After Bai Yi finished saying his plan, the people around him couldn't help but be quiet, and they all looked at the notebook that had been written by Bai Yi with wide eyes, until after a while, the sound of whispering discussions sounded, no way, Bai Yi's plan just now was really a bit unbelievable.

In particular, the bolt offset locking mechanism it uses is not absent in their memory, but most of them are used in heavy firearms above the light machine gun, for example, the ZB-26 light machine gun, which is commonly used by both the enemy and the enemy, is a typical bolt offset locking mechanism.

The structure is very simple, only two complete metal workpieces are needed to complete the machining, but this seemingly simple mechanism has a complex matching.

For example, the bolt frame, for example, the receiver, and the long air duct, after a long discussion, finally someone couldn't help but open his mouth: "Chief Baike, the bolt in your plan is the same principle as the Czech ZB-26 light machine gun, and the structure is simpler than the rotary locking type.

But the problem is that it is only simple on the bolt, the frame and receiver are not simplified, but more complicated, I once copied the ZB-26 light machine gun, the machining man-hours required are quite large, especially the machining of the receiver, which is made of a complete metal workpiece with a machine tool as a whole, not to mention time-consuming and labor-intensive, and the scrap rate is also quite high......

The person who spoke had served as a team leader in the arsenal of the Nationalist Government during the Anti-Japanese War, and his other identity was the head of the underground party organization of the factory, but due to the betrayal of the traitor, his identity was exposed, and he had to return to the base area, and after the victory of the Anti-Japanese War, he went to the northeast with the army.

Because he had learned first-hand technology in the enemy's arsenal, after the Baiyun Factory was captured by our army, he was sent to the Baiyun Factory as a technical backbone, and after the automatic firearm was officially launched, he also joined in to participate in the development, because of this, when he saw the bolt offset locking mechanism in Bai Yi's plan, he couldn't help but be a little worried while being familiar, because he was very aware of the complexity of this structure in the processing process.

There were a few people present who had similar experiences, and they all nodded in agreement, and even Chen Yaoyang and Wang Dehua, who were the first to look forward to Bai Yi, couldn't help frowning, no way, the classic ZB-26 light machine gun is really known to everyone.

Especially for people like them who understand technology, the kind of casing that uses a whole piece of metal to cut directly is simply a nightmare in production, and there is no way that its fineness and operability are too demanding, and because of this, although the national government has a full set of drawings in its hands, and the reproduction is also full of strength, but its output still cannot come up, and its root is here.

Bai Yi is naturally well aware of the advantages and disadvantages of the ZB-26 light machine gun, and it is undeniable that the ZB-26 light machine gun, which uses an offset locking mechanism, has outrageous reliability, and can shoot without hindrance in any environment, and is indeed a good partner on the battlefield for soldiers.

However, this excellent firearm on the battlefield is extremely cumbersome in terms of production and processing due to the initial design, but this is also a helpless thing, although the Czech Republic is not a big country, it can be said that it is also a technologically developed industrial country, and this degree of machining is nothing to them.

However, it was quite a big problem for China, which was industrially backward, and it was precisely because of this that in the middle and late stages of the War of Resistance Against Japanese Aggression, because the production of imitation ZB-26 light machine guns could not keep up with the huge consumption, the Nationalist Government could only purchase a batch of ZB-26 light machine guns from Canada through the concession treaty between the allies, which barely supported the victory of the War of Resistance Against Japan.

Bai Yi, who had disassembled the ZB-26 light machine gun in the classroom of his previous life, and had disassembled it countless times, was familiar with this point, and because of this, it was impossible for him to follow the old path of the ZB-26 light machine gun, because he still had a simpler and more efficient way, otherwise he would not have made this plan public!

"The air duct of the ZB-26 light machine gun is below, and then the bolt frame is pushed to move from the bottom to achieve the opening and closing lock, in order to ensure the effective movement of the bolt frame, the groove design in the receiver is indeed cumbersome, and this is also the processing difficulty of the gun, and my plan is ......"

Facing the puzzled eyes of everyone in the audience, Bai Yi picked up the notebook again, and then quickly drew a few strokes on the previous sketch with a pencil, and then drew a circle in one place, and then dotted it with a pen: "The air duct is not located under the barrel of the gun in the usual way of Czech or American firearms, but above the barrel.

This brings two benefits, namely that the kinematics in the receiver can be greatly simplified, and secondly, and most importantly, when the bolt frame is moved upward, it will be level with the aiming baseline, so that a stable and continuous locking structure can be achieved with only a few simple grooves and a bolt arrest iron in a few clicks.

Of course, I dare to do this, but also based on our progress in ammunition, you must know that the ZB-26 light machine gun uses 7.92mm full-power rounds, and our new gun is ready to use a new intermediate power bullet, and we have achieved remarkable results in this regard.

In particular, the newly developed 6.5*42mm bullet, in terms of reliability, range, accuracy and power, is much better than the previous 6.5mm ammunition modified with the American M1 ordinary bullet eggshell, to be honest, if there is no appearance of this ammunition, I would not dare to engage in such an automatic rifle! ”

Bai Yi's last sentence is not an exaggeration at all, there is an unwritten rule in the field of firearms development, that is, what bullets are there, what guns are made, and Baiyun Factory has been at the forefront of the times in this field since Bai Yi proposed the new concept of intermediate power bullets.

In particular, the technical group with Chen Yaoyang and Wang Dehua as the core has not stopped researching the intermediate power bomb, and with Bai Yi's guidance from time to time, the results of this ammunition technical group can be said to be not small, that is, after using the Japanese 6.5*50mm full-power bullet warhead combined with the American point 30M1 ordinary bullet shell to form a simple intermediate power bullet.

In the end, in order to simplify logistics and facilitate immediate production, this group chose the magic modification scheme of the 6.5*50mm pointed bullet used in the 38 cover with mature technology in China:

That is, the 6.5mm pointed warhead is selected, and a section of the original bullet case is intercepted, and after reassembly, the 6.5*42mm intermediate power bullet mentioned by Bai Yi is formed......
