Specna Arms – M80 Main Spring
This is an AEG gearbox main spring, and it is the major component that determines your gun’s power. The precise output varies from gun to gun and gearbox to gearbox because of variances in dimensions, components (such as bearing piston guides), compression (the quality of your air seal), and barrel and hop combination.
These are typically utilized for downgrades, when it’s necessary to bring a firearm operating hot below the permissible limit (particularly if your air seal is nearly flawless). Do not hesitate to inquire if you need help choosing which spring to use.
Because of the force dissipation caused by their non-linear design, these springs will last longer and experience fewer breaks.
