ZeroTech Thrive HD 1x21mm Red Dot Sight – Multi Reticle

The ZeroTech Thrive HD Multi Reticle Micro Reflex Sight is built for shooters who want fast target acquisition without adding bulk to a compact pistol, home defense handgun, or backup optic setup. Its slim, lightweight housing keeps the sight fast on target while giving the shooter the option to switch reticle patterns to match the scenario at hand.

This 1x reflex sight uses a 21mm x 15mm objective window with a multi-layer coated lens for a clear, sharp sight picture in changing light. It runs on Shake Awake technology with an auto-sleep, auto-on motion sensor that fires up the dot the moment the pistol moves and conserves battery when it's sitting still. The sight is built on the Shield RMSc footprint for straightforward mounting to RMSc-pattern slides and bases, and it ships with a rubber protective cover, a microfiber lens cleaning cloth, hex keys, and three sets of mounting screws.
