The Unity Tactical SARA Sordin Arc Rail Adapter Kit allows users to directly attach MSA Sordin-based communication headsets to tactical helmet rail systems. By converting your ear protection into a rail-mounted configuration, this kit eliminates the painful pressure points and headaches traditionally caused by wearing a rigid headset headband underneath a tight combat helmet. Crafted in the USA from ultra-rugged 6061-T6 aluminum, these components feature a Type III hardcoat anodized finish to ensure they withstand harsh operational environments without failing. The kit specifically includes custom ESS replacement studs, making it universally compatible with both Over-The-Head (OTH) and Behind-The-Head (BTH) Sordin headset configurations. When paired with Unity MARK rail adapters, the system leverages continuous spring tension to maintain a perfect, dependable acoustic seal around your ears.
