Direct removal of the bolt frame requires first disconnecting the magazine and checking that there is no cartridge in the chamber, which is a mandatory safety condition before starting any manipulations with the weapon. Incomplete disassembly Kalashnikov assault rifle, a video of which is often searched for to visualize the process, begins precisely from this stage, allowing you to quickly clean the mechanism of contaminants and lubricate the main components. Mistakes at this stage, such as attempting to remove the receiver cover without pulling the charging handle back, can result in the mechanism jamming or damage to the recoil spring.
Carrying out maintenance operations correctly AK-74 or AKM guarantees the durability of the weapon and the absence of delays when shooting in the field. In this guide, we will go through the sequence of actions in detail, based on technical documentation standards, so that you can safely carry out the procedure at home or at the shooting range. It is important to understand that even with video materials, theoretical training and knowledge of the mechanisms play a decisive role.
As you work, you will need a flat surface, rags, gun lubricant, and possibly a cleaning rod to clean the bore. Strictly prohibited carry out complete disassembly unless absolutely necessary, as this disrupts the alignment and increases wear on the seating areas of the parts. Below is a detailed algorithm of actions that will help you avoid common mistakes made by beginners.
Preparation for disassembly and safety precautions
Before starting any work on a firearm, you must ensure that it is unloaded. Visual and tactile inspection of the chamber is the first action the owner must perform Kalashnikov assault rifle. Even if you are sure that the magazine is empty, mechanically removing the bolt will make sure that there is no cartridge. Ignoring this rule is a gross violation of safety regulations.
The workplace should be well lit and free from foreign objects. For partial disassembly AK-74M or its modifications, a table covered with a clean cloth is enough to prevent small parts such as pins or springs from getting lost or dirty. It is recommended to use a special case included in the spare parts kit to store the removed pins and knockouts.
⚠️ Warning: Never begin disassembly while the weapon is live or cocked. Before starting work, be sure to release the trigger, keeping the barrel pointed in a safe direction (towards the bullet catcher or the ground).
Particular attention should be paid to the condition of hands and tools. Oily or slippery fingers can cause the screwdriver or cleaning rod to slip, resulting in injury or damage to the blued finish. If you use a video for training, pause it before each action to fully understand the mechanics of the process, and not just copy the movements.
Sequence of incomplete disassembly of the machine
The partial disassembly process is standardized and includes several sequential operations that must be performed strictly in a certain order. The first step is always to branch off the store. To do this, grab the neck of the magazine with your left hand, and slightly turn it forward with your right to disengage it from the latch. After this, the magazine is freely removed downwards.
The next step is to check for the presence of a cartridge in the chamber. Pull the charging handle (bolt frame) all the way back, inspect the chamber and release the handle. Then you need to unscrew the pencil case with accessories, which is found in many modifications, such as AK-74, located in the butt or on the receiver cover (depending on the model). To do this, remove the cleaning rod from under the barrel and use it to unscrew the plug of the pencil case.
The receiver cover is separated after retracting the reloading handle all the way back. With your right hand, press the cross pin (button) at the rear of the receiver and lift the cover up. This opens access to the return mechanism and bolt group. Next comes the removal of the return mechanism: moving the handle back a little, remove the heel of the return spring from the groove of the bolt frame and move the mechanism forward.
☑️ Pre-cleaning checklist
To remove the bolt frame with the bolt, pull the handle all the way back and, lifting it up, remove the frame from the receiver guides. After this, the bolt can be separated from the frame. To do this, take the frame in your left hand, and with your right hand, pull the bolt back all the way, turn it so that the combat cylinder disengages, and move it forward. The separation of the gas tube from the barrel lining is performed by turning the gas tube lock to a vertical position.
Complete disassembly: when and how to do it
Complete disassembly Kalashnikov assault rifle It is carried out only in case of deep contamination, repair or replacement of faulty parts. Unlike incomplete, it requires special tools and deeper knowledge of the mechanism. Frequent complete disassembly unnecessarily leads to accelerated wear of the mating surfaces and disruption of the accuracy of the combat.
The process includes disassembling the bolt, trigger mechanism, trigger mechanism (trigger mechanism) and fire selector. To knock out the axles and pins, use a drift from the spare parts kit or a copper punch to avoid damaging the metal. For example, to remove the trigger, it is necessary to knock out the trigger axis, after which it is easily removed from the trigger body.
Disassembling the bolt requires care, since the firing pin and mainspring are located inside. The hammer pin is knocked out with light blows, after which the parts are removed. Assembly is carried out in the reverse order, however, when installing the firing pin, you must ensure that the firing pin is positioned correctly.
⚠️ Attention: Independent complete disassembly of the trigger mechanism without proper qualifications can lead to incorrect assembly, which will make the weapon dangerous for the owner and others (for example, a spontaneous shot is possible).
USM details
The trigger mechanism consists of a trigger, a trigger, a self-timer, a connecting bar and corresponding springs. All these elements require regular lubrication and checking for cracks or chips, especially in the area of combat platoons.
