Ops-Core RAC Headset (Rail Attached Communications)

Helmet rail-mounted comms headsetCommunications

The RAC Headset mounts to the rear of the Ops-Core ARC rails on FAST and Sentry helmets, leaving the top of the rails free for lights and cameras. It combines hearing protection with 3D Hearing Technology hear-through audio, a noise-cancelling boom microphone and a quick-release downlead, and keeps working for communications if its batteries run out.

    Low Profile Stowage

    When not in use the earcups rotate to the rear of the helmet for a very low profile, and a quick-release downlead lets the user remove the helmet without excess cables.
