Finding a cartridge in the chamber after firing, cleaning or checking the mechanisms requires immediate action - ignoring the rules of unloading can lead to spontaneous firing, damage to the bolt or injury. Reasons for cartridge delay range from incomplete retraction of the bolt carrier to defects in the magazine or extractor, and in models such as AK, AR-15 or SVD, the extraction algorithm is different. In this material - step-by-step instructions for safe discharge taking into account the design of a particular machine gun, as well as an analysis of common mistakes (for example, keeping your finger on the trigger or neglecting to check the barrel) and their consequences.
It is important to understand that the discharge procedure depends on the type of machine (for example, AK-74, AK-12, AR-15), its modifications and even the state of the mechanisms. Some models have safety levers, others are automatic shutter stops. We will look at universal principles that are suitable for most automatic and self-loading rifles, and also point out the nuances characteristic of specific systems.
If you have never unloaded a weapon before or doubt your actions, it is better to contact an instructor or an experienced gunsmith. This article is for informational purposes only and is not a substitute for hands-on training.
Why does the cartridge remain in the chamber: the main reasons
Before you begin discharging, it is important to understand why the cartridge was not removed normally. This will help avoid a repeat of the situation in the future. Here are the most common reasons:
- 🔹 Incomplete recharge: the bolt did not reach the rearmost position due to contamination, spring wear or weak impulse from the shooter.
- 🔹 Misfire: The cartridge primer did not fire, but the cartridge case remained in the chamber. Often occurs when using low-quality ammunition.
- 🔹 Firing delay: for example,
the shutter did not closedue to misalignment of the cartridge or dirt getting into the mechanism. - 🔹 Manual refueling: a cartridge was manually chambered (for example, when checking a weapon), but then not removed.
- 🔹 Design features: some models (eg AEK-971) have accelerated automation, which can lead to an incomplete recharge cycle.
The situation is especially dangerous when the cartridge remains in the chamber after last shot. Many machines (for example, AK-12) have a bolt stop that locks the bolt in the rear position after the magazine has been used up. However, if the cartridge was not automatically chambered (for example, due to a malfunction of the feeder), it may go unnoticed.
⚠️ Attention: Never rely solely on visual inspection of the chamber. Even if you think there is no cartridge, always follow the complete unloading procedure. Statistics show that up to 30% of accidents when handling guns occur due to an “empty” (as it seemed) chamber.
Preparing for discharge: safety precautions
Before you begin handling the weapon, make sure you are in safe zone. Ideal conditions:
- 📍 Indoor shooting range or a specially equipped place for disassembling weapons.
- 👥 Lack of strangers (especially children) within a radius of 10 meters.
- 🎯 Barrel direction in a safe direction (for example, into a bullet trap or earthwork).
- 🔦 Good lightingto clearly see the mechanisms.
Also prepare the necessary tools (if disassembly is required):
| Tool/device | Purpose | When you might need it |
|---|---|---|
| Cleaning rod or cleaning rod | To check the chamber for the presence of a cartridge | If the cartridge is stuck or is not visible visually |
| Screwdriver (phillips/flat head) | To disassemble the bolt carrier (during deep cleaning) | If the cartridge is not removed in the standard way |
| Safety glasses | Eye protection from possible fragments or powder gases | Mandatory when working with a jammed chuck |
| Gloves (optional) | Protect your hands from oil and sharp edges | During prolonged disassembly or cleaning |
Critically important: even if you are sure that the cartridge is not operational (for example, after a misfire), treat it as if it were a live cartridge. Powder in a cartridge case may ignite due to mechanical stress or heat.
Step-by-step instructions: how to unload a machine gun with a cartridge in the chamber
Below is a universal sequence of actions. For specific models (eg AK-103 or M4 Carbine) minor adjustments may be required.
-
1. Make sure the weapon is pointed in a safe place.
The barrel should be pointed into a bullet trap, an earthen bank, or upward (if you are in an open area). Never point a gun at people, animals, or flammable objects.
