The ZeroTech Thrive HD Micro Reflex Sight Multi Reticle is a compact 1x red dot with a switchable reticle on the Shield RMSc footprint (ZeroTech part no. THDMM21). The multi reticle pairs a 3 MOA center dot with a 40 MOA outer ring and floating crosshairs, and a button press selects the configuration that fits the moment. ZeroTech presents it as a versatile choice that can be adapted to a pistol, rifle or shotgun. A 21mm objective lens, motion-driven auto sleep and auto on, and adjustable brightness round out the package. The housing is aluminum with an IPX7 waterproof rating.
