PolarStar FCU (Fire Control Unit) Revision 3
The REV3 FCU follows the classic design of our very first FCU and is considered to be the best fire control units on the market. Equipped with an LCD display and joystick, you can easily navigate through the menus and fine-tune the settings for the utmost control over the system. This FCU is also universally compatible with all PolarStar HPA systems, including dual and single solenoid systems.
This latest REV3 model features updated voltage regulators that greatly improve power efficiency while significantly reducing the overall size. While large in comparison to the Mini FCU, the REV3 FCU is compact enough to fit inside the buffer tube of an M4 along with a small 300mAh Lipo pack.
Another great feature of this FCU is the integral Motor Control Unit (MCU), which allows it to run a box magazine through the MCU port.
- LCD display and joystick for easy and precise adjustments.
- Compact 2.25 x 0.9 inch footprint.
- Integrated engine control unit (MCU).
- Compatible with both Dual and Single Solenoid HPA systems.