-
2. Put the weapon on safety (if any).
On most machines the fuse is located on the right side of the box (for example, AK - this is the lever above the pistol grip). Move it to position
"P"(or"S"for Western models). -
3. Remove the magazine.
Press the magazine release (usually located in front of the trigger) and remove it. Place the magazine aside, making sure that there are no cartridges in it (visually or by shaking).
-
4. Pull the bolt carrier back and lock it.
To do this:
- 👉 Grab the bolt frame (not the barrel!) and pull it sharply back.
- 👉 Secure it in the rear position using the slide stop (usually located on the left side of the box).
If the bolt does not lock, hold it with your hand.
5. Visually and tactilely check the chamber.
Look into the chamber from the side of the cartridge ejection window. If the cartridge is visible, carefully remove it. If not, use a cleaning rod (not a metal rod!) to check.
6. Remove the cartridge.
If a cartridge is stuck, do not try to force it out. Use extractor (if included) or contact a gunsmith. Using excessive force may damage the chamber.
7. Check the weapon for other ammunition.
Sometimes there may be extra rounds left in the barrel or feed mechanism (especially in open-bolt assault rifles). Conduct a complete audit.
8. Remove the safety catch and pull the trigger.
This is necessary to reset the firing mechanism. Do it only after full confidencethat the chamber is empty.
Make sure the barrel is pointed in a safe place|
Put the weapon on safety |
Remove magazine and check it|
Retract the bolt frame and secure it|
Check the chamber visually and tactilely|
Remove the cartridge without excessive force|
Check that there are no other cartridges in the mechanism -->
If at any stage you feel resistance or misunderstanding, stop manipulation and contact a specialist. For example, if the bolt does not retract, this may indicate chuck jamming or a broken return spring.
What to do if a cartridge is jammed in the chamber
A jammed cartridge is one of the most dangerous situations. Attempts to remove it by force can lead to a discharge or damage to the barrel. Here's what you can do:
- 🛑 Immediately stop attempting to remove the cartridge. Any excessive force may cause the sleeve to rupture.
- 🔧 Use a wooden or plastic rod. A metal cleaning rod can pierce the primer.
- 💧 Apply a few drops of oil onto the base of the sleeve and wait 5–10 minutes. This may help relieve the tightness.
- 🔨 Contact a gunsmith. Workshops have special pullers for jammed cartridges.
Never try:
- ❌ Knock out the cartridge by hitting the bolt frame.
- ❌ Heat the barrel or chamber.
- ❌ Use wire cutters or pliers to grab the sleeve.
⚠️ Attention: If the cartridge jams after misfiring, the risk of an accidental shot during removal increases significantly. In this case, the only safe option is to hand over the weapon to a specialist with an empty magazine and a locked bolt.
What happens when a cartridge case ruptures in the chamber?
When a cartridge case ruptures, metal fragments and powder gases under high pressure (up to 3000 atmospheres) can damage the bolt group, barrel and even the machine box. In the worst case, this results in injury to the shooter. It is especially dangerous if the rupture occurs when trying to remove the cartridge by force - in this case, the energy is directed towards the shooter.
Difference in discharge for different models of machines
Although the general principle of discharge is similar, some models have features. Let's look at the most common ones:
| Machine model | Features of discharge | Typical problems |
|---|---|---|
| AK-74/AKM | The shutter stop is on the right. Safety over the pistol grip. | The bolt may not lock in the rear position if the spring is weak. |
| AK-12/AK-15 | Extended bolt stop. Possibility of visual inspection of the chamber without retracting the bolt. | Sensitive to the quality of ammunition - frequent misfires when using cheap cartridges. |
| AR-15/M4 | Shutter stop lever on the left. Can be disassembled without tools. | The bolt group may jam if it is heavily contaminated. |
| Saiga/Vepr | Semiautomatics based on the AK, but with a modified bolt group. | .308 Win rounds can jam due to misalignment between the chamber and magazine. |
For example, in AR-15 To fix the shutter in the rear position, you must press bolt catch (shutter stop lever) after retracting the bolt. B AK-12 this operation is performed automatically when the delay button is pressed after the last shot.
For owners AK: If the shutter does not lock in the rear position, check the condition bolt springs. It often breaks or loses elasticity after 10–15 thousand shots.
