FAST(TM) 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 earpro/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(TM) Riser securely elevates block-type red dot optics with a standard lower 1/3 cowitness picatinny mount to a 2.26 optical center line. FAST(TM) Riser provides an elevated M1913 Picatinny platform for direct attachment of optics such as EOTech EXPSA(R), Leupold LCOA(R), Vortex UH-1A(R), and other "lower 1/3" optics*. *Technically, the FAST(TM) Riser will support "absolute cowitness" optics such as EOTech XPSA(R), Sig Sauer Romeo8HA(R), etc. But, compatibility with the FAST(TM) FTC Magnifier Mount will be limited. The FAST(TM) 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(TM) 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(TM) Riser is built from 7075-T6 Aluminum and Type III Hardcoat Anodized Black or FDE*.
