Legendary Kalashnikov It is not just a weapon, but a cultural phenomenon that is recognized in all corners of the globe. Its history goes back more than seven decades, during which the structure underwent many changes and upgrades. From the first prototypes created in post-war Izhevsk to modern high-tech complexes designed for special forces.
Many people still confuse AK-47 Later modifications, considering that it is the same product. In fact, the evolution of small arms in the Soviet Union and Russia has been a leap, giving rise to dozens of options. Mikhail Kalashnikov And his students were constantly improving the nodes, improving ergonomics and adapting the machine to new cartridges.
In this article we will discuss in detail major modificationswhich were produced serially and were in service. You will learn how the wooden butt differs from the plastic one, why you need a swivel cutoff and why modern versions have received Picatinny bars.
The Origin of Legend: AK-47 and its predecessors
The story begins in the late 1940s, when Soviet designers were faced with the task of creating a reliable automatic weapon for an intermediate cartridge. The first mass model became AK-47It was put into service in 1949. It was a revolutionary design for its time, combining ease of service with high combat efficiency.
The first versions of the machine had stamped-boxThis allowed to reduce the cost of production, but affected the product resource. Later, in 1951, it was decided to switch to a milled box, which significantly increased the weight, but increased the reliability and accuracy of the battle. It is the milled versions that are valued most highly by collectors today.
⚠️ Attention: Early AK-47 models did not have a compensator on the muzzle of the barrel, which made shooting bursts less heated compared to subsequent modifications.
The design of the shutter group and the gas piston with a long stroke became uniqueThis allows the automation to work even in the most extreme pollution conditions. The mechanism was so perfect that the basic principles of its work are preserved in modern weapons.
Why index 47?
The 47 in the name does not mean the year of the prototype, but the year of completion of the main tests and preparation for mass production, although the machine was adopted in 1949.
Modernization of 1959: the emergence of AKM
The real breakthrough was the modernization of 1959, which gave rise to the AKM (The Kalashnikov machine is modernized). The main change was the return to the technology of stamping the receiver, but at a higher technological level. This allowed the weight of the machine to be reduced by almost a kilogram, which was critical for infantry.
The design came up descenterwhich provided a smoother trigger force and increased accuracy of shooting. Also, the machine received a new muzzle compensator, which reduced the tossing of the barrel when firing bursts. These changes made the weapon more convenient to handle for a soldier of any size.
- 🔫 Reduced weight of weapons due to stamped box.
- 🎯 Improved accuracy of combat thanks to the compensator and moderator.
- 📉 Reducing the cost of production on a massive scale.
Outwardly. AKM It is easy to distinguish by the oblique cut of the muzzle compensator and the characteristic stiffness ribs on the store. This model became the most mass-produced machine in the world and was produced under license in many countries of the socialist camp.
When inspecting the machine, pay attention to the sighting bar: the AKM it is graded up to 1000 meters, while the early AK-47 - only up to 800 meters.
Transition to small caliber: family AK-74
In the 1970s, the global trend in the arms industry shifted towards a decrease in caliber. The Soviet Union was no exception, creating a 5.45 mm cartridge and a new machine gun under its designation. AK-74. This change dramatically affected the ballistics and striking ability of the bullet at distances up to 500 meters.
New muzzle-compensator It had no longer a slanting, but a two-chamber design with side holes, which significantly reduced the recoil and removal of the barrel to the side. The machine received plastic parts (butt, forearm, pistol handle), which were lighter and more durable than wood in conditions of high humidity.
| Characteristics | ACM (7.62 mm) | AK-74 (5.45 mm) |
|---|---|---|
| Mass without bullets | 3.1 kg | 3.3 kg |
| The length of the barrel | 415 mm | 415 mm |
| Initial bullet speed | 715 m/s | 900 m/s |
| Targeting range | 1,000 m m m m m m | 1,000 m m m m m m |
It is important to note that the switch to a small caliber allowed the soldier to carry more ammunition at the same weight. Trajectory decorum The new bullet greatly simplified the aiming at medium distances, which was confirmed by combat use in local conflicts.
