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 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™ 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™ 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 cowitness” optics such as EOTech XPS®, Sig Sauer Romeo8H®, etc.  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*.

    I was on the fence until arrival and install with an eotech EXPS3-0. Went out to re-sight and *instantly* figured out the hype is legit. Height isn’t an issue and felt comfortable with my egg-shaped head. Ha. Later when the sun went down, back outside I went and used under my 31a’s and in every way night vision shooting and passive aiming was a dream. Get one for each of your dedicated nvg guns, you’ll be impressed and neck/shoulders less fatigued.

    2nd Unity Riser purchased. Got this one for a Vortex UH-1. Dig the FDE color and the function.
