Overview
The RAILINK-Enabled FAST SF pairs the Ops-Core FAST SF helmet with the RAILINK Power and Data ARC Rail system factory-installed. Instead of running individual CR123 or AA cells in every supported device, the helmet can route power and data through the rails to compatible accessories when configured with a Battery Pack+ controller.
The system auto-selects voltage: 3V or 9V for NVGs (PVS-31A, BNVD-1531, GPNVG-18, Kestrel), and 13V for accessory nodes. Compatible accessories at launch include the Princeton Tec Switch MPLS in a RAILINK variant, the SureFire HL2-A white/IR light, and the CORE Survival HEL-STAR Rail Strobe. Gentex has also signed development partnerships with MOHOC, AMAD, NanoAi, and seven other licensees, so the accessory ecosystem will keep expanding.
RAILINK adds approximately 8 oz (226 g) of rails and hotshoe weight versus the bare FAST SF, before separately selected Battery Pack+ and accessories. Lead times are 6 weeks for single orders and 8-12 weeks for multiple units. This is the right buy if you are kitting out a new high-end build and want to consolidate batteries and cables, not the right buy if you already own a working FAST SF and a stack of accessories on standard ARC rails.
