Zero Tech Optics Thrive HD 1x 21mm x 15mm 3 MOA Red Dot Reflex Sight

The Zero Tech Optics Thrive HD is an ultra-compact micro reflex sight built for optics-ready pistols and slim-line slide-cut platforms. Featuring a true 1x magnification with a 21mm x 15mm objective window and an industry-leading High Definition glass system, this optic delivers uncompromised clarity in a featherweight package weighing just 19 grams (0.67 oz).

At the core of the Thrive HD is a crisp 3 MOA red dot reticle with 10 adjustable brightness settings for fast, precise target acquisition in any lighting condition. The sight uses a multi-coated lens system for crystal-clear precision optics and an unlimited field of view with unlimited eye relief, allowing shooters to maintain full situational awareness and a natural shooting stance.

Built on the popular RMSc footprint, the Thrive HD drops directly onto a wide range of micro-compact and optics-cut pistols. Power is supplied by a single CR2032 battery, delivering an outstanding up to 150,000 hours of runtime. Integrated shake awake technology automatically activates the reticle with motion and an auto shutoff feature preserves battery life when the optic is idle.

The Thrive HD is engineered for real-world use with fog, shock, and waterproof construction, recoil-proof internals, and a moulded rubber cover for protection during carry and transport. Finished in matte black with a high see-through mount profile, this is a refined, low-profile red dot ready for daily carry, range work, and competition alike.
