Description
Product Details

The Leviathan V3 Optical Control Unit (Front Wires) from JeffTron is not just a simple MOSFET: it's a complete onboard computer that takes your replica into the future. Designed for V3 gearboxes (AK, G36, AUG, MP5K), it entirely replaces the original mechanical contacts with a digital optical system controllable via Bluetooth.

Why choose Leviathan V3 Optical?

1. Total Control via Smartphone:
Forget complicated programming with triggers. Thanks to the integrated Bluetooth module, you can connect the replica to the JeffTron App (iOS, Android and Smartwatch) to view real-time statistics and modify every single firing parameter.

2. RFTS (Real Feel Trigger System):
Unique in its kind, this control unit integrates the RFTS system: a special spring that simulates the resistance of a real firearm trigger and provides a mechanical "reset" after each shot. This tactile feedback, combined with the ability to insert foam shims (included), allows you to create a millimeter Hair Trigger.

3. Indestructible Optical Sensors:
No more copper contacts that carbonize. The Leviathan uses optical sensors to detect the position of the sector gear and fire selector, guaranteeing eternal durability and absolute cycle precision.

Advanced Functions Table

Function	Description
Firing Mode	9 modes configurable independently for each selector position (e.g. Safe, Semi, Binary, Burst, Auto, etc.).
Pre-Cocking	Keeps the spring pre-compressed for an instant trigger response in single (SEMI).
Active Brake	Active motor brake with adjustable power. Stops the piston always in the same position and eliminates double shots.
Virtual Magazine	Simulates real capacity magazines. Blocks the rifle when you run out of virtual rounds and requires a reload.
ROF Control	Reduce the rate of fire electronically to make the burst more realistic or save BBs.
Brushless Ready	Full compatibility with Brushless motors (e.g. Warhead) without overheating.
