Three days later, at the western foot of Phoenix Mountain, the Sichuan Arsenal Shooting Range.

Dozens of Chinese and foreign technical experts from the Ordnance Research Institute shouted excitedly and shouted loudly, and both German and Chinese technicians, whether German experts or Chinese technicians, warmly embraced each other and were overjoyed.

The two directors and deputy directors and four engineers of the Sichuan Arsenal, who were fortunate enough to participate in the finalization and acceptance, were envious, and surrounded Xu Xiaogang, the Sichuan overseer, and Bao Jiqing, who had become the commander of the Chengdu headquarters and the commander of the aviation training base, and kept pleading and strongly demanding to undertake the task of producing the new machine gun, and finally said that they were willing to get the production authorization of only one of the machine guns.

Xiao Yimin, whose ears were buzzing, was in good spirits, and he couldn't tell that he had vomited blood three days ago and was unconscious, and the dozen generals and several personal guards around him had just passed a machine gun addiction, and they were still full of praise for the two new machine guns at this moment.

Half an hour later, the sun was already in the west, and the six sample guns that had gradually cooled down had been taken back by the experts of the research institute, and more than a dozen Chinese and foreign technicians brought five or six delicate large wooden boxes, first spread two brand-new green military blankets on a long tabletop, and then quickly opened the wooden boxes, took out five new submachine guns, and carefully placed them on the military carpet, four of them opened the bullet box, pressed the yellow-orange Balabrum pistol bullets into the narrow magazine, and the other two Chinese technicians ran to the front target, The logistics officers and men were requested to re-set up three sets of targets: 50 meters, 100 meters, and 150 meters.

Xiao Yimin didn't wait for Max and Weiss to come to invite, so he walked to the test firing place excitedly, and after listening to Weiss and the two experts' systematic introductions, he immediately couldn't wait to grab a submachine gun, and the more he looked at it, the more he loved it, and finally couldn't help laughing.

In Xiao Yimin's mind, there is a kind of nostalgia for the Bergman MP18 submachine gun called the flower machine gun, and at this moment, the brand-new submachine gun without a porous heat sink looks more pleasing to the eye, the design is more advanced, and it is more comfortable to hold in the hand, which made Xiao Yimin obsessed for a while, if it weren't for Weiss's dissatisfied cough, Xiao Yimin was probably reluctant to put down the beautiful submachine gun in his hand.

More than a dozen generals consciously stood behind Xiao Yimin, and dozens of technicians naturally surrounded Weiss and Max in the middle.

Weiss and Max discussed a few words in a low voice, raised their heads, cocked their beards and introduced with great pride: "General, everyone, first of all, I would like to thank Mr. Max for his outstanding leadership, thank all my colleagues in the institute for their joint efforts, and thank General Xiao and all the officers and soldiers of the Chengdu headquarters who have supported us and defended us!" It can be said that this gun embodies the precious painstaking efforts and collective wisdom of all our Chinese and foreign technicians and developers. ”

Xiao Yimin was quite moved, and took the lead in applauding to show his appreciation, and the warm applause rang out neatly for a while, and it lasted for more than 30 seconds before stopping.

Weiss held the gun and excitedly introduced: "On the basis of the German Bergman MP18 and the American-made Thomson machine gun, we borrowed the design advantages of the Browning light machine gun, through repeated verification, and after hundreds of improved designs, we finally achieved substantial results at the end of last month, and produced two batches of a total of 30 batches of test sample guns."

"The gun adopts the most mature bolt short recoil technology, and the improved fast and slow machine not only has the function of single shot and continuous shot, but also is easier to grasp in the firing frequency, and the additional safety machine avoids the defect of easy misfire. The gun has a total length of 830 mm, a weight of 3.75 kg, a barrel length of 310 mm, a reduced and hollowed out design of the butt ......"

Zeng Chaoran, who was stunned from the moment he saw this submachine gun, finally couldn't help it:

"May I ask a question, Mr. Weiss, are you mistaken? The German-made MP18 has a barrel length of only 200 mm, and the full gun length is only 820 mm, and the gun in your hand looks slightly smaller than the Bergman M18, and the heat sink is canceled, and the use of a thickened conical barrel and a novel annular column crosshair, it doesn't look like the barrel is long, how can it have a barrel length of 310 mm? ”

Weiss smiled apologetically, turned around and asked another technician to hand over a Bergmann MP18 submachine gun from Germany, and put the two guns together in detail: "General, please see, the barrel length of the new gun is obviously one-third longer than that of the Bergman MP18, you are right, due to the latest design with a slightly tapered thickened barrel, it doesn't feel very obvious when you look at it alone, and it is obvious when the two guns are compared together, isn't it?" ”

Seeing Weiss licking his beard humorously, everyone was happy, but Zeng Chaoran was not embarrassed at all, but apologized to Weiss and praised it from the bottom of his heart:

"Great! As far as I know, the German headquarters had long wanted a submachine gun with a shooting surname that could and reliably surpass the Bergman MP18, but because the war ended so quickly, everything had changed, and I think their German counterparts would be more excited than I would have seen it. ”

Weiss nodded understandingly, he knew very well in his heart that the general in front of him had served as a senior staff officer of the headquarters of the German Western Front Command in the war, and was the best commander and military theorist among all the commanders and military theorists sent to study in Germany, and he was also Xiao Yimin's sworn brother, who had extremely high prestige and an important position in the Sichuan army, so Weiss was very polite and had a good impression of Zeng Chaoran, who was unsmiling and rigorous and serious.

