Airsoft Gun Repair: The Ultimate Checklist for UK Players

Essential Maintenance Tools

• Precision screwdriver set
• Needle-nose pliers
• Silicone oil
• Silicone grease
• LT2 grease
• Rubbing alcohol
• Cleaning rod and patches
• Cable ties (various sizes)
• Basic hex key set

1. Common Faults and Quick Fixes

• Feeding Issues
  • Check magazine spring tension
  • Clean feed tube and hop-up chamber
  • Inspect BB quality and size consistency
  • Check recoil and nozzle spring percentages (for GBB)
  • Clean and reapply silicone lubrication (for GBB – should be done after all game days)
    
• Power Loss
  • Test battery charge (for AEGs)
  • Check air seal components
  • Inspect main spring condition
  • Verify cylinder compression
  • Make sure you’re using the correct PSI gas for different weather, the colder the temperature the higher PSI gas may be required (green/red/black)
    
• Accuracy Problems
  • Clean inner barrel
  • Adjust hop-up settings
  • Check barrel alignment
  • Replace worn hop-up rubber
  • Check nozzle alignment

2. Preventative Maintenance Schedule

After Each Game Day

• Clean barrel with isopropyl alcohol
• Wipe down external surfaces
• Check for loose screws
• Inspect magazine condition

Quarterly Maintenance
