Modular Attached Rail Kit (Mark) 2.0 W/Ops Core Fde
The Unity Tactical Modular Attached Rail Kit (MARK) 2.0 with Ops Core FDE is a helmet-mounted solution designed to integrate electronic hearing protection and communications systems into your headborne setup while improving ear protection seal. Built for tactical and professional users who need reliable, low-profile headset mounting, the MARK 2.0 combines compatibility with top helmet platforms, aggressive wire forms for secure fit, and a stowage design that doesn't rely on traditional pop-in/pop-out mechanisms.
This FDE variant comes configured to work with the Ops-Core AMP headset and includes OEM Ops-Core AMP Cradle Clamp assemblies—meaning your kit is ready to attach to compatible headsets right out of the box. Unlike traditional helmet mounts that require rear-rail attachment, the MARK 2.0 AMP mounts at the 12 o'clock position, which opens up compatibility with a broader range of helmet types. If your helmet lacks a rear rail, you can still deploy this system. The impact-resistant polymer construction is engineered to perform in austere environments where durability and consistency matter.
To stow your headset, simply rotate the ear cups away from your ears and back—no fiddly mechanisms to break or lose. The wider ARC backers offer improved compatibility with non-standard ARC-type rails compared to earlier generations. Note that the AMP version's wire forms differ from legacy MARK 2.0 designs and are not interchangeable with older Cradle Clamps due to length and crimp direction differences.
For users running Ops-Core ARC, Team Wendy EXFIL Gen 2, or Team Wendy EXFIL Gen 3 rails, the hardware is included. M-LOK-equipped helmets from MTEK and Hard Head Veterans require a separate M-LOK Adapter Kit for compatibility.

Frequently Asked Questions
Is the MARK 2.0 AMP compatible with my helmet?
The MARK 2.0 AMP mounts at the 12 o'clock position and works on helmets equipped with Ops-Core ARC, Team Wendy EXFIL Gen 2, or Team Wendy EXFIL Gen 3 rails. Importantly, it also functions on helmets without rear rails. If your helmet uses M-LOK slots (MTEK or Hard Head Veterans), you'll need to purchase a separate M-LOK Adapter Kit.
Does this kit come ready to use out of the box?
Yes. This full kit includes OEM Ops-Core AMP Cradle Clamp assemblies and all necessary hardware for attachment, so you can mount it to your Ops-Core AMP headset immediately upon receipt.
Can I use legacy MARK 2.0 wire forms with the AMP version?
No. The AMP variant uses wire forms specifically designed for the Ops-Core AMP Cradle Clamps. Legacy MARK 2.0 wire forms are incompatible due to differences in length and crimp direction.
How do I stow the headset when not in use?
Rather than using a traditional pop-in/pop-out mechanism, you simply rotate the ear cups away from your ears and fold the assembly back for stowage. The aggressive wire forms maintain a strong seal when the headset is engaged and allow smooth rotation for storage.
