Through complex calculations, Yang Bin believes that there are two options, one is to use a 20mm large-caliber anti-materiel sniper rifle, and reduce the range to 2,000 meters in exchange for the maximum fire extinguishing warhead.

The other is to choose a domestic 40 mm caliber sniper grenade rifle.

Taking the LG5S 40mm sniper grenade launcher jointly developed by China North Industries Company and a number of domestic enterprises as an example, the LG5S sniper grenade launcher has a mass of 12.9 kg without drums and sights. With a total length of 1.225 meters, it can be carried and launched by one person, and is suitable for fighting in jungles, mountains, urban street battles, and airborne and other complex conditions.

At a distance of 800m, it can accurately kill living targets, carry out armor piercing for lightly armored and other targets, and carry out accurate fixed-altitude and fixed-distance air bombing and removal of targets hidden behind obstacles.

In addition, if necessary, the tripod can be erected to the highest position of the fortified structure or the terrain of a specific terrain for shoulder firing at a range of more than 2,300 meters for fire coverage.

The LG5S sniper grenade launcher is mainly composed of a body tube and receiver assembly, a receiver casing assembly, an automaton, a launcher, a bomb feeder and a bipod.

These characteristics are also suitable for extinguishing fires at a distance of 800 meters from the point of fire. Moreover, the weight of the fire extinguishing agent that can be carried by the LG5S sniper grenade launcher bullet can be twice as much as that of a 20 mm large-caliber anti-materiel sniper rifle cartridge at a precision strike distance of 2000 meters.

Therefore, after Yang Bin made accurate calculations, he called Mu Tianyu back.

"Xiaoyu, there are two choices, what do you think?"

"Brother Bin, please speak."

"First, fire extinguishing at a distance of precision from a distance, such as 2,000 meters, with a 20mm anti-materiel sniper rifle, can basically extinguish 1 cubic meter of flame."

"Wow, such an accurate number!" Mu Tianyu said with admiration, and asked Yang Bin again: "Brother Bin, what is the second choice?" ”

"Second, for accurate fire extinguishing at a distance of 800 meters, you can choose a domestic LG5S sniper grenade launcher, which carries twice the fire extinguishing dose of the 20mm anti-materiel gun and can extinguish 3 cubic meters of open flame."

"As far as I know," Mu Tianyu heard Yang Bin mention the domestic LG5S sniper grenade launcher, and felt that it was not very useful, so he said: "The diameter of the three-bullet dispersion circle of the LG5S sniper grenade launcher at 800 meters is 0.7 meters, although the fire extinguishing range is acceptable, but the distance and accuracy effect are worse than that of the 20mm anti-weapon gun." ”

"Yes," Yang Bin immediately added, "but if you use a foreign 50mm series of grenade launchers, then it must be fine." ”

Mu Tianyu immediately said to Brother Bin that he wanted Jin Chen to discuss it as well, and after Brother Bin agreed, he turned on the three-way conference call mode.

He briefly explained the situation to Jin Chen, and Jin Chen immediately understood the key to the discussion, and said: "The muzzle velocity of the warhead of the foreign 50mm series grenade launcher reaches 400 meters per second, which is longer and more accurate than the LG5S sniper grenade launcher, and the weight of the warhead reaches 500 grams. ”

Mu Tianyu heard Jin Chen's praise for foreign 50mm series grenade launchers, so he hurriedly called up the information. It turned out that this was a new type of equipment developed by a foreign hydraulic company that produces equipment for auxiliary means of warfare and to disperse rioters.

This 50mm series grenade launcher is a fixed-mount grenade and shoulder-fired weapon, mainly in two models: 50A and 50C. The main purpose of the development of this transmitter is to be used by the troops as an auxiliary means of warfare, such as smoke screens, lighting, anchoring, etc., and can also be used by the police to disperse the rioters.

But precisely because of what Jin Chen said, this 50 mm series grenade launcher has a very high muzzle velocity of the warhead, and the firing range and accuracy of hitting the target have been greatly improved.

The main structure of this 50 mm series grenade launcher can be seen in several features: it has a detachable inflatable container to provide high-pressure gas for firing. When firing, use the trigger to control the inflation valve, pressure limiter, and release valve.

The safety button on the trigger prevents the rear end of the firing tube from opening when it is in standby. In addition, if the rear end of the firing tube is not tightly closed, the trigger cannot be fired.

Because of this structural feature, the 50mm series grenade launcher can fire a variety of multi-purpose grenades, including anchor bombs, smoke bombs, flare flares, anti-riot bombs, etc.

The main performance data are: 50 mm large caliber, muzzle velocity of 400 meters per second, maximum pressure 21 megapascals, muzzle kinetic energy 2 kJ, launcher mass 7.5 kg, warhead mass 500 grams.

"Okay," Yang Bin heard Mu Tianyu and Jin Chen singing and harmonizing, he must have wanted a 20mm large-caliber anti-materiel gun and a matching fire extinguishing bomb. In addition, they wanted a 50-mm series of grenade launchers, as well as matching fire extinguishing bombs.

The 20mm large-caliber anti-materiel gun is easy to get your hands on, but it costs a little more, and the black market price is as high as $10,000. Thinking about the Jiangcheng plan, it is not bad to introduce 20 mm large-caliber anti-materiel guns and train a group of talents on the grounds of fire scientific research.

The 50mm series of grenade launchers, although defined as combat-assisted firearms, and for use by riot police, may be simpler to introduce. But there is very little information about this grenade launcher, and Jane's Defense only introduces it. It is not known whether it has been put into use and produced.

However, the concept of launching a grenade with high-pressure gas, which can also increase the muzzle velocity to more than 400 meters per second, is already quite technical. It is precisely this point that has long aroused Yang Bin's interest and made a very in-depth study.

The muzzle velocity of the bullet reaches supersonic speed, which means that the range and shooting accuracy can be greatly improved.

"That's it," Yang Bin said to Mu Tianyu and Jin Chen, "Just because you two are very knowledgeable, then I will try my best to meet your requirements." One is to get these two weapons, and the other is to develop fire extinguishing bombs. ”

Mu Tianyu was of course happy to hear it, but he knew that he couldn't say thank you to Brother Bin.

But Jin Chen didn't have this concept, and immediately shouted as soon as he was happy: "Thank you so much, Brother Bin!" ”

Yang Bin doesn't care about Jin Chen anymore, he doesn't like to "learn" with him as much as Cui Hongmei. Because of that Sister Hongmei, she especially appreciates Jin Chen's aura for shooting.

Yang Bin also thought of Cui Hongmei at this time, and he had to discuss with her immediately, how to do more with less money, and quickly get a batch of those two weapons.

Of course, the country's arms business is carried out through various normal channels. Cui Hongmei of course has a very important link, in her shooting club, she has the latest guns in the world, no matter what.

Even if she didn't, she could get it quickly. However, I won't talk to readers about the arms business here, and I won't talk too much about firearms, because I'm still talking about firefighting brothers.
