Xu Jianguo did not explain too much, but aimed this thing at the guide rail under the new gun handguard, and then pushed it gently. With a crisp "click", the under-slung grenade launcher was installed.
"Jianguo, what's the use of this thing?" Su Dingshan asked.
"Commander, don't underestimate this thing. For some special targets, rifle grenades can play a huge role. Simply put, you can compare this thing to a hand grenade, but its launch method is different from that of a hand grenade. One requires human throwing, and the other is like a bullet, which is launched through this launcher. Compared with hand grenades, rifle grenades not only save manpower, but also have a longer range and greater power. At the same time, with the strengthening of research and development, rifle grenades can be continuously upgraded. For example, if the rifle grenade is equipped with an armor-piercing warhead, then this thing will be lethal to tanks. If it is equipped with a high-explosive or incendiary warhead, then the lethality against some bunkers or hidden positions will be greatly improved." Xu Jianguo said with a smile.
After listening to Xu Jianguo's introduction, everyone, including Su Dingshan, looked in disbelief. They had never seen or even heard of this advanced individual combat weapon.
"Boy, are you kidding?" Su Dingshan asked after a long while.
"There is no joking in the army. I will not joke about such things." Xu Jianguo said with a smile.
"Okay, show it to us!" Su Dingshan said impatiently.
"Yes!" After Xu Jianguo finished speaking, he took the small box handed over by a soldier. When he took out the 40mm caliber grenade ammunition, there was immediately a sound of gasps in the field.
This time, Xu Jianguo chose to imitate the famous M302 under-slung grenade launcher. All ammunition sizes are also based on it. It adopts a 40*46mm low-speed grenade design. The advantage of this design is high accuracy and small recoil.
Because the ammunition uses a special design and is launched at low pressure, the chamber pressure in the barrel of the grenade is low when it is launched. The most intuitive benefit is that the recoil force when it is launched is only 18 joules.
Smaller recoil can form a better aiming baseline when the shooter is shooting with his shoulder, and at the same time greatly reduce the shooter's fatigue and the impact on the firearm. Because the under-slung grenade launcher is suspended below the firearm barrel, if the impact force when the grenade is launched is large, the force will be directly transmitted to the barrel through the connection, which may affect the shooting accuracy and service life of the firearm in the long run.
"Is this a rifle grenade?"
"If this thing hits someone, won't it smash them to pieces?"
"nonsense!"
"Damn it, if we had this thing back then, all of Chiang Kai-shek's magnesium-type equipment would have been a waste!"
"What nonsense! What about Chiang Kai-shek? If this guy had been around during the Korean War, he would have taken over the entire peninsula."
As the crowd started talking, Xu Jianguo pushed the grenade launcher's sleeve forward, and then pushed the ammunition in from the rear. With a crisp "click", it indicated that the ammunition was in place.
He then reset the sleeve, found Lu Jian in the crowd, and said, "Captain Lu, please find a grenade thrower so we can compare."
"good!"
A moment later, a young soldier came over and saluted them.
After Xu Jianguo returned the greeting, he asked, "How far can you throw a grenade?"
The soldier thought for a moment and said, "With a tailwind, I can throw it 60 meters!"
"Okay, you come first then!"
"yes!"
While everyone was waiting, a dilapidated truck was pushed into the shooting range by dozens of soldiers. It would serve as the target and complete its final mission.
When the truck was sixty meters away from the designed position, the soldiers stopped, quickly gathered in formation, and ran away.
At this time, a protective wall as high as one and a half meters had been built by the soldiers using sandbags. Everyone knew that the test was about to begin, so they returned to the observation seats and left their seats for Xu Jianguo and the young soldier.
"Report, everything is ready, request to start the grenade test!" Xu Jianguo shouted.
"Let's start!" Lu Jian said.
"Yes!" Xu Jianguo replied, then turned to look at the young soldier beside him and said, "Come down, don't be nervous!"
"Yes!" the young soldier said, and then he picked up the wooden-handled grenade on the table next to him, unscrewed the tail cover, pulled out the fuse, and threw the grenade hard at the scrapped truck in the distance.
The grenade drew a perfect arc and landed accurately next to the truck. With a loud "bang", the grenade suddenly exploded, and shrapnel flew everywhere. The large truck was affected by the shock wave and swayed violently. The glass and tires on one side of the vehicle were completely shattered, but the whole vehicle looked intact and did not cause much damage.
After the explosion, Xu Jianguo and the young soldier stood up from behind the protective wall. He looked at the big truck that was blown up by the grenade and gave the young soldier a thumbs up.
The young soldier smiled innocently but said nothing.
At this time, Xu Jianguo raised the new rifle in his hand, put the butt of the rifle against his shoulder, put his right palm on the magazine, and placed his left hand under the grenade launcher. He opened the safety with his left thumb, placed his right index finger on the trigger of the grenade launcher, put his right eye close to the white light sight, and pulled the trigger at the large truck in the distance.
With a muffled sound, the grenade was fired. Before everyone could react, a large truck in the distance made a loud "bang". The whole vehicle was instantly surrounded by flames, and countless parts flew everywhere. In the blink of an eye, it was blown to pieces.
"Hiss!" Everyone's eyes widened instantly, and they couldn't help but gasp for air.
After a while, there was a burst of loud cheers and applause in the venue.
"Good, it's enjoyable! Really enjoyable!" Su Dingshan said loudly, slapping the table.
Ma Guoliang, who was standing next to him, was trembling with excitement and didn't know what to say for a moment.
Just as he was stunned, Su Dingshan had already put the telescope on the table and walked towards Xu Jianguo with big strides.
Seeing this, Ma Guoliang hurriedly followed.
"Hahaha, kid, you are not bragging. This thing is much more powerful than a grenade. Hurry up, load one for me so that I, an old man, can have some fun too!" Su Dingshan patted Xu Jianguo on the shoulder and said with a hearty laugh.
At this time, the people in the General Staff and the Jingzhou Weapon Research Institute were already numb with shock. They didn't understand why they, who were professionals in weapons research and development, could not design such a powerful individual weapon.
