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.
The FAST™ Absolute Riser comes standard with a rail clamp and is compatible with our ADM QD lever kit (sold separately). The FAST™ Absolute Riser is built from 7075-T6 Aluminum and Type III Hardcoat Anodized Black or FDE*.
