RMS 2+/3+/4+ J Spring - SRS / SSG / VSR (APS2 standard, 13 mm spring)

RMS stands for Rapax Modular Spring.

The Rapax Modular Spring series is manufactured to the same quality standards as the Light Pull series springs. Built for durability and quality to provide you with the best sniper experience. The difference compared to the Light Pull series lies in its length (considerably shorter than the Light Pull series), slightly stronger pull, and a higher number of quiet shots. In addition, RMS springs are electro-coated to prevent oxidation, ensuring smoother operation on the spring guide.

All RMS springs come with two PETG printed spacers included in the package, 4 mm and 6 mm, allowing you to adjust FPS / J according to your field limits.

All springs have the same length, use the same material, and have the same number of coils, etc.

The spring wire used in the production of Rapax springs is of the highest quality, ensuring a longer service life compared to other springs.

The tempering of these springs is carried out in a way that guarantees a long lifespan and minimal FPS / Joule loss over time.

The springs are manufactured with tight diameter tolerances, preventing the "twang" sound in sniper airsoft replicas.

Note: G-Spec versions of replicas, which have a 300 mm inner barrel, always require a stronger spring to achieve the same J / FPS as longer barrels.
