The Unity Tactical MARK 2.0 M-LOK Adapter Kit expands the multi-rail versatility of your headborne communications gear by allowing users to migrate onto standard M-LOK slots. While a factory-packaged MARK 2.0 hub assembly ships standard with hardware tailored for Ops-Core ARC and Team Wendy EXFIL rails, this dedicated hardware kit swaps out those legacy components. It enables direct, secure anchoring onto M-LOK geometry helmet frames—such as the MTEK FLUX or Hard Head Veterans lines—without relying on bulky, unstable picatinny transition brackets. Manufactured with close-tolerance thread pitches, the high-strength steel mounting screws and T-nuts pull the main polymer MARK arms tight and completely flush along the sides of the helmet shell. This eliminates wobble under field impact, ensures a continuous, high-pressure ear cushion seal to optimize hearing protection, and clears top channels for secondary lights or cameras.
