RMS Modular Spring 3+ J Spring SRS / TAC41 / SSG / VSR


A high-quality spring machined in Europe by Rapax for SRS, VSR, TAC41, SSG, and similar sniper rifle replicas.
Characterized by a slightly harder pull but suppressed mechanical action, the 13mm outer diameter spring comes with two spacers and an approximal power of 3J. The 3D-printed spacers provide a non-invasive option to adjust FPS/Joule output.
The product is CNC coiled from high-quality wire, tempered, and furtherly electroplated. This technological process guarantees resistance to rust, reduction of friction, and negligible FPS/Joule loss over time.
