With sophisticated bullets, then there must be a rifle that fires this kind of bullet, Xu Jun does not have many options, after all, until the end of World War II, there was no automatic rifle with excellent performance. From the beginning, Xu Jun wanted an automatic rifle, not an assault rifle that fired medium-power bullets.

Now because of Xu Jun's decision, the famous MP44 in history has disappeared, and the supporting German 7.92x33mm short bullet will not appear again, which will inevitably affect the invention of the Soviet Union's 7.62x39 bullet, and the Soviets can only use it as a reference for the 7.62NATO bullet, which means that the AK series will be delayed for a long time, or even not designed at all, unless the history of Hugo Schmeiser repeats itself, which now seems to be somewhat unlikely.

The weapon chosen by the head of Xu Da was the first standard automatic rifle equipped by the Federal Republic of Germany after the re-establishment of the Wehrmacht after the war, the famous G3 automatic rifle.

To say that the G3 rifle was developed in the early fifties, in fact, it is beyond the scope of Xu Jun's database, a full set of drawings for the Type 50 automatic rifle, and more importantly, Xu Jun once disassembled and assembled this rifle by himself.

That private military museum not only houses World War II equipment, but also a lot of army equipment from the division of East and West Germany, including the famous G3 rifle. As the main technician of the museum, Xu Jun once disassembled and maintained the entire G3 gun family (had a lot of ≦≧fun at that time), and knew the parts and structure inside, and he could even draw a gun structure diagram with his bare hands.

At that time, Xu Jun would never have thought that this rifle would become his "invention" in another time and space.

The semi-rigid roller bolt bolt is not a technical secret, it is only a few improvements on the roller bolt, the latter is the MG42, now called the MG40 machine gun locking form, this structure can effectively reduce the recoil generated by the bolt.

The semi-rigid roller bolt bolt is a new type of locking structure developed on the basis of the roller locking structure, which was invented by Ludweg Grimler, the gunsmith of the Mauser company, and developed the last assault rifle Stg45 in Nazi Germany on this basis, and it should be pointed out that this weapon still fires 7.92 short rounds.

At the end of the war, Grimler was captured by the Allies, first assembled the Stg45 for the British in a Dutch prisoner of war camp, and then sent to France to begin the development of assault rifles for the French.

At that time, the French Mulhouse mechanical studio was developing a new assault rifle for the French Army, the technical prototype was the Stg45, and the French who did not change actually asked for this new automatic rifle to develop three models that fired ammunition of different calibers, so that the Ministry of Defense could compare, one was Germany's 7.92 short bullet, the other was France's own research and development of 7.65x35mm intermediate ammunition, and the third was 7.5mm carbine bullet.

As a result, Grimler came up with a design that pleased the French, an automatic rifle with a tripod and a folding stock, which was quite good for the time. The problem was that at this time France was suppressing the uprising in French Indochina, military spending was already beyond its means, and the North Atlantic Treaty Organization was being established, and the French army did not have a very strong need for new weapons, and the French finally canceled this weapons project.

However, the design of the CEAMM50 model has been completed, and this weapon is now very similar to the G3 rifle, with only minor differences in the heat sink and magazine.

Grimler lost his job when the project was discontinued, but he soon received an invitation from Spain to design a standard rifle for Spain. Grimler immediately left for Spain, where he was hired by the Spanish Agency for Technology and Special Materials, a government agency specializing in the development of light weapons.

Grimele brought with him CEAMM50 design drawings from France (known as the AME49 in Spain), on the basis of which he developed the Sethmai rifle that fired 7.62x51mm rounds. It's just that at this time Spain was using reduced ammunition, and it was not until the appearance of the G3 that it was improved to a model that could fire full ammunition.

Subsequently, the Federal Republic of Germany signed a contract with Spain for the purchase of weapons, and in addition to importing a batch of these rifles, it was also required that the German-designed rifle be produced in Germany. Eventually, Grimmler returned to his home country with the Seitmai rifle and further refined it at the renowned H&K (Black Kohler & Koch) company, which was finally finalized as the G3 automatic rifle in 1956.

But now history has changed, and this rifle will appear in the world sixteen years earlier, maybe fifteen years, depending on how efficient Mauser is.

The Mauser company had become numb to the Führer's endless inventions, and they were even more confident than the Führer, and had no doubts about the feasibility of the design, and now a bunch of Mauser factory designers were working on a second design of the structural drawings, including Ludwig, the original designer of the gun. Grimler.

Xu Jun only drew the design sketches of this weapon, as well as the structural details and technical parameters, and the rest of the work and production drawings need to be drawn by the technicians themselves. However, Xu Jun had already come up with the most critical drawings of the receiver and bolt, and the rest of the work was hardly difficult for this group of experts. Because the data heads who need it are already very clear, they just need to add some details to it.

The gunsmiths at the Mauser factory made the metal parts directly by hand, and carried out a series of mechanical tests, which showed that the Führer's design was excellent, and the bolt operated smoothly.

The Mauser technicians were completely captivated by the weapon, not only because it was designed by the Führer, but also because this automatic mode opened the door to a new world for them.

In addition to this roller structure, can other modes be adopted? Does a deflection latching work? Is it okay to have a semi-free bolt? Many people began to devote themselves to the design of automatic weapons.

While trying to understand this advanced design, the Mauser factory began to build special jigs and molds for this weapon, making initial preparations for the eventual establishment of a production line.

This weapon uses a large number of stamping parts and castings, there are not many parts that need to be manually cut, it can be expected that the production man-hours consumed are quite small, and the cost is easy to grasp, and it can be basically controlled at about 50 marks, according to the purchase price of 70 marks, Mauser can get 40 percent of the profit, although it does not seem much, but it can't stand it, if according to the Führer's plan, the first batch is ready to purchase 200,000 pieces, And the Führer's ultimate goal was to completely replace the original Mauser rifle with this rifle, which would be a big business involving tens of millions of marks.

This rifle was only part of the Führer's rearmament program, which also used this locking mechanism as a basis to develop a new submachine gun to replace the original MP38/40 series.

The new submachine gun uses 9mm Bellabloom bullets with a front handguard and a pull-out folding stock, as well as a curved magazine with a capacity of thirty rounds, and you guessed it, this is the future B31 that will scare terrorists... No! It was supposed to be an MP5 submachine gun.
