The Jefftron Leviathan NGRS Optical is an advanced Electronic Trigger Unit (ETU) specifically engineered for Tokyo Marui Next Generation Recoil Shock (NGRS) platforms. This rear-wired unit replaces the original trigger contacts, integrating into the gearbox to provide instant trigger response and wireless programming via the Leviathan smartphone app. Unlike other versions, the NGRS model includes the Real Feel Trigger System (RFTS) as an integrated feature, utilizing a spring mechanism to simulate the tactile resistance and reset of a real firearm. It preserves critical NGRS functionality, including empty magazine detection, while offering a suite of professional upgrades like pre-cocking, active braking, and high-voltage support up to 17V. Here at Northmark Vault, we prefer this NGRS MOSFET due to the added realism of the RFTS feature. This brings another added point of realism to add to the simulated recoil and reload function. On top of that, if any issues arise in the field, a vast majority of the time the unit will let you know an error has occurred instead of self-destructing the entire NGRS replica. If that wasn’t enough to sell you on this product, unlike other options on the market, there is no need for an extra Bluetooth or plug-in device for programming. All programming can be accessed with any Bluetooth-capable device! 
 

Technical Specifications:

  • Hybrid Sensor Suite: Combines high-resolution optical sensors for cycle and selector detection with a high-durability tactile trigger switch.
  • Integrated RFTS: Features a built-in Real Feel Trigger System designed to mimic the weight and break of a real firearm trigger.
  • Wireless Connectivity: Built-in Bluetooth for real-time adjustments and firmware updates via the official Leviathan App.
  • Hair Trigger Performance: Equipped with a tactile switch featuring an ultra-short 0.13mm travel for rapid-fire engagement.
  • Custom Fire Modes: Supports independent programming for every selector position, including Semi, Auto, Binary Trigger, and adjustable Burst (2–20 rounds).
  • NGRS Feature Support: Retains the original bolt catch sensor functionality for empty magazine detection and automatic firing cutoff.
  • Protection and Diagnostics: Active monitoring of battery voltage (8.4V–17V), current draw, and temperature with an electronic fuse to prevent internal damage.
  • High-Quality Rear Wiring: Pre-soldered AWG16 power wires and AWG22 signal wires with thin MPPE insulation, designed for buffer tube and stock battery placement.
