Zero Tech Optics Thrive HD 1x 20mm Prism Dot Red Dot Sight

The Zero Tech Optics Thrive HD is a compact 1x micro prism sight designed to deliver red-dot speed with riflescope-grade optical clarity. Built around a 20mm objective lens with multi-coated HD glass, this optic produces a crisp sight picture and a generous 90mm eye relief for fast, comfortable target acquisition on AR-platform rifles, shotguns, and other long guns.

At the heart of the Thrive HD is the ZT Prism Dot reticle, a glass-etched aiming point that remains visible even without illumination so the optic stays usable should the battery be exhausted. When illumination is desired, the unit runs on a common CR2032 battery with 13 adjustable brightness settings (including three night-vision compatible levels) and battery life rated at up to 50,000 hours.

The housing is finished in black and engineered to be waterproof for reliable service in adverse conditions. Weighing just 8.80 oz, the Thrive HD keeps a compact footprint on the host firearm while delivering the rugged performance expected of a duty-grade aiming solution.
