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*.

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.
