But when it comes to picking the perfect sight, a high-powered scope might not always be the answer. Red dot sights are gaining traction for their speed and ease of use on these rifles.

However, with various factors to consider like dot size, durability, and mount compatibility, choosing the best red dot for your .308 requires careful thought.

Let's delve into the key aspects to consider in your search for the ideal red dot sight to enhance your .308 rifle's performance.

Top 5 Best Red Dot Sights for .308

Aimpoint PRO

⁠

For my .308, I went all-in with the Aimpoint PRO red dot sight, and let me tell you, it's been a game-changer. This thing is built like a tank, perfect for the recoil of my rifle. It's taken everything I've thrown at it, from dusty range days to wet and wild hunting trips, without a single hiccup.

Top-Tier Features:

Battery Life King: They say it lasts 5 years on a single AA, and I haven't even come close to dimming it yet. No more scrambling for replacements mid-match.

Dot Perfection: The 2 MOA red dot is crisp and clear, day or night. It's small enough for precision aiming but big enough for fast acquisition. Plus, the ten brightness settings let me adjust for any lighting condition.

Built to Last: This sight is waterproof, fogproof, and practically bombproof. It's the kind of gear you can trust with your life, whether you're a pro or a weekend warrior.

Advantages on the Range:

Lightning Fast: Target acquisition is unbelievably quick with the red dot. No more messing around with lining up iron sights under pressure. It's especially helpful for close-quarters shooting.

Superb Accuracy: Don't let the red dot fool you. This sight is every bit as accurate as a scope, especially at closer distances where the red dot shines.

Both Eyes Open: Unlike a scope, you can keep both eyes open with the red dot, giving you superior situational awareness. This is a huge advantage in fast-paced shooting scenarios.

Downsides to Consider:

Pricey Piece: This sight isn't cheap, but for the quality and reliability, I consider it an investment.

Not for Long Range: While accurate at shorter distances, the red dot isn't ideal for long-range shooting where magnification is key.

Limited Field of View: Compared to a scope, the field of view with a red dot is smaller. It takes some getting used to.

Real-World Experience:

Out on the range, the Aimpoint PRO makes me a more confident and capable shooter. Picking up targets is effortless, and my shot groups have tightened up considerably. It's also a blast to use for close-quarters drills. The sight itself is lightweight and doesn't throw off the balance of my rifle.

Online forums are full of praise for the Aimpoint PRO. Users rave about its durability, battery life, and overall performance. Some folks mention a slight learning curve with the red dot, but everyone agrees it's worth the effort.

Overall, the Aimpoint PRO is a top-shelf red dot sight that perfectly complements my .308. It's a true investment in performance and reliability, and for me, it's been worth every penny.

Trijicon MRO

⁠

I've been using the Trijicon MRO on my .308 for a while now, and it's become my go-to red dot sight. Here's the breakdown from my experience:

Best Features:

Speed Demon: The MRO excels at quick target acquisition. The large viewing area and crisp 2 MOA dot let you get on target fast, especially at close and mid-range.

Built to Last: Trijicon is known for bombproof optics, and the MRO is no exception. The forged 7075-T6 housing is tough as nails, and it's completely sealed for water and dust resistance.

Both Eyes Open: Like all red dots, the MRO lets you shoot with both eyes open, which keeps your situational awareness on point. This is a huge advantage, especially in dynamic shooting situations.

Advantages for .308:

Perfect for hunting: The MRO's lightweight and unobtrusive design makes it ideal for a hunting rifle without throwing off the balance.

Fast on hogs: For close-quarters hog hunting, the MRO's speed shines. Putting the red dot on a charging hog is much faster than using magnified optics.

Capable for mid-range: While the .308 stretches its legs further, the MRO is still accurate for mid-range shots with proper holdovers.

Disadvantages to Consider:

Reticle Size: The 2 MOA dot might be a bit large for some shooters who prefer a more precise aiming point, especially at distance.

Battery Life: While the battery lasts a long time, it doesn't have the illuminated reticle lifespan of some competitors. Make sure you have spares on hand.

