Partial disassembly of the Kalashnikov assault rifle is performed for cleaning, lubrication and inspection of components when contamination interferes with the normal operation of the mechanism or the moving parts are jammed. This process requires strict adherence to the sequence of actions, since violation of the order of removing the pin of the receiver lining can lead to damage to the forend or loss of small parts in the field.
Video instructions often show an accelerated pace, but when servicing the weapon yourself, you need to focus on recording each click and position of the levers. Errors during assembly, especially when installing the bolt carrier and rotating bolt, can cause failure to fire or, more dangerously, ballooning of the cartridge case when fired.
⚠️ Attention: Before starting any manipulations, make sure that the weapon is unloaded, the chamber is free, and the magazine is disconnected. It is strictly forbidden to disassemble a loaded machine.
Preparing for service and checking safety
The first step in any maintenance is to visually inspect and check that there is no cartridge in the chamber. Bolt carrier must be pulled back all the way to ensure that the barrel bore moves freely. If you are preparing to clean after shooting, allow the barrel to cool, as handling hot metal can cause burns and improper distribution of lubricant.
For work, you will need a flat, clean surface, preferably covered with soft material, to avoid damage to wooden or polymer parts if parts accidentally fall. AK-74M and its variants have a plastic stock and forend, which are more impact resistant than wood, but still require careful handling.
⚠️ Warning: Never start disassembling with your finger on the trigger. The index finger must be kept outside the trigger guard until the mechanism is checked for operation after assembly.
There are two types of disassembly: incomplete and complete. An incomplete one is made to care for the weapon in everyday use, while a full one is required only for deep repairs or severe contamination after being in water or dirt. Complete disassembly without the need and special skills is prohibited to avoid violating factory settings.
Release the magazine and check the chamber
The process begins with detaching the magazine, which is a basic action for any shooter. With your left hand, grasp the neck of the magazine, and with your right, slightly push it forward, overcoming the force of the latch. The movement should be confident, but not sharp, so as not to damage the magazine lock on the machine body.
When removing a magazine in cold or muddy conditions, lightly tap the bottom of the magazine with the palm of your hand to dislodge any accumulated snow or dirt before reinstalling.
After removing the magazine, you must visually and tactilely check the chamber. To do this, pull the charging handle back all the way and look through the ejector window. Make sure there is no cartridge, casing, or foreign object in the chamber. Close the ejector window with the lid, releasing the handle, and perform a control release, pointing the weapon in a safe direction.
Bayonet and pencil case compartment with accessories
If installed on the machine bayonet, it must be removed before further disassembly. Press the bayonet lock button located on the cross with the thumb of your right hand, and at the same time turn the bayonet down with your left hand, and then remove it from the muzzle. This action frees up access to the front sight and muzzle for subsequent cleaning of the bore.
The pencil case with accessories is usually located in the butt socket for classic models or in the butt channel for modern modifications. To remove, press the socket cover with your finger and the pencil case will come out under the action of a spring. Inside are rubbing, brush, drift and oiler necessary for maintenance.
- 🔪 The bayonet is removed only after the magazine is disconnected for safety.
- 🧰 The pencil case with accessories must be removed before separating the receiver cover.
- 🧹 Rubbing is used to clean the bore of gunpowder soot and copper.
Separating the receiver cover and the return mechanism
To access the internal mechanisms, you must remove the receiver cover. With your right thumb, press the rear lip of the cap down and forward to remove it from the transverse groove of the receiver. Then lift the back of the cover and remove it. The action requires some effort, especially on new types of weapons.
Then move the charging handle forward as far as it will go and remove the recoil mechanism. It consists of a return spring, a guide rod and a buffer washer. Remove the mechanism smoothly, controlling the force of the spring so that it does not jump out suddenly. Inspect the spring for broken coils or corrosion.
Separating the bolt carrier with bolt and gas tube
The next step is to remove the bolt carrier. Pull the charging handle all the way back, lift its rear part and smoothly remove the bolt carrier and bolt from the receiver. Don't try too hard; if the frame does not move, check whether the handle is retracted all the way.
