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 gas 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 Riser securely elevates block-type red dot optics with a standard lower 1/3 co-witness Picatinny mount to a 2.26? optical centerline. FAST Riser provides an elevated M1913 Picatinny platform for direct attachment of optics such as EOTech EXPS, Leupold LCO, Vortex UH-1, and other lower 1/3 optics*.
*Technically, the FAST Riser will support absolute co-witness optics such as EOTech XPS, Sig Sauer Romeo8H, But compatibility with the FAST FTC Magnifier Mount will be limited.
The FAST Riser comes standard with a rail-grabber clamp. A Flip-Up Offset Backup Rear Iron Sight module can be purchased separately. This feature will provide fast-transition BUIS capability to the FAST Riser. The Offset Rear Iron Sight Module is 100% compatible with existing Offset Front Sights such as those available from MAGPUL, Dueck Defense, Midwest Industries, and Knights Armament Company.
The FAST Riser is built from 7075-T6 Aluminum and type III Hardcoat Anodized Black or FDE*.
