The FAST Offset Optic Adapter Plates are designed to mount mini red dot sights onto the FAST Offset Optic Base. This specific plate, the ACRO, utilizes the optic manufacturer's hardware and accepts any mini red dot that fits the ACRO footprint pattern. The adapter can be mounted in three distinct positions on the Offset Optic Base: forward cantilever, centered, or rearward cantilever, allowing for a customized fit.
