The Unity Tactical FST-RAB Fast™ Absolute Riser is a precision-engineered optic mount made from durable 7075-T6 aluminum with Type III hardcoat anodizing. Designed for rapid reticle acquisition at a 2.26” optical centerline height, it enhances user comfort and situational awareness when wearing tactical gear. Compatible with all direct-to-rail optics and optimized for Absolute Co-witness height, this mount is a top-rated choice among professionals seeking speed and reliability in the field.

## Description

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.
