The question is how many types of Kalashnikov assault rifle are there? exists in the world, does not have a simple and unambiguous answer, since we are talking about a whole family of small arms, numbering dozens of modifications. If we take into account only the Soviet and Russian official models that were in service, their number is in the dozens, but if we add here licensed versions produced in other countries and countless homemade copies, the number will go into the hundreds. The basis for all these variations was the design, ingenious in its simplicity, developed by Mikhail Timofeevich Kalashnikov in the late 1940s.
The evolution of the legendary weapon occurred in stages, responding to the challenges of the time and the military’s requirements for reliability, combat accuracy and ergonomics. AK-47 became the ancestor, followed by modernized versions, versions with a folding stock, shortened versions and specialized modifications for special forces. Understanding the differences between these models is important not only for historians or collectors, but also for those interested in modern military equipment and the history of weapons making.
In this article we will analyze in detail the main stages of development of the machine gun, highlight the key technical features of different generations and try to systematize a huge amount of information about the different versions of this weapon. You will find out what is different AKM from its predecessor, why it appeared AK-74 and what is unique about the latest developments of the Kalashnikov concern. This is a journey through decades of engineering, where every detail matters.
First generation: the birth of a legend and AK-47
The story begins with the adoption of the 1947 model Kalashnikov assault rifle into service by the Soviet Army. This event occurred in 1949, although the development itself was completed two years earlier. AK-47 became the first model in which it was possible to combine high reliability of operation in extreme conditions with sufficient accuracy of fire for mass-produced weapons. The design was based on proven solutions, but had a unique survivability of the mechanism.
The first versions of the machine gun, known today as the "first type", had a receiver milled from a single piece of steel. This made the weapon heavy and labor-intensive to manufacture, but incredibly durable. Later, in 1951, it was replaced by a modification with a milled box of lightweight construction, and then, in 1954, a version with a sighting bar without a crossbar appeared. All these changes were aimed at optimizing production without losing combat qualities.
⚠️ Attention: Do not confuse the original Soviet AK-47 with modern commercial replicas. The original assault rifles from the first years of production are of museum value and have specific features, such as the absence of a muzzle flash compensator on early models.
A feature of the first generation was the ability to install bayonet, which became an integral attribute of the image of the Soviet soldier. Although the machine was relatively easy to use, it required regular cleaning and lubrication to maintain the perfect balance of the mechanisms. It was during this period that the very recognizable silhouette that is known in all corners of the planet was formed.
AKM era: technological breakthrough and mass appeal
The mid-1950s were marked by the emergence AKM (Avtomat Kalashnikov Modernized), which is often mistakenly called simply AK-47. The main difference was the production technology of the receiver: instead of milling, it began to be manufactured by stamping from sheet steel. This revolutionary change made it possible to drastically reduce the weight of weapons, reduce the labor intensity of production and, as a result, increase production volumes.
In design AKM a muzzle compensator appeared, which reduced the toss of the barrel when firing in bursts, which had a positive effect on the accuracy of the battle. The machine also received a trigger mechanism with a retarder, which improved the stability of the machine. A version was created for airborne and special units AKMS, equipped with a folding metal butt, which fit under the receiver.
- 🔫 Weight: Reducing the weight of an unloaded machine gun to 3.1 kg (versus 4.3 kg for the early AK-47).
- 🎯 Accuracy: The introduction of a compensator improved the dispersion of bullets.
- 🏭 Production: Stamped technology made it possible to produce millions of weapons.
- 🪖 Modularity: The appearance of a version with a folding stock for airborne troops.
The AKM became the most popular assault rifle in history, its licensed versions were produced in China (Type 56), Poland, East Germany, Romania and many other countries. It is this model that most often appears in the chronicles of local conflicts in the second half of the 20th century. The reliability of the system was so high that it continued to work flawlessly even after falling into water, mud or sand, which became the standard for all small arms in the world.
Why is AKM lighter than AK-47?
The main reason for the weight reduction lies in the technology of manufacturing the receiver. Milling a single piece of metal required the removal of up to 50% of the material, while stamping from a 1 mm thick sheet made it possible to create a hollow structure of the desired shape immediately, while maintaining the necessary rigidity due to riveting and additional inserts.
