The FAST Offset Optic Adapter Plates place mini red dot sights on the FAST Offset Optic Base. Each plate comes with a specific optic footprint and uses the optic manufacturer's hardware. Each plate footprint will accept any mini red dot with that footprint pattern. Plates can mount in three positions on the Offset Optic Base (forward cantilever, centered, rearward cantilever) for a customized fit.
