ак-47 is the автоматкалашников of Russia. From 1950 to 1980, it was the standard equipment of the former Soviet army and Warsaw Pact countries. 1After the small-caliber ак-74 was equipped with the former Soviet army in the 1980s, the ак-47 series withdrew from Soviet equipment.

There are two models of AK47: folding stock and fixed stock. It can fire 7.62mm M43 medium-sized bullets from the former Soviet Union, with single shot and multiple shots. The gun has the advantages of simple structure, fierce firepower, good service, few faults and durability, which is very suitable for soldiers to fight by car. It can still shoot normally in harsh environments such as sandstorm and muddy water. It is the most famous and widespread weapon in the world and one of the six famous guns in the world. The former Soviet Union once equipped troops for use, and it was also widely used by former Warsaw countries and third world countries, and was also provided to Palestinian guerrillas for use. During the Vietnam War, the former Soviet Union provided AK47 to the South Vietnamese National Liberation Front in large quantities. On the battlefield, the gun has fully demonstrated its good combat performance and is very popular with soldiers. Even American soldiers have taken great interest in this kind of gun. Their slogan is: throw away M 16 and pick up AK47.

The barrel of the gun is connected with the shell by thread, the rifling part is 369mm long, and the barrel is chrome plated. The shooting performance is very good at both high and low temperatures. The shell is machined from forgings. The magazine is made of steel or light metal and can be interchanged in all weather conditions.

The firing mechanism is hammer rotary, and the firing mechanism directly controls the hammer to realize single shot and continuous shot. The launching mechanism is mainly composed of a frame, a fail-safe device, a stopper, a trigger, a reducer, a single-shot rod, a hammer, a fail-safe stopper and the like.

The speed machine is located on the right side of the gun. When the reducer is set in the automatic position, the rear protrusion of the iron block is pressed by the lower protrusion of the reducer and cannot rotate, so the hammer cannot be buckled. At this point, the firing resistance iron buckles the hammer and becomes a fired state. After the trigger is pressed, the iron block releases the hammer, and the hammer rotates and fires. After that, as long as the trigger is pulled, the firing resistance and the single-shot resistance can't hold the hammer, and only the bamboo shoots that are not in place can resist the hammer groove. When the frame returns to its original position and presses down the transmission rod of the misplaced safety iron block, the stuck bamboo shoots are separated from the hammer clamping groove, and the hammer rotates to fire. Repeat the above actions in the future to realize continuous shooting.

When the reducer is set in the semi-automatic position, before the first bullet is fired, the iron block buckles the hammer and becomes a state to be struck. After the trigger is pressed, the hammer is released and the single-shot iron rotates forward together. If you hold the trigger, the hammer will be overwhelmed by the gun rack and held by the single iron after firing. At this time, because the frame has not been put back in its original position, the transmission rod of the safety block is raised, and there is a gap between the bamboo shoots and the hammer groove. When the frame is put back in its original position, the hammer will be buckled by the single-shot iron. If it is fired again, the trigger must be released first to release the single-shot iron from the hammer, and then the hammer will be buckled by the firing iron and ready to fire again.

If the frame does not re-enter the position, the bolt locking is uncertain. At this time, it is not safe to release the bamboo shoots extending from the frame, so the bamboo shoot retaining iron cannot be separated from the hammer groove. Therefore, even if the trigger is pressed, the hammer cannot rotate forward, thus forming a misplaced safety.

When the handle of the reducer is in the highest position, its lower protrusion abuts against the rear protrusion of the single-shot stopper and the right side of the rear protrusion of the trigger, so the trigger cannot be pulled, and safety is realized. If the hammer is in the position to be struck at this time, and there are bullets in the chamber, the hammer cannot be released because the trigger cannot be pulled, thus forming a rear safety. If the hammer is in the firing position at this time, because the trigger can't be pulled, the stopper can't rotate forward, and the hammer is blocked by the stopper when it falls backward, so the frame can only sit backward for a short distance, and the bullets in the magazine can't be pushed into the chamber, thus forming forward safety.

The gun adopts mechanical sight and is equipped with night vision sight. Both the cylindrical sight and the U-notch photo door of the scale have reversible accessories, which contain the fluorescent substance radium 22 1. The scale is divided into 100 ~ 800 m, one is divided into 100~800m, and the combat scale is set to 300 m. However, when aiming with the sight, the height can only be corrected by twisting the sight up and down, but the wind direction deviation cannot be corrected. Moreover, when shooting at night, the sight wing is often mistaken for the sight.
