GATE Completed EON CNC Gearbox and TITAN II Bluetooth® EXPERT V2 (1.8 J) - Rear Wiring

Complete CNC Gearbox EON V2 and TITAN II Bluetooth® EXPERT V2 by GATE

Are you looking for the ultimate upgrade for M4 / AR15 AEG rifles without the need for your own assembly and tuning? Do you want maximum reliability, quiet operation, and top-tier electronics in one complete unit? Then the complete CNC EON V2 gearbox with the TITAN II Bluetooth® EXPERT unit is exactly what you are looking for. GATE has prepared a straightforward solution for anyone who wants to upgrade their AR15-based AEG rifle effortlessly. This fully assembled CNC EON V2 gearbox features premium internal components and the TITAN II EXPERT processor unit with Bluetooth® connectivity. Everything has been precisely assembled and tuned by GATE technicians.
The shell is milled from aircraft-grade aluminum on high-precision CNC machines and features inspection windows for checking and tuning AoE (angle of engagement), pre-cocking, or motor height. The gearbox also allows quick spring change (QSC). In addition, it is compatible with the QSC system Specna Arms ESA-2. Installation is possible in most standard M4 / AR15 receivers on the market, including VFC rifles with dual selectors. The entire system is designed to deliver a consistent output of 1.8 J (approx. 134 m/s) without fluctuations, with quiet operation and extreme reliability. The upgrade is straightforward—simply install the gearbox into the receiver and connect the motor. This makes it an ideal choice not only for beginners, but also for advanced players who want a high-quality solution without the need for tuning. Of course, proper alignment of the gearbox to the hop-up chamber must be ensured.
TITAN II Bluetooth® is the most advanced processor unit from GATE, designed for V2 gearboxes, not only in AEG but also in HPA builds. It offers not only the most precise trigger sensor in the world, but also a completely new gear detection sensor that detects every gear tooth and rotation direction. The result is an unmatched level of control over the firing cycle. Thanks to Bluetooth 5.2, TITAN II can be connected directly to the GATE Control Station application (download it here), where you can configure all unit functions, update firmware, monitor shot statistics, battery voltage, and more. It also supports connectivity with smartwatches and the GATE STATUS system for complete real-time overview of the rifle, battery capacity, and remaining BBs directly in combat.

Warning

• The QSC spring guide is sealed; if the seal is broken, warranty claims for gearbox and internal damage cannot be accepted, as the installation of a stronger spring cannot be ruled out.
• Actual output may vary slightly depending on BB weight, inner barrel length, and other factors.
• For proper function, we recommend using a quality motor and a correctly matched inner barrel according to cylinder volume (approx. 250–430 mm).
• The GATE Control Station application can be downloaded from the official GATE website.
