MechLabs XX-Mod HPA Engine
The MechLabs XX-Mod HPA Engine is a fully mechanical, drop-in HPA conversion system designed to replace a standard AEG gearbox. Built from CNC-milled Series 6 aluminum, the XX-Mod combines a modular design with precision adjustment systems for flexible installation, performance tuning, and maintenance. Its mechanical, electronics-free design provides a waterproof HPA platform, while the adjustable XX-Mold Bolt and Air Bender system allow users to fine-tune nozzle positioning, air-cycle timing, and rate of fire.
