AR-15 Scope Buying Guide


In purchasing a scope, you must be wise. Usually, a more expensive scope is better. The materials used are better and the performance is generally unparalleled. However, if you can’t afford an expensive scope, you can always get the best one from the price range you have in mind. Remember that your AR-15 scope should be lightweight, too. It’s impractical to have a heavy scope with your AR-15, which is designed to be a compact rifle, because it will slow down your hand movement and it won’t improve handling. Also check the durability of the scope through reading available reviews.

If you’re going to use a scope for tactical use or close range shooting, remember that it should have a fast target acquisition feature. Red-dot sights and holographic sights are usually the choice for this type of shooting. If you’re going to shoot at long ranges, you don’t have to look for the fast target acquisition feature, instead, look for one with a moderate magnification. It’s also unreasonable to purchase a scope that can outrange the ammo you’re shooting. Opt for the scope that can work at the optimum range you’ll shoot; get the scope you’ll actually use.

There is a lot of factors to consider but before I tell you what to specifically look for in a scope, be knowledgeable of the parts of the AR-15 first.

Parts of an AR-15 Scope

  1. Elevation – This turret provides vertical adjustment for your reticle. The adjustments are measured either in MOA (Minute of Angle) or MRAD (milliradian).
  2. Focus – These dials on the eyepiece allow you to adjust the focus of the reticle to provide the sharpest level of clarity possible as you view your target.
  3. Illumination – It provides lighting for your reticle and helps you aim in low light situations and shadow areas.
  4. Magnification – Sometimes referred to as the Power Ring, this allows you to adjust the magnification power of your scope depending on its specifications. By dialing the magnification up and down, the shooter can zoom in and out on their target.
  5. Objective lens – This is the lens on the other end of the scope that gathers light around the target. Their diameter is measured in millimeters. The objective bell is the housing for the objective lens. Some bells hold up to 75mm of lens or more.
  6. Ocular lens – This is the piece of glass the shooter faces when he aims. It is generally smaller than the objective lens and it focuses the light gather by the objective lens into the eye of the viewer.
  7. Parallax – It is the term that describes the difference in angles between objects that are seen up close and those seen far away.
  8. Windage – The windage turret allows you to adjust the horizontal alignment of your reticle. Adjustments are also measured in MOA or MRAD like the elevation turret.

Tips on How to Choose the Best AR-15 Scope

Below are the things to consider when selecting the best AR-15 Scope for your needs.

  1. Purpose
  • If you’re shooting at 100 yard targets, a fixed scope of 6x magnification will do. It’s smaller and lighter. It is also less expensive than the variable powered scope.
  • If you’re into competitions, you’ll need a scope that will help you acquire targets in a blink of an eye. For closer ranges, 1x will do. For distances beyond 100 meters, opt for a scope with a magnification power of 1-6x.
  • If you’re a sniper, you’ll need a high powered scope with premium quality. This is because most of your targets will be at 600 meters or farther.
  • If you’re a hunter, a scope with 3-9x magnification is ideal. If you wish to shoot from dawn to dusk, consider larger objective lenses and illuminated reticles.
  • If you’re a soldier, you would want a durable and dependable scope with 1x for short ranges, and a medium-to-long variable scope for long range.
  1. Objective Lens
  • A larger objective lens gathers more light.
  • This is beneficial in low light situations and will help you identify the target faster.
  • However, a larger objective lens means you also get a heavier and lighter scope.
  1. Magnification Power
  • The lower the magnification, the wider the field of view, and the easier it is to acquire your target.
  • Higher magnification allows you to watch your target which is farther away and will be helpful to you when you are observing your target.
  • A variable power scope offers both options but it’s more complicated than the fixed scope because it is heavier and more expensive.
  • If you’re a plinker, a scope with 3-9x magnification power will do.
  • If you’re into hunting, it’s recommended that you get a lower powered scope to find targets faster.
  • If you’re into competition shooting with stationary targets, it’s best to get a higher powered scope. A 4-20x magnification power is usually the ideal choice for competitors.
  1. Eye Relief
  • Eye relief is the distance between your eye to the ocular lens to make the scope’s image focus at the back of your eye.
  • Modern scopes usually have the 2-4-inch range.
  • The picture will perfectly fill the eyepiece if you’re following the correct distance of a scope.
  • When you’re too close, the image will fill only a part of the eyepiece.
  • You’ll know your eyes are too far if the eyepiece will show only a part of the image.
  1. Weight
  • If you’re usually hunting from place to place and you love going on long hunting journeys, you have to consider the weight of the scope.
  • You’ll be carrying your rifle a lot as you travel which makes it heavier and heavier as the trek continues.
  • Avoid regret by purchasing that 3lb. scope if there’s an available scope with the same specifications weighing 1 pound.
  1. Turrets
  • Consider the quality of the turrets because they help you in sighting in and properly adjusting the scope in hitting targets at whatever distance you choose.
  • Each Minute of Angle (MOA) is divided into 60 seconds.
  • One MOA is equal to about one inch at a range of 100 yards.
  • The turrets will usually have positive detents, either 1/4 or 1/8 MOA.
  • At 100 yards, the increments would either be ¼ inch or 1/8-inch adjustment.
  • At 400 yards, it’s either 1 or ½ inch.
  • Most turrets will allow you to reset the dials to zero after dialing it in.


You’ve probably noticed that there are several things to consider before purchasing your AR-15 scope. And a lot of reading will help especially if you’re a first-time buyer. One of the most important things to take note is the type of reticle because some reticles are better suited for close range use while others are ideal for long range shooting.

Also remember that your AR-15 should get a scope that can take the two-way recoil. It’s always advantageous to get a scope mount that has a positive recoil stop to prevent slips. Don’t settle for a clamping mount because it won’t hold up to sustained recoil.

Mind the price and the quality of the AR-15 scope as well. Not all expensive scopes perform well and not all cheap scopes are of low quality. You have to read customers’ reviews and study the scopes’ specifications. If you can’t maximize the performance of the scope because your activity hinders you from doing so, then it’s close to being useless. It’s significant to get a scope that you can use for your specific activity.

The technology of AR-15 scopes has been developed at a rapid rate throughout the recent years. Scopes now offer more practical features. Clearly, there are a lot of AR-15 scopes to choose from but with proper knowledge, knowing which scope to get becomes easier. With several prices and brands to choose from, it may look confusing. But hopefully, through this guide, I have made it easier for you to decide.
