Introducing RAILINK® Powered and Data-Enabled ARC Rails for FAST® Helmet Systems


Combat in the Digital Age

Timely, usable data is key to success on the battlefield. With RAILINK, the operator can send and receive real-time information digitally, and its open architecture enables rapid integration of personal protection and situational awareness equipment.



Giving You the Connected Edge

Ops-Core is the leader in total headborne integrated solutions for the Global SOF and Elite LE communities, with a reputation for continually evolving industry standards. RAILINK is no exception. Its innovative design allows electronic systems to mount, power, and communicate with each other, while providing instant feedback to the operator and connecting the operator to others on the mission. The results of ongoing R&D efforts will provide enhanced sensory feedback, threat detection, and the visual representation of shared and received data.

Development Partners

Ops-Core has developed the RAILINK system in conjunction with industry-leading defense technology companies who understand the power of collaboration and work with us to improve and expand the capability of operators.


CORE Survival

A leader in the field of user-defined, field-proven lighting solutions for specialized operations in the Military & LE environments, Core Survival has designed the HEL-STAR Rail Strobe® to be a helmet-rail mounted visible (white) and IR synchronized strobe marker installed on both sides of the helmet—leaving the top of the helmet clear for reduced snag hazards and increased mobility.


Princeton Tec

RAILINK Switch MPLS is a low light/IR directional lighting solution that works with the Gentex RAILINK powered rail system. Weighing in at only 13 grams with an easy-to-operate, glove-friendly switch, it gives the end user a fail-safe lighting solution for all their low light and IR lighting needs.



A trusted source for military and law enforcement personnel worldwide, SureFire continually delivers a critical capability to everyone involved in nighttime operations.
