FAST is a series of optic mounts and platforms that provide end users with a quicker sight picture than standard height mounts. The FAST Micro Mount creates a 2.26in optical center line from the rail and provides faster/easier dot/reticle acquisition while wearing night vision goggles, gas masks, plate carriers, and other gear. FAST mounts allow for more rapid visual processing of the battlefield by promoting a heads-up posture. The FAST Micro-S Mount is specifically designed for the Aimpoint CompM5s, CompM5b, and Duty RDS mini red dot sights. It puts these taller micro sights at the established FAST height and is fully compatible with the entire line of FAST Magnifier Mounts. The FAST Micro-S Mount can also be fitted with a Quick Detach Lever (sold separately).
