How does a red dot sight work?
A red dot sight is simply an LED shining a beam of light onto a specially coated, slightly angled piece of glass. That That glass reflects the LED’s light, creating your dot. This allows you to see your reticle and see through your optic, but someone on the other side of the optic cannot see your reticle.
The size of a red dot is measured in MOA is controlled by an aperture hole in front of the LED. Bigger dots are quicker to see and get on target, smaller dots are better for shooting at moderate distances.
