Jefftron – Intelligent electronics for your airsoft rifle
If you want maximum performance from your AEG, Jefftron is the natural next step in your upgrade. Jefftron specialises in advanced MOSFET systems and ETUs that not only protect your rifle's electrical system, but also give you functions standard rifles can only dream of. We carry everything from discreet micro MOSFETs to the Leviathan units controlled directly from your smartphone.
Leviathan: the ultimate control
Jefftron's flagship, the Leviathan, is one of the most advanced ETUs on the market. By replacing your mechanical trigger contacts with a Leviathan, you open up a whole new world:
Smartphone control: Set rate of fire, trigger response and fire modes (e.g. burst or binary trigger) directly via Bluetooth in Jefftron's app.
Battery and rifle protection: The unit monitors your battery and stops the rifle before the voltage gets too low, while also protecting against short circuits.
Precise cycle control: Makes sure your piston always stops in the right position, which gives a more consistent muzzle velocity and less wear on your gears.
MOSFETs for every need
Not everyone needs a full computer in their rifle. That is why Jefftron also offers simpler solutions that make a huge difference:
Micro MOSFETs: Perfect for small gearboxes or compact setups. They route the current around your trigger contacts, so you avoid the classic burnt contacts when using powerful LiPo batteries.
Processor units: Get functions such as burst and adjustable rate of fire without replacing the whole trigger system.
Active brake: Several Jefftron models have built-in active braking, which stops the motor instantly so you avoid double shots in semi-auto.
Upgrading and installation
Jefftron is designed to fit most standard gearboxes (V2, V3 and others), which makes it ideal for both G&G and ICS rifles. To get the most out of your Jefftron unit, we recommend pairing it with a quality battery from GP Batteries and making sure your wiring is routed correctly.
Looking after your electronics
Electronics and moisture are rarely good friends. Although Jefftron units are robust, we always recommend keeping your rifle dry. If you need to clean contacts or connectors, a little electronics cleaner or Brunox can help keep the connection clean.
