"I've learned about this gun!"

At this moment, Liu Mang is quite confident, unprecedented.

"I know more than you Ye Cunxin eats!"

In his previous life, before he crossed over, Liu Mang was a fan of military hobbies.

For the TV series of special forces, the movie is very enthusiastic, and at the same time, I am also very keen on the military magazines of various countries, and I have an understanding of most of the weapons in the world.

Whether it is firearms, mines, grenades, or cold weapons, all aspects of running in the sky, running on the ground, and escaping in the sea are involved!

"You ......"

Liu Mang's words were there, and Ye Cunxin, who was directly scolded, turned red for a while, and he couldn't speak for a long time.

"Okay, you say you understand, then you can tell me what type of sniper rifle Barrett M82A1 is!" Ye Cun was not convinced, she didn't believe how much Liu Mangyi Barrett knew, and what she knew was just a few skins.

"Semi-automatic sniper rifle with a short barrel recoil principle and semi-automatic firing." Liu Mang said coldly.

"The principle of the short recoil of the barrel was developed by the famous firearms designer Browning, and Barrett improved this principle to make it suitable as an automatic principle for shoulder-fired weapons."

After a pause, Liu Mang didn't wait for Ye Cunxin to say anything, and continued: "M82 is a semi-automatic firearm with a short recoil barrel, and the barrel will be about an inch back seat when firing, and at this time, the chamber is still safely locked by the rotary bolt after a short recoil -

The bolt unlocking protrusion is pushed into the curved unlocking slot on the receiver, and the bolt rotates to unlock the barrel. When the bolt is unlocked, the bolt accelerator arm is instantly pressed back, and a part of the recoil energy of the barrel is transferred to the bolt to complete the action cycle.

After that, the barrel backseat is in place and is fixed by the bolt to continue the backseat, ejecting the cartridge case. During the bolt repetition process, the bolt pushes a bullet from the magazine and feeds it into the chamber, and finally the rotary bolt and barrel latching firing pin returns to the standby position. ”

"Unexpectedly...... Do you know so well? ”

At this moment, hearing what Liu Mang said, He Zhijun, Fan Tianlei, and Tan Xiaolin showed surprise on their faces.

"How do you possibly know this?" Ye Cunxin couldn't believe that what Liu Mang said was even more detailed and clear than she knew, which made her a little unable to accept this reality in her heart.

"I also know that the magazine of this gun can hold 10 rounds at a time, although there are also 12 round magazines, but it has not been produced after the first Wave Gulf War, and the magazine is divided into two parts, the upper part and the lower part, and the thin steel plate is stamped and then fastened with cross bolts.

The barrel has grooves for faster heat dissipation and weight reduction, and is also fitted with a large, highly efficient muzzle brake. Early muzzle brakes were conical, the new M82 was fitted with a double-bore, right-angled arrow-shaped, inverted-V-shaped, brake, which reduced recoil by almost 70%. Liu Mang sneered.

"The drawback is that the gunpowder gases ejected from the brake and back every time a bullet is fired will roll up a large amount of dust and loose particles near the shooter - the M82A1 can quickly disassemble into three parts: the upper receiver, the lower receiver, and the bolt frame. The disintegrating pin is located on the right side of the receiver, one in front of the magazine, and the other is near the bottom plate of the butt, and the upper and lower receiver is the main part, and high carbon steel is selected to ensure its strength and wear resistance."

"Oh my God!"

Tian Guo was shocked and said: "How can you be so handsome, even to Barrett M82A1, Liu Mang where he knows these things!" ”

"Oh my God, this is too detailed, we haven't understood it in such detail!" Tang Xiaoxiao also committed nymphomaniac.

"Skylark, this Liu Mang is a talent, when the Thor and they finish training Liu Mang, we must find a way to keep him in our Fire Phoenix!" He Lu looked at Liu Mang's extremely confident and eloquent appearance in the picture, and said with shortness of breath.

"A must!"

Tan Xiaolin was also shocked by Liu Mang's current professional answer to Barrett, and her eyes stared at Liu Mang in the picture with extremely hot eyes and said, "This is too genius!" ”

"Good boy!"

He Zhijun and Fan Tianlei looked at each other, nodded with a smile on their faces, and were quite satisfied with Liu Mang's detailed introduction to Barrett's operation.

"The Barrett M82A1 lower receiver connects the bipod, gunner's base plate and grip, which includes the bolt components and the main spring device. The upper receiver mainly includes the barrel part, that is, the barrel, the barrel re-entry spring and the buffer, which are welded to the upper receiver are mechanical sights, optical sight mounts and handles, and the barrel bushing and barrel stop pin are welded together with the inside. ”

When everyone was shocked, Liu Mang continued: "When the gunpowder gas is fired to push the warhead forward along the barrel, and at the same time act on the bottom of the cartridge case, transmitting the thrust to the bolt, and then the bolt is locked and protruding from the bolt to the barrel sleeve, and finally transmitted to the rear of the bolt frame through the bolt body. This disperses the vibrations generated during firing and avoids damage to the locking mechanism. ”

"Can you go into detail?"

Liu Mang sneered at Ye Cunxin, and then asked Tan Xiaolin again for instructions: "Report, I request that the weapon left by the enemy be used in the next period of time, Barrett M82A1!" ”

"Yes!"

Faced with Liu Mang's request again, Tan Xiaolin responded without hesitation.

"The lark can't do it!" Ye Cunxin spoke up again.

"We all know what he said before, but we haven't been in contact with the back, who knows if he is talking nonsense!"

After a pause, Ye Cunxin continued: "Besides, this Barrett's recoil is so big, save his thin body that is about the same as a railing, and before the enemy hits, he was killed by the anti-shock force!" ”

"And the two chiefs haven't said anything now!"

"Comrade Ye Cunxin, Liu Mang is now alone in the center of drug dealers armed to the teeth to open up a safe road for our fighters to attack, I hope you don't interfere with his combat thinking!" He Zhijun suddenly said in a deep voice.

"As for what you are saying now, what he said later, you really haven't understood, but it doesn't mean that others haven't understood!"

"A lot of times, what you can't do, and on behalf of others can't do it!"

After speaking, He Zhijun stared at Liu Mang in the picture, and said solemnly: "Comrade Liu Mang, if you have enough confidence and strength to control the Barrett M82A1 that you have never used——

I allow you to use it! ”
