Polarstar Trigger Board for M4/V2

Replacement trigger board for the polarstar JACK, F1, or F2.  This board is designed to drop into most V2 style gearboxes and works with PolarStar HPA Units by accepting the dual solenoid leads that are required for the F2 as well as single solenoid units such as the JACK or F1.

This trigger board is compatible with your PolarStar JACK, F1, and F2 systems! For single solenoid systems such as the Jack or F1, place your solenoid connector into the poppet port.  The F2 will use both the poppet and nozzle ports.
