The Unity Tactical SARA (Sordin Arc Rail Adapter) allows for seamless, direct integration of Sordin-based communication headsets onto tactical helmet rail systems. By removing the factory headband, it completely eliminates the interior hot spots, headaches, and physical discomfort traditionally caused by clamping steel bands inside a tight helmet shell. The system utilizes the specialized spring tension of a host MARK™ or Peltor™ wire mount to pull the earcups tight against the head for a reliable sound seal. CNC-machined from robust 6061-T6 aluminum bar stock, these adapters deliver high structural durability while maintaining an ultra-lightweight profile on the helmet. Finished in a clean Type III hardcoat anodized black, the kit includes ESS replacement studs to easily convert both over-the-head and behind-the-head ear protection variants.
