My son-in-law is engaged in military industry, all dogs in the village are equipped with guns

Chapter 40: The Real Way Forward, Human-Machine Efficiency!

Everyone was ordered to act, Li Fu took Qian Gou to assemble a new sample gun, and Qi He took Qian Siyai at the factory gate waiting for the special police team to deliver bullets or something.

As for Zhang Jianguo, he walked with Qi Wei to the bomb shelter behind the factory.

This is where the military factory director’s office, warehouse, and drawings and other confidential materials are stored.

On the table was a huge drawing, which Zhang Jianguo and Li Fu had drawn overnight before, and it was enlarged strictly according to the size of Qi Wei’s drawing.

On this three-view view, all the structures and parts of the Type 87 rifle are delicate, and the size is also strict to 0.1 wire, that is, 0.01 mm.

This accuracy is already the highest level that the seventh workshop can achieve. Smaller units than this, not even vernier calipers.

In fact, the processing of the seventh workshop can not reach the accuracy of 0.1 filament at all, and most of the errors are more than 0.5 filament. But that’s enough for the Type 87.

Zhang Jianguo’s gaze swept over the drawing worriedly, he was now extremely familiar with this drawing, and he could report the parameters on it almost with his eyes closed.

“Qi Wei, how do you plan to change this drawing?” He hesitated.

“I think this drawing can now be described as perfect. Rashly changing it is likely to put us into an endless loop. ”

“Moreover, even if a part is changed, the relevant testing and supporting process modification can not be completed in five days.”

Qi Wei nodded.

Zhang Jianguo is right, this drawing is given by the system, and the system gives the most complete and mature drawing, without any flaws.

In fact, the name of this drawing should not be called Type 87, its real name should be 87A, that is, the final improvement of Type 87, complete body.

Qi Wei did not expect that he would be able to modify the mature Type 87 in five days, which was impossible, not to mention that he was just a military fan, even an expert in small arms.

“Don’t worry, the part I’m going to modify doesn’t involve the key position of the receiver. Instead, it focused mainly on the butt, handguards, and the ruler section at the top of the receiver. ”

“How to change it?” Zhang Jianguo looked at the drawings suspiciously, he didn’t know how much room for change in these positions.

If it was just to change the shape and length of the butt, as well as change the quality of the protective wood, Qi Wei would not need to be so solemn.

“First of all, let’s talk about the butt.” Qi Wei pointed to the position of the butt of the drawing, which was a cane-type butt very similar to the AK.

“I need you to change this butt to a straight line,” he drew a rough shape on the drawing with a pencil, “can you read it?” ”

“Why did you change that?” Zhang Jianguo tilted his head and looked at the shape, which was simple, but inexplicably very comfortable, with an industrial beauty.

“Don’t you feel that our butt is actually a little too long?” Qi Wei smiled and spoke.

“You mean, change to a folding butt?” Zhang Jianguo came to his senses and looked at Qi Wei in surprise.

The folding stock is the latest technology in Longguo, and I heard that the R&D plant of the 81 bar is experimenting with the folding stock version of the 81 bar.

“No,” Qi Wei shook his head, “what I’m going to change is the telescopic butt!” ”

“Telescopic butt?” Zhang Jianguo chewed this term, he faintly had a feeling of opening the pattern, but what it was, he couldn’t capture it now.

However, Qi Wei did not give Zhang Jianguo much time.

Qi Wei’s fingers moved forward along the butt of the gun to the upper part of the receiver, where there was a washboard-like section.

“You asked me before what this thing is, and I told you, it’s called a guide.” Qi Wei clicked twice on the washboard.

“Yes, you said at the time, what is it called a rail.” Zhang Jianguo nodded, although he still made it, but did not find the role of the washboard.

“Forget that name.” Qi Wei’s expression moved, and he was a little embarrassed. Picardini rails came out in the 90s, and before that it didn’t exist.

“I said that name casually, it should be called modular rail.” He sighed.

“Modular, rail?” Zhang Jianguo repeated this awkward name.

“You don’t care what it’s called,” Qi Wei jumped directly over the part, “all you need to do is modify the position of the aiming caliper and move it to the back of the receiver.” Then extend the rails to cover the entire receiver and even the front handguard! ”

“And the front handguard is the third part you want to modify.”

Qi Wei’s pencil moved to the gripping part in front of the receiver: “The front handguard needs to be semi-hollowed, and the upper edge is level with the receiver and integrated with the guide. In addition, the lower edge of the front handguard also needs to be added with rails. ”

Zhang Jianguo watched Qi Wei’s pencil sketch on the drawing, and a front handguard that was completely different from the AK series and even different from most rifles appeared on the drawing.

He felt a light in his mind at this time, and this light began to get brighter and brighter, but what it was, he couldn’t figure it out.

Zhang Jianguo carefully looked at the drawings in front of him, although the part outlined by Qi Wei was very casual, and there were only a few strokes, but it was these few strokes that made the entire gun have a earth-shaking change.

It is an extremely prominent industrial beauty, and even has a bit of sci-fi atmosphere.

“Is there any special point in doing this?” He looked at the sketch on the drawing and spoke absently.

“Of course there is. This is where I think the new generation of rifles is headed. Qi Wei had an inscrutable smile on his face.

“And this direction, I call it, human-machine efficiency!”