If you experience frequent shooting delays, keep a “gun log” of cleaning dates, the type of ammo used, and the nature of the delays. This will help identify system problems (such as worn extractor or weak return spring).
Common mistakes when discharging and how to avoid them
Even experienced shooters sometimes make mistakes that can lead to injury or damage to the weapon. Here are the most common:
- 🔫 Pointing the barrel at yourself or others. Even if you are "sure" that the chamber is empty, the barrel should always be pointed in a safe place.
- 👈 Checking the chamber with your finger. This may result in accidental trigger pull or cutting from the sharp edges of the chamber.
- 🔄 Incomplete retraction of the shutter. If the bolt is not pushed all the way through, the cartridge may go undetected.
- 🛠️ Using inappropriate tools. For example, a screwdriver instead of an extractor to remove the cartridge case.
- 🚫 Ignoring misfires. After a misfire, a cartridge may ignite during the next reload cycle.
To minimize risks:
- ✅ Always follow the rule "four directions of security" (barrel, finger on the trigger, target, background behind the target).
- ✅ Use mirror or flashlight for inspecting the chamber in poorly lit places.
- ✅ Practice unloading your weapon with training cartridges (for example, SIRT or Dummy Rounds).
⚠️ Attention: One of the most dangerous habits is “dry training” (pulling the trigger without ammo) with military weapons. Even if you are sure that the chamber is empty, always first unload the machine according to the full procedure. Statistics show that up to 40% of dry training accidents are caused by a forgotten cartridge.
When professional help is needed
Some situations cannot be resolved on your own without risking life or damaging the weapon. Contact a gunsmith if:
- 💥 The cartridge is jammed so badly that the bolt does not move even after lubrication.
- 🔥 After a misfire, traces of soot or melting remained in the chamber (this may indicate case breakdown).
- 🔧 The bolt carrier or gas tube is deformed.
- 🎯 The machine gun fires in bursts when switched to single fire (problem with
gearboxor trigger mechanism). - 🔍 You are not sure of your actions or cannot visually confirm the absence of a cartridge.
Workshops use special equipment, for example:
- 🛠️ Extractors for jammed cartridges (for example, Otis Ripcord).
- 🔧 Torque wrenches for careful removal of the cartridge case.
- 🔬 Endoscopes to inspect the barrel and chamber.
Service cost for removing a jammed cartridge in gunsmith shops usually ranges from 1,000 to 3,000 rubles, depending on the complexity. This is cheaper than repairing the chamber after attempting to remove it yourself.
If, after removing the cartridge, you notice scratches or burrs in the chamber, be sure to show the weapon to a specialist. A damaged chamber can cause the cartridge case to rupture on the next shot.
FAQ: Frequently asked questions about discharging a machine gun
Is it possible to discharge a machine gun without retracting the bolt completely?
No. Incomplete retraction of the bolt does not allow the cartridge to be reliably removed from the chamber. In addition, in the half-open position, the bolt may block your view and you will not notice the remaining cartridge. Always retract the bolt all the way and lock it.
What to do if the cartridge cannot be removed after a misfire?
Wait at least 30 seconds (in case of delayed combustion), then carefully pull the bolt back. If the cartridge does not eject, do not use force - contact a gunsmith. Remember that the primer may not fire due to a defect, but the powder in the case remains dangerous.
How often should the chamber be checked after firing?
Checking the chamber should become a habit after everyone removing the magazine or finishing firing. Even if you fired practice cartridges, carbon deposits or shell fragments could remain in the chamber. In combat conditions, a check is carried out before each movement or change of position.
Can WD-40 be used to lubricate the chamber when it is jammed?
WD-40 is not recommended for permanent gun lubrication, but in an emergency it can be used to loosen a jammed cartridge. However, after using WD-40, it is necessary to thoroughly clean the chamber and apply a specialized gun lubricant (for example, Ballistol or CLP).
What is the difference between discharging a machine gun and discharging a self-loading rifle?
The main difference is the presence fire translator in vending machines. Before discharging, it must be moved to the position "single fire" or "fuse". In self-loading rifles (for example, SKS) this element does not exist. Also, in automatic rifles there are often shutter delays, which must be taken into account when fixing the shutter.
