Rapax Power-Up Rings for 9mm Spring Guides

Airsoft Sniper Spring Spacers for Precise FPS & Joule Adjustment

Fine-tune your airsoft sniper rifle with the Rapax Power-Up Rings, a set of precision steel spring spacers designed for 9mm spring guides.

By increasing spring preload, these spacers allow you to make controlled adjustments to your rifle's FPS and Joule output without immediately changing the main spring. With 4mm, 6mm and 8mm spacers included, they can be used individually or combined to give you greater control over your sniper setup.

Ideal for Silverback TAC-41, Silverback SRS, Novritsch SSG10, SSG24, SSG96 and compatible upgraded VSR-10 sniper rifles.

Why Use Rapax Power-Up Rings?

Different barrels, pistons, springs and air seals can produce different power levels, even when using the same spring.

Rapax Power-Up Rings allow you to:

• Fine-tune FPS and Joule output
• Increase spring preload without replacing the spring
• Make smaller, controlled power adjustments
• Compensate for differences between sniper rifle builds
• Tune your setup towards your required power level

Simply add or remove spacers until the desired output is achieved.

What's Included?

Each set contains 3 steel Power-Up Rings:

• 1 x 4mm spacer
• 1 x 6mm spacer
• 1 x 8mm spacer

The rings can be used individually or stacked together for additional adjustment.

Compatibility

Designed for 9mm spring guides, Rapax Power-Up Rings are compatible with many popular airsoft sniper platforms and upgrade systems, including:

• Silverback TAC-41
• Silverback SRS
• Novritsch SSG10
• Novritsch SSG24
• Novritsch SSG96
• Stalker Scorpion piston setups
• W.A.S.P. piston setups
• Compatible upgraded VSR-10 systems
• Other aftermarket 9mm spring guides

Premium Steel Construction

Unlike lightweight plastic spacers, Rapax Power-Up Rings are manufactured from high-grade steel for excellent durability.

The steel is chemically treated using a real-firearm-style bluing process, providing additional resistance against corrosion and wear.

How Do Rapax Power-Up Rings Work?

Install one or more rings onto the 9mm spring guide to increase compression of the mainspring. Increased preload can raise the rifle's FPS and Joule output.

Need to reduce the power again? Simply remove one or more spacers.

Always chronograph the rifle after changing the spacer configuration, as the exact increase will depend on the spring, barrel length, piston weight, air seal and overall rifle setup.
