JeffTron LEVIATHAN V3 Optical plus Trigger Adjustment Module – Black

JeffTron Leviathan V3 Optical with trigger adjustment module
Leviathan V3 Optical is an ETU unit with Bluetooth designed for installation in a gearbox V3 following the TM standard. Thanks to optical sensors for detecting shots and fire selector position, and the option to insert a foam pad, you can configure a realistic hair trigger mode. The Real Feel Trigger System (RFTS) uses a spring to simulate real trigger resistance and adds a reset after each shot — developed in collaboration with gunsmiths. The JeffTron app allows real-time configuration of firing modes, rate of fire, active brake, pre-cocking, virtual magazine, and more. Input and output ports support accessories like flashlights, electric magazines, or empty mag sensors. The unit is protected with conformal coating and supports high-RoF builds including DSG gears. It’s fully ready for Brushless motors such as Warhead. All app changes are saved to the unit in real-time. This version also includes a trigger adjustment module for Single-Stage (ideal for competitive shooting) and Two-Stage (realistic trigger break simulation). The module is 3D-printed and made specifically for gearbox V3 with Leviathan, providing an even more realistic trigger experience than RFTS alone.
