The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 41, Gunsmithing

In the office of the Firearms Research Institute of the 626 Factory, before Wang Duoyu finished speaking, the eyes of Lin Dehong, Hao Guoliang, Ge Jianshe and others had already fallen on the firearm blueprint in his hand.

This gun is an improved version of the M4A1 carbine. The bullet caliber and other aspects have been improved. Of course, the magazine has also been improved. It is relatively larger, but it is acceptable. In terms of weight, we can only make improvements in the gun material.

"Are you sure this kind of gun is really good?"

After reading it, Ge Jianshe raised his own doubts: "The design drawings look absolutely perfect, but designing a firearm is not that simple. According to my country's firearms quality assurance system, a gun's overall performance includes six aspects: reliability, accuracy, durability, stability, maneuverability, and economy. How many of these do you think your gun can meet?"

As the saying goes, an expert can tell whether something is good or not just by looking at it.

Although Ge Jianshe's attitude towards Wang Duoyu was not very good and he also found many faults in the firearms designed by the latter, what he said was not wrong, and it also showed that he was indeed capable.

"Team Leader Ge must have seen the AK47, right? The gun I designed and improved has much less recoil than the AK47. Whether it's single-shot or continuous shooting, the recoil is definitely better than the AK47."

Wang Duoyu laughed and continued:

"Let's not talk about the Type 63 automatic rifle, it has been eliminated. But even if it hadn't been eliminated, when it was first designed, its performance was not as good as the one I'm designing now."

"Let's not even talk about the accuracy of burst fire. I'll just talk about the accuracy of continuous fire. It's definitely much better than the Type 47 automatic rifle, AK, and other firearms."

"As for durability, stability, and economy, I can currently answer your questions about stability and economy. Regarding stability, we can test the guns after they're manufactured. As for economy, we only need to improve the materials used in the guns. It's definitely cheaper than the Type 63 automatic rifle."

The AK47 is a world-famous gun, and the Type 47 automatic rifle is a light weapon imitated from the AK, so people like Ge Jianshe all understand this gun.

The Type 63 automatic rifle is an improved version of the Type 56 rifle. However, Wang Duoyu said that the rifle he shot was even better than the Type 63 and other rifles in terms of economy, stability and durability.

Wow, Wang Duoyu is like a newborn calf who is not afraid of tigers. He directly uses such a gun to challenge AK47, Type family bucket, Type automatic rifle and other series of guns?
"Haha, then I'll wait and see."

Ge Jianshe chuckled, his eyes filled with intriguing thoughts.

But at this time, Hao Guoliang nodded calmly and asked Wang Duoyu in detail about the various data of the gun, especially the design and use of materials. After asking, he took the initiative to say:
"Okay, no problem, but it's already late today, and we still need time to prepare the materials. Besides, this gun is so excellent, it won't be too late to start the trial production tomorrow."

That night, Wang Duoyu was arranged to have a simple meal and stay overnight in the dormitory within the 626 Factory. The next day, the trial production officially began.

Factory 626 was a arsenal in Northeast China. Besides manufacturing and testing small batches of improved firearms designed by the Firearms Research Institute, it was primarily responsible for production. Whether it was the Korean Peninsula War over twenty years ago or the Plateau War a dozen or twenty years ago, Factory 626 operated at full capacity, with production capacity exceeding 1,200 Type 56 semi-automatic rifles per day, or 400,000 rifles per year.

The output was very large, but no one actually knew how many guns were produced in the five or six family barrels, because the army's size at its peak exceeded six million, so it would only require six million guns.

But what about the even larger militia? These also needed to be equipped with weapons. As far as Wang Duoyu knew, his nephew Wang Xiangdong had to train once a year, each time for ten days, and all with live ammunition. The training for cadres and instructors was thirty days, also with live ammunition.

In any case, the total stock is definitely more than tens of millions of guns, because this can be inferred based on data: in the future, when we export light weapons, we will export them directly by weight.

In the Moscow-style brick-and-wood structure factory building, in the dimly lit stamping workshop, Wang Duoyu and others were all here. When they walked in, Wang Duoyu couldn't help but frowned. Is this the famous 626 Factory?

The stamping machine was making a very loud noise. It should be producing the Type 56 family barrel of firearms at this moment. However, Wang Duoyu knew something was wrong after just one look, because it was not producing the Type 56 family barrel, but rather it seemed like it was producing the Type 63 automatic rifle.

Hao Guoliang and others were very embarrassed. After all, the Type 63 automatic rifle had been temporarily withdrawn, but they were still producing this gun here. Wasn't this a joke?

"Why are they still producing the Type 63 automatic rifle? Didn't they say they were going to stop producing it?"

"Well, we still have some orders that we haven't finished yet, so we're rushing to finish them. If we don't finish them, we won't get the funding."

The workshop director's explanation was very forced. The face of the factory leader Hao Guoliang was very dark. If his eyes could kill, the workshop director would have been cut into pieces.

Wang Duoyu's eyes fell on the machine tools arranged on both sides of the workshop. There seemed to be more than 40 punching machines, hydraulic presses, etc. of various models. The paint on most of the fixed desktop punching machines was still intact, and a few were mottled and faded, indicating that the workshop workers had done a good job in protecting these equipment.

The qualified steel plates sent from the steel plant were put into the punch press mold by the staff. After the machine was started, there was a loud bang and it quickly turned into a pile of formed metal parts.

A gun consists of an automatic mechanism and a firing mechanism. The former includes the barrel, barrel cover, connecting seat, recoil spring, recoil spring guide rod, bolt assembly, etc., among which the barrel and recoil spring are the core components.

The Type 63 automatic rifle is divided into single-shot and continuous shooting modes, so the firing mechanism consists of a bolt, firing pin, firing pin spring, safety device, rate of fire selector, etc.

However, the Type 63 automatic rifle has a very big problem: the receiver cover flies off when firing, and flames spray backwards after firing. The cause of this problem is that the receiver is not sealed enough.

Then why could Wang Duoyu tell at a glance that this was the production of Type 63 automatic rifles?
