The CT RAD Micro Pro (Rapid Aiming Dot) Electronic Sight is an ultra-compact Open Reflex Sight for compact and subcompact pistols. Featuring a red 3 MOA aiming dot, the CT RAD Micro Pro has a recessed and fully multi-coated lens with a large quick acquisition window. The CT RAD Micro Pro comes with the CT RADIANT Ambient Light Sensor that automatically adjusts the aiming dots brightness to the surrounding lighting condition. The CT MOTION Sensor detects movement of the firearm and automatically turns the reflex sight on. The sight powers off after 2 minutes of zero movement. The Micro is easily installed on an optics cut slide using the CT micro footprint that is also compatible with the Shield RMS and JPoint footprints. The Micro has a rear sight notch cut into the back to line up with your front iron sight. Made of 7075 Series Aerospace Aluminum, it is 30% stronger than most industry standard sights made with 6061 Series Aluminum. The entire CT RAD family has an Innovative top strap design that deflects force if the sight is dropped. Our engineers developed a better way to reduce stress on the lens of reflex sights. By combining out-of-the-box thinking with next-level physics, we designed a system that both re-enforces your optic and reduces stress if it happens to get dropped. All this comes with our CRIMSON Protect Lifetime Warranty.
