AirsoftPro AEG Progressive Spring

The AirsoftPro progressive spring is one of the key components affecting the performance of an airsoft gun. It is manufactured from the same type of SiCr spring steel used in popular Guarder springs. The progressive coil design reduces resistance during the initial compression phase and reaches maximum resistance only at full compression. This results in a smoother gearbox cycle while reducing stress on the motor, gears, and other drivetrain components. The spring has been tested through live firing, showing no measurable loss of length or performance even after 10,000 shots.

Key Features

Progressive Winding

The variable coil spacing reduces resistance at the beginning of compression, contributing to smoother gearbox operation.

Durable SiCr Material

Made from silicon-chromium alloy valve spring steel designed for long-term cyclic loading.

Long Service Life

Maintains its length and performance better than standard factory springs, even after thousands of shots.

Compatible with Most AEG Gearboxes

Suitable for Version 2, Version 3, and most other standard AEG gearbox designs.

Also Suitable for Manual SVD Rifles

Can also be used in manual SVD sniper rifles designed for springs of this power class.
