Best Red Dot Sights – Top 11 For 2021

When it comes to the confusion of purchasing any shooting related accessory, nothing can beat the red dot sight as it is one of the most overlooked accessories in the kit.

People usually shell out all their money into the rifle that the accessories are mostly overlooked, and the red dot sight is mostly neglected.

But when you look at it from a different perspective, it is one of the most important accessories which will help you get proper accuracy while aiming.

So, we would like to bring to your attention that you should give closer attention whenever you purchase a red dot sight.

A quality red dot sight is a valuable asset for many shooters. These highly functional firearm accessories decrease the amount of time it takes to get on target, strengthen and refine your aim, and increase accuracy.

Red dot sights were originally developed for the battlefield and are ideal for close to medium range shooting.

They are relatively simple optics with relatively simple reticles. However, they are designed to help you do the not-so-simple job of getting on target quickly (and staying there).

The earliest red dot models were massive, highly expensive, and impractically delicate. However, the same technological advancements that morphed the bulky mobile phones of the 1980s into the iPhone in your pocket, have also worked their magic on red dot optics.

Modern red dot sights are compact, solid, and lightweight. You can even purchase a quality red dot sight for significantly less than the cost of the latest iPhone.

Because technology has made red dots practical and affordable, there are a ton of options available to the modern shooter. Fortunately, this means they are available across budget ranges and in various sizes, shapes, and styles.

Best Red Dot Sight 2021

If you are in the market for a red dot optic, there are a few that really rise above the rest. Here is a list of what we consider the cream of the crop when it comes to the best red dot sights of 2021.

Aimpoint M4 

Aimpoint produced the very first red dot optic way back in 1975. They have been refining and perfecting red dot technology ever since. The Aimpoint model M4 is the current red dot optic used by the United States Army. For civilian shooters and law enforcement personnel, Aimport developed the Aimpoint Pro, which sits firmly at the top of our list.  

The Aimpoint PRO sits at the top of our list because it excels at everything from recreational plinking to full-blown combat. However, although this thing will help you easily pop cans off fence posts, it was really designed for war. It is bombproof, waterproof (up to 150 feet), and has an operating range of -49 to 160 degrees Fehrenheit. 

Basically, the Aimpoint PRO will stand up to anything you can dish out. Drop it from a building, smash it with a hammer, it doesn’t matter. If your shooting takes you to the North Pole or Death Valley, this thing will still perform. It’s also guaranteed to handle more recoil than you can.

The Aimpoint PRO also comes with a three-volt lithium battery that provides 30,000 hours of continuous use. That means you can leave it on and you’ll still only need to change the batteries about every 3 ½ years!

Bushnell TRS 25

Not every shooter can afford to fork out several hundred dollars for a red dot sight. Don’t worry, Bushnell has you covered. This compact, affordable red dot optic generally sells for around $50. (If you find something cheaper, think twice before you buy it.) 

Although economically priced, the Bushnell TRS 25 offers some surprising features, including amber coated lenses for easy low light shooting. It’s also fogproof, waterproof, and shockproof. We honestly don’t know how Bushnell is making any profit on this quality optic.

Vortex Venom 6 MOA

The smallest and lightest red dot on our list is the Vortex Venom. This open red dot sight can easily pull double duty, working equally well on either your pistol or rifle. 

We’re excited about this quality red dot for plenty of reasons. It comes in two dot sizes – 3 MOA and 6 MOA, has an auto brightness feature and ten manual brightness settings.

Also, the Venom automatically shuts down after 14 hours to conserve battery power, just in case you forget to turn it off. However, when the battery does run out, it is easy to access from the top of the sight.

There’s no need to remove the Venom for a routine battery change, so you won’t have to re-zero before you head back out to the range.

Although technically a “holographic” sight, we’ve included the EOTech EXPS-2 because it serves the same general purpose as a red dot optic.

It just utilizes different technology to get the job done. (It also makes our list because it is seriously cool!)

The EOTech name is largely identified with holographic sights. The company actually pioneered the common holographic reticle design which features a large 68 MOA circle with a smaller 1 MOA center.

This combination helps balance quick target acquisition with precision shooting. It’s like getting the best of both worlds.

Holographic sights are notorious for draining batteries. Be prepared to change them more often than a standard red dot. However, the EXPS-2 should give you about 600 hours before you’ll need to switch out the batteries.

Sig Sauer SOR43031 Romeo4T Black

Sig Sauer is a respected name in the shooting industry and is known for producing quality, high-performance weapons and accessories.

The quality of the Romeo 5 red dot sight goes without saying. (Actually, the quality is implied when you say the company’s name). 

Perhaps the coolest feature of the Romeo 5 is the Motion Activated Illumination (MOTAC) feature. The optic actually switches on automatically when it senses motion. It also automatically turns itself off if left alone.

When left on, the optic enters a sort of sleep mode, where the red dot is shut off but will instantly turn back on when motion is detected. That’s a pretty handy feature for those of us who often forget to turn things off when we finish with them.

The Trijicon RMR Type 2 is compact, lightweight, waterproof, and night vision compatible. It also has a four-year battery life, so you can just turn it on, forget it, and it will always be ready to go.

Buying guide – Things to look out for before purchasing a red dot sight

A Red Dot Sight might seem to be a small investment, and we see most people going for the one that is cheap. But in the end, they regret opting for that as it turns out, the red dot sight is an integral part of the accessories needed for hunting. So, to make you aware of the aspects to look out for when you are planning on purchasing a new red dot sight for your gun, we have come up with a comprehensive guide. By the time you finish reading this, you will know the features which a red dot sight should have if you want it to perform well.

Dot Size – The dot size is very important when you are going to purchase a red dot sight. If the dot is too large, you will not be able to aim at targets which are at a closer distance, and if it is too small, you would not be able to see it on targets which are further away. So, find the dot size which would be appropriate for you and make the decision.

Reticle – most of the reticle will illuminate in low light settings. It is not a feature which is important if you are someone who hunts during daylight. But if you do hunt at night, the reticle should support low light settings and have a night vision compatibility would also be of much help. Find out the reticle patterns which suits your needs and maybe try it out before you make a purchase.

Durability and Weight – The weight and durability are two important factors which make or break red dot sights. If you have an amazing scope which delivers great performance but if it is heavy and cracks easy, then there is no point in having it. Make sure to get a red dot sight which is a combination of both – great performance and lasts for long without giving you trouble once it is mounted to your gun.

Power and Battery – Battery life is something which many do not take into consideration while purchasing a red dot sight. Once they have bought it, they figure it does not hold the battery very well. This will have you change the battery in between the hunting trips or having to go back from the trip because you only battery died. So, get a scope which has great battery life.

After all, you are the one who is buying the red dot sight. It should get along with every feature you expect it to deliver. So, make sure you take into account all the factors which would bode well with your requirement and the type of gun you own.
