FAST™ Modular Accessories afford several options to attach secondary/back-up optics and BUIS to compatible FAST™ mounts hosting primary-use optics. The FAST™ Offset Optic Base attaches directly to the FAST™ mount, providing a platform for attaching FAST™ Optic Adapter Plates.
Together with a FAST™ Optic Adapter Plate, which is required for the FAST™ Offset Optic Base to function, it provides a base for attaching any number of micro red dot sights directly to the compatible FAST™ optic mount. The Offset Optic Base places micro red dot sights at a 36 degree offset from the centerline of the optic mount. When used with an Optic Adapter Plate, the micro red dot will have a mechanical centerline of 2.05” above the rail.