Price: Trijicon sights are known for their premium price tag, and the MRO is no different.

My Experience:

Overall, I love the MRO on my .308. It's fast, tough, and lets me keep both eyes open for maximum awareness. If you prioritize quick target acquisition for close to mid-range shooting, the MRO is fantastic. However, if you need a super precise reticle for long-range target work, you might want to consider a magnified optic.

Online, users seem to agree with my assessment. Praises go for the MRO's durability, clarity, and speed. Some long-range shooters mention preferring a smaller MOA dot, and a few users have reported issues with the battery life, although Trijicon's customer service gets high marks for resolving those issues.

Sig Sauer ROMEO5

⁠

I wasn't sure a red dot sight was the way to go for my .308. Long-range precision is kind of the whole point of that caliber, right? But after looking at options and getting some range time with the Sig Sauer ROMEO5, I'm a believer for certain situations.

Here's what I love about it:

Fast Target Acquisition: This is the biggest win. Slapping steel at close to medium range feels effortless. The red dot is crisp and easy to pick up, letting me focus on lining up the shot instead of fussing with magnified reticles.

Surprisingly Clear Glass: Sig's SpectraCoat lives up to the hype. The sight picture is bright and clean, even in low light. It's not scope quality, but it holds its own.

Battery Life Champ: I haven't even come close to running the battery down yet. Sig advertises 50,000 hours on a single AA, and online reviews back that up. That's serious peace of mind.

Built Like a Tank: This thing feels solid. It's taken a few bumps on the range and shrugged them off. Recoil on the .308 doesn't seem to faze it one bit.

Now, for the drawbacks:

Limited Magnification: Duh, it's a red dot. Forget about those long-distance laser shots you might dream about with a .308. This sight shines at closer quarters.

Not the Most Precise Reticle: The 2 MOA dot isn't exactly ideal for pinpoint accuracy. It's great for quick acquisition, but for real tack-driving, you'll probably want a scope.

Overall, my experience has been positive. The ROMEO5 is a great choice for turning my .308 into a fast, close-range tackler. It's perfect for home defense or quick pig hunts in heavy brush. However, if you're set on stretching the legs of that .308 out to long range, this probably isn't your best bet.

What do other folks think? Online reviews are generally great. People love the durability, battery life, and the price tag. A few folks wished for a wider variety of reticle options, but overall, there's a lot of satisfaction out there for the ROMEO5.

Holosun 510C

⁠

⁠

Let's talk about the Holosun 510C red dot sight. As a .308 enthusiast, I was initially skeptical about its suitability for this caliber. However, after running a few hundred rounds through it, I'm pleasantly surprised. Here's the breakdown:

Best Features & Advantages:

Clear and crisp red dot reticle: Makes target acquisition on the .308 a breeze, especially at mid-range.

Shake Awake: Saves battery and keeps the sight powered up when I shoulder the rifle.

Multiple Reticle Choices: From simple dots to circle-dot combos, I found the option to switch reticles a big plus.

Solar Backup: Even with the shake awake, the solar panel offers peace of mind on extended outings. No more scrambling for batteries mid-session.

Durability: This sight feels tough as nails. It's taken a few bumps on the range and shrugged them off.

Disadvantages & My Experience:

Open emitter: While it offers a wider field of view, some folks might prefer a closed emitter for .308 due to potential debris concerns. Thankfully, the Holosun seems well-sealed, and I haven't had any issues yet.

Battery compartment location: Changing the battery requires removing the sight mount. A minor annoyance, but not a deal-breaker.

Overall, the Holosun 510C has exceeded my expectations for a .308 red dot. It's fast, accurate, and built to last.

Online reviews seem to mirror my experience. Many users praise the 510C's clarity, durability, and feature set for the price point. Some folks, particularly those using it for long-range shooting, do wish for a closed emitter option.

If you're looking for a versatile red dot that can handle the punch of a .308, the Holosun 510C is definitely worth considering.

