JeffTron LEVIATHAN V2 Optical (rear wired) plus CNC FLAT Trigger – Black

JeffTron Leviathan V2 Optical with CNC Retro Arms Trigger
Leviathan V2 Optical is an electronic ETU unit with Bluetooth, designed to be installed in gearbox V2 and V2.5 based on the TM standard. Thanks to its optical sensors for shot detection and fire selector position, and an ultra-short switch (just 0.13 mm), it enables a precise hair trigger mode. The Real Feel Trigger System (RFTS) simulates realistic trigger resistance using a spring and provides trigger reset after each shot. You can configure firing modes, rate of fire, active braking, pre-cocking, virtual magazine, and more in real time using the JeffTron app. The input and output ports allow connection of accessories such as flashlights, electric magazines, or an empty magazine sensor. The unit is coated with conformal lacquer. It supports high-RoF setups including DSG gearsets and is ready for Brushless motors like Warhead. All changes made in the app are saved instantly to the unit’s memory. Additionally, the unit comes with a CNC aluminum trigger from Retro Arms featuring an adjustable screw for pre-travel and stylish design.
