On the morning of September 23, the 14th year of Tianxuan, it was sunny, cloudless and windless on the Twin Islands. Qu Mao and Kong Ming, accompanied by the director of the Firearms Research Institute and seven senior researchers from the Firearms Research Institute, arrived at

The test firing site of the Firearms Research Institute.

Since the upgrade of Emperor Yi's territory and the upgrade of the lord's cabin also increased the area of ​​the twin islands in the middle, the test firing site of the Firearms Research Institute has also been expanded to a larger area.

When Qu Mao arrived at the test firing site, he quickly saw a machine gun about 1.5 meters long with an extended and widened ammunition belt at the rear end. However, the barrel of this machine gun was directly mounted on the sandbag bag, without any design or

Produced barrel supports for machine guns.

Following the order from the director of the Firearms Research Institute, three Firearms Army soldiers walked up to the machine gun. One Firearms Army soldier lay on the ground, put the handle of the machine gun on his shoulder, held the butt of the gun with one hand, and pressed it with the other.

on the trigger.

The other two Firearms Army soldiers squatted half-crouched on either side of the Firearms Army soldier responsible for shooting, and stretched out their hands to hold up the bullet chain to keep it horizontal.

"Shoot!" the director of the Firearms Research Institute shouted calmly.

"Da da da!", "ta da da!", "ta da da!" crisp machine gun sounds sounded, but Qu Mao's brows furrowed. This was too different from Qu Mao's impression of the existence of machine guns in another world.

The big differences are, firstly, the firing rate is too slow, secondly, the shooting posture is too awkward, and also, it can only shoot three consecutive rounds, and there must be a pause of one or two seconds after three consecutive rounds.

The director of the Firearms Research Institute sensitively noticed the change in Qu Mao's expression and said quickly: "Sir, this machine gun can indeed fire bullets continuously, but the accuracy of bullet shooting has changed significantly. The accuracy is not as high as before.

, especially the subsequent bursts of bullets.

Moreover, the recoil force is large, and the continuous recoil force requires higher physical fitness of the soldiers; and more soldiers are required to operate at the same time. If there are no soldiers on both sides to straighten the bullet chain, it is easy for the bullet to jam or mechanical failure."

Qu Mao thought for a while and said: "In another world, machine guns are not used for precise shooting, but to provide fire suppression.

When suppressing fire, few soldiers use machine guns to fire flatly. They usually tilt upwards at a certain angle, and then use the high speed of fire to quickly lay out a bullet coverage area within a certain range, and use the free fall of bullets to block the battlefield within a certain area.

As a result, the enemy does not dare to charge easily from that area.

Our Firearms Research Institute has produced such a machine gun so quickly, which is already a very good achievement. Of course, this machine gun still has a lot of room for optimization.

The rate of fire of the three-shot combo is difficult to achieve the kind of fire suppression effect I described. Of course, a barrel bracket can be designed in front of the barrel to enhance the stability of shooting..."

While commenting, Qu Mao took out a paper and pen and stood at the test firing site. While introducing, he drew a schematic diagram of the machine gun barrel bracket for the director of the Firearms Research Institute.

Kong Ming shook his goose feather fan, folded the schematic diagram drawn by Qu Mao, handed it to the director of the Firearms Research Institute, and said: "Director, please take your design drawing and go back to organize relevant researchers to study it carefully." Then Kong Ming turned to the director.

Qu Mao said, "Sir, our time is limited, why don't we look at other weapons?"

Qu Mao nodded and motioned to the director of the Firearms Research Institute to demonstrate other weapons.

At the instruction of the Firearms Research Institute, a Firearms Army soldier came out carrying a firearm similar to a breech-loading flintlock gun. Compared with the breech-loading flintlock gun, the trigger position of the firearm held by this soldier was wider.

In front of Qu Mao and Kong Ming, the firearms army soldier stuck a metal magazine containing 20 bullets in front of the trigger of the firearm, then pulled the bolt and put the firearm on his shoulder with one hand.

Holding the barrel of the gun, the other hand held the trigger, closed one eye and began to aim.

"Shoot!" the director of the Firearms Research Institute saw that the firearms army soldiers were ready and immediately ordered.

"Click!", "Click!", "Click!"... crisp gunshots rang out, basically two consecutive shots, and then the firearms army soldiers would wait for the barrel of the gun, which had been raised due to the recoil, to fall back down.

Only when you aim at the position will you continue to shoot.

When Qu Mao heard this voice, he nodded with satisfaction. Except that the burst speed of this submachine gun was not fast enough, there was not much difference between this submachine gun and the submachine guns in another world.

When the bullets in the magazine were finished, the firearms soldier pulled the bolt again, removed the empty magazine, and stuffed it into the front of his tactical vest.

Qu Mao nodded and said: "Well, the performance of the submachine gun is already very good. We can train the production personnel of the logistics department as soon as possible and enter the mass production stage.

Of course, at one end of the submachine gun in another world, pulling the trigger can instantly pour out all 20 rounds of bullets, and there are also single and continuous shooting modes to choose from."

The director of the Firearms Research Institute said: "Sir, I will organize researchers to further optimize and improve this submachine gun. Please rest assured, I will also inform the Logistics Department Xuande to send technical workers to the Firearms Research Institute to learn the production process.

.

Sir, please move over, let's go over here and take a look at the new weapon... Sir, you call it a mortar."

Under the leadership of the director of the Firearms Research Institute, Qu Mao and Kong Ming came to another open space at the test firing site of the Firearms Research Institute. In this open space, a few simple sandbags were piled together, leaning against these sandbags.

There was a bare metal barrel."

Qu Mao asked in astonishment: "That's it? Is this the mortar you made?"

The director of the Firearms Research Institute nodded and waved, and two Firearms Army soldiers came over holding an olive-shaped shell about 20 centimeters in length.

A Firearms Army soldier pressed his foot against the bottom of the barrel and tilted the barrel slightly. Another Firearms Army soldier gently pointed the tail of the cannonball at the barrel. Then he let go and the cannonball fell first.

Then there was a "bang" sound, and the shell popped out of the barrel again.

At a distance of less than 100 meters, the shell hit the ground and exploded with huge sparks.

Qu Mao's eyes lit up and he said: "It doesn't look good on the outside, but the effect is pretty good!"

Kong Ming also said: "Well, this artillery is more convenient to carry. It uses explosive bullets and its lethality is not small."

The director of the Firearms Research Institute said: "My lords, mortars do have many benefits, but it is a bit laborious to attack buildings, and unless you are a very experienced fighter, it is difficult to hit accurately."

Qu Mao thought for a while, then took out paper and pen again and drew a schematic diagram while explaining the principles of the mortar's bracket, aiming system, etc.

The director of the Firearms Research Institute immediately took out a pen and paper to record, and a test-firing experiment of a new weapon instantly turned into an academic seminar.
