Product details

RMS 3+ J spring- SRS/SSG/VSR (aps2 standard, 13mm spring, 9MM SPRING GUIDE)

RMS stands for Rapax Modular spring.

Rapax Modular Spring series is made with same quality standards as the Light Pull series springs. With durability and quality there made to give you the best sniper experience. The difference from light pull series is in its length (considerably shorter than light pull series), slightly harder pull, but increased silent shots. Also RMS springs are electrically coated to prevent rust which gives a more smooth operation on the spring guide.

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

All springs are the same length, use the same material, have the same number of coils, ect.

Spring wire used for Rapax springs production is of the highest quality spring wire, ensuring a prolonged period of usage compared to other springs.

Tempering of these springs is made in a way to guarantee a long lifetime and very small FPS/Joule loss over time.

Springs are made in tight tolerances regarding diameter, they prevent the “twang” sound in airsoft sniper replicas.

Note: Gspec versions of replicas, the one with 300mm barrel always need harder spring to achieve same J/FPS than longer barrels.