The AK-74 was the first mass-propelled assault rifle in the world to be upgraded to a caliber less than 6mm, setting the trend for NATO and other armies.
Shortened and special modifications
For the needs of airborne troops, armored personnel and special forces personnel, more compact weapons were needed. The answer of the engineers was the creation of AKS-74U (The Kalashnikov machine is shortened.) This weapon is often mistakenly called a submachine gun, although by the principle of operation it is a full-fledged machine gun.
Shortening the barrel to 206.5 mm required a change in the design of the gas chamber and muzzle device. Nana AKS-74U installed original compensator, resembling the shape of a "cone", which performs the function of a flame arrester and reduces the sound of the shot. The folding stock allows you to conveniently transport weapons in a bag or under clothing.
Other specialized versions were also developed. For example, AK-105 It became a modern replacement for shortened models, having a more ergonomic plastic butt and the ability to fasten additional accessories. Sniper support for infantry was established RPK-74 (Kalashnikov Hand Machine Gun) with a heavy barrel and bipods.
- 🎒 Perfect compactness for concealed wearing and working in transport.
- 🔥 High rate of fire, compensating for a short sighting line.
- 🛠 Possibility of installing silencers and collimator sights.
⚠️ Attention: Shooting from shortened automatic rifles requires special care due to the increased muzzle wave and the possibility of injury by fragments of ricocheting bullets when firing in confined spaces.
The hundredth series and export potential
In the 1990s, when the Iron Curtain collapsed, the Izhevsk Machine-Building Plant began active work on export versions of the machine. And so the "hundredth series" was born.AK-101, AK-103, AK-104 and others. These models have retained the reliability of their predecessors, but received a modern appearance and unification in many nodes.
The main visual difference was black. plasticIt replaced the brown stock and the folding stock, which could be adjusted in length. AK-103 It combines modern ergonomics and a good old 7.62mm cartridge, making it popular in countries where the ammunition is in the billions of units.
Semi-automatic versions have been developed for the civilian market in the United States and other countries, such as: Saiga and AK-100 series civilian. They often have a store capacity limiter and design changes needed to comply with local law, but the internal "stuffing" remains army-based.
☑️ Signs of a genuine AK
Newest Time: AK-12 and Digitalization
The modern stage of development is marked by the appearance of the automaton AK-12adopted by the Russian army in 2018. This is not just a cosmetic upgrade, but a deep reworking of the design, taking into account the experience of recent decades and the requirements of modern war.
The machine got it. telecast with adjustable back of the neck, which allows you to fit the weapon under any arrow and type of equipment (including body armor). The shape of the forearm has changed, Picatinny straps have appeared for installing any modern sights, flashlights and laser target designators without the need to drill weapons.
Internal changes affected the mechanism of fire transfer: it became possible to fire in short fixed bursts (cut off by 2 shots). Improved accuracy of combat and ergonomics of controls, which have become more convenient for use in gloves.
The myth of double-barrel
There were rumors online that the AK-12 had two guns. This is not true: the design remained classic, the changes affected only the interface and internal mechanisms.
Frequently Asked Questions (FAQ)
What is the difference between the AK-47 and the AKM?
The main difference lies in the technology of manufacturing the receiver (molded from the AK-47 against the stamped from the AKM) and the presence of a muzzle compensator in the modernized version. AKM is also lighter by about 1 kg.
Why does the AK-74 have such a strange muzzle compensator?
The two-chamber structure with side holes serves to remove powder gases to the sides, which compensates for the tossing of the barrel up and the withdrawal to the right, characteristic of automatic shooting.
Can I install optics on older AK models?
On the classic versions (AKM, AK-74), only the side bracket for night sights was normally attached. Installation of modern optics required replacement of the receiver lid or the use of special adapters for the whole.
Is the AK-12 a completely new weapon?
No, it's a deep upgrade to a proven platform. Automation remained gas with a long stroke of the piston, but significantly improved ergonomics, accuracy and the ability to attach equipment.
