Valken ASL Complete Gearbox Upgrade

Looking to enhance your airsoft rifle’s performance while ensuring seamless compatibility? The Valken ASL Complete Gearbox is a precision-engineered upgrade designed specifically for rear-wired Valken ASL or Battle Machine M4 series airsoft guns. Crafted for durability and efficiency, this drop-in assembly replaces worn components without compromising your system’s reliability or speed.

Key Features
– Sturdy Metal Construction: Built with a reinforced metal alloy gearbox shell and 6mm polymer-coated metal bushings, this assembly withstands rigorous gameplay while minimizing wear on critical moving parts.
– Optimized Performance: Equipped with low-resistance wiring and an 18:1 ratio metal gear set, this upgrade delivers smooth operation and consistent power output, achieving an estimated 345–350 FPS for faster pellet velocities.
– Direct Fit Design: As a complete drop-in unit, it simplifies installation by replacing the entire rear-wired gearbox system—ideal for users seeking hassle-free upgrades over partial replacements.

Compatibility & Build Quality
Tailored for Valken ASL (excluding ASL+ models) and Battle Machine M4 series rifles only, this Version 2 gearbox ensures precise alignment with your gun’s specifications. The combination of metal alloy gears and polymer materials balances strength with lightweight design, reducing rotational friction for longer-lasting performance compared to standard plastic alternatives.

Installation Considerations
While designed as a direct replacement, minor adjustments may be required due to variations in individual gun builds. For optimal results, we recommend professional installation to guarantee proper alignment and function. Always verify local regulations before modifying airsoft equipment—this accessory is strictly for recreational use in paintball or airsoft scenarios.

Upgrade your rifle’s reliability and speed with the Valken ASL Complete Gearbox—engineered for serious players who demand precision and durability in every match.
