Leviathan - NGRS parameters
- It is processor controlled mosfet with wireless communication.
- Device paramethers is changed with smartphone via application (Android and iOS).
- Device is fully integrated inside the gearbox instead of the original trigger contacts.
- It can be tted into these Tokyo Marui Next Generation guns: M4, SCAR, HK416, HK417.
- It has wires to stock (loose end), mini 40A fuse and deanT to solder after gun assembly.
- It adds new shooting modes, controls RoF, pre-cocking, active braking, virtual magazine,
input and output ports, electronic fuse, low battery indication, statistics...
- Usable for battery with max. 17 volts (max. lipol 4S 14,8V).
Safety warning
- Installation of this device into the gearbox requires advanced technician skills!
- Please read these informations before installing your device to prevent any damage.
- Short circuit or incorrectly connected battery will cause immediate damage to the de-
vice which is not covered by the warranty. It can lead to re or even battery explosion.
- Disconnect battery, when you aren‘t using the gun! Otherwise you will fully discharge
the battery. Because the device drains small amount of current from it all the time.
- Don‘t connect battery when gun pointing towards you, another person or an animal.
- Don‘t modify, repair, put into any kind of liquids or thermal shock the Leviathan.

Device overview
- Tactile trigger micro switch is in the red circ-
le, button travel is only 0.13mm.
- RFTS = Real Feel Trigger System was made
by professional gunsmith for more realistic
feel from shooting. This spring simulates
trigger resistance. You can bend its end to
change resistance.
- Pink micro switch detects empty magazine.
- Optical sensor for the sector gear is in the
green circle, it detects gear cam movement.
- Yellow reset button hold for 2s, password
is reset to 1234 after vibration from motor
(settings are reset too).
Optical sensor is for detection SAFE, SEMI
and AUTO position. It is shown in the red
circle. For its function is neccessary to pla-
ce sticker on the selector plate.

External ports
Input terminal
- Leviathan has 3 pads for connecting
external button, virtual reload or sensor.
- 3,1V is in the red area (for sensor only).
- Signal is in the yellow area.
- Negative pole is in the green area.
- External button connects on SIG and
GND pad (doesn‘t matter on polarity).
- In the app use interface „External input“
to activate desired function.
Output terminal
- Leviathan has 2 pads on the board
for powering hop-up LED illumination,
ashlight, laser, magazine motor etc.
- On the Positive pad is battery voltage
(in the red area).
- Negative pad from the motor is in the
green area, the power is fully driven
throuht the Leviathan microprocessor.
- In the app use interface „External out-
put“ to activate desired function.
- Some input functions activates output
terminal even on OFF status.
WARNING: Installation requires advanced soldering skills! Wires can‘t touch other pads
and components on the board. Damage to the Leviathan will void the warranty!

Insertion procedure of Leviathan-NGRS into the gearbox
1. Remove and open the gearbox according to the normal gun disassembly procedure.
2. Take out all the internals from the gearbox and clean the vaseline, oils after them.
3. Check the gearbox for edges. Grind for smooth surface to prevent Leviathan damage.
4. Take out these parts out of the gear-
box (not used with the Leviathan).
5. Remove other internals from gear-
box. Prepaired gearbox for installation.
6. Grind these 2 pins to at, it is nece-
ssary to t wiring inside the gearbox.
7. Make 2mm gap into the red area to
insert wiring through this gap.
Gearbox shell modication
Stock gearbox modicaion is necessary to t Leviathan wiring without damaging them
- see pictures 6 and 7.
Please skip this part, if you already bought CNC gearbox from Retroarms, because it
has enough room for the wiring.

9. Insert the Leviathan-NGRS instead of the original contacts:
- Check if the Leviathan-NGRS is laid at on the gearbox shell.
- Adjust the Leviathan position to the same distance from sector gear bearing (red circle).
- Use screws with washers from package and screw device to gearbox (white circles).
7. Keep in place transparent foil, it pre-
vents from short circuit through gearbox.
8. Unplug Leviathan top board from
the bottom - all jumpers at one time.

13. Wires under motor have to stick
on the wall. You can use hot glue to x
their position in the gearbox.
12. Place wires in order: blue, -battery,
-motor. Keep clear green hole for pin.
10. Make sure the screws doesn‘t stick
outside of the gearbox. If yes grind it.
11. Check if there are any parts contact
with the gearbox around the red area.
14. Overall view to the wiring in gearbox.
15. Stick 2 foams to the right gearbox
shell according this image (foams are
included in the package).
7
17. Carefully insert the trigger into
the gearbox. Trigger spring has to be
outside the gearbox.
16. Carefully plug top board into the
bottom. Watch for right jumpers position
otherwise Leviathan could be damaged.
18. Push the trigger spring into the
gearbox by screwdriver or pliers.
19. Lube the top part of the trigger by
small amount of vaseline (for RFTS).
20. Check sector gear height, it can‘t
touch the optical sensor or screw.
21. Insert the remaining parts into
the gearbox. Put together the gearbox
shell. Check if it ts perfectly together.

22. Assemble empty magazine
detection system and check its right
interaction with micro switch.
25. If you want functions on SAFE posi-
tion, cut the selector plate in red area.
Mechanical locking will be disabled.
23. Take out one of 12 stickers by pliers.
Do not touch the sticker by hand!
24. Clean selector plate by degreaser
and place sticker the to the white area.
26. Black wire bends back at the
bottom and lead both wires back.
27. Bend both motor connectors
exactly like on the picture.
Do not bend it to the other site!

28. Connect the black wire rst. Keep
in mind right motor polarity.
Motor has opposite position now.
29. If you want to use original battery
connector, cut wires in this place and
solder them to the connector.
30. Also you can use this Leviathan set
for T-plug connector.
31. Squeeze faston connector around
red wires with pliers and solder them.
32. Use lighter or hot air gun to shrink
tube around the spade connectors and
connect both of them to the fuse.
33. Shrink large tube around the fuse
and wires. Solder black and red wire to
the T-Plug connector.
KEEP IN MIND RIGHT POLARITY!
