Modular Attached Rail Kit (Mark) 2.0 W/Ops Core Black

The Unity Tactical Modular Attached Rail Kit (MARK) 2.0 with Ops-Core Black is a low-profile helmet-mounted solution purpose-built for operators running electronic hearing protection and comms headsets. If you're integrating an Ops-Core AMP headset into a tactical helmet setup, this kit bridges the gap between your headgear and comms without the bulk of traditional mounting solutions. It comes ready to install with OEM Ops-Core AMP Cradle Clamp assemblies included, so you can attach it straight to your headset and helmet out of the box.

The MARK 2.0 AMP version mounts at the 12 o'clock position on your helmet's rail system, and that centered placement opens up compatibility with a wider range of helmet models. Unlike the original MARK design, the AMP variant works even on helmets without rear rails—a meaningful advantage if you're running non-standard configurations or upgrading equipment piecemeal. The stowage method ditches the traditional pop-in mechanism; instead, you simply pull the ear cups away and rotate them backward when you need them out of the way. This design keeps your comms and hearing protection integrated with your kit rather than dangling separately.

Built from impact-resistant polymer, the MARK 2.0 is engineered for rough field use and delivers an aggressive wire form that locks the ear cups firmly in position. The wider ARC backers improve fitment over previous generations, reducing slop on helmet rails and maintaining a consistent seal for hearing protection. Whether you're conducting training runs, tactical operations, or field work that demands reliable audio comms, this is the kind of gear that stays out of your way and works when it matters.

Frequently Asked Questions

What helmets will this work with?

The MARK 2.0 AMP mounts to Ops-Core ARC-type rails and Team Wendy EXFIL Gen 2 and 3 systems. It also works on helmets without rear rails, attaching at the 12 o'clock position. If you run MTEK or Hard Head Veterans helmets with M-LOK rails, an M-LOK Adapter Kit is available separately.

Does this come ready to install?

Yes. This full kit includes OEM Ops-Core AMP Cradle Clamp assemblies and all hardware needed to attach directly to your headset and helmet. You can set it up and deploy right away. (A MARK Only variant is also available separately if you already own Ops-Core AMP Cradle Clamps.)

How do I stow this when I'm not using the comms?

Pull the ear cups away from your head and rotate them backward. The MARK 2.0 AMP uses this rotate-back design instead of a traditional pop-in/pop-out mechanism, keeping your headset integrated with your helmet and ready to swing forward again.

Are the wire forms the same as the older MARK 2.0?

No. The AMP version uses different wire forms specifically engineered for the Ops-Core AMP Cradle Clamp design. Legacy MARK 2.0 wire forms are not compatible with AMP Cradle Clamps due to differences in length and crimp direction.
