Laylax Prometheus Non-Linear AEG Airsoft Upgrade Spring MS120 (Emerald)
Laylax Prometheus Non-Linear AEG Airsoft Upgrade Spring MS120 (Emerald) is a performance AEG mainspring designed to bring your build to an MS120 power level (site limits depending), using a non-linear (progressive) coil design for smoother compression and more stable cycling. It’s a strong option for skirmishers upgrading a standard AEG for outdoor performance or refreshing a tired spring to restore consistency—when installed and chrono’d correctly.
Tune your AEG properly with the Laylax Prometheus Non-Linear AEG Airsoft Upgrade Spring MS120 (Aqua). The mainspring is the core of an AEG’s power output, and Prometheus (Laylax) springs are a popular choice for players who want dependable quality and consistent results. The non-linear spring design uses progressive coil spacing to help deliver smoother compression through the gearbox cycle, supporting stable operation when paired with a well-built setup.
Rated at MS120, this spring is aimed at players who want a noticeable step up in power for outdoor skirmishes, longer engagement distances, or performance-focused builds. Keep in mind that final FPS will vary depending on your cylinder volume, barrel length, air seal, and overall build—so it’s essential to chrono after installation to ensure you remain within your site’s limits.
