bullets.

Liu Fei took the barrel that was processed as a whole to quench it, and then put it aside.

……

When Liu Fei finally processed the gun, it was already noon the next day. Song Wujin had fallen asleep on his stomach at night because of lack of energy, Liu Fei pulled the bolt, and he felt good. So I found a piece of scrap steel and processed a muzzle brake, and after installing the brake, the gun is basically completed, because there is no scope and sniper rifle cartridge, Liu Fei did not install a scope, and the bullet fired is designed to be a 12.7×108mm machine gun bullet.

Liu Fei fumbled for a while and then found the shooting range, which was built underground, and it looked like it was surrounded by very thick steel walls.

Liu Fei opened the bipod and put it on the sandbag, and then took a chain of 12.7×108mm machine gun bullets used by the Type 85 heavy machine gun from the ammunition storage on the side.

The soldiers who looked at the ammunition depot and the gate of the shooting range looked at Liu Fei with interest, and the students from other places were also very curious to look at the sniper rifle in Liu Fei's hand.

After Liu Fei dismantled the five bullets, he loaded them into the magazine, and after adjusting his target position to 800 meters, Liu Fei calculated the data and began to enter the state of emergency loading of local tyrant gold.

With a huge gunshot, Liu Fei successfully pretended to be a comparison (three fat: look at people, pretending to be more professional than pretending), and a huge hole appeared in the position of the ten rings of the target in the distance. Although Liu Fei wore earmuffs, the huge gunfire still stopped Liu Fei.

……

Song Wujing, who was sleeping on his stomach, heard a faint gunshot, and thought something was wrong, so he immediately ran towards the shooting range. Because the heavy guns that can emit such a huge gun sound must be more than 12.7 mm caliber, but most of these heavy guns are machine guns, and it is impossible to finish with just this one shot. So this is more like the detonation of a bullet, and if something so big happened, he, as the dean who is also the head of the department, naturally wants to go and see it.

Because it was the shooting range under his jurisdiction that came from the amazing sound of gunfire, if something really happened, it was his own responsibility, so Song Wujin's speed was even faster.

※※※When Song Wujin came to the shooting range, looking at the target paper that was full of holes on the target position, he was suddenly not calm.

So Song Wujing actively reported to the higher authorities, got a positive reply, and allowed the production of 100 sample guns for testing. A hundred improved models to be exact.

Because the performance of this gun designed by Liu Fei is reliable, and Liu Fei has improved most of the designs that may cause failures as much as possible before it was designed, Liu Fei can directly use it for production.

Because it has not yet entered the stage of mass production, the production is on the lathe. on production.

Although the cost of this is very high now, it is still much cheaper than importing or manufacturing strategic sniper rifles from overseas. So a group of military bigwigs, including Yang Zhijun, began to be tempted, although they liked large-caliber guns very much before, but after the Annan self-defense counterattack, they found that in fact, sniper rifles and cannons are an effect. Even a sniper rifle can withstand the suppressive effect of an artillery battery, so the importance of sniper rifles can continue to rise.

How can I do it.. And.. The country does not have enough supporting facilities, although the old. Maozi almost emptied Zeiss (Zeiss knows it, optics is good, it's great), but old. Maozi never gave a total of .. And.. The national rabbit is aided by even a little optical equipment. Common.. And.. There is another huge problem in the country that is just as big as the engine problem, and that is the material problem. If the engine is tan... The heart of the K aircraft armored car battleship, then the engine problem is the heart .. Sickness; So for these things, there is another important thing is the material, and the material is not qualified like having a bone disease.

A weapon with bone disease is not a good weapon if it is broken (by mistake) in the middle of the war. So by now, total.. And.. None of the countries has been able to produce strategic sniper rifles that can be mass-produced and equipped with armies. Most strategic sniper rifles need to be imported, and domestically produced ones are expensive and cannot be installed on a large scale.

It is precisely because of various reasons that the gun made by Liu Fei was able to get a trial production order.
