Modernized Kalashnikov assault rifle, known throughout the world as AKM, became a symbol of Soviet and Russian military power, going through dozens of local conflicts and remaining the main small arms in many armies around the world. Despite the external similarity with its predecessor, the AK-47, this type of weapon has undergone significant design changes aimed at reducing weight, improving firing accuracy and manufacturability. Understanding the operating principles of this machine gun is necessary not only for military personnel, but also for anyone interested in the history of small arms.
The introduction of this machine gun into the troops made it possible to significantly increase the mobility of infantry units without loss of firepower. Mikhail Kalashnikov and his team of engineers have managed to create the perfect balance between reliability, ease of maintenance and combat effectiveness. It was these qualities that made AKM the most popular machine gun in history, which is still in service with dozens of countries and continues to be produced under licenses.
In this article we will examine in detail the technical features, history of creation and tactics of using this legendary weapon. You will learn exactly how the upgraded version differs from the basic one, how to properly operate the machine gun in the field, and what myths surround its use in a real combat situation. A deep understanding of the material part is the key to the successful completion of combat missions.
History of creation and modernization of the AK-47
Development AKM began shortly after the adoption of the first model of the Kalashnikov assault rifle in 1949. The army needed lighter and more technologically advanced weapons that could be produced on a huge scale with less metal and time. By the mid-1950s, the design bureau under the leadership M.T. Kalashnikov introduced a number of improvements that formed the basis of the new model.
The key change was the transition from a milled receiver to a stamped one from sheet steel. This decision made it possible to reduce the weight of the machine gun by almost a kilogram, which was of enormous importance for an infantryman carrying a full load of ammunition. In addition, stamping reduced the cost of production and speeded up assembly, which was critically important during the Cold War and the need to equip a multimillion-dollar army.
Why was a milled receiver considered better?
Many people mistakenly believe that a milled AK-47 frame is stronger. In fact, it is heavier and more difficult to manufacture, and under extreme loads it can burst. The AKM stamped box is more elastic and better withstands dynamic loads when firing, while remaining lighter.
It is important to note that the modernization affected not only the receiver. Was implemented trigger retarder, which improved the accuracy of burst fire, especially for less experienced shooters. Changes also affected the sighting devices and the muzzle compensator, which together increased the effectiveness of fire at medium distances.
- 🔫 Transition to a stamped receiver made of 1 mm thick sheet steel.
- ⚖️ Reducing the weight of the machine gun without cartridges to 3.1 kg.
- 🎯 Introduction of a compensator to reduce vertical bullet deflection.
- 🔧 Simplification of disassembly and maintenance of mechanisms in the field.
Technical characteristics and device
Construction AKM is based on a proven gas engine and butterfly valve design. The automation works by removing powder gases through a side hole in the barrel wall. This system is highly reliable even when heavily soiled or using low-quality cartridges, making the weapon ideal for difficult climatic conditions.
The barrel of the machine gun is chrome-plated inside, which protects it from corrosion and facilitates cleaning after shooting. The bore has four right-hand rifling. To compensate for barrel toss when firing in bursts, a compensator is screwed onto the muzzle, which directs the powder gases upward. This allows the shooter to better keep the weapon on the line of sight.
When cleaning the AKM barrel, always use a cleaning rod on the chamber side to avoid damaging the muzzle and compensator, which can negatively affect the accuracy of the fire.
The trigger mechanism allows for single and automatic fire. The fire selector is located on the right side of the receiver and at the same time serves as a fuse, locking the bolt frame in the extreme forward and rear positions. This design solution eliminates an accidental shot when the machine gun falls or receives a strong blow.
Below is a table of the main tactical and technical characteristics AKMthat every soldier should know:
| Parameter | Meaning | Note |
|---|---|---|
| Caliber | 7.62 mm | Cartridge 7.62×39 mm |
| Machine length | 870 mm | Without bayonet |
| Weight without cartridges | 3.1 kg | Stamped box |
| Rate of fire | 600 rounds/min | Theoretical |
| Sighting range | 1000 m | Effective up to 400 m |
Key differences between AKM and AK-47
Visually distinguish AKM from his predecessor AK-47 (especially a 1949 model with a milled box) can be difficult for an untrained person, but a number of signs are striking to an experienced specialist. First of all, attention is drawn to the shape of the receiver: the AKM has characteristic stampings and thinner walls, while the sides of the early AK-47 were smooth and massive.
The second important difference is the presence of a muzzle compensator. On AKM it has a complex shape with two holes at the top, whereas on the AK-47 the muzzle was often smooth or simply threaded without a compensator. Also on the AKM sight rail you can see the letter “A”, indicating an upgraded version, although this feature is not present on all copies.
The trigger retarder is another hidden but important difference. It is located inside the mechanism and is not visible from the outside, but its presence determines the nature of burst fire. U AKM the queue is more even, the “piece” of the queue scatters bullets less than the old model. This engineering achievement increased the likelihood of hitting group targets.
- 🔍 The presence of the letter “A” on the aiming bar (not always).
- 📉 No milled grooves to reduce weight on the sides of the receiver.
- 🛡️ Different butt angle and pistol grip shape (on later versions).
