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 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.
