Genuine ASG EVO spring

This is the genuine ASG M95 upgrade spring made for the CZ Scorpion EVO 3 A1. It is manufactured from hardened steel with a bronze finish and is designed to drop straight into the EVO gearbox with no additional adaptation, guaranteeing clean integration with the original internals.

Precise power tuning

The M95 rating delivers approximately 320 fps on 0.20g BBs, around 0.95 joule, placing it in the 0.5 to 1 joule band. That makes it an ideal spring for setting your rifle to a stable, site-legal power level, which is especially useful for CQB fields that enforce strict joule limits. Exact output will vary with barrel length, cylinder volume and air seal.

Wider gearbox compatibility

While it is engineered for the Scorpion EVO 3 A1, this spring is also compatible with standard Version 2 (V2) and Version 3 (V3) gearboxes, so it is a handy tuning spring for a range of AEGs, not just the EVO.

Fitting and chrono

Changing a spring means opening the gearbox, so basic AEG knowledge helps. If you would prefer, our airsoft repair workshop in Kent can fit the spring and chrono the rifle to confirm it is on the limit. Browse more internals in our airsoft accessories range.

Frequently asked questions

What power does the M95 spring give?

As a guide, the M95 delivers roughly 320 fps on 0.20g BBs, around 0.95 joule, though actual output depends on your barrel length, cylinder and air seal. It sits in the 0.5 to 1 joule band, making it useful for tuning down to site or CQB limits.

Does it only fit the Scorpion EVO 3 A1?

It is designed specifically for the Scorpion EVO 3 A1 gearbox and drops straight in with no extra adaptation, but it is also compatible with standard Version 2 and Version 3 gearboxes.

Is this a downgrade or an upgrade spring?

It can be either depending on your current setup. Many players use the M95 to downgrade an out of the box rifle to a stable, site-legal power level, while others use it to reach a specific target output.

Is fitting difficult?

Fitting a spring means disassembling the gearbox, so some knowledge of AEG internals is needed. If you would rather not open the gearbox, our workshop can fit it and chrono the rifle for you.

Is this a genuine ASG part?

Yes, this is a genuine ASG spring made specifically for the Scorpion EVO 3 A1 platform, not a generic aftermarket spring.