After everyone finished laughing, Weiss continued: "The reason why we have achieved the advantage of long barrels under the condition that the total length of the whole gun remains unchanged is because we have made two improvements: first, considering the gap between the body and arms of the Chinese [***] people and the Westerners, we have reduced the butt and crank, the length has been reduced by 60 mm, and the weight has been reduced by one-third, which is more suitable for Chinese officers and soldiers." After the finalization of the form, we will also test the retractable butt proposed by the general and the hollow butt made of steel bars, in order to meet the requirements of the mountain troops and the ship forces. ”

Speaking of this, Weiss handed the new gun to the Chinese assistant who was 1.75 meters tall next to him, and asked him to pose as holding a gun and shooting respectively, which quickly won the recognition and praise of the generals.

Weiss took back the gun and continued: "The second is the improvement of the bolt and the magazine, we have invested the most time and energy in this area, through substantial technical improvements, not only shorten the bolt recoil stroke, but also use a more concise Browning short recoil firing mechanism and integrated reinforced spring, so that the gun firing speed and stability are significantly improved, easier to repair and maintain, and the length is also shortened by 50 mm."

"The sum of the length of the two reductions was applied to the barrel of the gun, striving to achieve maximum range and accuracy, and as a result, the muzzle velocity and range of the bullet were significantly improved, and I can say without modesty that the gun's accuracy and penetration at a range of 150 meters are ahead of all similar weapons in the world, and the lethality at a range of 200 meters is twice that of the Bergman MP18."

Weiss pointed to the magazine and section sleeve of the two guns, compared them one by one, and then continued: "Please look at the design of the door of the two guns, we have moved the door of the new gun to the back and top of the magazine, and the distance between it and the annular column crosshair above the muzzle is larger, so as to obtain a longer aiming baseline; Then there is the new design of the magazine socket under the back of the section sleeve, the extended 60mm steel socket sheath is surrounded by heat-resistant bakelite to achieve better stability and more convenient refuge, and the extended socket sheath uses the latest fixed tenon, just press this round button, you can easily pull out the magazine, please see ......"

Weiss put down the Bergman MP18, picked up the new gun, pressed his fingers on the round buttons, easily took out the empty magazine, and then picked up a magazine full of thirty rounds from the table, inserted it into the socket sheath very easily, only to hear a slight and crisp metallic sound, the built-in spring piece locked the magazine steadily, and pulled the spherical bolt handle, the bolt pull sound and the sound of the bullet loading sounded pleasantly.

Zeng Chaoran was a knowledgeable person, and couldn't help but praise: "Great! The shape and surname can be very good, in addition to the hollow butt makes people feel novel, it can be said that the design of the whole gun is peaceful, very coordinated, and the most important thing is the unique creativity, as well as a major innovative design, these two points are particularly rare! ”

Xiao Yimin smiled at Weiss and said, "Let's go!" Let's try it together, as long as these sample guns shoot six magazines in a row without malfunctioning, and have the accuracy and penetration you call within 100 meters, I will immediately approve the finalization and start mass production, and I will also celebrate you and your research team! ”

The generals chimed in and followed Xiao Yimin and Weiss to the firing position.

Xiao Yimin saw Weiss standing with a gun, smiled and asked: "Normally, even if it is an MP18 imported from Germany, the barrel will not be able to stand it after firing six magazines in a row. Weiss? ”

"Haha! Not to mention six magazines, even after shooting ten magazines in a row, it is okay, we have come to the conclusion after repeated experiments, due to the use of thickened barrel and conical design, the selection of high-quality chrome steel to produce the barrel, the heat dissipation surname can be greatly improved, continuous shooting of twelve magazines has not significantly affected the shooting accuracy, in the test, usually after shooting the fifteenth magazine need to stop and wait for the barrel to dissipate, that is, to reach a high level of 450 rounds without stopping shooting, the disadvantage is that the cost is much higher. Weiss replied proudly.

"What about the unit cost?" Xiao Yimin asked with a smile.

Weiss replied: "The unit cost after mass production is about seventy-five yuan Chinese silver coins. ”

Xiao Yimin sighed slightly: "It's a little expensive, but compared to the current MP18 quotation of more than 90 yuan in Shanghai, it's quite passable, if it can really reach the level you introduced, it's definitely worth the money, and you don't have to worry about sales with an annual output of 50,000 pieces...... To be honest, I'm not willing to sell it. ”

Weiss laughed, and after obtaining Xiao Yimin's consent, he personally acted as shooters with the other five technicians.

The dense gunfire soon rang out, including Xiao Yimin, Bao Jiqing and Zeng Chaoran, more than ten generals and many officers and soldiers hurriedly looked at the target, only to see the target 50 meters away in front of the target sawdust fluttering, although not all of the six technicians have excellent marksmanship, but there is no difficulty in the short distance of 50 meters, the six people shot two boxes of bullets and none of them missed the target, this excellent performance, immediately won the applause and applause of hundreds of soldiers around.

After Weiss finished firing five magazine bullets, Xiao Yimin was worried about exploding, so he immediately ordered six guards to step forward and take the guns and continue shooting.

In the end, the six guards finished firing all the ten magazines equipped with each gun before waving their hands, and one by one they surrounded the targets that were sent quickly, inspecting the 50-meter and 100-meter targets that had been made into honeycombs, and then carefully examined the new guns, and enthusiastically discussed their feelings.

Xiao Yimin was overjoyed and praised this new gun for being an unprecedentedly good gun in every aspect, and it was definitely a world-class level.

After personally going up to test shoot the two magazines, Xiao Yimin suddenly discovered that the mystery of the hollow butt is that the center of gravity of the gun is more balanced, and the weight is reduced.

Since then, Xiao Yimin finally has his own submachine gun, and the design and technology are ahead of Europe and the United States, which is a great weapon to fully make up for the gap in medium and close range assault weapons, and will bring great help to Xiao Yimin and his army.
