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.

The FAST™ Offset Optic Base is compatible with all FAST™ mounts for red dots and magnified optics. It is not compatible with FAST™ FTC magnifier mounts.

The FAST™ Offset Optic Base is built from 7075-T6 Aluminum and Type III Hardcoat Anodized coating in Black or FDE*.

The FAST™ Offset Optic Base will always sit on the right side of the FAST™ mount if the mount is facing forward on the M1913 rail. Some FAST™ mounts can be mounted forward or backward on the rail depending on the footprint of the accompanying optic, but in general the FAST™ Offset Optic Base will always sit on the right side of the rifle.

*NOTE: “FDE” is used throughout our catalog to reference a spectrum of colors that include tan, brown, bronze, earth, and everything in between. Due to the chemical process that takes place during Type III Hardcoat, the final finish can vary from part to part (even parts done in the same batch). Therefore, your “FDE” product may vary from other parts from UNITY and other companies, and may vary from the photos shown online.
