The Unity Tactical Modular Attached Rail Kit (MARK) 2.0 is a helmet-mounted headset adapter designed to secure communications and electronic hearing protection to tactical headborne systems with a rock-solid, consistent seal. If you're running helmet-integrated comms or powered ear pro on ops, this rail kit bridges the gap between your headset hardware and your helmet's attachment points—eliminating shift and rattle that compromise both function and comfort during extended wear.
The MARK 2.0 stands out for its ultra-low profile and retention method: instead of fussy pop-in/pop-out mechanisms, you simply rotate the ear cups backward and away from your head for stowage or adjustment. The reinforced wire forms clamp the ear cups firmly in place when deployed, ensuring your hearing protection stays sealed and positioned correctly shot after shot or mission after mission. Built from impact-resistant polymer, it's engineered to survive rough handling and austere field conditions without degradation.
Compatibility is broad out of the box: the kit ships with all hardware needed for Ops-Core ARC (and ARC-compatible) rails as well as Team Wendy EXFIL Gen 2 and Gen 3 systems, and works directly with 3M Peltor electronic headsets. The wider ARC backers in this 2.0 revision accommodate non-standard ARC-type rails better than the original design. If you're running Sordin or MSA-pattern headsets, the SARA Adapters are available separately. MTEK and Hard Head Veterans helmet users will need the M-LOK Adapter Kit (sold separately) to integrate with their platform.
Whether you're training at an indoor range, running force-on-force drills, or gearing up for duty, the MARK 2.0 keeps your comms and ear pro exactly where they need to be—stable, sealed, and instantly accessible.

Yes. The kit includes all mounting hardware needed for Ops-Core ARC rails and Team Wendy EXFIL Gen 2 and Gen 3 helmets. If you're running a different helmet system, check the compatibility details above or contact us to confirm your specific platform.
Yes. The MARK 2.0 is designed to work with 3M Peltor electronic hearing protection right out of the package with no additional adapters required.
The MARK 2.0 is compatible with Sordin and MSA-pattern headsets, but you will need to purchase the SARA Adapters separately to attach them.
Unlike older designs, the MARK 2.0 doesn't rely on a pop-in/pop-out mechanism. Simply pull the ear cups away from your head and rotate them backward for stowage or quick repositioning. This design is faster and more reliable than traditional brackets.
