Unity Tactical
The Unity Tactical Modular Attached Rail Kit (MARK) 2.0 in Flat Dark Earth is a low-profile helmet-mounted solution designed to integrate electronic hearing protection and communications systems into your headborne setup. Built for operators who need reliable audio gear integration without sacrificing a clean, minimal profile, the MARK 2.0 works with most major helmet platforms and the popular electronic hearing protection options already in your kit—especially 3M Peltor headsets, which mount right out of the box.
What sets the MARK 2.0 apart from traditional headset mounts is its rotating stowage design: rather than awkward pop-in/pop-out mechanics, you simply pull the ear cup away and rotate it backward when you need to stow it. The aggressive wire forms are engineered to maintain an aggressive, consistent seal around the ear cup when the system is engaged—critical for hearing protection performance in the field. The wider ARC backers on this generation offer greater compatibility with non-standard ARC-type rails than the previous model, giving you more flexibility across different helmet types.
Constructed from impact-resistant polymer, the MARK 2.0 is built for austere environments and the kind of abuse that comes with professional use. It ships with all the hardware you need to attach it to Ops-Core ARC rails and Team Wendy EXFIL Gen 2 and 3 systems. If you're running Sordin or MSA-style headsets, you'll need SARA Adapters (sold separately); M-LOK adapter kits are also available separately for MTEK and Hard Head Veterans brand helmets. It's the lowest-profile option on the market for serious headset mounting.

Yes. The MARK 2.0 ships with all hardware needed for 3M Peltor electronic hearing protection and mounts right out of the package.
The MARK 2.0 is compatible with Sordin and MSA-style headsets, but you'll need to purchase SARA Adapters separately, which are sold as an additional accessory.
The MARK 2.0 kit includes all hardware necessary for attachment to Ops-Core ARC rails (and similar rail systems) and Team Wendy EXFIL Gen 2 and 3 helmets. If you're using MTEK or Hard Head Veterans helmets, an M-LOK Adapter Kit is sold separately.
Simply pull the ear cup away from your head and rotate it backward. There's no need to disassemble or pop anything in and out—the rotating design keeps things compact and secure when you're not actively using your headset.
