The 8 Best Red Dot Sight for Every Occasion and Budget

Red dot sights can help you take your shooting to the next level but finding the one that’s right for you can be like searching for a needle in a haystack—there are just so many options out there and it’s natural to feel lost. That’s why I’ve put together a list of the 8 best red dot sight on the market and will discuss what makes each one stand out. Whether you’re a seasoned marksman or a weekend shooter, this guide will help you find the right red dot sight for your needs.

Using A Red Dot Sight

Red dots excel in environments where the ranges are moderate and speed rules. The generous, often unlimited eye relief makes them fast to get behind and fast to get on target. Picture this: you’re at the range, lining up your shot, and BAM – your target is right in your crosshairs without a second thought. That’s the magic of a great red dot sight. It removes the time it takes to align sights properly and makes shooting fast and accurate.

Obviously, the use of defensive and duty weapons makes them faster and easier to react with. Red dots rock out to 200 yards and outperform iron sights to a crazy degree. A smaller dot reticle makes it easier to see targets at a distance, and the fast the reticle glows makes it easy to use in any environment. Ofcourse, they are great for range shooting but here are some other things you can do with your red dot;

• Home defense: If I was outfitting a rifle or shotgun for home defense, I don’t see any good reason to use anything other than a red dot. LPVOs rule in terms of versatility, but that means nothing when the farthest shot in your home is 15 yards.
  
• Concealed carry: Red dots come in various sizes and are popular on handguns, from SOCOM gunslingers to average concealed carriers. Mini red dots enhance pistol capability, making it easier to shoot faster and more accurately, extending effective range. They add a bit of height and weight but are worth the increased capability.
  
• Piggybacking: Mini red dots are excellent backup optics for magnified rifle optics like LPVOs and Prism sights. They can be offset at a 45-degree angle or placed on top, providing an immediate close-quarters option.

As you can see, red dot sights are extremely versatile. However, what might be the perfect red dot for someone who uses it primarily for piggybacking won’t be the right fit for someone who is looking to outfit their concealed carry gun. That’s why I spent a lot of time classifying the red dot sights I tested into their best fit category. Here’s how I went about testing these red dots.

How I Set Up to Review the Best Red Dot Sights

As someone who has written hundreds of articles on weapons and equipment, I’ve had the privilege of not only owning many red dots, but also have been sent many by the companies, and even tested some at media events (of which a couple of those lead me to purchase some).

However, before writing this article, I wanted to make sure I wasn’t missing anything. So, I talked to a couple of colleagues about certain sights I hadn’t gotten my hands on and got their input as well. Because of this, I was able to put together a comprehensive list of the top red dot sights and will try to tailor them based on specific needs and uses like ROI, top quality, caliber, etc – because let’s face it, there isn’t such a thing as the perfect red dot for every person or situation.

Now that you know how I tested them, let’s jump right into my selections.

Reviews of Our Best Red Dot Selections

Why Use an Aimpoint CompM5b?

When it comes to red dot sights, the Aimpoint CompM5b is hands down my favorite. I’ve tried many, but this one tops them all and earns the “Best Overall” spot in my book.

Right out of the box, the CompM5b’s bombproof design caught my eye. Aimpoint is known for making durable optics, and this model lives up to that reputation. I’ve seen older Aimpoints like the M3 still in action after decades, and I believe the M5b will last just as long.

One of the standout features is its Ballistic Drop Compensator (BDC) turret. On my AR-15, the 5.56 turret lets me easily adjust for different ranges. Whether aiming for 300 yards or accounting for bullet drop, the precision is incredible, especially with a magnifier.

The 2 MOA red dot reticle is another highlight. It’s clear and crisp, making target acquisition fast and precise. The glass clarity is top-notch, like looking through a high-definition lens. This optic is versatile for both close-quarters and medium-range engagements, with minimal parallax and almost no thermal drift.

Reliability is key, and the CompM5b delivers. It performed flawlessly across various rifles over several months. With a 50,000-hour battery life on alkaline batteries, and even longer with lithium, I never worry about it dying on me.

Adjusting the turrets using the reverse side of plastic caps can be a bit fiddly, but that’s a minor gripe. The flip-down lens covers are a great touch, keeping the lenses protected and ready.

