3M PELTOR ComTac ARC Adapter Helmet Mounts
3M PELTOR ComTac ARC Adapters mount ComTac headsets directly to Ops-Core ACH/ARC helmet rails, replacing the headband for a more comfortable and low-profile fit. The flip-up design allows quick stow or removal, and the built-in mic interface on one adapter supports a clean, helmet-integrated comms setup.
3M™ PELTOR™ ComTac™ ARC Adapter Helmet Mounts are a mission-grade rail mounting solution that lets you attach 3M™ PELTOR™ ComTac™ hearing protection directly to Ops-Core® and other helmets using the ACH/ARC rail standard. Built for professionals, these adapters deliver a stable, low-profile, helmet-integrated setup without the bulk or pressure points of a traditional headband.
Installation is straightforward and secure: left and right mounts lock into the helmet rails, keeping the earcups perfectly aligned even during aggressive movement, crawling, or vehicle work. By replacing the headset headband, ARC adapters improve long-duration comfort and compatibility with layered gear such as balaclavas, hoods, eye protection, and comms routing.
The flip-up mechanism adds real operational flexibility. You can swing the earcups away in seconds when you need more open hearing or quickly remove the headset entirely without fighting straps or re-routing your helmet setup. This makes them ideal for dynamic environments like range training, instruction, observation, or rapid transitions in and out of vehicles.
One of the adapters includes a dedicated microphone interface point, allowing a 3M™ PELTOR™ boom mic to mount cleanly as part of the helmet system. The result is a compact, snag-free comms platform where the mic stays exactly where it should, even under hard use.
Compatible with ComTac™ headsets and Ops-Core® ACH/ARC rails, these adapters are a key upgrade for users who demand reliability, speed, and seamless integration of hearing protection with a helmet-borne loadout.
