FAST 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 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. The FAST MRO Mount features a built-in standard height windage-adjustable back up rear iron sight that keep weapons uncluttered, without reducing capability. It also features the FAST offset accessory mounting interface.