Its brightness settings are versatile, adapting to different lighting conditions, including night vision. This adaptability makes it reliable in any environment.

The Aimpoint CompM5b is worth every penny. It excels in extreme conditions and elevates my shooting experience. Don’t let the price scare you off; it’s a solid investment. Give it a try and you won’t be disappointed.

Why Use a Sig Romeo5?

The Sig Sauer ROMEO 5 is my favorite budget-friendly red dot. I’ve used it extensively, and it’s impressed me enough to earn the top spot in my red dot list.

At first, I was skeptical about its quality and durability compared to pricier options like Aimpoint. But after taking it to the range multiple times, it won me over with its user-friendly design.

It might not be on par with Aimpoint, but the ROMEO 5 holds its own with a remarkable 40,000-hour battery life. The 2 MOA dot adapts well to different light conditions, and the shake-awake motion activation is a game-changer, saving battery life without needing manual activation.

While it’s not meant for long-range shots, it performs exceptionally within its 100-yard range. I’ve tested it extensively, firing around 200 rounds, and it held zero flawlessly every time.

Although I haven’t clocked hundreds of hours with it yet, the ROMEO 5 has been rock-solid for me over the past couple of years.

Compared to similar models like the Vortex Sparc, the ROMEO 5 wins on price, usually coming in about $40 cheaper. So if you want quality, durability, and capability without spending a fortune, the ROMEO 5 is a solid pick. It’s a great alternative if you can’t afford an Aimpoint.

Why Use an Aimpoint Acro P-1?

When it comes to choosing the best red dot sight for handguns, my top pick is undoubtedly the Aimpoint Acro P-1, and here’s why.

First and foremost, the Acro P-1 has set new standards by introducing an enclosed emitter design tailored for handguns. Having experienced its performance firsthand, I can attest to the seamless integration of this optic with a pistol. The Acro doesn’t compromise on reliability, delivering the rock-solid performance expected from an enclosed optic.

Sure, it’s a tad bigger and heavier than some other compact red dots, but that’s actually a plus for duty use, making it my go-to in this category. Its tough build and adherence to strict durability standards mean it’s not just for concealed carry but excels in professional settings too.

What I love is the side-mounted battery compartment, making battery changes a piece of cake. Plus, the brightness adjustment controls are not only easy to reach but also don’t mess with your sight picture or grip. That, combined with a two-handed grip, makes it easy to use in any shooting scenario.

With its 3.5 MOA dot, the Acro gives crystal-clear clarity at handgun ranges, ensuring a spot-on sight picture every time. And it’s not just for handguns; I’d confidently throw it on a rifle or shotgun too. Its rugged design and reliability make it my top pick for all sorts of shooting situations.

So, if you’re after a red dot sight that brings together reliability, versatility, and durability, the Aimpoint Acro P-1 is the one to go for, even if it’s a bit pricier.

Why Use a Trijicon RMR?

When it comes to piggybacking optics, the Trijicon RMR is my top choice. As a Marine, I’ve relied on it in the field, and it’s proven itself time and again as not just a red dot, but a trustworthy companion.

Mounted on my machine gun day optic, the RMR has shown unbeatable durability and a straightforward design, making it a go-to for various firearms. Its widespread compatibility and dominance in the mount market make it perfect for piggybacking, seamlessly integrating with LPVOs, ACOGs, and even offset at a 45-degree angle for maximum versatility.

The 9 MOA dot has been my personal preference, aiding in rapid target acquisition in dynamic scenarios. With crystal-clear optics and the ability to withstand recoil, the RMR enhances situational awareness without any flicker or distortion.

Its automatic brightness adjustment is a game-changer, ensuring the dot is always perfectly matched to ambient lighting, crucial for concealed carry scenarios. And let me tell you about durability—this thing can take a beating. I’ve seen it tested in real-life situations by folks in the military and law enforcement, and it always comes out on top.

With different dot sizes and a long-lasting battery, the Trijicon RMR Type 2 is the real deal. It’s tough, reliable, and spot-on accurate, whether you’re a pro or just out having fun.

Why Use a Holosun 507C?

The Holosun 507C has really earned its spot as my top pick for shotguns, and let me tell you why.

