icon Description

C-TECH NGRS F350 Gearbox Spring (M110)

Gives approximately 350 FPS depending on your air seal. We recommend upgrading the gears, piston and motor as well for the best performance and reliability.

C-TECH Next Gen Upgrade Springs have been specially developed for the Tokyo Marui Next Generation Recoil Shock Series. Each high carbon steel spring has been load tested and heat treated to reduce the production variance to 3% and finished with grounds ends for consistency.

Our rating system has been designed to make it easier to select the appropriate spring for your desired power. The number in the rating translates to the muzzle velocity (fps/feet per second) of a 0.2g BB using a Prometheus bearing spring guide and Tokyo Marui cylinder, cylinder head, piston, piston head, nozzle, hop unit and inner barrel. Please note that the final muzzle energy achieved will vary depending on what parts are fitted.

Finished in 3 different colours for easy identification.