- 🔩 Magazine fastening: AKM magazine hooks have notches for better retention.
Combat use and tactics of use
In real combat conditions AKM has established itself as a universal weapon of close and medium combat. The tactics of its use are based on firing short bursts (2-5 shots) at a distance of up to 300-400 meters. It is not recommended to shoot in long bursts due to the rapid consumption of ammunition and significant spread of bullets, despite the operation of the compensator.
When firing from a kneeling or prone position, the shooter should press the buttstock tightly to the shoulder, using a belt for better fixation. AKM has noticeable recoil, and the correct stop allows you to quickly return the front sight to the aiming line after a shot. Single fire is used to hit single targets at distances over 400 meters, where accuracy is important.
⚠️ Attention: During prolonged continuous shooting, the barrel of the machine gun becomes very hot. Do not touch the barrel or gas chamber with unprotected hands to avoid burns. Allow the weapon to cool down or change the barrel if the design allows (in a standard AKM - only change the machine gun).
At night or in conditions of limited visibility, the use of tracer cartridges to adjust fire is effective, although this may unmask the shooter. The bayonet-knife, which is a standard accessory, can be used not only for hand-to-hand combat, but also as a tool for overcoming obstacles or cutting through barbed wire.
The main principle of tactics with AKM is maneuver with fire and short bursts. Do not try to suppress the enemy with long bursts, it is better to change your position more often and use cover.
Maintenance and care of the machine
Reliability AKM directly depends on regular and proper care. The basic rule is: weapons must always be clean, lubricated and ready for battle. After each firing, the barrel bore, gas chamber and moving parts must be cleaned of powder deposits and copper using a cleaning solution and rags.
The lubricant is applied in a thin layer to the rubbing surfaces: bolt frame, bolt, rods. Excessive lubricant in winter can lead to hardening and failure of mechanisms, so in cold weather special winter oil is used or it is applied minimally. In sandy areas, the amount of lubricant is also reduced so that sand does not stick to the mechanisms.
Procedure for partial disassembly of AKM:1. Separate the store.
2. Check to see if there is a cartridge in the chamber.
3. Take out the pencil case with accessories.
4. Separate the cleaning rod.
5. Separate the receiver cover.
6. Separate the return mechanism.
7. Separate the bolt frame from the bolt.
8. Separate the bolt from the bolt frame.
9. Separate the gas tube from the barrel lining.
Regularly checking the attachment of the stock, handle and front sight will help you avoid trouble at a critical moment. Any gaps must be eliminated. Particular attention should be paid to the condition of the striker: it must move freely in the bolt channel and protrude above the bolt cup by at least 1.5 mm.
- 🧼 Wipe the barrel bore dry after cleaning with solvent.
- 💧 Lubricate metal surfaces with a thin layer of gun lubricant.
- 🌡️ In winter, use winter grease or kerosene to clean off old grease.
- 👁️ Conduct a daily inspection of weapons before going on a mission.
Common myths about AKM
Around AKM There are many legends that often have nothing to do with reality. One of the most popular myths is that the machine gun “doesn’t jam even in the mud.” Although the reliability of the Kalashnikov assault rifle is truly phenomenal, the entry of large abrasive particles (sand, clay) into the mechanism can still cause a delay in firing. Weapons require maintenance, even if they are considered “indestructible”.
Another myth concerns the accuracy of the battle. Many people believe that AKM it shoots “like a god,” but in reality, without proper training of the shooter and proper preparation, the accuracy leaves much to be desired, especially in bursts. High efficiency is achieved only with skillful handling and understanding of bullet ballistics.
Is it true that AKM penetrates body armor?
The standard 7.62×39 mm cartridge (LPS) confidently penetrates body armor of the 2nd protection class (GOST R 50963-96) at distances of up to 300 meters. Modern body armor of class 3 and higher (with ceramic or steel plates) can withstand a hit, but the impact energy will still be high.
There is also an opinion that Soviet soldiers never cleaned their machine guns, and they still worked. This is a dangerous misconception. The army had strict cleaning regulations, and weapons were maintained in exemplary order. The survivability of mechanisms in the mud is a safety margin for an emergency, and not a guide to neglecting maintenance.
⚠️ Attention: Never use gasoline or aggressive solvents to clean the wooden parts of the stock and forend, as this can destroy the varnish coating and the structure of the wood, making the weapon unusable.
Frequently asked questions (FAQ)
What is the main difference between AK and AKM?
The main difference lies in the production technology of the receiver (milled for AK and stamped for AKM) and the presence of a muzzle compensator on the AKM. The AKM is also lighter and has a trigger retarder for better accuracy.
Is it possible to fire blank cartridges from an AKM?
Yes, you can, but for automatic shooting you must use a special blank chamber (CH), which is placed on the muzzle. Without HP, the automation will not work due to lack of gas pressure.
What is the actual effective firing range?
Although the target range is 1000 meters, effective shooting at a human figure is carried out up to 400-500 meters. Further, the bullet loses energy and accuracy, becoming less effective.
Why was the AKM stock often made of plywood?
The use of multi-layer birch plywood made it possible to save scarce hardwood, reduce weight and prevent deformation of the stock from moisture and temperature changes.
