The FAST™ Absolute Riser securely elevates block-type red dot optics with an absolute co-witness height to a 2.26″ optical center line. The FAST™ Absolute Riser provides an elevated M1913 Picatinny platform for direct attachment of optics, such as EOTech^® XPS^®, Leupold^® LCO^® and other absolute co-witness optics. It can be paired with any FAST™ FTC (Flip-to-Center) magnifier mount.

It comes standard with a two cross bolt rail clamp, but is compatible with the FAST™QD (Quick Detach) Lever.

If you’re running a lower 1/3 co-witness height optic, you need the FAST™ Optic Riser.

FAST™ is a series of optic mounting solutions that provides end users with a quicker sight picture than standard height mounts. FAST™ mounts create a 2.26” optical centerline from the rail, which allows for more rapid visual processing of the battlefield by ensuring an ergonomically correct heads-up posture. Further, they provide faster and easier dot/reticle acquisition while wearing night vision goggles, protective masks, plate carriers and other gear.

The FAST™ Absolute Riser is built from 7075-T6 Aluminum and is Type III Hardcoat Anodized in Black or FDE*.
