Lonex AEG FPS Tune-Up Non-Linear Spring (GG06-10)

Tune your compatible airsoft AEG’s spring setup with the Lonex FPS Tune-Up Non-Linear Spring. Steel construction, progressive coil spacing, and flat-ground ends make this a replacement option for a gearbox build or maintenance project.

Select the rating for your setup

Choose the rating you need from the available variants before ordering. Actual muzzle velocity depends on the selected spring, air seal, barrel, cylinder volume, BB weight, and installation; an M-rating alone does not guarantee a specific FPS.
