FAST™ Offset Optic Base – Modular Secondary Optic Mount

The FAST™ Offset Optic Base is part of the FAST™ Modular Accessories, designed to provide users with the flexibility to mount secondary or backup optics and BUIS (Back-Up Iron Sights) to compatible FAST™ mounts that are already hosting primary-use optics. This base attaches directly to the FAST™ mount, creating a solid platform for attaching FAST™ Optic Adapter Plates.

When paired with a FAST™ Optic Adapter Plate, the FAST™ Offset Optic Base allows for the secure attachment of micro red dot sights, positioning them at a 36-degree offset from the primary optic mount. This provides users with quick access to secondary optics without interfering with the primary optic. The mechanical centerline of the micro red dot sight sits at 2.05” above the rail, offering an ergonomically correct heads-up posture for rapid transitions and better battlefield visibility.

Key Features:

• Modular Design: Pairs with any FAST™ Optic Adapter Plate to mount micro red dot sights.
• Optimal Positioning: Places micro red dot sights at a 36-degree offset from the main optic for rapid acquisition of secondary sight pictures.
• Compatibility: Works with all FAST™ mounts for both red dots and magnified optics; not compatible with FAST™ FTC magnifier mounts.
• Material: Made from 7075-T6 aluminum for exceptional strength and durability.
• Coating: Finished with a Type III Hardcoat Anodized coating for superior wear and corrosion resistance.
• Weight: Weighs less than 1.0 oz (29.0 g), adding minimal weight to your setup.

Compatibility:

• Works with all FAST™ Optic Adapter Plates in the FAST™ Modular Accessory Suite.
• Compatible with all FAST™ mounts for red dots and magnified optics, but not compatible with FAST™ FTC magnifier mounts.
• The FAST™ Offset Optic Base is always mounted on the right side of the FAST™ mount when facing forward on the M1913 rail.
