Questions & Answers
Battery life? Expert Answer

Will this optic fit on an FN 509 tactical compact without an adapter plate? Expert Answer

Helpful Positive Review Good mini RDS for money by BH822, December 31, 2022
This RDS seems very robust, has clear glass and looks good. The only feature that would be an improvement would be to have battery access without having to remove the sight. This sight mounted quickly and was easy to zero. This is my seventh RDS and...

Helpful Positive Review Crimson Trace Green Dot by TW, April 4, 2023
Nice unit for the money got as crisp as a Holosun but about $100.00 cheaper. Like the built in co witness. Does have difficulty with the auto brightness when in the dark looking out to a brighter spot.

Product Info for Crimson Trace CT-RAD Micro Reflex Green Dot Sights

The CT RAD Micro (Rapid Aiming Dot) Electronic Sight is an ultra-compact Open Reflex Sight for compact and subcompact pistols. Featuring a green 5 MOA aiming dot, the CT RAD Micro has a recessed and fully multi-coated lens with a large quick acquisition window. The CT RAD Micro comes with the CT RADIANT Ambient Light Sensor that automatically adjusts the aiming dots brightness to the surrounding lighting condition. 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.image

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.
