AEG Upgrade Springs

AEG upgrade springs are the main springs used in electric airsoft guns to adjust the muzzle velocity and power output of the replica. The stiffness of the spring determines how much energy the piston generates when compressing air in the cylinder, directly affecting the BB’s velocity.

Upgrade springs are available in different ratings such as M90, M100, M110, M120 and M130, allowing players to tune their AEG to match field limits or desired performance.

In this category you will find AEG upgrade springs for electric airsoft guns, suitable for gearbox upgrades, maintenance, and power tuning.
