Precision CNC Spring Guide

The Maxx Model CNC spring guide is machined from stainless steel and aluminium to exacting tolerances, replacing the softer plastic guide found in many stock Version 2 gearboxes. A rigid, precisely made guide keeps your spring aligned and compressing evenly, which is the foundation of consistent, repeatable power.

Made for the Version 2 Gearbox

This guide is built specifically for Version 2 gearbox airsoft rifles, so it slots into the vast majority of M4, MP5 and similar AEG builds during a rebuild or upgrade. Its M5 x 0.80 internal thread matches standard fitment.

Verified Dimensions

Precision matters inside a gearbox. This guide runs a 16mm hub, a 10.8mm shaft measuring 44.5mm long and an overall length of 51.5mm. Those figures mean it drops in cleanly and holds the spring true even under heavier springs where cheaper guides flex.

Build It Better

Combine it with fresh internals from our airsoft accessories range, or have our Tech-It team fit it as part of a full gearbox service.

Bought from the specialists: our in-house workshop in Rochester, Kent can service, repair and upgrade your kit. See our airsoft gun repair and servicing.

Frequently asked questions

Which gearbox does this fit?

It is designed for Version 2 gearbox airsoft rifles, the most common AEG platform used in M4, MP5 and similar builds.

What are the key dimensions?

The hub outer diameter is 16mm, the shaft is 10.8mm across and 44.5mm long, and the overall length is 51.5mm with an M5 x 0.80 internal thread.

Why upgrade the spring guide?

A rigid steel and aluminium guide keeps the spring aligned and compressing evenly, which supports more consistent FPS and reduces flex compared with plastic guides under heavy springs.

Is it a direct replacement?

Yes. It uses standard Version 2 dimensions and an M5 x 0.80 thread, so it fits in place of the stock guide during a gearbox rebuild.

Do I need a licence to buy this?

No. This is an internal gearbox component, not a firearm, so no UKARA defence and no age verification are needed.
