Rapax RMS 2+J airsoft spring for Silverback SRS/TAC41, Novritsch SSG 10/24/96, upgraded VSR10 with 9mm spring guide, …

RMS stands for Rapax Modular spring.

All RMS springs come with two PETG printed spacers included in package. 2x4mm so you can adjust FPS/J according to your field limits.

RMS 2+J airsoft spring is 13mm outer diameter, so they fit all above mentioned sniper replicas.

We remind you that J is measuring just with heavy bb´s and not with 0.2. Please adjust hop-up for best flight path before measuring.

The difference from light pull series is in its length (considerably shorter than light pull series), slightly harder pull, but increased silent shots. Electrically coated to prevent rust which gives a more smooth operation on the spring guide. Rapax Modular Springs are easy to install.

All RMS 2+J airsoft springs are the same length, use the same material, have the same number of coils, ect.

Spring wire, used for production of our springs is of the highest quality, ensuring a prolonged period of usage compared to other springs. So far tests have proven more than 10.000 shots with one spring without losing strength.

We use spring tempering process in a way to guarantee a long lifetime and very small FPS/Joule loss over time.

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

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