Best AR-15 Scope Platforms and Uses:

What is your planned use for your AR-15 rifle?

AR-15 is a platform that can come in a variety of calibers. The planned use of the rifle will determine the caliber and the desirable optics. Will the AR-15 be used for home protection, competition shooting, hunting, or plinking at targets? Knowing the nature of the target and having a basic idea of how far the target will be, will give you a better idea of what will be the best AR-15 scope to purchase.

Best AR-15 scope Close range: 0 to 100 yards

The best scope for AR-15 firearms used at close range is a red dot sight. A red dot sight is usually best for home defense, self-defense, close-range competitions, and close-range hunting. They are 1x without magnification, so they can be used for distances passed 100 yards, but are not as precise. A magnifier accessory can be added for an additional cost. The shooter has to rely on the strength of their own eyesight to focus on the target. The illuminated reticle aids in quick target acquisition.

Best AR-15 Scope Close to medium range: 0 to 300 yards:

Hunting and some competition shooting will require a magnified scope that will help with target acquisition at 0 to 300 yards. A good example of this is the hunter in the tree stand that needs a scope that can be turned down to 1x magnification to see the deer as it walks under the tree. That same hunter might need to turn up the magnification to see a deer, as it enters the field on the opposite side from where the tree stand is. Magnification can assist a hunter to adjust the clarity of the scope for their own eyesight. The best scope for AR-15 firearms used at close to medium range will need to be lightweight, easy to maneuver and have fast target acquisition.

Best AR-15 Scope Medium to long range:

Medium to long range scopes will be used for distances from 300 to 600 yards or more. They require a higher choice of magnification. Even at the lowest setting, they are still magnified, which is why they are not preferable at close ranges. The objective will be larger, in order to control the amount of light transmitted thru the scope and will result in a wider field of view. This allows the shooter to be able to see the target even when fully magnified. The larger objective can make these scopes slightly heavier. These scopes are often used in long-range shooting competitions or shooting that deer or elk at 500 to 600 yards.

What are the Ar-15 scope specifications?

Magnification and objective lens specification

In order to decide which is the best AR-15 scope, you need to understand the specification numbers for the scope. For example, it may read 1x9x20. The first two numbers refer to the magnification. In this case, the scope will be a zero magnification at 1. The second number indicates that the scope is adjustable from 2 to 9 magnification. The last number is the size of the objective lens in mm. The objective is the end of the scope that is opposite of the eyepiece. A larger objective lens allows for more light to enter the scope. If you hunt in low light conditions you may want a larger objective lens.

Parallax adjustment for the reticle: MOA vs. Mil-Dot

There are also specifications for precise windage and elevation adjustments. This is also called the parallax adjustment of the reticle. These maybe MOA (Minute-of-Angle) or Mil-dot.

MOA = Minute-of-Angle:

A scope with MOA adjustment has a 1-inch adjustment at 100 yards. You can adjust the impact over, up, or down 1 inch for each full MOA adjustment. Most scopes will have the MOA divided into smaller hash marks for more precise adjustment. Larger MOA adjustments will affect how much target is covered. For example, 3 MOA would cover 3″ at 100 yards, 6″ at 200 yards, and 9″ at 300 yards.

Mil-Dot adjustment:

Mil-Dot adjustments are typically used for shooting at ranges where the target is measured in meters. They can be difficult for those who aren’t super familiar with the metric system. These are a good choice for the target shooter that wants a lot of versatility for precise shooting.

What type of reticle do you prefer?

Best AR-15 Scope Reticle

The reticle is the image you see when you look down the scope. Traditionally they are called cross hairs because for generations that is all that was available. Now there are 4 basic types of reticles to choose from. This is constantly changing as scope manufactures listen to their customers and try to improve their products in a very competitive market. The choice of reticle you will need for your AR-15 scope will come down to personal preference and use of the firearm.

Duplex reticle:

Duplex reticles have a vertical line that crosses the center of the horizontal line just like traditional cross hairs. But these reticles take this one step farther by having thicker lines at the sides and thinner lines in the middle. They need to be sighted in at 100 yards and manually adjusted for bullet drop and windage. They do NOT have any marking for the bullet drop and windage like some reticles have. These types of reticles are good for smaller calibers and situations where you want some magnification. These are common reticles on rifles used in hunting at medium ranges.

BDC = bullet drop compensating reticle:

BDC reticles have hash tag lines below the center of the crosshairs. First, the scope needs to be zeroed in at 100 yards at the center of the crosshairs. Then each line below represents an additional 100 yards. They are excellent for long range hunting and 3-gun competitions. The one drawback is that they are typically designated to a specific caliber and ammo speed. If you need to buy different ammo, because your supplier doesn’t carry that one anymore, you will possibly need to get a different scope altogether.

EBR Reticles:

EBR-1 reticle:

This type of reticle is similar to the BDC reticle with one big difference. The lines on the reticle match adjustments on the turrets for elevation and windage. When you make adjustments to zero in the scope the lines in the reticle also adjust. This allows for you to be able to adjust the scope for any caliber and ammo speed.

EBR-2 and EBR-7 reticles:

These types of reticles are the same as the EBR-1 but add dots to either side of the center line to allow for windage. The best EBR reticle for your AR-15 scope comes down to personal preference.

Red dot sight:

A red dot sight is very handy for close range shooting, such as home defense or close target competition. They have very little to no magnification depending on the sight. There are magnifier accessories that can be added for an additional cost. Both eyes are used to acquire your target, unlike a traditional scope, where you close one eye and focus with the other. The red dot is illuminated for quick and easy target acquisition.

Best AR-15 Scope Lens Coatings:

The coating on a scope refers to the lens coating. It is used to reduce light loss and reduce glare. Lens Coating is also designed to help make the lenses scratch resistant. Quality AR-15 Scopes will have o-rings sealing the tubes and will be charged with an inert gas , such as Argon to remove any debris or dust particles from contaminating or fogging up the internal surfaces of the glass.

The quality of the coating depends on the glass quality and coating applications. Here is where spending a little more for the best AR-15 scope will be worth the money. The following is a simple explanation of coating specifications.

  • Coated – single layer on at least one lens surface on the scope
  • Fully Coated – single layer on all glass surfaces exposed to air
  • Multicoated – multiple layers on at least one lens surface
  • Fully multicoated – multiple layers on all air to glass surfaces

Best AR-15 Scope and Your budget:

For most of us, the most important question when purchasing the best scope for AR-15 firearms is our budget. Scopes come in several different configurations and price ranges from as low as sixty dollars to as high as a couple of thousand dollars. We have done the serious legwork for you.
