Frankly, the scope doesn’t come with any extraordinary features but still, we consider it as one of the good scopes because of its thought-out construction. For example, the company has added ACSS Orion reticle in the scope to enable quick-ranging and wind holds for fast target acquisition. Besides, whether you are hunting or in a dangerous situation, the built-in BDC in the reticle will ensure the most accurate shots possible.

Moreover, the reticle has been placed in the first focal panel to help the reticle adjust its size when you change the magnification from 4x to 14x. However, it is not an illuminated reticle, so you will not have a clear image in the low light.

The scope can also provide clear and parallax-free views to shoot from long distances. But if you ever have a parallax problem, don’t worry, it has a parallax knob for adjustment. Additionally, the scope is designed to be durable and resistant to fog, water, and shock.

Leupold has gone minimal while selecting the reticle for the scope, they have used classic Duplex reticle so that the scope can be mounted on any long-range precision rifle. The scope is located in the second focal panel, hence, even if you change the magnification, the size of the reticle remains the same.

What we liked about the scope is its lens! The company didn’t stop just by adding multiple layers of coating, they have also included the Twilight Light Management System in the lens. So, what happened is, that the lenses now not only have the ability to reduce color aberrations but also have the increased amount of visibility to use the scope in the low light.

Does the reticle of the scope have low light visibility?

The reticle of the scope has been made by using the Twilight Light Management System which helps the reticle to have clear visibility in the low-light situations. Therefore, even though the scope doesn’t have an illuminated reticle, you can still acquire easy targets in the low lights.

Buying Guide Of Tactical Scope For AR-10 308 SHTF

Since the AR-10 308 is a military-grade spec, it is obvious that you will require tactical-specific scopes. In long-range shooting, you will need rugged and flexible scopes for more precise shots. But these features are not enough, there are other important factors to consider before you buy the scopes for your rifles, such as:

Glass Quality

Just having a variety of ranges in magnification and lens diameters, doesn’t ensure the optimum performance of the scopes. Especially if you’re using military specs like AR-10, the glass must have the ability to transfer sufficient light for bright images.

Hence, while buying the product, check whether the glasses have full multi-coatings or multi-coatings to ensure enough light transmission in the scope.


It doesn’t matter where you use the AR 10 308 rifle, the scopes must be made of high-quality material such as 7075-T6 Aircraft Aluminum Alloy.

Otherwise, there will be a high risk for the scopes to get damaged in an intense or bumpy situation. Besides, who likes to see hard-earned money go to waste because of poor-quality products, right?


It is another important factor to consider while buying the scopes. The internal components used in the part can make it quite heavy to mount on the rifle. So, it would be better if possible to try to find a lightweight scope or at least not too much heavy scope for a 308 rifle.


When you are looking for scopes for long-distance precision rifles, you should ensure the range of magnification of the products. Whatever scope you choose, if it’s for long-range rifles the magnification power should be from mid-high range.

Turret Adjustment

Two common types of measurement units are used to adjust the elevation and the windage. One is the MOA system, if a scope has MOA system, it means the turrets will be measured as a minute of angle.

On the other hand, there is the MIL or the Milliradians system; some scopes come with this measurement unit to adjust the turrets. Both of the units are easy to use, it mainly depends on your preference for which one you feel comfortable using.


For long-range rifles, you can choose a mil-dot reticle or a BDC reticle. Both work fine with the AR-10 types of rifles. However, it is better if the scope comes with an illuminated reticle so that you can also use the scope in low-light situations.


The reticles can be placed either in the first focal panel or in the second panel. If the scope reticle is in the FFP, your reticle size will increase along with the increased range of the magnification. So, it is a very helpful feature for long-distance rifles as it gives more flexibility to aim at different ranges.

Unlike the second focal panel, where the reticle size doesn’t change with the magnification range. Hence, you don’t get an equal amount of flexibility with this panel scope.

Objective Lens

It is a place through which the light enters the scope. Hence, the larger diameter objective lens is very important for long-range shooting rifles because it mainly determines the level of bright and clear image you will get with the scope.

Eye Relief

There should be a minimum level of eye relief in high-power rifles like AR 10. It will ensure that your eyes don’t get injured in heavy recoil situations.


To sum up, in the SHTF-type situation, you will need a high-quality scope for a clear image of the target and also to have a precise shooting range with it. When you are using AR-10 308 military specs for this purpose, you should look for tactical scopes that are compatible with this rifle.

The reviewed products will come as a great aid to finding compatible scopes for any military specs. If you are a long-range precision target practitioner or hunter, these scopes will also be helpful for you. Lastly, we recommend you to use the given checklist while purchasing the scopes, this will ensure whether the scopes will be a right fit for the rifle according to your needs and preferences.
