Specna Arms M130 Tuning Spring for AEG

The Specna Arms M130 Tuning Spring for AEG is a high-quality main spring for airsoft players who wish to fit their replica with a powerful and reliable internal upgrade. Manufactured from high-quality spring steel and finished with flat-ground ends, this tuning spring offers consistent performance and a long service life, even with intensive use.

Specna Arms is renowned for its high-quality internal parts and develops products suitable for both maintenance and performance-enhancing upgrades. The M130 Tuning Spring is designed for players who wish to create a powerful AEG build using durable and precision-manufactured components.

Designed for high-performance AEG builds

The main spring largely determines the force with which the piston is driven. In more powerful replicas, a high-quality spring is essential to maintain consistent performance and distribute the load evenly across the gearbox.

The Specna Arms M130 Tuning Spring is designed for players who want to upgrade their replica to a more powerful configuration or replace a worn-out main spring.

This makes this spring suitable for:

• Performance-oriented AEG builds.
• DMR projects (subject to regulations).
• Gearbox overhauls.
• Replacement of worn springs.

High-grade spring steel

The M130 is manufactured from high-quality steel that is particularly suitable for long-term use.

This choice of material offers several advantages:

• High wear resistance.
• Long-term maintenance of resilience.
• Reliable performance.
• Suitable for intensive use.

Thanks to its high-quality finish, the spring retains its properties throughout many firing cycles.

Flat-ground ends

A key quality feature of Specna Arms tuning springs is their flat-ground ends.

This ensures that the spring fits perfectly against the spring guide and piston, resulting in an even distribution of force during every compression.

This contributes to:

• A gearbox that operates smoothly.
• Less mechanical stress.
• Constant compression.
• Less unnecessary wear and tear on internal components.

Suitable for AEG upgrades

The Specna Arms M130 is designed for use in AEG replicas fitted with a suitable gearbox.

The ultimate performance of a replica is not determined solely by the spring. Factors such as the air seal, cylinder, nozzle, inner barrel and hop-up configuration also play an important role.

As a result, the same M130 spring can produce different results in different replicas.

Colour-coding for quick identification

The spring is fitted with a coloured tip, making it easy to identify which spring is fitted during maintenance or upgrades.

For airsoft technicians and players who regularly build or maintain different set-ups, this makes the work more organised.

Suitable for overhauls and maintenance

After prolonged use, a main spring may gradually lose its tension. It is therefore advisable to check the condition of the spring during a gearbox overhaul and to replace it if necessary.

The Specna Arms M130 is ideal for:

• Preventive maintenance.
• Complete gearbox overhauls.
• New AEG builds.
• Replacement of worn main springs.

Practical insights

A powerful main spring requires a gearbox that is designed to handle it. When fitting an M130 spring, it is advisable to also check the condition of the piston, gears, spring guide and bushings or bearings. A well-balanced internal configuration not only ensures better performance, but also extends the lifespan of the replica.

Thanks to the use of high-quality spring steel and its precision finish, the Specna Arms M130 provides a reliable foundation for players who wish to further optimise their AEG.

Frequently Asked Questions

Is this spring suitable for any AEG?
The spring is designed for AEG replicas, but always check that your gearbox is compatible with an M130 configuration.

What material is the spring made of?
The M130 Tuning Spring is made from high-quality spring steel, ensuring a long service life and consistent performance.

Why are the ends ground flat?
Flat-ground ends ensure an even load on the spring and help the gearbox to operate smoothly.

What is the coloured tip for?
The colour-coded marking makes it easy to quickly identify the spring’s tension during maintenance or upgrades.
