The FAST™ FTC 4X is the first integrated magnifier available on the market, bringing the magnifier up to a 2.26″ optical centerline from the rail. Integrating the mount with the optic shaves weight, increases strength and ensures streamlined functionality with near-zero occlusion of the primary optic when stowed. The optical glass provides a clear and durable sighting solution while UNITY's FTC (flip-to-center) technology allows for easy stowage when not in use.Designed for use with a red dot mounted at the same height, the FAST™ FTC 4X provides ultimate picture clarity, utilizing the red dot in the primary optic as the aiming reticle. This allows the shooter to shift between non-magnified (stowed) and magnified aiming without re-zeroing the optic. The magnifier can be mounted on multiple weapons platforms behind a red dot sight or used as a hand-held monocular. It comes with an integrated FAST™ QD Lever that makes it even more low-profile.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.
