Unity Tactical's FAST is a series of optic mounts and platforms that provide end users with a quicker sight picture than standard height mounts. Other risers have been on the market before but the Unity FAST is simple, lightweight, modular, and affordable -- easily beating the competition for duty grade riser components.
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 Optic Riser (P/N: FST-ORB) 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.
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 (sold separately) is 100% compatible with existing Offset Front Sights such as those available from MAGPUL, Dueck Defense, Midwest Industries, and Knights Armament Company.
