Frequently asked questions

What exactly does a gearbox assembly do?
A gearbox assembly forms the complete drive core that regulates energy transfer, ensuring your shots are delivered consistently and powerfully.

Are all gearbox assemblies compatible with every configuration?
No, choose the right assembly for the right gearbox version. A V2 gearbox will only fit in a replica built on a V2 gearbox.

When should I choose a complete gearbox instead of separate parts?
A complete gearbox is ideal if you want a stable base without extensive adjustments; it offers convenience and technical certainty.

Does the choice of material for the gearbox shell have a significant impact?
Yes, sturdier materials ensure less flex and a longer service life, which is especially important in powerful configurations.

Can I further upgrade a gearbox assembly?
Yes, this category offers sufficient scope to optimise parts such as gears, pistons and motors later on for specific playing styles.

In addition to your gearbox assembly, choose additional categories such as hop up units, buckings, motors, batteries and technical maintenance products. These combinations enhance performance and ensure a reliable and efficient set-up.
