After the manufacture of the 40mm grenade fuse was completed, the 40mm anti-personnel grenade equipped with the gun-mounted grenade launcher was also successfully trial-produced, and the gun-mounted grenade launcher was also manufactured.

However, Lu Jiadong did not blindly imitate, after all, the QLG-10 type is the supporting equipment of the Type 95 stockless assault rifle, in order to adapt to the Type 95, so the barrel of the gun grenade launcher is very short, and the Type 78 assault rifle is a typical conventional layout of firearms, if you copy the products of the later Type 95, it is obviously impossible to adapt to the Type 78 firearms.

Therefore, Lu Jiadong made improvements in the QLG-10 machine tool, such as lengthening the body barrel, from the original more than 200 mm, to 375 mm, to adapt to the longer barrel of the 78 type, and the mechanism for attaching the gun body was also simplified, in addition to the installation of the gun tactical guide system.

There is also a set of spare card lock system, as long as the lower half of the 78 firearm handguard is removed, it can be fixed on the firearm with a spare card lock, of course, the gun-mounted grenade launcher at this time also has the function of the firearm handguard, and the shooter can not always hold the metal tube of the gun-mounted grenade launcher when shooting.

Originally, Lu Jiadong wanted to solve this problem by coating a layer of engineering plastics on the jacket of the high-strength aluminum alloy body tube, but he never thought that the national chemical industry was still underdeveloped at this time, and engineering plastics were still in short supply.

Due to the use of front-loading ammunition, the number of rifling, the casso, the insurance, the mechanical sight and other mechanisms are basically the same as the QLG-10 type, the only difference is the problem of locking the ammunition in the chamber, Lu Jiadong has optimized on the basis of the QLG-10 type, and changed the original paddle to a button.

As for the supporting ammunition, after solving the fuze problem, Lu Jiadong designed an integrated ammunition without a cartridge structure, and specially developed a new type of front-loading primer, the previous primer was loaded from the bottom of the ammunition, and then fixed by riveting, but the primer designed by Lu Jiadong was the opposite.

He sets up a boss on the primer, and the installation of the primer is not installed at the usual bottom, but is loaded into the bottom of the bullet from the front of the projectile body, and the boss is fixed at the bottom of the ammunition, so that the structure of the ammunition is not only compact, but the bottom of the bullet can also be better integrated with the fixed mechanism of the gun grenade launcher, and the ammunition is firmly fixed in the body tube!

Of course, after the integrated treatment, the weight of the ammunition was also rapidly reduced to 190 grams, and more than 380 regular fragments were prefabricated internally, with a range of nearly 500 meters and a killing radius of nearly 14 meters.

"Bang!~~Boom!" On the shooting range of the militia company of Wanshan Factory, Wu Tianming was holding a Type 78 assault rifle with a grenade launcher attached to the gun, and the boring mouth of the grenade launcher was still emitting a faint smoke and dust at this time.

The planks a few hundred meters away were being shaken by the sound of the explosion just now, the planks closest to the explosion point were damaged and tattered, and the planks a few meters away were also dotted with holes.

"Oh my God!" Seeing that the gun mounted grenade launcher had such a destructive effect, Wu Tianming, who was born as a scout, couldn't help but be shocked:

"If this squad rushes forward in a dense formation, this guy can kill them all!"

"The most important thing is that after you finish firing the grenade, you can continue to hold the gun, and even if there is a fish that slips through the net, you can shoot the first time to destroy the enemy!"

As soon as Wu Tianming's words fell, Chen Zihao on the side clasped his hands to his chest and said indifferently, but what he said was not original, but repeated what Lu Jiadong often said in the design of the gun grenade launcher, but looking at Chen Zihao's calm appearance, it was as if he said it.

Others don't know the inside story, but Wu Tianming doesn't know yet, so when Chen Zihao finished speaking, Wu Tianming pouted: "Okay, you, don't learn Jiadong there!" After speaking, Wu Tianming turned his head to Lu Jiadong:

"This gun-mounted grenade launcher is powerful, easy to use, and most importantly, it does not occupy the establishment, as long as the infantry equipped with guns can be configured, it is indeed a fire support weapon urgently needed by the troops!"

After listening to Wu Tianming's words, Lu Jiadong nodded, but there was not much joy on his face, but he asked a little eagerly:

"Hanging the gun and hanging the grenade launcher, the overall quality of the gun has increased, and there will always be some impact on shooting!"

"It doesn't increase the weight of three catties, that is, the recoil is slightly large, and it doesn't have much impact on the overall performance of the firearm!" Wu Tianming turned the gun sideways and handed it to Lu Jiadong: "Don't believe it, you try!"

