On the eve of the anti-eagle movement: the country urgently called me back home!

Li Yunlong is an experienced commander, he knows the anti-aircraft weapons needed on the battlefield.

He envied Chu Yunfei so much, he could be covered by planes, tanks and artillery just by moving.

He was drooling.

At present, the People’s Liberation Army”does not” have a real air force, otherwise, the enemy’s planes captured during the founding parade would not fly more times.

It was really helpless.

Li Yunlong looked at the scattered parts on the blueprint. He was illiterate and could not understand the blueprint.

“Jiang Chen, why are you asking me to look at this…Isn’t this just a gun?”

“That’s right, Lao Li, don’t underestimate it… this thing can masturbate!”

“You can brag all you want, I don’t believe it……”

“If you don’t believe me, you’ll know when I make it.……”Jiang Chen continued to ask:”Besides anti-aircraft weapons? What else is lacking on the battlefield?”

“For infantry, it is certainly a suitable rifle!”Li Yunlong’s mouth can be more and more greedy.

At first, he thought the Japanese Type 38 rifle was good, and later during the War of Liberation, he thought the Garand rifle was also good.

Now, even the Garand rifle is not worth mentioning!

“OK, I’ve got that down…anything else?”

“Of course…it would be best if we could get some powerful artillery…the Japanese Type 92 infantry gun is too weak, and the American 105 and 155 howitzers are too bulky.……”

“Although these guns have their own advantages, they always feel incompatible with the tactics of our People’s Liberation Army.……”

“OK, I’ve got it all!”

Finally, Li Yunlong asked,”Jiang Chen, when can we have our own planes and tanks?”

“One year!”

What? One year?

Li Yunlong’s eyes were filled with disbelief.

……

After understanding the specific needs of the troops, Jiang Chen started to get busy. He first started to make the M82 Barrett sniper rifle.

The M82A1 semi-automatic sniper rifle adopts the principle of short barrel recoil and semi-automatic firing mode. It uses the large-caliber 12.7×99 mm ammunition of the Browning M2 heavy machine gun.

Jiang Chen has asked Zhao Tianming to deal with the bullets.

The next step is the parts of the Barrett.

The M82A1 sniper rifle is disassembled into three parts: the upper receiver, the lower receiver and the bolt carrier.

The disassembly pin is located on the right side of the receiver, one in front of the magazine.

The other is near the bottom plate of the butt. The upper and lower receivers are the main parts.

The lower receiver connects the bipod, the gunner’s bottom plate and the grip, and its interior includes the bolt parts and the main spring device. The upper receiver mainly includes the barrel part, that is, the barrel, the barrel recoil spring and the buffer. The mechanical sights, the optical sight seat and the handle are welded to the upper receiver, and the barrel bushing and the barrel stop pin are welded to the inside.

After firing, the gunpowder gas pushes the bullet forward along the barrel, and at the same time acts on the bottom of the cartridge case.

The thrust is transmitted to the bolt, and then to the barrel sleeve by the bolt locking lug, and finally to the rear of the bolt frame through the bolt body.

This can disperse the vibration generated during shooting to avoid damage to the locking mechanism.

Almost all of these can be produced in a gun factory.

Therefore, Jiang Chen only needs to disassemble the parts and hand them over to the production below.

However.

In order to ensure its strength and wear resistance, Jiang Chen chose high-carbon steel material.

This requires materials expert Qiu Siyan to determine.

Qiu Siyan has a sweet appearance and fair skin. Even a military uniform cannot hide her bumpy figure. She wears a military cap and two braids casually draped over her chest. She is dressed in a very retro style.

“Director, I was just looking for you.”

Before Jiang Chen could speak, Qiu Siyan asked,”According to the design, your 12.7×99mm bullet is made of high-carbon steel.……”

“Currently, smelting plants are unable to smelt this type of steel……”

Jiang Chen:”Comrade Qiu Siyan, I’m looking for you because of the high carbon steel material issue!”

“I have a solution……”Jiang Chen tried hard to recall the metallurgy subject he studied at Harbin Institute of Technology.

“Let’s go to the smelter!”

Jiang Chen then began to instruct the workers in the smelter.

After proper heat treatment or cold drawing hardening, high carbon steel has high strength and hardness, high elastic limit and fatigue limit, and decent cutting performance, but poor welding performance and cold plastic deformation ability.

“Due to the high carbon content, cracks are easily generated during water quenching, so double liquid quenching is often used, and oil quenching is often used for small cross-section parts.”

“Therefore, this type of steel is generally used in a medium-temperature tempering or normalizing state or in a surface quenching state after quenching.”

Qiu Siyan, who was standing aside, watched Jiang Chen speak clearly and her heart could not help but ripple.

Boom boom boom… puff puff puff… beep beep… bang bang bang…

The machines in the arsenal kept turning.

Soon, with the efforts of Jiang Chen and the workers, the first Barrett sniper rifle was completed.

Zhao Tianming, who came to deliver bullets, looked at the table full of parts and asked curiously:”Director, is this the new weapon you developed? ?”

“That’s right!”

Jiang Chen began to assemble all the parts.

Click… click…

Under the watchful eyes of the crowd, a 1.447-meter-long Barrett sniper rifle was unveiled.

With a caliber of 12.7 mm and a black gun body, it exuded an aura of majesty without anger.

Zhao Tianming:”Director, how powerful is this gun? ?”

“”Won’t we know after we give it a try?”

As they spoke, they came to the testing ground.

Li Yunlong followed and saw Barrett with bright eyes:”Jiang Chen, how can we let you do such rough work as testing guns?……”

“Let me do it!”
