What this part is

This is a single B-Grade AEG spur gear from our boneyard salvage stock. It is a low-cost option for tech-bench builds, spares boxes and gearbox repairs where a new-in-box gear set is not needed.

Condition and honesty

Being used or salvaged, the gear may show wear on the teeth or bushing surfaces. It is sold as spares or for repair with no warranty, so it suits experienced builders who can inspect and shim it properly.

Compatibility

AEG spur gears commonly fit version 2 and version 3 gearboxes, though gear ratios and tolerances differ between manufacturers. Compare against your current spur gear before fitting, and browse our airsoft accessories for matching internals.

Fitting and shimming

Every gear swap needs correct shimming for smooth, reliable running. If you would rather leave it to a technician, our Kent repair workshop can strip, fit and shim the gearbox.

Who it suits

Perfect for tinkerers, spares kits and budget repairs where a full new gear set is overkill.

Frequently asked questions

Is this a full gear set?

No. This is the spur gear only. If you need the matching sector and bevel gears, check our other boneyard gear listings or a full retail gear set.

Which gearbox does it fit?

AEG spur gears commonly suit version 2 and version 3 gearboxes, but ratios and tolerances vary by brand. Always compare against your existing gear before fitting.

What condition is it in?

It is a B-Grade boneyard part. It is used or salvaged and may show wear on the teeth. It is sold as a spare or for repair with no warranty.

Should I shim after fitting?

Yes. Any gear swap needs correct shimming to run quietly and reliably. If you are unsure, our Kent workshop can build and shim the gearbox for you.

Is it returnable?

Boneyard parts are sold as-is with no warranty. Please inspect and test the gear before use, as salvage spares are not covered by standard returns.