Vortex Strike Eagle

My .308 is for long-range target shooting. A red dot sight is ideal for quick close-up engagements, not the kind of precision I need. The Strike Eagle, with its variable magnification, seems built for a more versatile AR-platform rifle.

Great Features, Wrong Application

Don't get me wrong, the Strike Eagle has some awesome features:

1-8x Zoom: Perfect for going from close-quarters to mid-range, but overkill for a dedicated long-range rifle.

Durability: Vortex is known for rock-solid construction, and the Strike Eagle seems built to last.

Warranty: Their lifetime, no-questions-asked warranty is unbeatable.

Here's the Rub

The Strike Eagle's extra weight and bulk slow down my .308. While the magnification is great for some rifles, it's unnecessary for long-range target shooting. I swapped it out for a higher-powered, fixed magnification scope for better accuracy at distance.

Looking online, reviews are mixed. Some AR-15 users love the Strike Eagle's versatility, but long-range shooters seem to agree: it's a better fit for other platforms. There are even discussions about users replacing the Strike Eagle with higher-powered optics on their .308s, mirroring my experience.

The Strike Eagle is a solid optic, but for my .308, it's a mismatch. Do your research and pick the right tool for the job. If you're looking for a red dot sight for close-quarters with a .308, Vortex offers other options that might be a better fit.

How to Choose The Right Red Dot for .308 Rifle?

Intended Use:

Target Acquisition: Red dots excel at close- to mid-range shooting where fast target acquisition is key. This makes them ideal for home defense, competition shooting, and hunting in brushy areas.

Long-Range Shooting: While some red dots can handle mid-range shots, the .308 caliber is capable of much more. If long-range precision is your goal, a magnified scope is better suited.

Dot Size:

MOA (Minute of Angle): Red dot size is measured in Minutes of Angle (MOA), which corresponds to how much real-world space the dot covers at a given distance.

Precision vs Speed: A smaller dot (2-3 MOA) offers more precise aiming for smaller targets, while a larger dot (4-5 MOA) is faster to pick up for close-quarters shooting.

Durability and Recoil:

.308 rifles produce recoil. Choose a red dot sight with a reputation for ruggedness and recoil resistance. Look for models with aircraft-grade aluminum construction and a proven track record for reliability.

Other Features:

Adjustability: The ability to adjust the red dot's brightness for different lighting conditions is crucial. Night vision compatibility might be relevant depending on your use case.

Mount: Ensure the red dot sight has a compatible mount for your specific rifle platform (AR-10 style, traditional bolt action, etc.)

Brands: Well-respected red dot sights for rifles include Aimpoint, Trijicon, EOTech, and Holosun.

FAQs about .308 Red Dot

Is a red dot a good sight for a .308?

Red dots can be effective on a .308 rifle, but their ideal range is for close to medium distances. The .308 excels at longer ranges where magnification becomes more beneficial for precise shot placement.

Here's a breakdown of the pros and cons:

Pros:

Faster target acquisition at close range

Lightweight and unobtrusive

Good for quick shooting scenarios

Cons:

Limited effectiveness at long distances due to lack of magnification

Can you hit 500 yards with a red dot on a .308?

Technically, yes, but it's a challenging shot. The .308 is capable of much further distances, and a red dot's lack of magnification makes precise aiming difficult at 500 yards.

What are some alternatives to a red dot for a .308?

Low Power Variable Optic (LPVO): Offers magnification for longer range while retaining some close-range usability.

Traditional Scopes: Provide high magnification for long-distance precision shooting.

What factors should I consider when choosing a sight for my .308?

Intended use: Hunting, target shooting, tactical applications? Each has different range requirements.

Barrel length: Shorter barrels may benefit more from a red dot's compact size.

Your personal preference: How much magnification do you need, and how quickly do you need to acquire targets?

Conclusion

In conclusion, selecting the ideal red dot for your .308 rifle hinges on understanding how you'll primarily use the firearm. Consider factors like shooting distance, target acquisition speed, and overall weight of the rifle with the optic attached. With a clear understanding of your priorities, you can make an informed decision that optimizes your .308's potential for your specific needs.
