UNITY Tactical FAST Absolute Riser Mount

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 ear pro/communications headsets, night vision goggles and protective 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) Absolute Riser securely elevates block-type red dot optics with an absolute co-witness height to a 2.26 optical center line. FAST(TM) Absolute Riser provides an elevated M1913 Picatinny platform for direct attachment of optics, such as EOTechA(R) XPSA(R), LeupoldA(R) LCOA(R) and other absolute co-witness optics. If you're running a lower 1/3 co-witness height optic, you need the FAST(TM) Optic Riser. Specifications: Dimensions: 3.50 (L) x 1.21 (W