Small caliber: transition to 5.45 mm and AK-74
In 1974, an assault rifle entered service with the Soviet Army. AK-74, marking the transition to the small-caliber 5.45x39 mm cartridge. This change was dictated by global trends (a similar transition in the United States to 5.56 mm) and the need to increase the direct shot range and the penetration ability of armor. Externally, the machine gun became recognizable thanks to a new muzzle attachment of a complex shape, which served as a compensator and flash suppressor.
Go to small caliber made it possible to reduce the weight of a soldier's wearable ammunition and reduce recoil when firing. The design of the machine gun has undergone changes: plastic fittings (stock, fore-end, magazine) were introduced, which replaced wood. Plastic was not only lighter, but also more resistant to moisture, although it was inferior to wood in strength under extreme mechanical loads.
There were many modifications from this period, including AKS-74 with a folding stock and AKS-74U (shortened), which became a symbol of public order and special forces. The shortened version had a barrel length of only 210 mm, which made the weapon compact, but significantly reduced the ballistic characteristics and increased the muzzle flash and the sound of the shot.
| Model | Caliber | Barrel length | Weight (without cartridges) | Year of adoption |
|---|---|---|---|---|
| AK-47 | 7.62×39 mm | 415 mm | 4.3 kg | 1949 |
| AKM | 7.62×39 mm | 415 mm | 3.1 kg | 1959 |
| AK-74 | 5.45×39 mm | 415 mm | 3.3 kg | 1974 |
| AKS-74U | 5.45×39 mm | 210 mm | 2.7 kg | 1979 |
| AK-74M | 5.45×39 mm | 415 mm | 3.4 kg | 1991 |
Implementation plastic stores became another characteristic feature of the era. They were lighter and cheaper to produce than metal magazines from AKM, and had a characteristic “ribbed” surface for better grip on the hand. However, early examples of plastic were brittle in the cold, which sometimes led to problems with feeding cartridges in extreme climate conditions.
Modern classics: 100 series and AK-74M
By the early 1990s, scattered modifications were replaced by a unified series known as the “hundredth”. The base model was AK-74M, which replaced the AK-74 and AKS-74. The main innovation was a universal side rail for mounting optical and night sights, which significantly expanded the tactical capabilities of a fighter in low light conditions.
All accessories of the machine gun, including the butt, fore-end and magazine, began to be made of impact-resistant black plastic. The butt, unlike previous folding models, could be folded on both sides, which increased the comfort of wearing weapons in body armor and when getting into vehicles. Inside, the machine also received improvements that increase barrel life and reliability in dirty conditions.
When inspecting 100 series machines, pay attention to the quality of the plastic. Original Soviet and early Russian plastic has a specific matte texture, while cheap fakes often have a glossy sheen and a characteristic chemical smell.
At the base AK-74M a whole family of weapons with calibers of 5.45 mm, 7.62 mm and even 9 mm was created. For example, AK-101 and AK-103 are intended for export and use NATO 5.56 mm and old Soviet 7.62 mm cartridges, respectively. AK-104 and AK-105 They are shortened carbines designed to replace the obsolete AKS-74U, having improved ergonomics and the ability to install additional equipment.
The 100 series became a bridge between the Soviet heritage and modern requirements for modularity. It was during this period that the active introduction of tactical accessories began, such as under-barrel grenade launchers, grips and laser designators. The machine gun has ceased to be just a means for shooting, turning into a platform for solving specific combat tasks.
The newest generation: “Two Hundreds” and “One Thousand Twelves”
In the 21st century, the family was replenished with models that absorbed all the experience of local conflicts. AK-200 and its development - AK-12 (for 5.45 mm) and AK-15 (for 7.62 mm) - represent a deep modernization of the classic scheme. The main difference was the ability to quickly change the barrel, which is critical for maintaining firepower in protracted battles, although this function is rarely used in mass use.
The designers paid special attention to ergonomics: a length-adjustable telescopic butt cheek appeared, which allows you to comfortably aim both in a bulletproof vest and in ordinary clothes. The mechanics of the machine gun were modified to reduce barrel toss and improve accuracy of fire, especially in automatic mode. The introduction of a two-way fire safety switch was one of the most noticeable external changes, making it easier to control the weapon with the left hand.
