Main Features to consider

As a hunter, you want the best scope for your rifle. These days the ACOG scope is easier to aim and making the kill shot is simpler. Yet, there are some main features to consider when buying any of the reviewed optics here.Main Features to Consider

The Importance of the Numbers on a Scope

Before choosing a riflescope, you need to know the importance of the numbers. As an example, we will use the ACOG 1.5×15 to explain the numbers. The 1.5x means that the target you are viewing will be 1.5 times closer to the naked eye.

The last number is the objective lens diameter in millimeters and measures 15mm. When viewing the numbers as explained here, the optics classified as a fixed scope.

What Objective Lens Size do you need?

The objective lens size varies from one model to another and can start from 16 – 40mm. One needs to remember that the larger the size of the lens the harder it becomes to hold your rifle.

Trijicon ACOG Scope

Using a large lens makes the rifle uncomfortable to hold leaving it unbalanced and heavy. Another important thing is that the bigger the objective lens is the brighter the object will be that you are targeting.

Choosing the correct eye relief is important

Choosing the correct eye relief is as important as choosing the objective lens. The exit pupil is determined by holding the optic at arm’s length.When doing this the small circle of light appearing in the eyepiece is the exit pupil. While the eye relief is the distance that you can hold the ocular lens away from your eyes and still view a clear image of your target.

Length and Weight

When choosing your scope it should not be too heavy. The length of the optics normally made according to the length of the rail mounts. Choose a lightweight model that fits on your gun.

The Reticle

The reticle also known as the crosshair is the fine lines that you observe when looking through the scope. The styles of crosshairs can vary from one model to another.

If you are planning to shoot a fixed target, choose one with the correct reticle, as fine lines do get lost when viewing a target. The crosshair helps to increase your accuracy when shooting.

The Durability of the Scope

Durability is one of the main features and measured according to the material used to build the scope. Other factors to consider, especially when out hunting:

  • Shockproof
  • Waterproof
  • Fogproof
  • Warranty

We hope that we have helped you with the important features when choosing your high-quality scope, let us look at some of the ACOG scopes available in our comparison list.

Final Thoughts

We have reached the end of our Trijicon ACOG scope reviews. We hope that it helps you to understand and find a suitable one for your hunting needs.

Trijicon ACOG Scope v

If you are uncertain in choosing the best one you can consider the following: always consider the size of your weapon you want to attach the scope as a smaller weapon works well with a compact scope, always consider the cheek welds as one with a low cheek weld works best with a low-profile ACOG.

On the other hand, you can also consider the combat distance when used in close quarters as a wider field of view will help you maintain peak combat awareness and using a lighter scope gives you more maneuverability.

Consider the caliber making sure the BDC lines match when used at long distance shooting and think about the eye relief as well. Make one of these scopes an added benefit to your gear.
