RMS stands for Rapax Modular Spring.
The Rapax Modular Spring series is manufactured to the same quality standards as the Light Pull spring series—built for durability and performance to deliver the best sniper experience. The difference from the Light Pull series is its shorter length (significantly shorter than Light Pull), slightly stronger pull, and more silent operation. Additionally, RMS springs are electroplated to prevent corrosion, ensuring smoother movement within the spring guide.
All RMS springs come with two printed PETG spacers included in the package: 4mm and 6mm, allowing you to adjust FPS/J according to your field limits.
All springs share the same length, material, number of coils, etc.
The wire used in Rapax springs is of the highest quality, ensuring a significantly longer service life compared to other springs.
The heat treatment of these springs ensures a long lifespan with minimal FPS/Joule loss over time.
Springs are manufactured with tight tolerances on diameter to eliminate the "twang" sound common in airsoft sniper replicas.
Note: For G-spec replicas with a 300mm barrel, a stiffer spring is always required to achieve the same J/FPS as longer barrels.
