Features

  • Easy installation inside the gearbox version V3 by Tokyo Marui standard
  • It uses optical sensor actuated by sector gear cam for perfect semi and full auto fire timing
  • For fire selector position is used optical sensor too - it works with sticker provided with Leviathan
  • Trigger optical sensor with foams can make great hair trigger mod
  • Unique real feel trigger system (RFTS), spring simulates trigger feeling like in the real gun. It adds secondary resistance with release after the fire. Feeling is comparable to shooting with a real AK74
  • Thanks to advanced electronics, Leviathan - V3 can be used with any common gearbox upgrade and gun rate of fire
  • Completely made wiring allows the fastest and the easiest installation into the gun, it is long enough for all kind of weapons with battery placed in front or above the gearbox. No soldering is needed
  • Board covered by conformal coating, it protect Leviathan - V3 against damage from water
The Leviathan - V3 optical is one of the most advanced ETU (electronic trigger unit) on the market.
It has all optical sensors for better handling and durability.
Built-in wireless communication for quick setup using iOS or Android smartphones!
Foam on the trigger makes great hair trigger mode.
Unique Real feel trigger system (RFTS), spring simulates trigger resistance like in the real AK74.
It adds secondary resistance with release after the fire. RFTS was designed by professional gunsmith for more realistic feel from shooting.
External input port and output pads serves for custom accessories.
Real time response for change settings -> immediately test result.
Easy installation into the gearbox instead of the original trigger contacts.
Completely made wiring allows the fastest and the easiest installation into the gun. No soldering is needed.
New functions are for free for every user via online update.

Main Functions:

  • Adds new shooting modes independent for every position on the fire selector (SAFE - SEMI - AUTO)
  • Three adjustable bursts (range 2 - 20 shots)
  • It preserves empty magazine detection like the original gun
  • Rate of fire can be reduce to 40%. It add breaks between shots to reduce RoF. It gives fast trigger response even with very low rate of fire, just like in a real gun
  • Adjustable strength active braking (can be disabled)
  • Pre-cocking function for instant shot on SEMI fire
  • Delay between shots adds time in which isn't possible to shoot, it simulates the delay from gun reload or recoil (range 0,1 - 4,0 seconds)
  • Electronic fuse set sensitivity for high current detection to avoid any damage if something goes wrong
  • Low battery indication for 2S - 4S li-pol and 3S - 4S li-fe
  • Virtual magazine simulates low capacity magazines, it will force the gun to stop shooting when it reach 0. There can be set warning after shot before empty magazine and how it will be reloaded
  • On the board is input port for controlling external devices or Leviathan and output pads for powering the hop-up chamber BBs illumination, powering electric magazine, flashlight, etc.
  • Statistics screen shows shooting output with cycle timing, motor current consumption, rate of fire and temperatures. It allows you to do fine-tune gearbox upgrade
  • Application shows actual battery voltage value. Color lines indicates battery charge status where green is OK, orange will warn after each shot and red will not allow to shoot
  • User can save multiple settings under profiles
  • Update function fixes bugs and adds new features to the device
  • There are three shot counters. Total count every shot during the device lifetime. User counter can be reset by user anytime. Power-up counter is reset by battery connection

  • Semi/BurstX: short trigger pull fires single shot, long trigger pull fires burst.
  • Binary trigger: it fires single shot when trigger is pulled and another single shot when is released.
  • BurstX: gun shoot burst per trigger pull.
  • BurstX/BurstY: short trigger press fires burstX, long trigger press makes burstX+burstY fire.
  • BurstX/Full: short trigger press fires burstX, long trigger press makes auto fire.
  • Full: gun makes auto fire until releasing trigger.

"Excellent mosfet. Direct drop in, great options and features. I liked the ease of install and performance so much that I bought a second one to put in my other cyma ak I was originally planning on converting to HPA. 10/10

"My first experience with any kind of optical MOSFET

Very familiar with the internals of a gearbox and have been teching for years installing various in-line Mosfets from gate.

That being said I'm extremely happy with the Leviathan!

Easy to install, no modifications required to the gearbox for krytac but you will lose the ability to hold the mock bolt back for hop up adjustment.

The Mosfet itself has an area very clearly defined which can be removed to fit in the Krytac shell. Once that area is trimmed it is absolutely drop-in

The first game I played with my LVOA was a night game and I fired around 2000 shots, towards the end of the night the trigger seemed to be rubbing on something mechanically. I had made it a hair trigger using the included trigger and set screw and it was just barely past the RFTS Metal clip which is there to simulate the feel of a real trigger

After disassembling the gearbox I noticed that the RFTS metal clip was slightly conflicting with the trigger itself. As I had no need for it anyways I carefully removed it from the circuit board. It has no electronics connected and pulling it out does no damage to the board

Used it again today and put another 3000 shots through the rifle with absolutely no problems whatsoever. I will be installing The same Mosfet in my krytac PDW but I will be removing the RFTS clip before installation.

The app is super easy to use and the Bluetooth feature is amazing! Definitely highly recommend especially if you're dropping this in a krytac

One note, I wasn't sure whether to take the metal band that contacts the stock trigger off of the selector plate. I looked online everywhere and could not find any information about it.

I personally removed the metal band from the selector plate before applying the sticker. Everything works as it should without the metal band in place.

"I LOVE this thing, it is totally worth the money and I would absolutely buy it if you get the chance.

Pros: TONS of adjustable features (all of which are accessed through the app.)
Very straight forward install.
If something isn't working the MOSFET will tell you through the app.

Cons: N/A

Just make sure you read the instructions, they will explain everything you need to know.
