The FAST™ 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™ Optic Riser provides an elevated M1913 Picatinny platform for direct attachment of optics, such as EOTech® EXPS, Vortex® UH-1 and other lower 1/3 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 (as of Aug. 2023).
If you’re running an absolute co-witness height optic, you need the FAST™ Absolute 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™ Optic Riser is built from 7075-T6 Aluminum and is Type III Hardcoat Anodized in Black or FDE.
