Key Features of an AR-15 Scope

  1. The magnification is rated from its magnification power.
  2. The field of view is rated from the distance range of shot you can attempt.
  3. The reticle color is varying based on each individual product.
  4. The clarity is rated from low to high.
  5. The setup is rated from easy to hard.


The magnification is the zoom factor of how much the picture viewed from the riflescope is enlarged. The low magnification power scope won’t provide as good of image enlargement but it is less susceptible to shaking. A higher magnification has  greater image enlargement, however it is prone to more shaking and a smaller field of view of image.

You are advised to use the least magnification power when shooting at closer ranges as you don’t need much assistance in viewing your target. Magnification comes in handy when shooting at longer ranges as the enlarged image allows you to focus on your target and aim with maximum accuracy.

Field of View

The field of view of each riflescope depends on its magnification power. For higher powered scopes, the field of view is a lot smaller compared to those with low powered scopes as their image is enlarged and only focusing on the target rather than its left and right surrounding.

In other words, field of view is the distance visible through the scope from the left to right side of the image at a distance of 100 yards. A larger field of view is ideal as the shooter can view as much of his target and surroundings as possible.


A reticle is the crosshair pattern in a circle that is overlaid on the image which shows the rifle’s position on your target. There are different type of crosshairs such as duplex crosshairs and such in which the position and type of crosshairs patterns are slightly varied. However, they serve the same purpose to assist you in aiming during hunting.

Not only that, most reticles come in their standard color, black. Nevertheless, some reticles are illuminated with red or green color which comes in handy during low light conditions as you can view the crosshairs pattern easily when aiming. You can also have a better view of your target in the dark when hunting.


The clarity of riflescope is how clear the image of target you are able to view through the lens of your scope. It depends on the lens of your scope. A lens clear from scratches and damage makes it easier for you to aim at your target.

Also, most riflescopes are filled with nitrogen gas and sealed with O-rings to prevent moisture in the scope. This is important to prevent the inside of the scope from fogging up and obstructing your view. Also, the reticle should be bright and clear so you can have a clear view of your crosshairs and your target to improve the accuracy of your shot.


The setup basically refers to how easily you can zero in your riflescope at a particular yardage. After zeroing in, it further tests on how long it can maintain the zero so you don’t have to frequently adjust the zeroing if it runs easily.

Apart from that, some riflescope comes with turrets to make precise windage and elevation adjustments for proper zeroing to improve the accuracy of your shot. These turrets can either be resettable and lockable or rapid action turrets to further improve your hunting experience.


In a nutshell, I hope my review assists you in making the right choice of rifle scope that is worth your investment. Factors such as reticle, field of view, magnification power, image clarity and setup need to be taken into consideration. Why not record your experience with the best video camera for hunting so you can share them with others? You might need a backpack to store your equipment as well.