The AK-12 is equipped with an integrated Picatinny rail on the receiver cover, which firmly fixes optical sights without disrupting zeroing even after removing and installing the cover. This solution was not given to engineers for a long time, since the classic Kalashnikov design with the lid mounted on an axis did not provide the necessary stability. Now the machine gun can be equipped with collimator sights, thermal imagers and night sights of any standard.
- 🛠️ Modularity: Ability to install a wide range of tactical equipment.
- 📏 Ergonomics: Adjustable stock and improved handle shape.
- 🔥 Accuracy: Improved mechanics reduces bullet spread by 1.5-2 times.
- 👁️ Visibility: Optical rails allow you to conduct effective combat at any time of the day.
⚠️ Attention: The external similarity of the AK-12 and AK-15 does not mean complete identity. Differences in caliber (5.45 mm vs. 7.62 mm) require different bores and bolt groups. Using ammunition of the wrong caliber will result in fatal weapon failure and injury to the shooter.
☑️ Signs of modern modification
Specialized and experimental modifications
In addition to the main lines, there were many specialized versions created for specific tasks. For example, ACML and AKMLN were equipped with night sights, which made it possible to conduct effective fire in the dark. Created for accurate shooting at medium distances ACMN with an optical sight, although it was not a full-fledged sniper weapon due to the ballistics of the machine gun.
Stands apart AK-9 - a silent machine gun designed for special forces. It uses special heavy bullet cartridges and an integrated suppressor, making the shot virtually inaudible at a distance. This weapon is designed to covertly eliminate enemy personnel protected by body armor at distances of up to 200 meters.
Experimental samples such as AK-2000 (bullpup layout) or AKB-1 (with balancing automatic), demonstrate the search for ways to further improve characteristics. However, the classic scheme turned out to be so effective that radical changes to the layout most often did not find support from the military. However, work to increase barrel life and reduce weight is still ongoing.
Specialized modifications are created for specific tasks (night combat, silent shooting), but are based on the same proven automation as the basic models.
Global distribution and licensed copies
When answering the question of how many types of Kalashnikov assault rifle there are, one cannot ignore the geographical factor. More than 20 countries received production licenses, including China, Poland, East Germany, Czechoslovakia, Hungary, Romania, Bulgaria, Yugoslavia, Egypt, India and others. Each country made its own changes to the design, adapting it to its production capabilities and tactical requirements.
Chinese Type 56 was originally a complete copy of the AK-47, but later acquired a folding bayonet and a receiver cover with ventilation holes. German MPi-K and Polish Pkm had their own characteristics of finishing and markings. Israeli Galil, although considered a separate development, structurally goes back to the Kalashnikov assault rifle, being adapted for the 5.56 mm cartridge and Israeli operating conditions.
There are also so-called “custom” versions created by private companies or enthusiasts. They may differ in materials (titanium, carbon), coating and the presence of non-standard controls. However, functionally they remain the same Kalashnikov assault rifle, proving the genius of the original concept, which has remained relevant for more than 70 years.
Which Kalashnikov assault rifle is the most reliable?
The classic AK-47 of the first type with a milled receiver and a thick barrel is considered the most reliable. However, it is also the heaviest. Modern AK-12 and AK-15 combine the high reliability of their predecessors with improved ergonomics and accuracy, using modern materials and production technologies.
What is the difference between AK-47 and AKM?
The main difference is in the manufacturing technology of the receiver (milled for the AK-47 versus stamped for the AKM) and the presence of a muzzle compensator for the AKM. The AKM is also lighter and more technologically advanced to manufacture, making it the most widely used assault rifle in the world.
Why does the AK-74 have such a strange choke tube?
The double-chamber choke tube on the AK-74 serves to compensate for barrel flip and reduce muzzle flash when firing small-caliber 5.45 mm cartridges. Its shape is optimized for the ballistics of this particular cartridge.
Is the AK-47 still in production?
The original Soviet AK-47 has long been out of production. However, many countries continue to produce its licensed and unlicensed copies, which are often referred to as the “AK-47” in common parlance, although technically these may be versions of the AKM or their analogues.
