The Mark headset helmet mount is engineered to minimize the overall profile of mounted communication headsets while enhancing the ear protection seal. It is the most compact headset helmet mount available. Unlike traditional pop-in/pop-out mechanisms, the Mark design allows the ear cups to be pulled away from the ears and rotated backward for storage. This design choice accommodates the diversity in head shapes and sizes, eliminating the need for a pop-in/pop-out mechanism and providing a more secure seal for the ear cups, thereby achieving a higher noise reduction rating (NRR). The Mark is compatible with most major helmet rail systems, facilitating the attachment of various popular electronic hearing protection devices. It includes all necessary hardware for Ops-Core ARC rails (and similar systems), Team Wendy Exfil rail systems and Busch protective rail systems. M-Lok adapters are available separately. Models are not interchangeable. The Mark specifically enables the use of Ops-Core AMP headsets for users who prefer to attach their ear cups to the upper portion of the rail or for helmets lacking rear rails, such as the Crye Precision AirFrame.
