Vortex Optics Razor HD Gen III 1-10×24 Riflescope
I consider the Vortex Razor HD Gen III 1-10×24 a near-perfect solution for a do-it-all AR-10. The low-end 1x magnification is truly exceptional, offering a field of view and eye box so forgiving it feels like using a red dot sight for close-quarters speed. This makes it fantastic for dynamic shooting or hunting in thick cover. Then, with a quick zoom, you have a crystal-clear 10x magnification on tap, thanks to the high-density glass, which is more than enough to make precise shots out to 600 yards and beyond on man-sized targets. The illuminated reticle is bright and daylight-visible, and the turrets have a superb tactile feel with Vortex’s fantastic VIP warranty backing it all up.
Where this scope really shines on an AR-10 is in its versatility. You aren’t sacrificing close-range capability for long-range precision. The EBR-9 reticle provides useful holdovers at higher magnifications, while the simple center dot at 1x keeps things fast. It’s built like a tank, which is necessary to handle the .308’s recoil over the long term, and the weight, while substantial, is a fair trade for the performance you get. After running this scope through drills and a hunting season, I’m convinced it’s one of the best LPVO options available for a rifle that needs to be ready for anything.

This is the optic I turn to when every single shot counts, whether in competition or from a stationary hunting blind. The glass is simply in a league of its own, providing stunning resolution and color fidelity that makes seeing mirage and trace easier. The 35x top-end magnification is massive, but it’s the usability of that magnification that counts; the image remains sharp and bright even at max power, thanks to the large 56mm objective lens. The turrets are the gold standard for tactile, repeatable adjustments.
Mounting this beast on an AR-10 transforms the rifle into a legitimate mile-capable system. The First Focal Plane (F1) reticle means your holdover markings are accurate at every magnification setting, which is critical for engaging unknown distance targets quickly. It’s built to military specifications, so the .308’s recoil is just a gentle nudge to this scope. While it’s overkill for shots inside 200 yards, its purpose is clear: to dominate the extreme long-range game. The price is high, but for the shooter who needs uncompromising performance, it’s an investment that pays dividends on target.

The eye box is a bit more forgiving than some other high-magnification LPVOs, making it easier to get on target quickly. It’s a heavy optic, but that weight is the price of its unparalleled durability. If your AR-10 is a fighting rifle or you simply want the toughest optic available, the VCOG is a top contender.
Pros
- Extremely durable one-piece construction with integrated mount
- Bright, battery-free illumination for the center dot
- Excellent 1-8x magnification range for versatility
Cons

Best Scopes for AR10 – Bigger is Better! [2025] – Marine Vetted
When you’re setting up an AR-10, you’re dealing with a platform that deserves serious glass. This isn’t a close-quarters rifle; it’s built for reaching out and making an impact at distance. That’s why my philosophy is simple: bigger is better. You want a scope that can keep up with the rifle’s potential, and that means prioritizing a larger objective lens and higher magnification. Let’s get into what to look for.
First, magnification is key. For an AR-10 chambered in .308 Win or 6.5 Creedmoor, I generally recommend starting with a scope that goes up to at least 15x or 18x. This gives you the clarity to see your target clearly at 500, 600, even 800 yards. A variable power scope in the 3-18x or 4-16x range is a fantastic sweet spot, offering flexibility for a closer shot if needed. The bigger the top-end magnification, the more precise you can be at extreme ranges.
Next, the objective lens size matters a lot. A bigger objective lens (the front lens) gathers more light. More light means a brighter, clearer image, especially during dawn, dusk, or in heavy timber. Don’t pair a powerful rifle with a tiny, dim scope. Look for an objective lens of 44mm, 50mm, or even 56mm. Yes, it sits higher on the rifle, but the optical performance gain is worth it. Just make sure you get a good set of high-rise scope rings.
Durability is non-negotiable. Your AR-10 has some kick, and the scope needs to handle it. Look for scopes that are nitrogen or argon purged to prevent internal fogging and are built with a sturdy, one-piece tube. Shockproof construction is a must. The turrets should feel crisp and positive with each click, allowing for reliable adjustments when you’re dialing for windage and elevation. A illuminated reticle is also a huge plus for low-light shooting against dark backgrounds.
Finally, consider the reticle. First Focal Plane (FFP) reticles are my strong preference for a long-range tool like this. With an FFP reticle, the reticle size changes with the magnification. This means your holdover marks are accurate at any magnification level, which is critical for rapid shooting at unknown distances. It’s a feature that truly unlocks the potential of your AR-10.
FAQ
What magnification range is best for an AR-10?
For the AR-10 platform, I think a mid to high-range variable scope is perfect. Something in the 3-18x, 4-16x, or 5-25x range gives you a huge amount of versatility. You can use the lower powers for faster target acquisition at closer ranges and crank it up to the higher end for precision work at distance. It’s all about having the right tool for the job, and a bigger magnification range means you’re ready for more situations.
Is a 50mm objective lens too big for an AR-10?
Not at all. In fact, a 50mm objective lens is a great match for the AR-10. The main advantage is light gathering. A larger lens pulls in more light, resulting in a brighter sight picture during critical times of day when light is low. The only downside is that you’ll need higher scope rings to clear the barrel, which might affect your cheek weld slightly. But for the optical clarity you gain, it’s a trade-off I’m always willing to make.
Why is First Focal Plane (FFP) important for an AR-10 scope?
First Focal Plane is important because it makes your reticle’s subtensions accurate at every magnification level. If you’re using the hash marks on your reticle to hold for wind or bullet drop, those measurements are only correct at one specific magnification on a Second Focal Plane (SFP) scope. With an FFP scope, whether you’re at 6x or 18x, your holdovers are always true. This is a massive advantage for tactical shooting or hunting where you don’t always have time to dial your scope.
What type of reticle is best for long-range shooting with an AR-10?
For long-range work, you want a reticle with clear, uncluttered hash marks for windage and elevation holds. A Mil-Dot or MOA-based Christmas tree-style reticle is excellent. These reticles provide quick reference points for moving targets, compensating for wind, and engaging at various distances without turning the turrets. Pair this with an FFP design, and you have a very effective system for getting the most out of your AR-10.
How important is waterproof and fog-proof construction?
It’s absolutely critical. A scope is a long-term investment, and if it fails because of moisture or a sudden temperature change, it’s useless. Proper sealing with O-rings and purging with an inert gas like nitrogen ensures your scope can handle rain, humidity, and the shock of recoil without fogging up internally. Don’t cut corners on this; it’s a core feature of any quality optic, especially one that’s marine vetted for tough conditions.
Can I use a hunting scope on my AR-10?
You can, but you need to be careful. Many hunting scopes are designed for lighter-recoiling rifles. The AR-10 generates significant shock, so you need a scope built to withstand it. Look for scopes that are specifically rated for magnum calibers or have a reputation for durability. The best scopes for AR10 are often labeled as tactical or long-range models, as they are overbuilt to handle the punishment and provide the features you need for precise shooting.
