JeffTron LEVIATHAN ASG EVO 3 Optical plus Anti-Reversal Latch

JeffTron Leviathan ASG EVO 3 Optical
Leviathan ASG EVO 3 Optical is an ETU unit with Bluetooth, designed for installation in the EVO gearbox from ASG. Thanks to optical sensors for shot detection and fire selector, and the option to add a foam pad, it allows configuration of a true hair trigger mode. With the JeffTron app, you can live-configure firing modes (individually per selector position), RoF, active braking, pre-cocking (after installing CNC latch), virtual magazine and more. Input and output ports support external accessories like flashlights, electric magazines, or empty mag sensors. The unit is protected with conformal coating. It’s compatible with high-speed builds including DSG gears (with CNC latch), and is fully prepared for brushless motors like Warhead. All changes made in the app are saved in real-time to the unit’s memory. The unit retains the bolt catch function and shot interruption on empty mag as on original ASG ECU, and this feature can now be easily disabled via the app.
