The GASCAP USB-C Tailcap is a 0.60 oz high-impact polymer accessory featuring LINK System technology for modern weapon lights. It provides a paradigm shift in switching by bringing USB-C capabilities to SureFire Scout-style, Modlite, and Cloud Defensive light bodies. The interface ensures near-zero-loss output with a reversible lateral design for flexible cable management and mounting. A specialized cage protects the connected cable to ensure a secure lockup during operation. For activation, it features an onboard full-size latching button for momentary or constant-on use. The unit is compatible with AXON, AXON SL, and ModButton Lite switches and includes a dust cover and clips.
