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®, 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*.
- All Direct-to-Rail Mounted Optics. Optimized for Lower 1/3 Height Optics
- Note if using Absolute Cowitness Height Optics: If used in conjunction with one of our FAST FTC Magnifier Mounts, you will notice a minimal occlusion of the bottom of the sight picture when the magnifier is stowed.
*NOTE* FDE is used throughout our catalog to reference a spectrum of colors that include tan, brown, bronze, earth, and everything in between. Due to the chemical process that takes place during Type III Hardcoat, the final finish can vary from part to part (even parts done in the same batch). Therefore, your FDE product may vary from other parts from UNITY and other companies, and may vary from the photos shown online.
