Buying Guide: What to Look For in the Best AR-10 Scope Mounts
Choosing the right scope mount for your AR-10 isn’t just about holding your optic; it’s about building a reliable foundation for your entire shooting system. I’ve mounted, shot, and tested dozens, and the differences between a good mount and a great one are massive. Your AR-10 generates significant recoil, so your mount needs to be a tank. Forget flimsy components; you need something that will hold zero through hundreds of rounds and harsh conditions.
The first thing I look at is the material. Aerospace-grade 7075-T6 aluminum is the gold standard. It’s significantly stronger than the more common 6061 aluminum you find on budget accessories. It can handle the .308 Winchester/7.62x51mm recoil impulse without flexing, which is the key to maintaining your zero. Next, consider the mounting system. The American National Standards Institute (ANSI) Picatinny rail (MIL-STD-1913) is the most common and reliable. Ensure the mount’s clamping system has strong, quality screws that bite down securely on the rail. I prefer mounts that use multiple cross-bolts for a more even and robust clamping force.
Height and eye relief are critical for comfort and performance. I typically recommend a one-piece mount with a lower 1/3 co-witness height for most AR-10 applications using standard scopes. This gives you a good cheek weld without having to crane your neck. If you’re running a large 50mm or 56mm objective lens, you might need a higher mount to clear the barrel. Always consider your scope’s eye relief specification and choose a mount that lets you position the scope correctly for your natural shooting stance.
Finally, don’t overlook the finish. A hard-anodized coating is essential for durability and corrosion resistance. It protects the aluminum from the elements and from getting scratched up during use. Weight is a factor, but on an AR-10, which isn’t a lightweight platform to begin with, I prioritize strength over saving a few ounces. A well-made, one-piece mount also adds rigidity to your receiver, which can theoretically contribute to accuracy. When you’re looking for the 10 Best AR-10 Scope Mounts in 2025 – Tried and Tested, focusing on these core aspects—material, clamping force, height, and finish—will steer you toward a product you can trust with your rifle and your ammo.
Frequently Asked Questions
What height scope mount should I use on my AR-10?
This is one of the most common questions I get. The answer depends on your scope and your preferred head position. For most hunters and precision shooters using a traditional rifle scope, a “standard” height (around 1.1 to 1.3 inches from the top of the rail to the center of the scope tube) works well. If you have a large objective bell (like 50mm), you’ll likely need a “high” mount to ensure proper clearance. The best way is to get behind the rifle with the scope loosely set and see what feels natural for a consistent cheek weld.
Is a one-piece mount better than two separate rings?
For an AR-10, I almost always recommend a one-piece mount. The primary reason is the added rigidity it provides. By bridging the upper receiver, a one-piece mount can help mitigate any minor flex between the receiver and the handguard. It also makes installation much simpler, as you only have to level and torque one unit instead of aligning two separate rings. This ensures your scope is perfectly straight and reduces the chance of introducing stress into the scope tube.
How much should I spend on a good AR-10 scope mount?
You should expect to invest a meaningful amount in your mount. Think of it as an insurance policy for your often more expensive optic. A quality, durable mount from a reputable manufacturer typically falls in the $150 to $400 range. While budget options exist, they often cut corners on material (using 6061 aluminum) or have less robust clamping mechanisms, which can lead to lost zero under the heavy recoil of an AR-10. Don’t cheap out here.
What torque should I use when installing my scope mount?
Following the manufacturer’s specifications is absolutely critical. Over-tightening can crush your scope tube or strip the screws, while under-tightening will lead to a shifting zero. As a general rule, most quality mounts recommend 15-18 in/lbs for the ring screws that clamp onto the scope and 25-65 in/lbs for the base screws that attach to the Picatinny rail. Always use a calibrated inch-pound torque wrench; do not guess.
Do I need to use Loctite on the mount screws?
Yes, this is a best practice. The vibrations from an AR-10 can and will loosen screws over time. I apply a small amount of blue (medium-strength) Loctite (threadlocker 242) to the base screws that attach the mount to the Picatinny rail. Ensure the threads are clean and dry before application. Do not use red Loctite, as it is permanent and requires heat to remove. For the ultimate peace of mind with your setup for the 10 Best AR-10 Scope Mounts in 2025 – Tried and Tested, proper threadlocking is a non-negotiable step.
