"I heard the pimple say, they are now making sample guns, and they have reached the final stage, but they will definitely come back for the New Year!"

Long Yun also said faintly: "In a blink of an eye, we have been in this Trojan County for more than a year......"

"yes, it's been more than a year!"

Lin Shiwen said, in this year, too many things have happened, Trojan County has grown from scratch, so many people have died, even including her father, sometimes she feels that this day is too long. Huo Ran Wen ??? ???．? ｒａｎｅｎ`ｎｅt

The snow is still falling.

In the snowflakes, Zhang Zaixian was busy with a group of kitchen people, preparing some food needed for the New Year.

Rice ball noodles, Chinese cabbage, white flour rice, etc......

Outside the county seat, a special area was set aside in the regiment, where chickens and pigs were raised intensively, in order to provide eggs and meat for the soldiers.

The people have chickens, ducks, pigs and sheep and the like, but after all, those are the people's things, the regiment is not easy to take in vain, this farm is directly under the regiment, usually the water pigweed or something will be fed, after the autumn harvest, these big fat pigs and chicken bran grain can eat a lot, the fat is fast, the New Year should be able to eat a meal, as long as there is no large-scale plague, eggs or something The soldiers should eat a little bit every three or five times.

This is Lu Yuan's idea, and Su Yan immediately put it into practice, this guy, as long as he hears something that can open up sources and reduce expenditure, his eyes will glow with gold.

On the outskirts of Trojan County, Luo Youcai and his brothers from the engineer battalion were busy working in the snow, a team of more than a dozen people, reinforcing the potholes with cement and gravel, and then covering them with mud to form a dark fort, and then registering them with a map.

While they were busy, from time to time, small groups of soldiers with loaded guns and ammunition rushed through the wind and snow to kill the next location, which was the reinforced battalion, and the first and second battalions were conducting snow field training.

Even as the year approached, preparations for war did not stop at all.

Recently, the weather has deteriorated, and the air brigade has stopped a lot, and the people can finally sleep peacefully in the morning.

But how could Chen Tianmin let those pilots rest?

Under his supervision, the pilots were busy working in the hangar every day, disassembling and disassembling the fighters, and disassembling them after loading, and they could not be washed clean all over their bodies.

In the cement factory and steel plant, people come and go, everyone pushes a wheelbarrow and braves the wind and snow to move forward, which is the direction in which the people in the liberated areas transport cement and steel bars to the dam, and the long transportation team can stretch for more than ten kilometers.

The water flow of the dam has been cut off, and the soldiers of the Eighth Route braved the severe cold to jump into the mud to dig pits, drive piles, and change a wave of people every ten minutes, and they were bruised and bruised without the slightest complaint.

Because they all know that all this is not for a certain person, a certain party, but for winning this war.

Everyone in this land, the soldiers of the Eighth Route Army, the Sichuan Army Independent Regiment, and all the people here are composing loyal hymns with blood, and they are all using thin shoulders to truly describe a heroic epic of victory!

In the semi-underground arsenal, hundreds of workers and technicians are working intensively, some are using various self-made simple scale instruments to measure the data of each handmade part, some are trimming with files, and some are assembling.

The first batch of 10 prototypes is gradually taking shape.

The whole gun is 1.2 meters long, weighs 5 kilograms, has a caliber of 6.5, a barrel length of 65 centimeters, and a ammunition capacity of eight rounds.

Different from the formal bolt-action loading in the 38 rifle, this rifle uses a gas-conductive rotary locking bolt, after the gun is fired, the kinetic energy of the bullet is used to jump out of the cartridge case and urge the next bullet to be loaded, so as to pull the trigger to shoot, without having to pull the bolt again to unload the cartridge case, effectively maintain the continuity of firepower, so as to achieve the transformation from bolt-action rifle to semi-automatic rifle.

This gun is based on the M1 Garand rifle, the main battle rifle of the US army a few years later, and at the same time, it has been modified to meet the needs of the Chinese battlefield.

The first is the caliber, the original M1 Garand rifle was 7.62 caliber, and this gun was changed to 6.5 caliber, this is because the Sichuan Army Independent Regiment is generally equipped with 38 rifles captured from the Japanese army, which can use the existing caliber bullets to the greatest extent, and the bullets of the 38 rifles captured on the battlefield are also available at any time.

Another point is the length of the barrel, which is also a few centimeters longer than the Garand rifle, which is for white-knuckle combat.

After all, the conditions here are difficult, unlike the US army, which has an unlimited supply of bullets, once the bullets are finished, they must be ready to start white-knuckle combat, and lengthening the length of the barrel is conducive to increasing the length of the whole gun, so that in white-knuckle combat, at least in the length of the bayonet stabbed out, it will not fall behind.

The main reason for choosing the M1 Garand rifle as a prototype is that this gun has high shooting accuracy, is easy to disassemble and clean, and is also very durable.

Ten hand-made semi-automatic rifles lay quietly in front of Lu Yuan, with dark color and hardwood supported body, exuding unimaginable beauty.

Lu Yuan picked up the first gun, reloaded, and shot.

"The bullet is deflected very much, check the rifling of the inner chamber, is it not symmetrical enough!"

After briefly saying the question, Lu Yuan picked up the second gun, reloaded, and shot.

"The muzzle velocity of the bullet is too slow, and it seems that the length of the barrel needs to be reduced by half a centimeter!"

"The gun spring is not strong enough, tell Pan Haodi, experiment with a new alloy to transform the gun spring, fast!"

At every order, technicians and workers immediately followed Lu Yuan's requirements and raced against time.

In the steel factory, Pan Haodi pulled his hair desperately, holding a pen in one hand and quickly writing more combinations of alloys on the papyrus, trying to complete the task assigned by Lu Yuan.

Experiment after experiment, dismantle, reassemble, shoot again, test firing.

Everyone's eyes were red, food was brought in when they were hungry, and they had forgotten the last time they had stepped out of the semi-underground fortifications.

，！

Continuous gunshots, no more than a second apart!

The bullets landed on the target two hundred meters away in succession, and eight dense bullet holes no more than two centimeters apart were fired around the heart.

"Good marksmanship!"

"Captain Lu, your marksmanship is amazing!"

The technicians slapped desperately, looking at the gun in Lu Yuan's hand, as if looking at a beautiful woman who had stripped off her clothes, full of tenderness and sweetness, this is their painstaking work in the past month, and it has not been vetoed by Lu Yuan yet. (To be continued.) )