The reason why Wu Tianming has such a move is because he knows Lu Jiadong's ability very well, especially in the finalization test of the Type 78 assault rifle, Lu Jiadong's firearm skills are not as good as him, a professional soldier from a scout, of course, after returning to Wanshan Factory, Lu Jiadong did not break his promise, and passed on the stunt of changing magazines with one hand to Wu Tianming, even so, Wu Tianming still admired Lu Jiadong's gun skills.

Although Wu Tianming handed over the firearm, Lu Jiadong did not take it, because he had tried it himself before, and he felt the same as Wu Tianming said, and the reason why he still asked like this was because he wanted to hear the opinions of professional soldiers, after all, the real user in the future would be a professional soldier like Wu Tianming.

Wu Tianming obviously knew what Lu Jiadong meant, so he held up the gun: "Jiadong, don't worry, this thing we developed, the infantry of the field army must be the favorite, use a grenade within 40 meters, and use a gun-mounted grenade launcher at 40 to 400 meters."

400 meters away with 60 force, solid targets use 40 fire, so calculated, if it is a reinforced company, from 40 to 1000 meters range to basically achieve full coverage of firepower, plus our Type 78 assault rifle, with such firepower, whether it is defense or assault, it is definitely enough for any enemy to drink a pot"

"Who is enough to drink a pot?" Wu Tianming's words were not finished, a familiar voice came from behind him, Lu Jiadong couldn't help but turn around, and found that it was none other than Li Ming, director of the Military Quality Inspection Department of the Provincial Department of Science, Technology and Industry for National Defense.

This time, they came to Wanshan Factory, mainly to investigate the production of Wanshan Factory's Type 78 assault rifle and the quality control of other military products, which is a routine matter of their military quality inspection department, and they have to come over every few months to investigate and investigate, so Lu Jiadong was not surprised by Li Ming's arrival, but greeted him cordially and shouted:

"Director Li, Director Liu!"

"What's the matter, Xiao Lu, I heard that you have come up with something new again, take it out and let Director Li and I also open our eyes!" Seeing Lu Jiadong coming over, Liu Haotian got straight to the point and asked Lu Jiadong directly.

After several contacts, Lu Jiadong knew that Liu Haotian was a straight man, with one thing to say and two to say, and he would not beat around the bush with you, so when he asked, Lu Jiadong's face flashed a faint smile, and then pointed to the Type 78 assault rifle with a gun-mounted grenade launcher in Wu Tianming's hand:

"Right there!"

Liu Haotian looked in the direction of Lu Jiadong's guidance, and found that a small steel cannon-like body was installed in the position of the handguard, and under curiosity, Liu Haotian took the firearm in his hand, touched the body of the gun grenade launcher with his hand, and then looked at Lu Jiadong suspiciously:

"How did you load the grenadiers into the guns?"

"This one, it's called a 40mm gun-mounted grenade launcher, not a grenadier!" Chen Zhen, who was standing behind Liu Haotian, explained to him with a smile.

"Gun hanging grenade launcher?" Liu Haotian looked at the unfamiliar equipment in his hand, his brows couldn't help frowning, and then looked at Li Ming:

"Lao Li, how do I remember that there is no such thing in the project declared by Wanshan Factory!"

Listening to Liu Haotian's words, Li Ming was also puzzled, but looking at Lu Jiadong's smiling face, and then recalling the plan of the Type 78 firearm tactical matching accessories declared by the Wanshan Factory a few months ago, Li Ming couldn't help but suddenly realize:

A few months ago, when I looked at the so-called integrated tactical fire support system for firearms in your application materials, I wondered what this thing was, but I didn't expect it to be this!"

"Firearms Integrated Tactical Fire Support System?" Hearing what Li Ming said, Liu Tianming also thought about it: "Is there such a thing, no one in the hall understood it at that time, but I didn't expect it to be this thing!"

"Two division chiefs, it is written in the materials we declared, this gun grenade launcher is indeed used for infantry tactical fire support, and there is nothing wrong with the name of the firearms integrated tactical fire support system, besides, you have all given instructions on it, but you can't go back!"

"Look at this little Lu!" As soon as Lu Jiadong's voice fell, Liu Haotian pointed at Lu Jiadong with a smile: "It's really unforgiving, hehe, since you have come up with something new, you have to try it first, but don't regret it and look at this guy's performance!"

Lu Jiadong and the people at the Wanshan factory who were present all knew that Liu Haotian was saying the opposite, and since the provincial department had signed the reply, it was naturally impossible to go back, but Liu Haotian should have proposed a test launch, after all, as a higher-level competent department, he should also be clear about the actual capabilities of the new equipment.

Liu Haotian is worthy of being a veteran who has been on the battlefield, Wu Tianming only taught it once, and then mastered the essentials, so after loading and aiming, Liu Haotian pulled the trigger of the gun-mounted grenade launcher with his right hand, only to hear the sound of "bang!" and then a violent explosion sounded in the wooden plank array a few hundred meters away.

Looking at the wooden plank array that had been blown up, both Liu Haotian and Li Ming were dumbfounded
