Criteria for Choosing the Best Thermal Scope for AR-15

When shopping for the best thermal scope for AR-15, here are the key factors you should take into account before you settle on any product.


Just like in traditional rifle scopes, the magnification in thermal rifle scopes varies from one product to the other. Generally, the magnification power ranges from 1x to 16x for you to pick one that is best for your needs.

The magnification that you pick will largely depend on whether you are looking to use the scope for short or long-range applications. The further you plan to shoot, the higher the magnification the scope should have.

However, if you plan to use the scope for short to medium ranges up to 200 yards, go for moderate magnification power as too much magnification will be an overkill.


The resolution of a thermal scope can make or break your shooting or hunting trip. When making your selection, consider both the thermal resolution and display resolution of the scope as the two go hand in hand.

Detection Range

The next facet you should take into account is the thermal scope’s detection range. This is the maximum distance you can see a target clearly after the scope detects the body heat it produces. Some high-end thermal scope has a long detection range up to 4,000 yards which is more than sufficient for hunting, surveillance and patrol.


Thermal rifle scopes are not cheap. You will therefore want to spend a big amount of money and get a product that will last for ages. Look at the construction quality of the scope and pick one that is built to last. Also make sure that the scope you get is recoil resistant to withstand the recoil the AR-15 produces.

Refresh Rate

The next thing you should consider is the scope’s refresh rate. Refresh rate is very important especially when you are hunting fast-moving game like hogs and foxes. The best thermal scope for AR-15 comes with a refresh rate of 50Hz or more. With such a speedy refresh rate, you will have smooth image views of the target in any situation.


Try and look for the lightest thermal imaging rifle scope possible. Usually, a heavy scope is cumbersome to carry around, especially when hunting. It can also interfere with the balance of your rifle and affect is accuracy.

Weather Resistance

Lastly, look for a thermal scope that is built to be operable in all weather conditions. The lens of the scope should be protected from dust, moisture and heat to ensure unimpeded field use. Also, the scope has to be fog proof to keep the lenses clear in all environments.

How to Zero a Thermal Scope

Zeroing a thermal imaging rifle scope is almost similar to zeroing a traditional rifle scope, along with adjusting windage and elevation.

When you have bought the thermal scope, you should start to zero it in at closer distances, compared to the distance you zero in a traditional scope. Here are some easy steps to follow.

  1. Place the first shot with the aligned reticle at the middle of the target. Generally, it takes a single shot to align the reticle to a rifle, and the point of impact should be visibly clear.
  2. Adjust the reticle while being careful not to move the rifle until the reticle reaches the tip of the point of impact precisely.
  3. After that, zero it in every 50 yards until you reach an ideal range, then customize the settings to match your preference.
  4. Save the reticle position and take another shot.
  5. If the shot hits a dead center target, you have successfully zeroed your thermal scope.


  • Can you use a thermal scope during the day?

Yes. A thermal scope is safe to use during the day and in the dark as well. Though it can be tricky to use a thermal scope during the day, especially when the temperatures are high, it is still possible to find the target and get a clear shot.

  • Can you see through fog with a thermal scope?

Yes, you can see through fog with a thermal scope. A thermal scope will also help you see through other obstacles like smoke, rain, mist, snow and dust storms, not just fog.

  • How far can a thermal scope detect?

It depends on the detection range the scope is built with. For most budget thermal scopes, the detection range varies from 900 to 1,000 yards. On the other hand, the detection range in high-end thermal scope is higher with some models offering a detection range up to 4,000 yards.

  • Do I need a thermal scope for night hunting?

Yes. Thermal scopes make valuable rifle accessories when it comes to hunting nocturnal game such as coyotes, hogs, foxes and other predators. They provide impeccable target acquisition in the dark and also help increase your situational awareness.


A thermal scope that is well made will help you find and acquire targets with ease in typical nighttime environments. All the scopes we have mentioned above are perfect for use the AR-15 rifles. Examine your hunting habits, needs and your rifle’s specifications, then pick the scope that works best for you.