First off, Holosun delivers quality optics without the hefty price tag, and the 507C is no exception. But don’t mistake affordability for cheapness—it performs like a champ.

Mounted securely on my Benelli M4, the 507C’s versatile reticle system is what sets it apart. With options like a 2 MOA dot, a 32 MOA circle, and a combo of both, it caters to different shooting styles. Personally, I love the 32 MOA circle! It helps me pattern my shotgun load perfectly, keeping every pellet within the circle’s bounds, especially crucial for home defense.

This optic is tough too. It’s endured over 1,500 full-powered shotgun loads without a hitch, showing its durability. And the 32 MOA circle? It speeds up target acquisition, perfect for high-stress situations.

Reliability? Check. The 507C has been through it all—500-round burn tests, shoulder-height drops—and still comes out on top. Even with a cracked lens, the reticle kept on going, proving its robust design.

Plus, the battery life is impressive. It can hold up to 10,000 hours on a medium setting. Also, with features like solar failsafe and shake-awake technology, it’s always ready for action.

The auto-brightness feature is a game-changer too, seamlessly adjusting to different lighting conditions. And the roomy window size? It gives you a clear view, making your shots fast and precise.

Overall, the Holosun 507C balances performance and affordability perfectly, making it the best choice for shotguns in my book. It’s reliable, tough, and won’t break the bank,which makes it a must-have for any shooter.

Why Use a Holosun 507K?

When it comes to micro red dot sights for subcompact handguns, the Holosun 507K stands out as my top choice. Its clarity is impressive, offering both a 2 MOA dot and an optional 32 MOA circle for a clear sight picture, essential for quick target acquisition during the draw. While it may take a bit of adjustment for those used to larger sights, it proves highly effective with practice.

The lens delivers a clear view with just a subtle blue tint, and it adds minimal bulk to subcompact handguns, maintaining their sleek lower profile. What really sets the 507K apart is its versatility, thanks to its multi-reticle system. Whether you prefer the 32 MOA circle, the 2 MOA dot, or a combination of both, it’s adaptable to various shooting styles.

During testing, the 507K proved its durability, holding zero even after firing thousands of rounds. The two-button control system makes brightness adjustments quick and easy.

While it’s not without its quirks—like a slightly reddish dot and a shorter battery life than advertised—the shake awake feature, although sensitive, didn’t impact performance during rapid movements.

Overall, the Holosun 507K is a top-tier micro red dot sight for subcompact handguns, earning its spot as the “Best for Subcompact Handguns” in my book. If you’re after a reliable and versatile optic for your subcompact, the Holosun 507K is the way to go.

Why Use a Trijicon MRO?

For a red dot sight that combines reliability with affordability, look no further than the Trijicon MRO. It’s my top choice for those seeking professional-grade performance without breaking the bank.

I was immediately impressed by its optical clarity, although there’s a subtle bluish tint indoors. Nonetheless, its bombproof construction guarantees durability, meeting professional standards for submersion and shock.

Despite its reasonable price, the MRO doesn’t skimp on quality. It offers a crystal-clear sight picture and multiple brightness settings, ensuring adaptability in various lighting conditions.

While it does exhibit a slight fish eye effect on the sides, it’s a minor consideration given its overall performance. It maintains zero consistently, even when mounted on a shotgun.

With its adjustable brightness settings and rugged build, the MRO excels as a duty-grade red dot sight. Whether you’re in law enforcement, the military, or a civilian shooter, it’s a dependable optic that delivers without compromise.

Why Use a Bushnell TRS 25?

Who would’ve thought you could get so much quality for under a hundred bucks? The Bushnell TRS-25 blew me away with its value. It’s not top-tier, but it’s a solid choice for your beater rifle, shotgun, or even some handguns.

For a plinking rifle, the TRS-25 is hard to beat. It doesn’t have the best clarity or features, but it gets the job done. It holds zero well and can take a beating – drops, falls, and even a bit of water.

The 3 MOA dot is sharp and easy to see, ensuring quick and accurate shots. I’ve used this optic in various lighting conditions, from bright sunny days to gloomy afternoons, and the red dot remains consistently visible. With 11 daylight brightness settings, it adapts to different scenarios. While it lacks night vision compatibility, its performance in daylight is stellar.

