The Truglo Tru-Tec pistol optic adapter plate lets you mount a red dot with a Truglo, Vortex Viper/Venom, or Docter footprint onto a pistol slide that is cut for the Trijicon RMR pattern. The plate sits between your slide and optic to bridge the two mounting patterns. Features: Adapts a Truglo / Vortex Viper / Docter-footprint red dot to an RMR-cut slide Adapter plate only - optic and slide sold separately Steel construction Mounting hardware included Before ordering, confirm your slide is cut for the RMR footprint and that your optic uses the Truglo / Vortex / Docter footprint. The C plate is easy to confuse with the TG8952B plate, which runs the conversion in the opposite direction.
