Reflex sights are optical devices that allow the user to look through a partially reflecting glass and see an illuminated aiming point. These days, reflex sights have an aiming point that is almost always a red dot projected by an LED, or a red dot encircled by a ring (and other configurations), and are highly durable with extremely long battery life.

By removing the planes of focus found in traditional iron sights, the reflex sight’s single, parallax-free virtual projection is always in focus with the target regardless of the user’s head position, making it ideal for shooters of all experience types.

The best reflex sights are those that offer fast target acquisition (with high accuracy) and ease-of-use for hunting, target shooting or law enforcement/military applications. They should have wide open fields of views (in the case of HUD reflex sights), and the ability to maintain a constant zero aiming point position under the relentless duress of firing in adverse conditions.

Most reflex sights have open HUD (heads up display) designs while some are tube shaped. The differences between the two will be explained in the subsequent product reviews, but you should know that the term “reflex sight” (or reflector sight) refers to an open/tube optic that usually has red dot reticle patterns, while a “red dot sight” does not always refer to a reflex/reflector sight.

Moreover, open reflex sights usually have a wider field of view (FOV) whereas tube reflex sights have brighter aiming reticles and a propensity towards more precise long-range targeting.

These are some of the best reflex sights on the market, offering all kings of technological innovations that enhance operation and durability in a full range of lighting/terrain conditions:

This optical device is a result of decades of meticulous design partnerships with military, law enforcement, and competitive shooters to develop the most innovative reflex sight on the market.

Adjustable LED sights are compatible with night vision applications (3.25 MOA dot size is the most popular).

The red dot is small enough for long range shooting and big enough to acquire close range targets quickly (pistol-aim directly at the target with ease while ignoring front and rear posts). The parallax-free RMR Type 2 also includes upgraded electronics for harsh conditions and a proven performance on slide ride pistols and other small arms.

Final Thoughts

Reflex sights on the market today are extremely sophisticated and practical. You can mount them on almost any firearm for a variety of purposes.

They are either an open heads up display (HUD) or tube shaped, and most of them use some configuration of a red dot aiming point (and red dot reticle systems are better than ever). Moreover, you want your reflex sight to make sense, be easy-to-use, provide extreme durability/reliability, and enhance your target acquisition through improved accuracy and quickness.  Use them as a pistol option or something perfect for your tactical shotgun.

Whether you are needing self defense, target shooting, or hunting fast-moving game, there is a best reflex sight for your situation.
