Laylax Prometheus Non-Linear AEG Upgrade Spring MS110 (Aqua)

Striking the perfect balance between high muzzle velocity and reliable mechanical performance is essential for any field-ready AEG setup. The LayLax Prometheus Non-Linear AEG Upgrade Spring MS110 (Aqua) combines elite Japanese manufacturing with an irregular pitch design to deliver smooth compression, prolonged tension life, and dependable velocity output.

Irregular Pitch (Non-Linear) Mechanical Advantage

Traditional linear springs compress with uniform resistance throughout the piston stroke, forcing your motor and bevel gear to overcome peak mechanical force immediately upon pick-up. In contrast, the irregular pitch geometry of the Prometheus non-linear spring features unevenly spaced coils. The tighter coils compress first during the initial cycle phase, significantly easing the startup load on your motor, battery, and gear set. The broader coils then compress to store full kinetic energy, resulting in a fluid gearbox cycle and lower battery amp draw.

High-Tensile Steel & Aqua Color Coding

Manufactured from high-grade oil-tempered steel wire, the MS110 main spring undergoes rigorous stress-relief treatments to prevent spring fatigue and sag over extended use. While standard springs lose length and drop FPS after heavy skirmishing, Prometheus non-linear springs retain their tension and structural integrity for thousands of rounds. Designed for easy workshop identification, this spring features a durable aqua coating that allows techers to identify the MS110 power rating at a glance.

The Standard Power Choice for Field Play

Designated as an "MS110" rating (yielding approximately ~350 to ~380 FPS on a standard 0.20g BB setup depending on cylinder volume and hop-up air seal), this spring is widely considered the ideal power output for standard outdoor airsoft field limits. Upgrading to LayLax ensures reliable power delivery, flatter trajectories, and smooth, efficient gearbox cycling.

Key Features & Technical Benefits:

• Irregular Pitch (Non-Linear) Design: Reduces motor startup strain and gear teeth stress during pick-up.

• MS110 Power Rating (~350–380 FPS): Ideal power output for standard outdoor field velocity limits.

• Oil-Tempered High-Tensile Steel: Superior fatigue resistance prevents spring sag and FPS loss over time.

• Aqua Color-Coded Finish: Distinctive aqua coating allows fast identification of spring rating.

• Universal AEG Fitment: Compatible with standard Version 2, Version 3, Version 6, and quick-change AEG gearboxes.

Tech Tip: For maximum longevity, we recommend pairing this spring with a ball-bearing spring guide to eliminate spring torsion and ensure a smooth power delivery.
