Unity Tactical FAST Accessory Riser – BlackThe smaller cousin of the FAST Optics Riser, the Unity Tactical FAST Accessory Riser is a versatile tool that raises a variety of optics, thermals and lasers to give you a heads-up posture. Featuring a machined slot for cable routing, it is primarily designed to raise a rail-mounted laser by 0.725″. Covering only three slots on an M1913 Rail, it creates a 2.26″ optical centerline from the rail when paired with then Leupold LCO. It also brings the Trijicon SkeetIRx or the Pixels on Target VooDoo-S to a 2.26″ optical centerline when those thermals are mounted on a UNITY CTM. It comes standard with a 2 cross bolt rail clamp.FAST is a series of integrated optics and optic mounting solutions that provides end users with a quicker sight picture than standard height mounts. FAST mounts position most optics at a 2.26” optical centerline from the rail, which allows for more rapid visual processing of the battlefield by ensuring an ergonomically correct heads-up posture. Further, they provide faster and easier dot/reticle acquisition while wearing night vision goggles, protective masks, plate carriers and other gear.SpecificationsHeightRaises Lasers and Optics by 0.725”Places Compatible Optics at 2.26” to Optical CenterlineCompatibilityRed Dots: Sig ROMEO8T, Leupold LCOThermals: Thermals mounted on Unity CTMLasers: Most rail-mounted lasersRail Mount2 Cross Bolt Rail ClampMaterial7075-T6 AluminumCoatingType III Hardcoat AnodizedWeight
