The KWA RM4 Series AEG3 M120 spring is specially made to work with the KWA RM4 Kinetic Feedback System (KFS), and is made of hardened spring steel. Â It fits in both the original RM4 PTS Scout and CQB models as well as the new rear-wired RM4A1, and is rated at around 390-410 FPS.
An essential feature on the new rear-wired RM4A1 as well the new RM4 AEG3 variants is the addition of spring quick-change abilities, so you can easily move from the field to a CQB setting (or vice versa) with minimal effort.
Whether you need to refresh your RM4 or you to alter the FPS on your RM4 CQB, you can definitely consider this a must-have.
