Questions & Answers
Battery life? Expert Answer

The Crimson Trace CT-RAD Micro Reflex Green Dot Sight has a battery life of 7,000 hours (1+ year), and uses a single CR1632 battery that is loaded in the bottom of the optic.

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

The Crimson Trace CT-RAD Micro Reflex Green Dot Sights use the Shield footprint. It will mount to the FN509 Compact Tactical but you will need to use the compatible optic mounting plate from FN.

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...

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.

This CT-RAD Micro Reflex Green Dot is garbage. Does not interface with mount. Unit maybe warped. When I call Customer Support the guy wanted to argue with me about the unit I had in my hand. Not worth the time and/or energy to do anything but throw...

A must buy for pistols… by Duggi, Verified Owner, January 30, 2026
I got this on sale and man is it nice. Used an RMS adapter plate to connect it to my Ruger 5.7. The aesthetics are nice. There’s no overhang and it doesn’t look weird like some do to me. I had heard Crimson trace was one of the best brands to buy so ...

How important is the Green Dot rubber cover feature for you? by incognito335i, Verified Owner, December 16, 2025
My first Green Dot Sight. I like it better than the Red Dot Sight I previously had by Crimson Trace. The 1 detail thing I like about CT Red Dot over the Green Dot CT is that the Red Dot cover is made of plastic and fits snug over the Sight when not i...

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.
