As soon as Xu Jianguo appeared in the yard, Xiao Hei ran out from the three girls' room and rubbed his trouser leg with his big head.
Patting its big head, Xu Jianguo took out a large piece of duck leg from the space and threw it to it, then walked into the house.
After looking at Wen Sitian who was still sleeping soundly, he changed into his military uniform and took out the breakfast prepared by Du Yu from the space.
After having breakfast and adding coal to the pit, Xu Jianguo left home and appeared at the corner of the workshop of the 523 Institute through the space portal.
He opened the padlock and walked into the house. Since Xu Fei and Xu Yang were currently in Hong Kong Island, he did not arrange for anyone to be outside today.
He took out the barrel and receiver that had been processed yesterday from the space, turned on the power, and continued to work on making the gun.
…
In the blink of an eye, half a month had passed. As Xu Jianguo became more and more proficient in the operation, he processed the parts of the two guns one by one.
The last component Xu Jianguo needs to make today is also the most important component on the two guns, the sight.
He put on gloves, took out a round piece of optical glass from a large wooden box, and then began the preliminary processing according to the drawing in his mind.
The processes of cutting, polishing, metal wire drawing, metal wire inlaying, optical glass patching, sleeve installation, damping adjustment, etc. are completed in one go.
Finally, before leaving get off work, I managed to make two white light scopes.
One is for Type 81 rifle and the other is an eight-fold scope for sniper rifle.
Looking at the gun parts on the table, Xu Jianguo felt a sense of accomplishment.
With a series of clicking sounds, two new guns with a metallic luster appeared on the table.
Xu Jianguo picked up the Type 81 rifle and weighed it in his hand. He felt that it was much lighter than the Type 56 and the overall workmanship was much better. However, this was polished by him by hand. If it is adopted in the future and put into mass production, it will definitely not be possible to achieve this level of craftsmanship.
The Type 81 rifle manufactured by Xu Jianguo has optimized the notch and peep sights, allowing accurate shooting even without optical sights.
At the same time, an inner cavity design is added to the handguard to ensure that the handguard will not become hot after continuous shooting.
In order to facilitate the use of the under-slung grenade launcher, Xu Jianguo added a new rail design under the handguard in front of the trigger guard. You only need to align the under-slung grenade launcher with the rail and push it in. After locking it with the retaining spring, it can be hung firmly under the gun and become one with the entire gun.
In addition, Xu Jianguo also optimized the design of the ejection mechanism of the Type 81 rifle, so that the ejection direction of the bullet is always maintained at 45° to the right front of the gun body during shooting, avoiding the impact of hot shells on comrades around him during team combat.
The lever that controls the rate of fire selector has been moved back to the top of the grip on the left side of the gun. The gun holder can quickly switch between single-shot, three-shot and continuous fire modes with his thumb. This is an ergonomic design that can effectively improve the soldier's reaction speed when dealing with emergencies.
The empty chamber lock still uses the original design of the Type 81 rifle, but Xu Jianguo specially added a quick release button to make it more convenient for soldiers to operate. After replacing the new magazine, the soldier only needs to press the button to release it, push the bullets in the new magazine into the barrel, and directly pull the trigger to complete the shooting, further improving the continuity of shooting.
Putting down the Type 81 rifle, Xu Jianguo picked up the AWM sniper rifle on the table, then pushed the eight-fold scope next to it into the guide rail. With a crisp click, the scope was installed in place.
He raised his sniper rifle, looked out through the scope, and aimed at a target paper hanging on the wall. Then he stretched out his right hand and slightly turned a knob on the sight to align the cross in the sight with the gun's built-in sight.
He had never learned how to calibrate firearms, so he could only debug it according to his own ideas. He had no bullets with him, so he couldn't conduct live-fire shooting.
At the beginning, Ma Guoliang had specifically instructed him that he was only allowed to make guns and not bullets, and that the guns and bullets must be kept separate.
Xu Jianguo understood this very well. After all, guns are dangerous goods, and since the founding of Longxia State, the control of guns and ammunition has always been under high pressure. Simply put, it is a high-voltage line, and anyone who touches it will die.
Xu Jianguo did not make any optimization adjustments to this AWM sniper rifle, and still used the most original design concept, but in terms of bullet choice, he used 7.62*67mm high-powered sniper bullet.
So far, all the design and manufacturing work for the two new firearms has been completed. Next, Xu Jianguo needs to hand over the design drawings of the grenade and sniper bullets to Ma Guoliang, who will coordinate the manufacturing of the bullets.
Putting down the sniper rifle in his hand, Xu Jianguo came to the large wooden box in the corner, put away the unused optical glass inside, then took out the tools, disassembled the wooden box, and rebuilt two wooden boxes according to the size of the two new guns.
The two guns were disassembled, the parts were wrapped with cotton cloth, and placed in a wooden box. Finally, everything was put into the space.
Just as he finished all this, the bell for the end of get off work rang outside. Xu Jianguo walked to the window and pulled open the curtains. He had asked Wen Sitian to sew these for him before, just to prevent people from following him outside.
Because Xu Fei and Xu Yang have been busy with patent registration in Hong Kong Island recently, Xu Yan and Xu Li are in Japan, and Fu Bo and Du Yu also have their own jobs, so he has no choice but to use the most primitive method of curtains.
After turning off the lights and the power, and locking the workshop door, he pushed out a bicycle from the corner. This was a bicycle that Ma Guoliang had sent to him earlier, saying that it would be convenient for him to use on his way to and from get off work.
Xu Jianguo rode very fast and returned home in just twenty minutes. However, as soon as he entered the yard, he found that the atmosphere at home was a little wrong.
Normally, whenever the three girls heard the bicycle bell, they would run out of the house to greet him, but today no one came out.
He pushed his bicycle to the corner, opened the door and walked in.
The whole family was in the living room. Wen Sitian was sitting on the sofa in a daze, Xiao Hei was lying at her feet, and the three girls were lying on the ground playing cards absent-mindedly.
Although this scene seems normal, Xu Jianguo has lived with them for so long, how could he not notice that today, the three children, the adult and the child, all seem to have something on their minds.
