Unity Tactical MARK 2.0: The Definitive Low-Profile Helmet Mount for Superior Ear Cup Seal & NRR

• The Unity Tactical MARK (Modular Attached Rail Kit) is a field-proven helmet mount that moves your electronic hearing protection from the headband directly to your helmet rails. Built in the USA, this kit eliminates the bulky "pop-in/pop-out" movement of traditional mounts to give you the lowest profile possible in tight spaces. It is the go-to solution for operators who need a reliable seal and a snag-free setup during high-stakes missions.
• Achieve a Tighter Ear Cup Seal for Higher NRR: By removing the traditional "pop-in" mechanism, the MARK allows the ear cups to press more firmly against your head. This design accounts for different head shapes and sizes to ensure your hearing protection reaches its maximum Noise Reduction Rating (NRR). You can pull the cups away and rotate them backward for stowage without losing the tension needed for safety.
• Universal Fit for Most Major Helmet Rail Systems: The Unity Tactical MARK kit comes with all the hardware you need to attach headsets to Ops-Core ARC, Team Wendy EXFIL (2.0 and 3.0), and Busch PROtective rails. It provides a secure mounting point that stays put under 10 in-lbs (1.13 Nm) of torque. This versatility makes it easy to move your preferred headset between different helmet setups as mission requirements change.
• Rugged Performance at Less Than 3.1 Ounces: This kit is made from high-impact polymer to handle the daily abuse of field use without adding significant weight to your head. At under 87.9 grams, the Unity Tactical MARK provides a rock-solid connection that won't cause neck fatigue during long operations. It is built to survive impacts and extreme environments while keeping your communication lines open.
• Full Compatibility with Ops-Core AMP and 3M Peltor Headsets: Specific wire forms allow you to mount the most popular electronic ear protection, including the entire 3M Peltor ComTac series and Ops-Core AMP communication headsets. For those using the Ops-Core AMP, this kit allows you to attach ear cups to the top portion of the rail or use them on helmets like the Crye Precision AirFrame that lack rear rails.

What are some common accessories to add to the Unity Tactical MARK?

System Expansion and Rail Integration for the Unity Tactical MARK 2.0

• Unity MARK M-LOK Adapter: This kit allows you to secure the Unity MARK assembly to M-LOK helmet rails. It includes the necessary hardware to provide a rock-solid connection using standard M-LOK mounting procedures while maintaining the low-profile benefits of the system.

Headset Compatibility and Internal Component Tuning

• Unity MARK for Peltor Wire Form Set: This set provides the specific mounting wires needed for the integration of 3M Peltor-style headsets with the Unity MARK kit. It allows operators to move their Peltor ComTac series ear cups from a headband directly to their helmet rails for a tighter seal and improved NRR.
• Unity SARA Sordin ARC Rail Adapter: This component enables the integration of Sordin-style hearing protection onto ARC-style helmet rails. It bridges the gap between different hardware standards, ensuring that users of Sordin headsets can benefit from a stable, rail-mounted configuration.

Unity Tactical MARK Features & Specifications

The Unity Tactical MARK 2.0 is a field-proven helmet mount designed to provide the lowest profile for communication headsets on the market while maximizing hearing protection safety. By replacing traditional "pop-in/pop-out" mechanisms with a design that allows ear cups to be pulled away and rotated backward for stowage, it maintains a tighter, more consistent seal against the head. This specialized design improves the Noise Reduction Rating (NRR) across various head shapes and sizes, ensuring a secure and snag-free fit during high-stakes operations.

• Full kits come complete with OEM Ops-Core AMP™ Cradle Clamp assemblies and are ready to rapidly attach to headsets out of the box.
• MARK Only kit does not come with the OEM Cradle Clamp assembly and relies on end-users to supply their own Ops-Core AMP™ Cradle Clamps.

Unity Tactical MARK FAQs

What is the Unity Tactical MARK? 

The Unity Tactical MARK is a special kit that lets you attach your ear protection headphones directly to your helmet. It replaces the headband so your gear is less bulky and fits better.

Why is it better than other mounts?

 Most mounts "pop" in and out, which can leave a gap around your ears. The Unity MARK 2 stays tight against your head to block out more dangerous noise.

Will it fit my helmet? 

Yes, the Unity Tactical MARK kit works with most popular helmet rails like Ops-Core ARC, Team Wendy EXFIL, and Busch PROtective. If you have M-LOK rails, you can buy separate Unity MARK adapters to make it fit.

How much does it weigh? 

It is very light and weighs less than 3.1 ounces. This means it won't make your head feel heavy or tired during a long day.

What if my helmet does not have side rails? 

The Unity MARK is perfect for helmets like the Crye Precision AirFrame that do not have rear rails. It lets you attach your ear cups to the top part of the helmet instead.

Unity MARK 2.0 Installation

How to Install the MARK on 3M Peltor Headsets

• Can I use my Peltors with this kit? Yes, this kit is made to work with all 3M Peltor ComTac systems and similar headsets.
• How do I start the installation? First, you must take the headphones off the headband. Be careful because this may include irreversible changes.
• How do I move the parts to the new mount?

1. Turn the stems on your ear cups 90 degrees to line up with the flat spots on the posts.
2. Pop the stems off the posts carefully so you do not break the clamps.
3. Turn the stems 90 degrees again on the wire forms and pull them off the wires.
4. Put everything back together in the reverse order on your new Unity MARK wire forms.

How to Install the MARK on Ops-Core AMP Headsets

• Does this work with AMP headsets? Yes, there is a specific version of the Unity MARK 2.0 just for Ops-Core AMP communication headsets.

• How do I attach the ear cups?

1. Take one side of your current wire form and twist a stem 90 degrees; pull the stem off the wire.
2. Take your new Unity Tactical MARK wire form and twist it 90 degrees to insert it fully into the stem.
3. Make sure the logo on the Cradle Clamp is right-side up and the arrow is pointing up.
4. Push the Cradle Clamp into the hole on the side of the ear cup until it snaps or clicks into place.
