The FAST MRDS mount, in conjunction with the Optic Adapter Plates in the FAST Modular Accessory Suite, brings compatible micro red dot sights to the established FAST height of 2.26″ to optical centerline. This includes micro red dot sights with any of the following footprints: RMR, DeltaPoint Pro, ACRO, 509T, RMSc and Holosun K. It comes standard with a two cross bolt rail clamp or can be retrofitted with the FASTQD (Quick Detach) Lever. With exception to the Leupold DeltaPoint Pro, it is also compatible for use with the line of FAST FTC magnifier mounts.
