Queensland Police: STOP and Think

Before purchasing, carrying or using a gel blaster, make sure you understand your responsibilities under Queensland law.

• You must be at least 18 years old to purchase a gel blaster in Queensland. If this is your first gel blaster order with us, you will be required to provide valid photo identification for age verification.
• Store your gel blaster in a locked container when it is not being used.
• When transporting or carrying a gel blaster in public, keep it completely covered and out of public view.
• Never display a gel blaster in public or use it in a way that may cause fear or alarm.
• Never point or fire a gel blaster at another person without their permission.
• Never shoot animals or enter private property without permission.
• Do not modify a gel blaster to fire ammunition or operate outside its intended specifications.
• Always use appropriate eye protection and handle your gel blaster responsibly.

Misuse of a gel blaster may result in serious criminal penalties. Your choices have consequences—STOP and think before you act.

For current information, visit the Queensland Police Service Gel Blasters page.

Shoot Responsibly

• Eye and face protection designed for gel blaster use must be worn by the user and any person within range.
• Always treat your gel blaster as loaded, even after the magazine has been removed.
• Never look directly into the barrel, even if the gel blaster appears to be unloaded. If a blockage occurs, remove the magazine, engage the safety, and make sure the product is fully unloaded before inspecting or cleaning it.

Use Batteries Safely

• Unplug the battery when the blaster is not in use.
• Only use a battery with the correct voltage, connector and specifications for your gel blaster.
• Stop using the battery immediately if it becomes swollen, damaged, unusually hot, leaks or produces an unusual smell.

Charge Batteries Safely

• Only use a compatible charger.
• Charge batteries on a stable, non-flammable surface in a cool, dry and ventilated area.
• Never leave a charging battery unattended, and unplug the battery once fully charged.
• Allow the battery to cool down before charging it.

Gel Ball Safety

• Gel balls are not edible. Keep them away from young children and pets.
• Drain excess water from your gel balls before loading them into the magazine. Do not use gel balls that are too wet.

Before inspecting or repairing your gel blaster, remove the magazine, set the fire selector to safety mode, and wear eye protection.

No Response / Dead Trigger

• Check whether the battery is charged and working properly.
• If your gel blaster has a MOSFET, set the selector to Safe then switch it back to Semi or Full-Auto.

MOSFET Clicks, but Gel Blaster Won’t Fire

• Hold the trigger for 8 seconds to reset the MOSFET, then disconnect and reconnect the battery. Set the selector to Safe, then switch it back to Semi or Full-Auto.

Gel Blaster Fires, But Gel balls Don't Drop Out

• Test a different magazine, as a faulty magazine may not feed properly.
• Add more gel balls to the magazine.
• Use gel balls of the correct size and hardness. Gel balls that are too large or too soft may break inside the barrel.

Gear Grinding Noise

• Stop firing immediately, disconnect the battery and arrange an inspection.

Semi-Auto Stops Working

• Switch to Full-Auto, fire one short burst, then return to Semi-Auto.

Battery or Wiring Becomes Hot

• Stop using the blaster and disconnect the battery. Do not reuse a swollen, damaged or unusually hot battery.

Pistol Grip Becomes Hot

• This is normal because the motor is located inside the pistol grip and generates heat during firing.

Low FPS or Short Distance

• The blaster may require servicing or spring replacement. Contact CyberTrigger for inspection.

Poor Accuracy

• Use hard, correctly sized and fully hydrated gel balls.
• Clean the barrel and adjust the hop-up gradually.
