In fact, early in the morning, Tu Qianjun thought about changing the bullet caliber of the Tiger assault rifle to a small-caliber 5.×42 ammunition! It is the type of gun he used in later generations - the Type 7 automatic rifle!

Many people know about the Type 81 automatic rifle, but most people don't know about the Type 87.

In the 70s of the 20th century, l was developing a new one. And new ammunition requires new rifles to work with it.

As a result, the development of new ammunition was greatly delayed, but it was necessary to ensure that a new weapon could be used in the army in the early 190s, and as a result, the new weapon was still the Type 1 rifle that used the 7.62×39mm intermediate power rifle cartridge, and it was not widely equipped until the end of the 0s to replace the outdated Type 56 automatic rifle.

However, there are concerns about whether the new bullet gun system is really safe. Therefore, it was necessary to add new bullets to the relatively mature system at that time.

In 194, the first DB7 rifle cartridges were finally ready for mass production - and soon after, there were a number of Type 1 rifles that were modified in special editions that used this new model. That is, the Type 7 automatic rifle.

The main purpose of this weapon was to convert the barrel caliber from 7.62 mm to 5.mm, but this rifle was only produced for a short period of time. Tests have shown that the newly designed bullet has a higher superiority than the 7.62×39 mm.

In 19, the firearm of this system that fired DB7 rifle rounds was designated the Type 7 automatic rifle.

The Type 7 rifle was produced only for an extremely short period of time, and it was not long before it was completely discontinued. The main reason for the discontinuation of production was the start of the design and production of a more competitive Type 95 rifle with a stockless structure.

The Type 7 Automatic Rifle is similar to the Type 1 in terms of structure, except that it has been replaced by an intermediate-powered bullet instead of a projectile. And 7 uses a lot of new materials. In fact, to put it bluntly, the 7 type is the 1 type of the enhanced version.

Like the Type 95 and Type 03, it uses a 5.×42mm DB7 bullet developed in China. However, what is even less known is that although this rifle is not equipped, it has become a favorite of the special forces! After Tu Qianjun finished explaining, he took a deep breath and smiled at these engineers: "I hope you will perfect this gun as soon as possible and make the first prototype gun." ”

Everyone couldn't help but nod when they heard this, and then Tu Qianjun put down the drawings and left the research and development office directly. The R&D office is located in a secluded mountainous area outside the city of Mukden, and a series of R&D equipment and precision machine tools are transported from a hollowed-out cave.

There is also a team of dozens of technicians working with this office to make guns, and there is a reinforced battalion of the Guard Regiment of the General Headquarters of the Wehrmacht stationed here! Only three miles outside of this mountainous area, there is a regiment of the Mukden garrison stationed!

Therefore, the guards here are not unstrict! The engineers and technicians who were selected were all transferred to this R&D office after Tu Qianjun investigated their families through the North American Zhigong Court and confirmed that there was no problem.

In order to worry about his gun architecture being leaked, at least for the time being, Tu Qianjun does not want his gun design to be leaked. The complete version of the Tiger assault rifle, that is, the later Type 7, as its former user, Tu Qianjun knew how big the impact it would bring in this era full of single-shot rifles!

Therefore, Tu Qianjun did not want this kind of gun to be used in the battle against his own troops. Even before the outbreak of World War II. None of him will give the blueprints of such guns to the Americans.

After getting out of this cave, Tu Qianjun left the R&D center after going through a series of checkpoints. returned to Fengtian City, and then he summoned Jia Xiaohou, the former director of the Fengtian Arsenal who was now in charge of the Fengtian Arsenal and was rushed back from Yang Hucheng, Shaanxi!

This Jia Xiaohou is not a simple character! This person can be called one of the founders of China's modern weapons science and technology industry!

Jia Xiaohou, the word Bao. A native of Huxian County, Shaanxi. After the Xinhai Revolution in 1911, he joined the China League. He has studied in Japan, the United States and Germany funded by the government of the Republic of China, and is proficient in weapons manufacturing, bomb manufacturing, blasting and other professional skills. Later, he served as the director of arsenals in Manchuria, Shaanxi, Hubei, Gansu, Guangdong, Guangxi and other places!

He studied in Japan, the United States and Germany, and was not only proficient in the three Chinese languages, but also familiar with metallurgy and weapons manufacturing. He improved the Type 1924 Maxim heavy machine gun and added hydration bladders. The Krupfield artillery was improved, and the firing range was increased from 6000 to 9000 meters. The imitation Czech 7.9mm light machine gun he designed was designated as a standard machine gun by the Ordnance Administration.

He invented and successfully test-fired two-wing, three-wing, and four-wing rocket artillery shells, with a range of 4,000 meters, which greatly deterred Japan's bombing of Xi'an at that time.

After the successful nuclear test of the United States. When Jia Xiaohou was working part-time in the physics and chemistry class at Cuihua Mountain in the Qinling Mountains at the Shaanxi Anti-Japanese Cadre Training School, he boldly predicted: No matter how bold the Japanese are, they are afraid of the atomic bomb. If our country had an atomic bomb, the Japanese would not have dared to be so rampant.

During this period, he purchased 100 books on atomic energy and nuclear energy through various channels, and informed Hu Zongnan, Dong Zhao, Zhu Shaozhou, and other senior generals of the state government of his ideas. It's a pity that they all think. The research and manufacture of the atomic bomb takes a long time, the cost is high, and the technology is strong, and the fear is beyond the reach.

What is even more regrettable is that after the liberation, this scientist who insisted on staying on the mainland and even cooperated with Wu Hao was brutally suppressed. He was shot in '51. So much so that when the country was preparing to develop an atomic bomb, I remembered this scientist and planned to transfer him, but I found that he had been shot several years earlier. At that time, everyone couldn't help but feel sorry.

Now, this scientist who had participated in the Xinhai Revolution rushed to the Northeast in anger after 918, and Mao recommended himself to find Yan Zhengqing and asked to be the director of the Fengtian Arsenal! Of course, Yan Zhengqing couldn't ask for such a talent, and even in order for Jia Xiaohou to play a greater role, Yan Zhengqing also arranged for Jia Xiaohou to go to the Institute of Engineering of Dongda as a professor!

By the way, I translated those engineering works in the original language. Jia Xiaohou originally went to the Northeast because of the attitude of the government of the 918 and the Sea Incident, but now he actually met people like Yan Zhengqing who had a similar experience to him but had higher knowledge than him.

And he also had the opportunity to teach students, so he naturally happily stayed.

"Commander, you have something to do with me?!" Jia Xiaohou has the temperament of most scientists of this era. That is, to speak directly and to do things urgently! Don't like others to waste his time. To be continued
