Zero Tech Optics Thrive HD Features The Zero Tech Optics Thrive HD delivers a 3 MOA green dot reticle through a 28mm by 20mm objective window giving a crisp and precise aiming point that is fast to pick up during rapid target transitions. Green dot illumination offers strong contrast and visibility across a wide range of lighting conditions which is valuable for shooters who train and carry in varied environments from bright daylight to dim indoor settings. Eleven brightness settings allow the dot intensity to be tuned to the ambient light keeping the reticle visible without washing out the sight picture. An unlimited eye relief design means the shooter can achieve a fast sight picture regardless of head position which speeds up target acquisition in dynamic shooting scenarios. Built from an aluminum housing and finished in Flat Dark Earth the Thrive HD uses the RMR footprint which means it mounts directly to the wide range of pistol slides and mounting plates already cut for that standard. Digital controls with automatic on and off help preserve battery life and a rated 50 000 hour runtime on a single CR2032 battery means the sight can be mounted and essentially forgotten between changes. At 1.78 inches long 1.55 inches tall 1.28 inches wide and just 2.58 ounces the sight adds minimal bulk or weight to a carry or duty pistol. Fully multi coated optics keep the sight picture bright and clear making the Zero Tech Optics Thrive HD a well rounded reflex sight for sale at GrabAGun for pistols and sub-guns alike.
