Finding the best rifle scope for your AR-10 in .308 caliber can feel overwhelming. The market is flooded with options, each boasting different features and price points. This comprehensive guide will help you navigate the complexities and choose the perfect optic for your needs, whether you're a seasoned shooter or a newcomer to the world of precision rifles. We'll cover crucial factors to consider and highlight some top contenders. This guide focuses on finding the best scope, not necessarily the cheapest.
Understanding Your Needs: Choosing the Right AR-10 .308 Rifle Scope
Before diving into specific models, let's identify your shooting style and requirements. This will significantly narrow down your options.
1. Intended Use:
-
Long-Range Shooting: If you're planning on shooting at distances exceeding 300 yards, you'll need a scope with high magnification (e.g., 6-24x or higher), a robust reticle for precise aiming, and excellent clarity. Consider scopes with features like zero-stop adjustments for repeatable zeroing.
-
Medium-Range Shooting (100-300 yards): A scope with moderate magnification (e.g., 3-9x or 4-16x) will suffice. Features like illuminated reticles can enhance low-light shooting.
-
Close-to-Medium Range Shooting (under 100 yards): A lower magnification scope (e.g., 1-4x or 1-6x) might be sufficient, prioritizing speed and target acquisition over extreme precision at longer ranges. These are often preferred for home defense or hunting applications at closer ranges.
2. Magnification:
Magnification is a key factor influencing your choice. Higher magnification allows for better precision at longer distances, but lower magnification is better for close-quarters shooting and quick target acquisition. The best magnification range depends on your intended use, as detailed above.
3. Reticle:
The reticle (the crosshairs in your scope) is crucial for accuracy. Common types include:
-
Mil-Dot: Uses milliradians for ranging and holdover adjustments. Popular among long-range shooters due to its versatility.
-
MOA (Minute of Angle): Uses minutes of angle for adjustments. Simpler to understand for some, but mil-dot offers more flexibility.
-
First Focal Plane (FFP): The reticle size scales with magnification. This is advantageous for precise ranging at different magnifications but can be more cluttered at lower magnifications.
-
Second Focal Plane (SFP): The reticle size remains constant regardless of magnification. Simpler and less cluttered at lower magnification, but ranging becomes less accurate at higher magnifications.
4. Turret Adjustments:
These allow you to adjust your point of impact. Features to look for include:
-
Zero Stop: Prevents you from accidentally turning the turrets past your zero point. Essential for long-range shooting.
-
Tactical Turrets: Provide positive clicks and are usually more robust than standard turrets.
-
Locking Turrets: Prevent accidental changes to your adjustments.
5. Eye Relief:
Eye relief is the distance between your eye and the scope's eyepiece. Insufficient eye relief can result in a bruised eye. Look for at least 3.5 inches for comfortable shooting. This is especially crucial with high-recoil rifles like the AR-10.

Choosing the Right Mounts
The scope mount is just as important as the scope itself. Ensure your mount is specifically designed for the AR-10 platform and is rated for the weight of your chosen scope. A poorly chosen or improperly installed mount can lead to zero shift and shooting inaccuracies.
Conclusion: Finding Your Perfect AR-10 .308 Scope
Selecting the best rifle scope for your AR-10 .308 requires careful consideration of your individual needs and shooting style. By considering factors such as magnification, reticle type, turret adjustments, eye relief, and your budget, you can narrow your options and choose the optic that enhances your shooting experience. Remember to always prioritize quality and reliability, especially when shooting a high-powered rifle like the AR-10.
