MechLabs XX-Mod Fully Mechanical HPA Engine - Purple

The XX-Mod represents the next evolution of mechanical HPA technology — a platform shaped by real feedback from the global airsoft community. Every element of its design reflects the needs of players and technicians alike, delivering a system that combines modularity with precision to achieve unmatched expandability and adaptability. Whether for performance tuning, platform conversion, or field maintenance, the XX-Mod is engineered to evolve with you.

Built from CNC-milled Aluminium Series 6, the XX-Mod achieves the perfect balance between lightweight construction and structural strength. As a drop-in kit, it allows you to replace your standard AEG gearbox with zero hassle, transforming your airsoft gun into a fully mechanical HPA system in minutes. Its modular block design allows for easy and intuitive swapping between sections, adapting the engine seamlessly to different setups or playstyles. Each block connects through a precision lock-fit interface, ensuring perfect mechanical alignment and repeatable assembly.

To guarantee compatibility across all receiver types, the XX-Mod incorporates a 3-axis XYZ alignment system, allowing micro-adjustments for perfect fit and optimal air-path precision.
In addition, the XX-Mod is a fully mechanical unit with zero electronics, making the engine completely waterproof. It can operate reliably in wet weather conditions and will continue to function even when fully submerged underwater.
