Reliable Polycarbonate Piston for V2 Gearboxes

The Guarder Polycarbonate AEG Piston is a full teeth economy piston built for Version 2 airsoft AEG gearboxes. Moulded from tough polycarbonate, it delivers dependable cycling across a wide range of M4, MP5 and G3 style electric replicas without the cost of a full CNC part.

Full Teeth Design

This is the full teeth version, supplied without the last steel gear tooth for broad compatibility across standard V2 setups. Full tooth engagement spreads the load across the sector gear for smooth, consistent shots and predictable feeding.

Light and Shock Resistant

Polycarbonate keeps weight low for a snappier trigger response while shrugging off the repeated impact of firing. It is an ideal replacement during a service, or a sensible upgrade when refreshing a tired gearbox.

Fitting Made Easy in Kent

Gearbox work demands precision. We strongly recommend this piston is installed by an experienced technician, as incorrect fitting can cause damage not covered by warranty. Our in-house airsoft repair and Tech-It service can fit it for you. Browse more airsoft accessories to complete your build.

Frequently asked questions

Which gearboxes does this piston fit?

It is designed for Version 2 (V2) AEG gearboxes, which covers most M4, MP5, G3 and similar electric airsoft replicas. Always check your gearbox version before ordering.

Why is it called the economy version?

This full teeth piston is supplied without the last steel gear tooth. It offers dependable performance at a lower price than a steel-toothed or full CNC piston, making it ideal for standard builds.

Can I fit this myself?

We recommend fitting by an experienced or qualified airsoft technician. Incorrect installation can cause damage or product failure that is not covered by warranty.

Do you offer a fitting service?

Yes. Our in-house Tech-It upgrade, downgrade and maintenance service can fit this piston for most airsoft rifles. Contact the store for details.

Is polycarbonate strong enough for upgrades?

Polycarbonate is light and shock resistant, giving a fast trigger response. For very high tension spring setups a steel-toothed piston is usually recommended, so match the part to your build.
