The Unity Tactical FAST Thermal Riser provides an elevated mounting foundation designed specifically to bring thermal imaging hardware up to a modern 2.05-inch optical centerline height. This tactical elevation allows thermal devices or clip-on systems to align perfectly with primary optics housed in matching FAST LPVO or COG series mounts. Built to optimize user ergonomics, the tall profile facilitates a natural, heads-up posture that remains comfortable when operating alongside night vision equipment, helmets, and heavy protective gear. The compact chassis is machined entirely from premium 7075-T6 aluminum and occupies only three slots of rail space to maximize handguard configuration options. Complete with a resilient Type III hardcoat anodized black finish, it ensures dependable zero retention and extreme structural durability under constant heavy recoil.
