Product Info for Infinite Defense UNITY FAST OPTICS RISER 561584BB

The FAST(TM) Optic Riser securely elevates direct-to-rail mounted red dot optics with a standard lower 1/3 co-witness picatinny mount to a 2.26" optical center line. The FAST(TM) Optic Riser provides an elevated M1913 Picatinny platform for direct attachment of optics, such as EOTechA(R) EXPS, VortexA(R) UH-1 and other lower 1/3 co-witness optics. It can be paired with any FAST(TM) FTC (Flip-to-Center) magnifier mount. It comes standard with a two cross bolt rail clamp, but is compatible with the FAST(TM)QD (Quick Detach) Lever (as of Aug. 2023). If you're running an absolute co-witness height optic, you need the FAST(TM) Absolute Riser. FAST(TM) is a series of optic mounting solutions that provides end users with a quicker sight picture than standard height mounts. FAST(TM) 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(TM) Optic Riser is built from 7075-T6 Aluminum and is Type III Hardcoat Anodized in Black or FDE*.image