To separate the gas tube from the receiver, turn the gas tube lock up to a vertical position. After this, remove the gas tube moving forward and upward. Gas chamber remains on the barrel, and the tube with the lining is separated entirely. This allows access to the bolt carrier piston for cleaning.
Features of the gas tube
A lot of carbon deposits accumulate inside the gas tube, which, when heated, can cause self-ignition of the lubricant or cartridges. Clean the internal cavity with a brush regularly.
Disassembling the bolt carrier and bolt
Disassembly of the shutter itself is carried out only in case of severe contamination or malfunction. Take the bolt frame in your left hand, and with your right hand, pull the bolt back, turning it so that its lug comes out from under the figured cutout of the bolt frame. After this, pull the bolt forward.
When assembling, it is necessary to align the protrusions of the shutter with the grooves of the frame. Battle ledges must fit into their guides correctly, otherwise the shutter will not fit into place. Lubricate rubbing surfaces with a thin layer of gun oil, avoiding excess oil, which attracts dust.
| Machine node | Cleaning frequency | Lubricant type | Tool |
|---|---|---|---|
| Bore | After every shooting | Gun lubricant | Ruff, rubbing |
| Bolt carrier | Weekly | Thin layer of oil | Rags, brush |
| Gas tube | Once a month | Do not lubricate inside | Ruff, cleaning rod |
| Return spring | Once every six months | Grease | Rags |
☑️ Checklist before assembly
Assembling the machine after cleaning
Assembly is carried out in the reverse order of disassembly. Start by attaching the bolt to the bolt carrier. Align the longitudinal groove of the bolt with the protrusion of the bolt frame and insert the bolt until it stops. Make sure it moves freely inside the frame.
Then insert the bolt carrier and bolt into the receiver. The handle should point to the right. Bring the frame to its most forward position. After this, attach the receiver cover by inserting its front end into the transverse groove and pressing the rear tab until it clicks.
The main sign of correct assembly is a characteristic metal click when closing the receiver cover and free movement of the bolt frame.
Install the gas tube with the barrel strap, inserting its rear end into the groove of the sight block, and lower the front end onto the gas chamber. Lock the tube by turning the locking device downwards. Make sure the tube fits snugly and does not wobble.
Inspection and check of mechanism operation
After complete assembly, it is necessary to check the operation of the automation. Vigorously jerk the bolt frame several times, making sure that it moves smoothly, without jamming or squeaking. Trigger should work accurately: release occurs only when the shutter is completely closed.
Check that the barrel bore is locked securely. When cocking the hammer and pressing the trigger (in compliance with safety measures), a blank shot should occur. If the machine is equipped with a flag fire switch, check its operation in the “Single” and “Automatic” positions.
⚠️ Attention: If during assembly you feel strong resistance or parts do not fall into place, do not use force. Reassemble the assembly and check that the parts are correctly oriented.
Storage
After cleaning and assembly, store the machine in a dry place. If the weapon is stored for a long time, the lubricant layer should be thicker to prevent corrosion.
How often do you need to completely disassemble a Kalashnikov assault rifle?
Complete disassembly should only be done if absolutely necessary, for example, after the weapon gets into water, sand, or if there is severe contamination that interferes with the operation of the mechanisms. For regular cleaning, partial disassembly is sufficient.
How to lubricate a Kalashnikov assault rifle in winter?
In winter, at subzero temperatures, it is necessary to use special frost-resistant lubricants that do not thicken in the cold. Regular gun oil can harden and cause automatic failure.
What to do if the bolt carrier does not reach the stop?
It is necessary to check the cleanliness of the chamber and bore, the absence of foreign bodies in the receiver, as well as the correct assembly of the return mechanism and gas tube.
Is it possible to clean the machine without video instructions?
Yes, if you have studied the material part of the weapon and have experience. However, for beginners, video instructions and diagrams are a must to prevent mistakes during the first disassembly.
