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.
