LEVIATHAN NGRS Optical M4 (Rear Wiring)

JeffTron Leviathan NGRS Optical

Leviathan NGRS Optical is an electronic ETU with Bluetooth, designed for installation in the NGRS gearbox by Tokyo Marui. Thanks to optical sensors for shot detection and fire selector, plus an ultra-short switch (only 0.13 mm), it allows for realistic hair trigger mode. The Real Feel Trigger System (RFTS) with a spring simulates the trigger resistance of a real firearm and adds reset after firing. With the JeffTron app you can configure fire modes, RoF, active braking, pre-cocking, virtual magazine and more. The input/output ports support connecting external devices like flashlights, drum mags, or empty mag sensors. The unit is protected by conformal coating. It is compatible with the original bolt catch and retains the empty mag cut-off function. It's also fully ready for brushless motors like Warhead. All app settings are saved in real time directly to the unit.
