UNITY FAST ABSOLUTE RISER FDE

Description

The Unity Tactical FAST Absolute Riser is built for shooters who run red dot optics with absolute co-witness height and need to adapt them to a 2.26-inch optical centerline. That specific height is not arbitrary: when you are shooting with a helmet, electronic ear protection, night vision goggles, or a protective mask, a standard-height mount pushes your head down into an awkward, chin-to-chest position just to find the reticle. Raising the optic to 2.26 inches lets you keep a more upright, heads-up posture, which cuts the time between acquiring a sight picture and processing what you are looking at.

The riser is optimized for block-style absolute co-witness optics such as the EOTech XPS and Leupold LCO — optics that sit directly on the rail and present their reticle at iron-sight level on a standard receiver. By adding the FAST Absolute Riser underneath, you preserve the co-witness geometry those optics were designed around while moving the whole system up to a height that works with full kit. The 3.5-inch Picatinny rail section on top accommodates optics of varying footprints without restricting your choices to a single model.

Construction is 7075-T6 aluminum with a Type III hardcoat anodized finish in Flat Dark Earth. The rail grabber clamp system is compatible with the FAST QD Lever and the ADM-made FAST QD Lever, so if you are already running Unity’s quick-detach ecosystem, this riser integrates without additional hardware. At 2.8 ounces, it adds negligible weight to the host rifle.
