FAST OFFSET OPTIC BASE

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.
