What does II. quality mean?
Products in the second quality category are 100% functional, but they may have a minor defect that does not affect the functionality of the product itself. Each product is inspected and only then released for sale.
All defects are individually mentioned for each product.
The products of the second quality category also come with a 2-year warranty.
The Rapax RMS series (Rapax Modular Spring) delivers top-tier upgrade springs in three power variants—2+J, 3+J, and 4+J—so you can customize your rifle exactly to your needs and field limits.
Key Features:
Universal Compatibility: All RMS springs have a 13mm outer diameter, perfectly fitting popular sniper platforms like Silverback SRS, TAC41, Novritsch SSG10/24/96, Modify Scout, and many more.
Modular Power Adjustment: Every spring comes with two 4mm PETG spacers, making it easy to fine-tune your FPS/Joule output for your field’s regulations.
Durability & Long Lifespan: Made from high-quality spring wire and specially tempered for minimal power loss and maximum longevity.
Silent Operation: Tight tolerances and an electrically coated surface minimize the classic "twang" sound for stealthier shots.
Easy Installation: Shorter design than other series for easier installation—even for beginners—and ideal compatibility with heavy pistons.
Anti-corrosion Coating: The electric coating prevents rust and ensures smooth movement on the spring guide.
Why Choose Rapax RMS?
Precise Tuning – Handmade in Europe with tight tolerances, each spring lets you adjust power easily with included spacers.
Universal Use – Great for casual upgraders and advanced players who demand maximum performance and quiet operation.
Optimized for Heavy BBs – Always measure with heavier BBs and adjust your hop-up for best results.
Available in Three Power Levels:
2+J: For reliable power and easy bolt pull.
3+J: The ideal balance between higher power and manageable effort, with quieter shots.
4+J: Maximum performance for long barrels and experienced players wanting the ultimate in power.
Tip: For G-Spec (short barrel) rifles, a stronger spring may be needed to reach the same power as longer-barreled models. Always use quality grease on the spring and guide for smoother operation and longer life.
Upgrade your airsoft sniper experience with Rapax RMS springs—power, silence, reliability, and durability, all in one package!
