Zhong Changsheng carefully fiddled with the bullet in front of him, which was redesigned according to the note given by Qin Lang. Pen Fun Pavilion www.biquge.info made some samples by hand during this time, and the effect of hitting them on soap is amazing.

"Prosperity, the bullet has been made?"

When he saw Qin Lang, Zhong Cheng jumped up suddenly, and he grabbed seven or eight bullets from that pile of bullets.

"Shao Dong, more than 20 kinds of samples have been changed, and only this one is of great use. Sharpened streamlined warhead, the mass was reduced by one gram, the cartridge was increased to forty-four millimeters, and after the warhead was shortened, the ceased action was good. After calculation, the muzzle kinetic energy is about 2,800 joules, which fully meets the design standard. ”

Qin Lang waved his hand.

"Be sure to keep it confidential, all the information is not allowed to be taken out of this house, and I will increase the number of guards again. Pick some reliable comrades and follow me to the prairie tomorrow afternoon, remembering not to show any words. ”

Zhong Changsheng was stunned for a while before a surprised expression appeared on his face.

"The young owner is talking ......."

Qin Lang shook his head slightly.

"How's the gun designed?"

Zhong Changsheng hurriedly walked to a table, opened the covered tarpaulin, and saw a rifle resting on the shelf, but there was still a big gap with the gun he imagined. It looks like a four-four mounted rifle of the Japanese Kingdom, and even the folding bayonet is exactly the same.

"This is a semi-automatic rifle of a new design with a magazine capacity of ten rounds, a gun length of eight hundred and eighty millimeters, and a bayonet of three hundred millimeters. The parts inside have been simplified and can be welded after stamping without any loss of strength. For example, this part will be faster if it is three per hour if it is used for cutting and cutting, twelve per hour for stamping and welding, and if it is on the assembly line. ”

Qin Lang took the rifle in his hand and weighed it, it was about seven pounds, which was already light in this era.

"Accuracy within 400 meters can be guaranteed, and according to your requirements, the empty gun hang-up function has been added. It's that the magazine still needs to be improved, otherwise the pressure force of the bullet will be too great. ”

After Zhong Changsheng finished speaking, he took the rifle, and he picked up a magazine containing ten rounds of ammunition from his side, but his face was blood-red, so he pressed the bullets into three shots, and the rest rolled to the side.

"Click, click."

In the end, there was really no way, so I could only press one shot at a time into the magazine.

"Young owner, try!"

With this effort, his hands swelled purple, and it seemed that he had used all the strength of his body.

Qin Lang took the rifle and fired at the target a hundred meters downstairs.

"Bang, bang, bang!"

"Ding, ding, ding!"

The target is made of thin steel sheets, and it makes a crisp sound whenever it is hit.

Zhong Changsheng kept looking at the target with a telescope, and when he saw that all the bullets were fired, he said with a smile:

"The young owner's marksmanship is just right, nine out of ten shots, and one hit the ground."

Qin Lang put down the gun in his hand with satisfaction.

"It's because you used too much force, causing the bullet to deform a little. Prosperous, the recoil of this gun is just right, solve the problem of the magazine as soon as possible, I want to produce some in small batches, so that the troops can try it out and improve it later. ”

Zhong Changsheng smiled:

"The barrel and butt can be used directly on the four-four rifle, and some internal parts can also be used, but the key part needs a stamping machine, otherwise it can only be used for precision casting or milling, if the material is sufficient, one person can produce two dollars a day."

Qin Lang was a little puzzled and said:

"Why does the magazine have so much force?"

Zhong Changsheng shook his head helplessly and said:

"Someone miscalculated the data, and as a result, the elastic steel sheet ordered did not fit, and a new batch has been ordered, and it is time to look at the schedule."

Qin Lang nodded slightly.

"Who miscalculated and found out?"

Zhong Changsheng thought about it for a moment.

"I know who it is, he is usually rough, how dare I use him in the future."

Qin Lang was silent for a moment and then asked:

"What about the submachine gun I asked you to make?"

Zhong Changsheng took out a silver submachine gun from a box next to him, but this time it was not out of shape, exactly as he thought.

"Young owner, who designed this? I've never seen such a simple firearm, something that can be produced in a small workshop. At first, a few of my classmates laughed at it, saying that there are ghosts when you hit it loudly. As a result, a few shuttles went out, and no one dared to speak. ”

Qin Lang asked seemingly unintentionally:

"How many people know about this gun?"

Zhong Changsheng thought for a moment and replied:

"Even there are three of us, and the other two classmates are talents carefully cultivated by Mr., and this time they also went to the grassland together."

Qin Lang secretly breathed a sigh of relief. He took out a magazine from the box and inserted it into the gun, went to the window and pulled the trigger on the target thirty meters below.

"Bang bang bang!"

A silencer tube has been added to the gun, so the sound is not very loud.

"Ding, ding, ding!"

The sound of the rake kept ringing, but the bullet was empty in an instant.

Qin Lang looked at the green smoke at the muzzle of the gun and asked:

"How many magazines will the barrel overheat?"

Zhong Changsheng says:

"If you shoot five magazines in a row, you have to cool down for 10 minutes, otherwise it will overheat. Because of the muffler, you can't install the brake you designed, or the recoil will be smaller. Semi-automatic, we also designed the gun grenade holder ....... ”

Qin Lang waved his hand.

"Can such a weapon be designed?"

Zhong Changsheng saw the sketch in front of him and couldn't close his mouth again.

"The caliber is forty millimeters, the firing range is about four hundred meters, single shot! The structure of this gun is like an old-fashioned shotgun, how could I not have thought of it? It's the process of the barrel and the grenade, and the process is not a problem! Compared to a grenade, it ....... ”

Lin Wei asked herself to persuade Zhong Changsheng to have a good rest, but in the end, he added another burden to it, and it seemed that he had to forget to sleep and eat again.

When Qin Lang walked out of the house, he saw the captain of the security team making a gesture to himself and followed him to a room.

"Commander, someone here has already paid attention, looking at that sneaky appearance, nine times out of ten it is a widow. Several of Mr. Liu's disciples also had unclear relationships with those Japanese women. Isn't it....... ”

Looking at the gesture of slashing down, Qin Lang shook his head.

"The Tao is not the same, let's send those gifts away, even if it is for the sake of Mr. Liu's face. You can't bring anything with you, and each person will be given a settling-in allowance of fifty oceans. ”

"Yes!"

The captain of the guard immediately replied.

Qin Lang thought for a moment and said:

"If we take such a move, those Japanese people will definitely not give up, and let the third and fourth special operations teams in Tianjin stand by to prevent the Japanese dogs from jumping off the wall in a hurry."

The captain of the guard whispered again:

"Commander, I suspect that the guy who miscalculated the elastic steel sheet, what preparations have he made, he has been wandering around the public concession recently, is it to find out his details?"

Qin Lang nodded.

"Let's go in the evening, and if he has any intentions, then we must not be merciful."
