Frequently Asked Questions
Shop Supporting BushingsWhat is the difference between 13:1 and 18:1 airsoft gears?
13:1 is commonly selected for faster cycling, while 18:1 is a conventional ratio often used in general-purpose builds. The final result still depends on the motor, spring, battery, gearbox condition, and installation.
Will every Gear Set fit both V2 and V3 gearboxes?
No assumption should be made from the category alone. Confirm the compatibility statement, selected variant, sector-gear configuration, and complete product specification before ordering.
