The Jefftron Leviathan V3 Optical monitors the gear position in real time using \u003cstrong\u003etwo optical sensors\u003c\/strong\u003e. The Leviathan unit can be easily programmed via \u003cstrong\u003eBluetooth\u003c\/strong\u003e using a smartphone (iOS or Android).\u003c\/p\u003e\n\u003cp\u003eWith the included foam pad that can be attached to the AK trigger mechanism, the trigger travel can be adjusted to be extremely short, achieving a so-called \"\u003cstrong\u003ehair trigger\u003c\/strong\u003e\".\u003c\/p\u003e\n\u003cp\u003eThe Leviathan V3 Optical unit supports \u003cstrong\u003eRFTS\u003c\/strong\u003e \u003cstrong\u003etechnology\u003c\/strong\u003e (Unique Real Feel Trigger System), where a separate spring mechanism simulates the trigger response of a real AK74. Jefftron worked with a gunsmith specializing in firearms to design the RFTS for a realistic trigger feel.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eTwo-stage trigger\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn addition to the RFTS solution, this product includes a new \"two-stage trigger\" with a realistic pre-travel and a distinct break point.\u003c\/p\u003e\n\u003cp\u003eThe two-stage trigger is an adapter made from 3D-printed plastic and spring steel that replicates the behavior of a two-stage trigger found in real firearms, allowing the user to know exactly when the shot will fire. This improves accuracy and creates a realistic shooting feel.\u003c\/p\u003e\n\u003cp\u003eThe two-stage trigger operates in two clearly defined stages:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIn the first stage, the trigger is pulled smoothly until it hits the wall.\u003c\/li\u003e\n\u003cli\u003eIn the second stage, the trigger weight increases until the wall breaks.\u003c\/li\u003e\n\u003cli\u003eThe \"click\" of the second stage fires the shot.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis solution was designed by gunsmith Tomas Linhart, like other Jefftron RFTS-family solutions. The two-stage trigger differs from the RFTS-V3 spring system included with the Leviathan V3 and offers an improved trigger response. It is also more compatible with different gearbox models than the traditional RFTS spring system. For example, it fits Retro Arms gearboxes directly without modifications.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003eThe Leviathan series offers various expansion options through an output port on the board. (Installing additional accessories requires soldering on the PCB. Leave modifications to a professional.)\u003c\/p\u003e\n\u003cp\u003eThe Leviathan brings a wide range of new features to your AEG and improves existing ones. With this unit, you can control your gun’s fire modes, rate of fire (ROF), pre-cocking, active braking, protect LiPo\/LiFe batteries from over-discharge, and much more.\u003c\/p\u003e\n\u003cp\u003eThe Leviathan unit is installed entirely inside the version 3 gearbox, replacing the traditional trigger switch assembly. The unit comes with pre-installed wiring, including a 40A mini fuse and Deans\/T-connectors.