Cleaning and lubrication of main components
After disassembly, all metal surfaces must be thoroughly cleaned of carbon deposits, powder deposits and old grease. To clean the bore and patina, use a brush wound on a cleaning rod soaked in solvent. Rubbing is carried out until there are no more traces of soot on the wipe. Particular attention is paid to the gas piston, which is often coked by the combustion products of gunpowder.
Lubrication is carried out with special weapon oil (RZh, RP or analogues). Lubricate It is necessary to apply a thin layer to all rubbing surfaces: bolt frame, combat cylinders, receiver guides. Excess oil in winter can lead to freezing of the mechanism, so in cold weather winter lubricant is used or a minimal amount is applied.
Wooden parts (fore-end, butt, lining) are wiped with a dry cloth. If the wood is very dirty, you can use a slightly damp cloth, but immediately wipe it dry. After cleaning and lubrication, the metal parts are assembled, and a control check of the operation of the automation is carried out (without a chuck).
| Machine node | Type of pollution | Cleaning Tool | Service frequency |
| :--- | :--- | :--- | :--- |
| Bore | Soot, lead coating | Brush, rags, solvent | After each shooting |
| Gas chamber | Coking with powder gases | Scraper, brush, salt | After 200-300 shots |
| Bolt carrier | Old grease, dust | Rags, solvent | After each cleaning |
| USM | Dust, thickened grease | Brush, rag | When completely disassembled |
Tip: To clean hard-to-reach places, such as the inside of the gas tube, use cotton swabs soaked in solvent or special small-diameter brushes. This will help avoid the accumulation of carbon deposits, which can interfere with the removal of gases.
Typical mistakes when servicing AK
One of the most common mistakes is using the wrong lubricants. The use of motor oils, grease or vegetable fats is unacceptable, as they change their properties with temperature changes, thicken in the cold or dry out, forming an abrasive slurry. This leads to delays in firing and accelerated wear of parts.
Another mistake is being overzealous in knocking out the pins during complete disassembly. Strong impacts can deform the holes in the receiver or break the pin itself, which will require a complex repair from a gunsmith. All knockout operations must be carried out with light, precise blows.
Some owners forget to check the condition of the return spring. Over time, the metal may “get tired” and the spring will lose its elastic properties, which will lead to a lack of movement of the moving parts forward and delays in shooting. If the spring has visible defects or deformation of the coils, it must be replaced.
⚠️ Attention: Never use gasoline, kerosene or aggressive acids to clean the chrome bore. This can damage the chrome coating, after which the barrel will quickly begin to corrode and lose accuracy.
Main conclusion: Regular and correct partial disassembly with cleaning and lubrication prolongs the life of a Kalashnikov assault rifle more effectively than rare complete disassemblies using aggressive chemicals.
Assembling the machine after servicing
Assembly AK-74 or AKM done in the reverse order of disassembly. First, a gas tube with a barrel lining is installed and secured with a lock. Then the bolt carrier with the bolt is inserted (the bolt must be in the extreme forward position). The frame is inserted into the grooves of the receiver and brought forward all the way.
After this, the return mechanism is inserted, and the heel of the spring must fit into the corresponding groove of the bolt frame. The receiver cover is put on and secured with a cross pin. Finally, a store is added. Be sure to perform a test rotation of the mechanism, moving the reloading handle several times to ensure smooth operation.
The final step is to check the descent. When the machine gun is assembled (without a magazine or cartridges), the trigger should be cocked, and when the trigger is pressed, it should be released. The fire switch must clearly switch between the “OD” (single) and “AB” (automatic) modes, blocking the release in the “P” (safety) position.
Checking the self-cocking function
When setting the "AB" mode and smoothly moving the bolt frame forward, the trigger should automatically be cocked. If this does not happen, check the condition of the self-timer and its spring.
Questions and answers (FAQ)
How often do you need to completely disassemble a Kalashnikov assault rifle?
Complete disassembly should only be performed when repairs, deep contamination or replacement of parts is necessary. For regular maintenance, partial disassembly is sufficient. Frequent complete disassembly unnecessarily harms the life of the weapon.
Can WD-40 be used to clean an AK?
WD-40 is great for removing old grease and moisture, but it is not a lubricant. After cleaning with this product, it is necessary to apply specialized gun oil, since WD-40 evaporates quickly and does not protect against friction.
What should I do if the shutter does not go all the way during assembly?
Check the correct installation of the return mechanism and the position of the bolt frame. Often the problem is that the heel of the spring is not in the groove of the frame or the frame is warped. Do not use force, it is better to disassemble the knot and try again.
Do I need to lubricate the bore after cleaning?
Yes, the bore must be coated with a thin layer of lubricant to protect against corrosion, especially if the weapon is stored for a long time. Before shooting, it is better to remove excess lubricant with a dry rag to avoid excessive deposits.
How does disassembling an AK-74 differ from an AKM?
The disassembly principle is identical. The main differences relate to the design of the muzzle brake-compensator (on the AK-74 it is removable) and the material of some parts (plastic/aluminum on the AK-74M versus wood/steel on the AKM), but the algorithm for incomplete disassembly is the same for the entire family.
