The Flux Defense Raider 365 Forward Optic Mount (brand part no. 165-00021) is a chassis-mounted optic bridge built exclusively for the SIG Sauer P365 fire control unit housed in the Flux Raider 365 aluminum chassis. Flux Defense machines the mount from 7075-T6 billet aluminum and cuts a multi-pattern footprint that accepts Trijicon RMR, Shield RMSc, and Holosun K-series optics. Because the mount fixes to the chassis rather than the slide, the dot does not reciprocate during cycling, keeping the aiming point steady shot to shot. Mounting screws, set screws, and a vial of Vibra-Tite thread locker are included. Among red dot mounts, this forward mount favors Raider 365 owners who want a non-reciprocating optic on their PDW build.
