Unity Tactical Modular Attached Rail Kit (Mark) 2.0 Helmet Mount Only Black

The Unity Tactical Modular Attached Rail Kit (MARK) 2.0 is a low-profile helmet-mounted solution designed to secure your electronic hearing protection and communications headsets to tactical helmets without the bulk or complexity of older mounting systems. This helmet mount only version works exclusively with Ops-Core AMP headsets and requires you to supply your own OEM Ops-Core AMP Cradle Clamps — making it ideal for operators who already have compatible clamps in hand or want to integrate multiple headset configurations across their kit.

Built from impact-resistant polymer, the MARK 2.0 delivers rugged reliability in austere field conditions. The wider ARC backers provide broader compatibility with non-standard ARC-type rails compared to the original model, while the low-profile design keeps your helmet setup streamlined and balanced. Instead of the traditional pop-in/pop-out mechanism, the MARK 2.0 simply rotates backward and away from your ears for quick stowage — no fidgeting with pins or clips. The aggressive wire forms maintain an aggressive seal on your ear cups when the mount is engaged, so your hearing protection stays where it belongs whether you're breaching, moving between positions, or maintaining security in rough terrain.

Compatible with Ops-Core ARC rails and Team Wendy EXFIL Gen 2 and 3 rails with included hardware. Note: the AMP-specific wire forms differ from legacy MARK 2.0 models and are not interchangeable with older Cradle Clamps due to length and crimp direction. If your helmet lacks a rear rail, the MARK 2.0 AMP still mounts at the 12 o'clock position for broader helmet acceptance. Black finish.

Frequently Asked Questions

Is the MARK 2.0 AMP helmet mount compatible with my Ops-Core helmet?

The MARK 2.0 AMP mounts to helmets with Ops-Core ARC rails or Team Wendy EXFIL Gen 2 and 3 rails, and it can attach at the 12 o'clock position even on helmets without rear rails. Confirm your helmet model before ordering. An M-LOK Adapter Kit (sold separately) extends compatibility to MTEK and Hard Head Veterans brand helmets.

What's the difference between the MARK 2.0 helmet mount only and a full kit?

The helmet mount only version does not include OEM Ops-Core AMP Cradle Clamp assemblies — you must supply your own compatible clamps. Full kits include the Cradle Clamps and are ready to attach to headsets out of the box. Choose the mount-only option if you already own compatible clamps or plan to source them separately.

Can I use old MARK 2.0 wire forms with the AMP version?

No. The AMP-specific wire forms are different in length and crimp direction and are not compatible with legacy MARK 2.0 Cradle Clamps. Use only AMP-compatible wire forms and Cradle Clamps with this mount.

How does the stowage mechanism work on the MARK 2.0?

Instead of a traditional pop-in/pop-out clip, the MARK 2.0 simply rotates backward and away from your ears for quick stowage. The aggressive wire forms keep your ear cups sealed when the mount is engaged and allow you to break the connection without tools or fumbling.
