A red dot or green dot sight on an air rifle or air pistol provides faster target acquisition and better accuracy when shooting. Most dot sights lack magnification, but there are models with weak fixed magnification to provide better visibility at longer distances.
The choice between red or green dot is mainly a matter of lighting conditions. Green dot is more clearly visible in bright light, while red dot often works better at dusk. Many models have adjustable brightness, which makes it easy to adapt the sight picture to the surroundings.
There are dot sights for Weaver, Picatinny and Dovetail mounts, which makes it easy to mount them on different air guns. Weaver and Picatinny are similar, but Picatinny has uniform notches, while Weaver has varying distances between the notches. Dovetail mounts are slightly narrower.
For those who want to shoot more precisely at varying distances, there are models with parallax compensation and fine adjustment of the dot. A good dot sight for an air rifle or air pistol can make a big difference in accuracy.
