Unity FAST™ Absolute Riser

The Unity FAST™ Absolute Riser securely elevates block-type red dot optics to a 2.26" optical centerline for absolute co-witness height. It offers a raised M1913 Picatinny platform for direct attachment of optics like EOTech® XPS®, Leupold® LCO®, and other absolute co-witness optics. Pair it with any FAST™ FTC (Flip-to-Center) magnifier mount. Standard with a two cross bolt rail clamp, it's also compatible with the FAST™QD (Quick Detach) Lever.
