Zero Tech Optics Thrive HD Features The Zero Tech Optics Thrive HD centers on a new multi reticle system that offers three optional reticle patterns giving the shooter a choice between a precise 3 MOA dot and broader aiming references for faster target acquisition. Eleven brightness settings let the sight be dialed from dim indoor ranges to bright outdoor sun keeping the reticle crisp without washing out. Shake awake technology shuts the unit down automatically after inactivity and snaps it back on the instant the sight moves so the shooter never has to fumble for a power switch mid draw. A rated battery life of up to 50 000 hours on a single CR2032 cell means years of service between changes for most shooters. Built on a popular RMR footprint the Thrive HD mounts directly to most pistols and rifles already cut for that pattern and it ships with a dual bolt low mount base for picatinny rails to extend that compatibility further. An anodized aluminum housing backed by a molded rubber cover gives the sight real protection against drops and rough handling while the shock proof and waterproof rating lets it stand up to field conditions and range abuse alike. Multi coated lenses cut glare and improve light transmission for a clear undistorted sight picture in varying conditions. Rounding out the package are a cleaning cloth and mounting tools making the Zero Tech Optics Thrive HD a ready to mount duty capable reflex sight for sale at GrabAGun.
