Rebel Precision AEG Spring – M120 is a mid-to-higher power mainspring designed for AEG gearboxes, ideal for players and techs tuning an AEG to a specific FPS/Joule target (always subject to site limits). It’s a popular choice for outdoor skirmish builds, “hotter” setups, or as a fresh replacement spring when rebuilding a gearbox for consistent performance.
Tune your AEG for stronger outdoor performance with the Rebel Precision AEG Spring – M120. Whether you’re building a rifle for longer engagement distances, replacing a tired spring, or aiming for a specific chrono result, the mainspring is one of the most important parts in your setup—and the M120 rating is a go-to option for many skirmish-focused builds.
An M120 spring is commonly used when you want a bit more output than a standard setup, especially when paired with good compression parts and a solid air seal for consistent shot-to-shot results. It’s a straightforward upgrade for techs and DIY builders looking to balance power, efficiency, and reliability—just be sure to chrono your replica and stay within your local site rules.
