A jammed AEG is one of the most common issues players experience. Fortunately, most jams are simple to fix and don’t require a full strip-down.
Before taking anything apart, follow this guide carefully.
⚠ First – Make It Safe
Before attempting any fix:
- Remove the magazine
- Disconnect the battery
- Switch the gun to safe
- Keep the gun pointed in a safe direction
Never work on an AEG while it is still powered.
Common Causes of AEG Jams
- Low-quality or damaged BBs
- Dirty inner barrel
- Hop-up blockage
- Weak battery
- Gearbox lock-up
- Double feeding
Identifying the cause helps prevent it happening again.
Step 1: Check for a Simple BB Jam
Most jams happen in the hop-up or barrel.
How to Clear It:
- Remove the magazine.
- Set hop-up to zero (fully off).
- Insert a clean unjamming rod into the barrel from the muzzle end.
- Gently push the stuck BB back toward the hop-up chamber.
- Shake out any loose BBs.
⚠ Never force the rod aggressively — you can damage the hop rubber.
Step 2: Try Firing on Semi-Auto
If the gun won’t fire on full auto:
- Switch to semi-auto
- Reconnect the battery
- Fire a single shot
Sometimes the gearbox has stopped mid-cycle, and a semi shot will reset it.
If it fires, disconnect battery again and test normally.
Step 3: Check Your Battery
A weak battery can cause:
- Slow trigger response
- Clicking noise but no firing
- Gearbox locking up
Try a fully charged battery before assuming a mechanical fault.
Step 4: Listen for Clicking
If you hear a single click when pulling the trigger:
- The motor may be trying to turn
- The gearbox could be locked
Try switching to semi and firing once.
If it still doesn’t cycle, you may need a technician to safely release the anti-reversal latch.
Step 5: Clean Your Barrel
A dirty barrel can cause feeding problems.
Use:
- Cleaning rod
- Lint-free cloth
- Silicone oil (very small amount)
Clean from the chamber end where possible.
What NOT to Do
❌ Do not keep pulling the trigger repeatedly
❌ Do not force the motor height screw
❌ Do not strip the gearbox unless experienced
❌ Do not use low-quality BBs
Repeated trigger pulling can cause serious gearbox damage.
When to Seek Professional Repair
You may need servicing if:
- Grinding noises occur
- Motor gets hot
- Gun won’t fire at all
- BBs shatter inside
- Fuse repeatedly blows
Internal gearbox repairs require proper tools and experience.
Preventing Future Jams
✔ Use high-quality BBs
✔ Keep barrel clean
✔ Use correct battery voltage
✔ Don’t overspin on full auto constantly
✔ Maintain your hop-up
Regular maintenance prevents most AEG issues.