The TRS-25 is also lightweight at just 4.2 ounces with the battery. This makes it great for those who value maneuverability. I’ve had it on my AR-15 for the past six months, running it through drills and cold weather, and it hasn’t let me down.

So why is it the “Best Budget Red Dot”? The TRS-25 offers excellent features for its price. The 3 MOA dot reticle is versatile and ideal for close-quarters. It’s compatible with a range of firearms, making it a great budget choice.

One drawback is that it doesn’t come with a riser mount, which might be inconvenient for some. But for its price, the Bushnell TRS-25 is an unbeatable option for a reliable, budget-friendly red dot sight.

Best Red Dot Sight Buyers Guide

When it comes to choosing the right red dot sight for you, there are several factors you have to take into consideration. Sure, you’ll need to know what gun you’re actually going to mount it on. And yeah, you’ll need to be able to afford it.

But beyond that, what should you look for?

Let’s take a look at some commonly forgotten factors you’ll need to look at before purchasing your red dot optic. 

Open Or Enclosed Emitters: Red dots come in two types: open and enclosed emitters. Open emitters, like those on the Trijicon RMR and Holosun 510C, have an exposed emitter with a single lens. They’re reliable but can get obstructed by dirt, dust, snow, or rain. However, they are smaller, lighter, and have less distortion.

Enclosed emitters, common in long-gun red dots, house the emitter inside the optic with two lenses. This design protects the emitter from elements like snow and rain but adds weight and potential distortion.

Magnifier Compatibility: Magnifiers boost your red dot’s magnification, increasing effective range. Most long-gun red dots work with magnifiers, but micro red dots and some budget optics might not. Ensure your red dot’s height matches the magnifier, or be ready to change mounts.

Dot Color: Reticles come in red, green, amber, and blue. Green reticles use less battery power and last longer. Red contrasts well against most backgrounds. Green and red are mostly a matter of personal preference. Amber can wash out in daylight, and blue is rare.

Reticle Design: While many red dots are simple dots, some, like those from Holosun and SIG, use circle and dot combinations. These are larger and easier to see, especially for those with astigmatism. Rifle red dots are usually 2-3 MOA for precision, while handgun red dots range from 3.5 to 9 MOA for quick target acquisition. Shotguns and pistol caliber carbines can go either way. However, there are pros and cons to big and small red dot sizes.

Mounting Considerations: Long guns typically use a Picatinny mount. Handgun red dots often require slide milling or a plate system, as dovetail mounts are less ideal. Shotguns benefit from low mounts for co-witnessing and stock design, while tall AR mounts usually don’t work well.

Final Thoughts

Rarely can an accessory improve actual performance. Red dots break the mold and allow even average shooters drastic increases in speed, accuracy, and overall performance. However, choosing a red dot sight is not just a matter of following the crowd—it’s a strategic decision based on performance, speed, and adaptability. Hopefully, I’ve left you with enough information to find the right red dot for you. Happy shooting.

Best Red Dot Sight – FAQs

Are Holographic Optics Red Dots?

They are not red dots in the strictest sense. Holographic optics like the Eotech series and the Vortex UH series often get lumped into the world of red dots. They often function like red dots and provide similar performance once lead starts meeting steel; however, they utilize a different method to obtain their reticles.

Can I use a red dot sight with magnifiers for longer-range shooting?

Yes, many red dot sights are compatible with magnifiers, allowing for improved accuracy at longer distances. Ensure that the red dot sight you choose is designed to work seamlessly with magnifiers, and consider factors such as eye relief and mounting options for optimal performance in extended-range shooting scenarios.

What reticle size is ideal for different shooting scenarios?

The ideal reticle size depends on the shooting scenario. Smaller reticles are suitable for precision shooting, while larger ones excel in fast-paced, close-quarters situations. Consider the intended use of your firearm and choose a red dot sight with a reticle size that aligns with your shooting preferences and requirements.

How do I know if a red dot sight is compatible with my firearm?

Check the specifications and product details provided by the manufacturer to ensure compatibility with your firearm. Look for information on mounting systems, co-witnessing options, and any specific requirements. If in doubt, consult with the manufacturer.
