Top 10 Best Reflex Sights and Most Popular AR Red Dots

For this review we looked at the top 10 best selling reflex sights and most popular red dots and see what makes them the most popular in 2020. Reflex sights are extremely affordable, the easy to manufacture design makes them cheap to build, and they provide fast target acquisition with unlimited eye relief while still allowing you to be fully aware of your surroundings when mounted on a rifle .

Reflex sight's are also very versatile. Their ultra lightweight and compact size make them the perfect hand gun sight. They allow the user to shoot straight and fast with repeatable accuracy at short to medium distance.

What is a reflex and red dot

A reflex sight is an optic that provides a curved partially reflective glass where a LED red dot reticle is projected forward from a point located behind the lens. That reticle bounces off of the glass, towards the users eye. Due to the reflex design, the projected, illuminated reticle is always parallel with the sight’s optical axis, giving the illusion that the reticle is in front of the viewer while on target.

The benefit is, regardless of head or body position, if you can see the illuminated reticle on the object then you are on target. Field of view isn't impaired like a conventional rifle scope so theres no loss of situational awareness.

It also uses very little energy to produce an aiming point. Basically you can leave a good quality reflux reflex on for months on end, and it's visible. While a reflex is a type of sight, a red dot is just the illuminated reticles color and shape. All of the reflex sights below have red dots.
