Unity FAST Absolute Riser

FAST™ is a series of optic mounts and platforms that provide end users with a quicker sight picture than standard height mounts. A 2.26” optical centerline height provides faster/easier reticle acquisition while wearing electronic ear pro/communications headsets, night vision goggles and protective masks, and allows for more rapid visual processing of the battlefield by promoting a heads-up posture. A heads-up posture also helps users maintain a neutral spine position which is more comfortable while wearing helmets, plate carriers and other heavy gear.

FAST™ Absolute Riser securely elevates block-type red dot optics with an absolute co-witness height to a 2.26″ optical center line.  FAST™ Absolute Riser provides an elevated M1913 Picatinny platform for direct attachment of optics, such as EOTech^® XPS^®, Leupold^® LCO^® and other absolute co-witness optics.

If you’re running a lower 1/3 co-witness height optic, you need the FAST™ Optic Riser.

NOTE: “FDE” is used throughout UNITY catalog to reference a spectrum of colors that include tan, brown, bronze, earth, and everything in between. Due to the chemical process that takes place during Type III Hardcoat, the final finish can vary from part to part (even parts done in the same batch). Therefore, your “FDE” product may vary from other parts from UNITY and other companies, and may vary from the photos shown online.
