Available now! The LINK™ USB-C System from Unity Tactical. This system includes GASCAP™ – a LINK™ USB-C Tailcap for SureFire® Scout®-style weapon lights – and the addition of LINK™ USB-C capability to our AXON™, AXON™ SL and ModButton™ Lite lines of switches.

The LINK™ System marks a paradigm shift for switching technology, bringing USB-C capabilities to weapon mounted lights and switches that will expand future capabilities. The robust performance of the LINK™ System interface provides near-zero-loss output and dependable repeatable activation. The lateral and reversible interface on the GASCAP™ provides a variety of mounting and cable management options, while the GASCAP™ cage protects the cable and ensures a solid lockup. GASCAP™ features an onboard full-size latching button for momentary or constant activation of your device.

Made of high-impact polymer, GASCAP™ weighs nearly one ounce less than other available tailcaps. Its superior strength-to-weight ration means it’s durable in even the most severe environments. The LINK™ System will initially be offered with GASCAP™ and within UNITY’s AXON™, AXON™ SL and ModButton™ Lite switch portfolios, with future switching innovations and product expansions to come.

GASCAP™ will initially be available for SureFire® Scout-style weapon lights in Black or FDE. GASCAP™ along with LINK™ USB-C compatible AXON™, AXON™ SL, and ModButton™ Lite switches will be available for purchase in October.

    Solid option to replace the SF DS switches. The retaining band for the connector could be improved, but it works. Looking forward to seeing where the development of this switch goes.

    Been waiting for something to replace the trash that is the DS00.

    Very ingenious product, these are going to be my new ’go to’ for weaponlight setups. Highly suggest trying one out. Rear button is very nicely tensioned, and the USB-C connection is also very intuitive.

    Great button and great design. Wish the cover pieces were a bit stronger than they feel.
