Thyrm VariArc Helmet Light Mount

The VariArc® is the tactical helmet light mount built for operators who demand reliability under any conditions. Conceived by Josh Jackson (SWAT-LEO) at LMS Defense with direct input from SWAT commanders and special operations soldiers, the VariArc locks firmly into the forward index position for critical tasks — then rotates through 8 additional positions with a firm twist for umbrella lighting, admin tasks, and IR signaling on demand.

Available for Ops-Core® (Dovetail), Team Wendy®, and M-LOK® side mounts. The Picatinny rail ensures compatibility with virtually any visible or IR light on the market.
