ALL GEL BLASTERS ARE PRETESTED TO BE 100% SO THEY PASS QC
Do not upgrade any part of your toy gel blaster as this will void the warranty. Upgrades refer to changing the battery voltage (7.4-11v), motor, springs, gears, piston to anything other than stock parts or same material types (nylon gears with nylon gears) not worried about the brand.
Warranty will not be void if you pull apart to service or repair your blaster as needed if needed (replace stock gears with same type, replace battery with same voltage, replace springs with same gauge type material and motor with same type torque / rpm).
Any questions about warranties or returns can be asked by email or you can check out our policies page.
Make sure you check your state laws before purchase!
In Queensland they are legal and South Australia you may need a permit.
