The Aim-O RD-1 Red Dot Black is a low profile red dot that allows you to choose between using a red dot or a green dot.
This red dot sight has a metal housing which makes it very robust. The dots have 5 brightness settings so it is good to use both indoors in the dark and outdoors in the bright sun. The sight fits on most RIS rails and can be attached with an Allen key. Because this reddot has a low mount, it is ideal for airsoft guns like the G36 that have a raised rail.
Windage & elevation adjustment is also available so you can adjust the dot perfectly where the bb hits the target.
Furthermore, this sight works on a CR2032 battery which is not included with this sight.
