Best Tactical Scope for AR 10 308 SHTF

AR-10, manufactured by Armalite, surpassed its predecessor AR-15 by offering a powerful shooting experience due to a large-sized caliber. But smooth shooting is not the only reason for making it a marksman’s favorite weapon. Several other perks, including the opportunity to customize it following one’s priority, contribute to its popularity. 

And customization is precisely where you will require a riflescope. By using a quality scope, you can enhance the capabilities of your AR-10. As the scope works to enlarge distant targets without blurring the image, you can hit precise shots during small or large hunting games or for military or law enforcement purposes. 

Nonetheless, to get the most out of your 308 rifles, you need to look for various factors and purchase the scope accordingly. Below you will find the points to examine in a riflescope. Also, we have listed down the products on which you can count for aiming impeccable shots.  

Riflescopes for AR 10 308 – Buying Guide


Your AR 10 can shoot targets at a range of around 800 to 1,000 yards. However, for having a close look at such vast distances, a riflescope is required. Hence, the higher the riflescope’s range is, the more expanded your shooting range will be. Depending upon personal choice, you can choose in between these three ranges available: 

  • Close-range Scopes: Such scopes have a range of 200 yards or less and are best for small distance hunting. You can locate and target small animals like hare or coyotes as well as birds like fowl. 
  • Medium-range Scopes: The medium range is not only hunters’ favorite but also the sweet spot for AR 10. You can enjoy sharpshooting within a range of 200 to 500 yards, along with targeting larger animals like deer. 
  • Long-range Scopes: For competitive shooting or seasoned hunters, long-range scopes with a range of around 500 to 1,200 yards are ideal.

2. Lenses Quality 

Both eyepiece and objective lens can make your sighting experience best or worst. As a quality glass secures clear vision, you should look for the one featuring ideal characteristics. Prefer buying a scope with multi-coated glass because it can adjust the brightness levels as per the surrounding light—also, the one treated with tritium grants a clear night-vision. 

Nitrogen purged and O-rings are a plus point as they prevent fogging and protect the tube from contaminating elements. 

3. Durability 

To bear the intense recoil of AR 10, a scope made of one-piece aircraft-grade aluminum is ideal. Anodized finishing and protective coating further shield the scope from internal or external damages. Along with it, you might accidentally drop your gun in water or from elevation, so it should be water and shockproof as well. 

In short, precise shots are critical when SHTF. And to deal with such situations, a scope should have the potential to work through all the beatings and rough handling. 

4. Magnification Power 

As discussed before, an AR 10 or 308 rifle has an extensive shooting range. A wide range of scope helps keep an eye on distant targets, but the magnification power governs how zoomed the prey will appear on the lens. Like scope range, there are three categories of magnification levels you can find in them: 

  • Short-Range Scope Magnification: Although you don’t need to enlarge targets at close distances, the magnification can be critical if you want to hunt small animals or birds. For such cases, the short-range scopes may offer a magnification power of 1x-4x or 1x-5x, which is enough for the purpose and cost-effectiveness.  
  • Medium-Range Scope Magnification: Normally, their magnification power is 5x to 12x and can make you hit accurate shots for up to 500 yards. Depending upon the quality of glass and detailing of the reticle, their price range varies. But they are hands down the best to prove you as a marksman in large hunting games. 
  • Long-Range Scope Magnification: Here, you can view images enlarged 12x times to as high as 25x times. And this is precisely what valorous snipers would love, as this helps them maintain a safe distance while hunting dangerous animals like bears or leopards. Nonetheless, these riflescopes with exaggerated magnification can cost a pretty penny. So, buy them only if you are going to utilize them to the fullest. 

5. Field of View 

While hunting, tracking the prey is essential but having a complete look at the surrounding area is equally critical. As it pictures a clear image in mind, better target acquisition is achieved. A scope’s field of view value indicates how many feet of area will be captured in the lens per every 100 yards. The wider the field of view, the more accurate shots you can aim to hit both stationary and moving animals. 

6. Price Range & Warranty 

The top-notch brands offer high image quality and durable construction to their customers but at an extremely high price. This may amount to investing enormous sums for either minimal or extra features you might not require. Therefore, assessing your requirements first and then seeking a befitting match is the key to follow. 

On the contrary, the problem arises when you are on a tight budget, but your shooting craze is forcing you to buy a quality scope. However, with little research, you can find some generous manufacturers that ask the least in return. But trusting them right away can amount to losing money. We recommend buying products backed by lifetime or long-term warranties to ensure you invest at the suitable scopes.

Considering that Trijicon optics have been a top priority for Marines, one can rightly estimate their products’ durable and reliable products.
