Overview

Product Overview

The Laylax Prometheus Non-Linear AEG Upgrade Spring MS120 (Emerald) is a premium, high-performance internal power component expertly engineered to step up muzzle velocity and mechanical efficiency within standard Airsoft Electric Gun (AEG) gearboxes. Utilizing an advanced non-linear, variable-pitch coil configuration, this tuning spring is designed to wrap loosely at one end and tightly at the other. This smart architecture drastically reduces the initial rotational strain on your motor and gear teeth at the start of the compression stroke, delivering a smoother trigger break, lessened battery drain, and lower shock impact on the gearbox shell. The robust MS120 rating delivers a firm power upgrade, typically hitting target velocities around 370 to 400 FPS depending on the airtightness and compression efficiency of your cylinder assembly. Crafted from top-tier, oil-tempered steel wire and finished with a distinct Emerald color-coded protective layer for instantaneous tension identification on the workbench, this upgrade part gives commercial repair shops, custom gunsmiths, and retail stockists a reliable, elite-tier performance component.

Legal Information

iWholesales Ltd is a trade-only supplier ofAirsoft recreational equipment. Airsoft is a popular, non-lethal sporting hobby in the UK, legally and safely categorized alongside common activities like paintball and gel blasting.

1. A Safe & Regulated Hobby
  • Recreational Nature: Airsoft is an organized sporting activity focused on teamwork and target play, much like paintball.
  • Safety Tested: These items are engineered to discharge lightweight 6mm plastic pellets that are non-lethal and designed specifically for hobbyist use.
  • Legal Status: Under the Firearms Act 1968 (Section 57A), airsoft products are not considered firearms because they operate at very low energy levels.
2. Muzzle Energy & Safety Limits

To ensure these items remain safe for recreational play, they strictly follow the kinetic energy limits set by UK law:

  • Fully Automatic Models: These are capped at 1.3 Joules.
  • Single Shot Models: These are capped at 2.5 Joules.
  • Toy-Like Characteristics: Because they fire only plastic or part-plastic spherical missiles (max 8mm diameter) at these low energies, they are legally recognized as safe recreational tools.
3. Restricted Professional Ecosystem (B2B)

While individual buyers at retail shops must provide proof of "Defense" (such as a skirmisher membership) under the VCRA Act, iWholesales operates at a higher professional tier:
