Mounting absolute co-witness sights directly to standard height receiver rails often creates severe ergonomic constraints, forcing shooters into a collapsed neck position that hampers mobility and obscures sight pictures when wearing night vision goggles or modern protective masks. The Unity Tactical FAST™ Absolute Riser resolves this geometric limitation by creating an established 2.26″ optical centerline when paired with absolute co-witness rail-mounted sights, such as the EOTech® XPS Series. By elevating optics to this baseline, shooters achieve a natural "heads-up" posture that speeds up reticle acquisition, maintains peripheral awareness, and facilitates unhindered passive aiming through helmet-mounted night vision optics. Key Features Tailored for Absolute Co-Witness Optics: Specially dimensioned to bring absolute co-witness sights like the EOTech® XPS series up to a 2.26″ optical centerline. Enhanced Heads-Up Ergonomics: Elevates line of sight to reduce neck strain and simplify target acquisition while wearing comms gear, gas masks, or NVGs. 7075-T6 Aerospace Aluminum: CNC-machined from lightweight, heavy-duty 7075-T6 aluminum to endure extreme dynamic impacts. Mil-Spec Hardcoat Anodized: Features a Type III hardcoat anodized finish for maximum resistance against abrasion and corrosion. Modular Ecosystem Integration: Ships standard with a robust two cross-bolt rail clamp, supports the optional FAST™ QD Lever, and pairs cleanly with any FAST™ FTC magnifier mount.
