The PolarStar REV3 FCU is equipped with an LCD screen and joystick, allowing you to easily navigate menus and fine-tune settings for perfect adjustment of your HPA gun. This FCU is compatible with all PolarStar HPA systems, including both dual-solenoid and single-solenoid configurations.
Compared to previous versions, the REV3 model features updated voltage regulators that significantly improve energy efficiency and greatly reduce the physical size of the FCU. While the REV3 FCU is larger than the PolarStar Mini FCU, it is still compact enough to fit inside an M4 buffer tube along with a small 300 mAh LiPo battery pack.
Another great feature of this FCU is its integrated Motor Control Unit (MCU), which enables the use of box magazines through the MCU port.
