WYSHTECH Airsoft shows you how to adjust your KWA 2.5+ or VM4 gearbox so that it can work with a Jefftron Leviathan. The Leviathan - V2 optical is a high-tech ETU (electronic trigger unit) that enhances your shooting experience. It uses both optical and switch sensors to detect the trigger position and control the gearbox, making it more responsive and durable than traditional ETUs.
