Precisely tune the power of your AEG with a strong, reliable spring.

The non-linear design reduces piston stress, increasing durability. Excellent Lonex build quality ensures a long life of consistent FPS (feet per second),  an essential precursor to accuracy.

Buy a new spring to raise or lower your power output in compliance with your site’s power limits. If necessary, you can fine tune your FPS further by short-stroking the sector gear and piston.

Material: Alloy steel wire

Works well with:

Lonex Ball Bearing Spring Guide - The ball bearing allows the spring to twist, alleviating stress and improving FPS, power consistency and longevity.
