At Karl's request, Philip replaced a shooter and let Carl, the owner of the company, take the action himself.

The first is Philip's explanation of the structure and use of the new assault rifle. A new gun was divided by two in Philip's hands, and it disintegrated into a pile of parts as if by magic.

Under the astonished eyes of everyone, Philip said seriously: "Guys, this new rifle is called an assault rifle. As you have just seen, its structure is simple and compact, easy to disassemble and assemble, and this gun uses a large number of aluminum alloy parts and plastic parts. For example, its foldable butt is made of high-strength plastic, and the upper and lower receivers are stamped and formed by high-strength aluminum alloy, which has the advantage that the weight of the whole gun is greatly reduced, the weight of the whole gun does not exceed 3.8 kg, and the butt is folded up, which is very easy to carry. ”

Philip picked up the barrel: "Look at the barrel of this gun, it is processed by cold forging process, which improves the finish, dimensional accuracy, and surface strength of the barrel, prolongs the life of the barrel, and improves the shooting accuracy of the gun." The entire barrel length is 450 mm, firing 5.8 mm small-caliber rifle rounds, with an effective range of 400 meters and a maximum range of 600 meters. The muzzle velocity of the muzzle can reach 900 meters per second, which is much higher than the muzzle velocity of the current mainstream rifle, so the power of this small-caliber bullet is greater. ”

Philip picked up the upper and lower receivers of the aluminum alloy and said: "The gun body is composed of upper and lower receivers. The upper receiver is connected to the rear cover, barrel, etc. through the section sleeve, and the lower receiver is equipped with the main parts such as the launcher and the butt, and the receiver is connected by two receiver pins at the front and rear. This 5.8mm assault rifle uses an automatic method with a short stroke of the piston, and after the piston rod hits the automaton, the automaton is suspended on the automaton rail on the upper receiver to complete the mechanism action. The biggest advantage of this structure is that it maintains a high level of reliability even in windy and sandy conditions. Even if it falls into muddy water, although the gun body is covered in muddy water, the automaton and receiver guide are still clean after disassembly, and the movement of the bolt will not be affected in any way. ”

A pile of parts in Philip's hands, quickly turned into a beautiful assault rifle, everyone seemed to be enjoying an artistic performance, Philip's movements did not have a trace of hindrance and hesitation, it was completely as if it was effortless, in fact, what everyone didn't know was that Philip could assemble the gun in a very short time even if he blindfolded.

After assembling it, Philip picked up the new gun and continued: "The structure of the muzzle device plays an important role in the silence and flame suppression of automatic weapons, given that the length of the barrel and the type of projectile are determined. This kind of muzzle device with compact structure, good silencing and flame suppression effect is a cylindrical cavity inside, the opening is trumpet-shaped, and there are square holes on the side. The purpose is to increase the cross-sectional area of the airflow outlet, so that the airflow can expand more fully, reduce the airflow pressure and temperature, so as to achieve the purpose of flame suppression. When firing, the gunpowder gas ejected at high speed rushes out of the muzzle mouth, enters the internal cavity of the muzzle device, and further consumes energy through expansion, depressurization, friction, vortex and other effects. In addition, the reduction of gas pressure can also reduce the intensity of the shock wave and reduce the muzzle flame. ”

Carl and Lucas listened intently, still thinking about it. Anna didn't understand it at all, but she could see that Philip's performance was eye-catching, and the shooters and workers at the Bofors factory had envious expressions on their faces. Anna is even more convinced that she is not wrong, that Philip is really the prince charming of her life.

After introducing the muzzle device, Philip picked up a magazine of thirty rounds and inserted it into the bolt, only to hear a click, and the magazine was perfectly integrated with the barrel of the gun.

Philip continued: "The firing mechanism of the 5.8mm assault rifle is composed of a fast and slow machine, a single-shot iron arrester, an iron blocking body, an assembly sleeve, a hammer, a failure insurance, a transmitter card, a transmitter shaft and a spring, which has the advantages of simple structure and good reliability. There are 3 positions in the fast and slow machine, 0 is the insurance; 1 is a single shot; 2 is a burst shot. When the firearm is usually stored, when checking that there is no bullet in the chamber, pull the trigger to put the hammer in a state of release, and pull the fast and slow machine to the safety position. The mechanical sighting device adopts a combination mechanism of a hole-type illuminator and a columnar crosshair. The flip-type door is fixed on the door base, and there are three scales of 1, 2 and 4 on the ruler, which indicate the aiming position with a range of l00m, 200m and 400m respectively. There are two fluorescent dots on the front sight retainer for rough aiming during night battles. The aiming base of the new gun is 520mm long, the optical sight mount is arranged on the plane of the upper receiver cover in front of the illuminator, and the gantry structure is adopted, which allows the installation of white light sights and low-light sights. ”

Karl asked curiously: "Philip, our assault rifle is indeed good, shorter than ordinary rifles, but can it be loaded with bayonets?" If it is not possible to get on the bayonet, it will be a big flaw. ”

Philip nodded and said, "Mr. Karl is right! An assault rifle is no better than a submachine gun, it can also be loaded with a bayonet. When installing the bayonet, first put the bayonet ring into the muzzle device, so that the T-shaped groove on the handle is aligned with the T-shaped protrusion of the bayonet seat on the gun, and then pull it back into place, at this time, the T-shaped protrusion of the bayonet seat is stuck by the left and right clamps of the shank seat, and the bayonet ring is inserted into the gas expansion chamber of the muzzle device, and the bayonet is installed; When unloading the bayonet, hold down the left and right clips on the handle and draw the bayonet backwards from the muzzle direction. ”

Seeing Karl nodding with satisfaction, Philip picked up a huge circular drum and said with a smile: "Mr. Karl, this is a hundred-round drum, after being mounted on an assault rifle, it can form a rate of fire of more than seven hundred rounds per minute, and the firepower is powerful, comparable to a light machine gun." In addition, even with a 30-point magazine, if a skilled soldier can shoot from an empty compartment and form a continuous firepower, let me demonstrate it to you! ”

After speaking, regardless of everyone's surprised reaction, Philip picked up the new assault rifle in his hand, pulled the bolt, adjusted the fast and slow machine to the burst position, and then firmly pressed the butt against his right shoulder, held the large plastic grip in his right hand, hooked the trigger with his index finger, and gently held the lower cover with his left hand. Philip pointed the muzzle of his gun at a small dirt slope hundreds of meters away, and as the index finger of his right hand pulled the trigger, the muzzle of the new assault rifle sprayed a dense rain of bullets.

The gunshots rang out incessantly, and a dense stream of bullets shot on a small dirt slope hundreds of meters away, raising puffs of dust. I saw that when the first magazine was about to finish, Philip hooked the trigger with the index finger of his right hand and did not relax, and his left hand grabbed a magazine from the row of magazines in front of him, and used it to push down the magazine pick on the receiver, the empty magazine fell to the ground with a click, and the new magazine was replaced, and Philip held the grip firmly with one hand, and the muzzle of the new assault rifle hardly saw any beating, still spitting tongues of fire, and the bullets continued to shoot hundreds of meters away.

It took Philip less than two seconds to change the magazine with one hand, and everyone present was stunned...... Even Anna, a layman, saw that Philip's hand was extraordinary, and the look in his eyes towards Philip became even more complicated.
