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

GATE delivers the ultimate solution for anyone looking to upgrade their AR15-style AEG rifle effortlessly. This fully assembled CNC EON V2 gearbox features premium components and the TITAN II EXPERT processor unit with Bluetooth® connectivity, all precisely tuned by GATE technicians.
The gearbox shell is milled on high-precision CNC machines, and features inspection windows for tuning and checking the AOE (angle of engagement), pre-cocking, or motor engagement. It also supports quick spring change (QSC). Additionally, it's compatible with Specna Arms ESA-2 system. It fits most standard M4 / AR15 bodies, including VFC bodies with dual selectors.
This setup is engineered to provide a consistent 1.9 J output (approx. 140 m/s) with smooth operation and maximum reliability. Installation is straightforward – just insert it into the rifle body and connect the motor. It's an ideal solution not only for beginners, but also for advanced players who want a high-performance system without the hassle of tuning. Of course, make sure the gearbox-to-hop-up alignment is correct.
TITAN II Bluetooth® is GATE's most advanced processor unit, designed for V2 gearboxes in both AEG and HPA setups. It features the world’s most precise trigger sensor along with a brand new gear sensor that detects every tooth and rotation direction. This results in unmatched control over the firing cycle. Through Bluetooth 5.2, the TITAN II connects directly to the GATE Control Station app (download here), allowing full configuration, firmware updates, shot statistics, battery monitoring and more. It also supports smartwatch integration and the GATE STATUS system for a complete overview of your weapon, battery level and magazine count – right in the field.
