Before You Play

  • Soak gel balls for 3–4 hours.
  • Fully charge the battery before use.
  • Carefully load the magazine (don’t overfill).
  • Test fire in a safe area to get comfortable.

Once you’ve completed these steps, you’ll be ready for your first game.

Blaster Safety & Maintenance

Proper care depends on your blaster type. Below, find safety and maintenance tips for electric, gas, and manual gel blasters.

  • Electric Blasters:

    - Use only compatible batteries and chargers.
    - Never overcharge; disconnect after charging.
    - Clean the barrel after each use.
    - Store in a cool, dry place, removing the battery when not in use.
  • Gas Blasters:

    - Use only recommended gas canisters for your model.
    - Check seals and valves regularly for leaks.
    - Keep the gas reservoir clean and dry.
    - Store in a cool environment; avoid extreme temperatures.
  • Manual Blasters:

    - Ensure all moving parts are lubricated as needed.
    - Avoid over-compressing springs; load gently.
    - Store in a stable position to avoid mechanical stress.

Tailor your care steps to your blaster type, ensuring safety and longevity.

Troubleshooting & Common Mistakes

Even seasoned players run into issues. These quick tips can get you back in the game fast.

  • Blaster not firing? Check if the battery (electric) is charged or the gas reservoir is full.
  • Gel balls breaking? Ensure they are fully soaked and use appropriate quality.
  • Magazine not feeding? Remove, reload carefully, and ensure a proper fit.
  • Common mistake: Dry firingβ€”always have gel balls loaded before firing.

If issues persist, contact support or revisit your setup steps.

Soaking & Storage of Gels

When soaking the gels, they need to be soaked fully submerged in warm water from the tap for a minimum of 4-6 hours.

Once they have fully grown you can leave them in the water and keep them in or out of the refrigerator.

When you are ready to use them just drain off any excess water with a strainer before you feed them into the mag but do not dry them as they need to be lubricated to work properly.
