best scope for 223Nikons are a tried and true company when it comes to firearm scopes. And given that this Nikon was designed specifically with the .223 rem round in mind (hence the name), it’s no surprise that this is one of the most popular scopes on the list for this type of round.

The BDC reticle uses ¼ MOA adjustments and can go farther than 600 yards while maintaining precision.

While being a more affordable option, this scope is a great value for the money and is incredibly feature packed. The Nikon ProStaff’s zero-reset turrets make field adjustments simple and quick with its spring-loaded adjustment knob. The multi-coated optical system which is usually only found on more expensive optics, allows for up to 98% of light transmission. This helps make for a brighter and clearer image.   

Like the Nikon p223, this optic also has the BDC reticle technology. The BDC makes long range shooting a breeze but does not have an illuminating option for those seeking to use this after nightfall. This optic has the shortest magnification capabilities, so it may not be suited for the longest-range shots. It is also worth noting that the ProStaff 3-9 x 40 is also waterproof, fog proof, and shockproof making it extremely durable and long lasting for the price. But not to worry, although this has a rugged build this is still going to be one of the least heavy options of the bunch given that it is made of lightweight aluminum.

What to consider when buying the a Scope for your 223

Your experience level

Something to think about when buying a new scope is how much experience you have with scopes and firearms. If you’re new to using scopes you may want a simple scope at a lower cost. On the other hand, you may also want something with more customizable options if you are a more experienced shooter.

Mounting options

One more thing to consider about your scope is how you plan to mount it to your firearm. Mounting your scope to your firearm properly will allow you to use the combo in a safe way while being assured your scope stays in place and does not get damaged. There are a few options you have when mounting your optic to your firearm. Before you can choose which way to go you must know whether you plan to mount your scope to one single firearm or not.

If you do plan to keep your scope on a single firearm you are going to want a fixed mount. If you’re using a fixed mount you have two types of mounting options:

  • Universal scope mount
  • Dovetail scope mount

If you do not plan to use a fixed mount here are a few options that could work:

  • Weaver style mount
  • Picatinny style mount
  • Clamp-on mount

The anatomy of a scope

How a scope works is a little more complicated than why you might want one. A scope is made up of five main parts: the objective lens, the tube, the eyepiece and ocular lens, and the turrets.

The scope will start out with the eyepiece which is what holds the ocular lens in place. Next is the power ring which you can use to adjust the magnification of the scope. You also have a scope tube which is the long metal piece that connects the eyepiece and ocular lens.

On top of the tube is the turrets. These pieces are used to adjust the windage and elevation in MOA or MIL. There may also be a parallax error adjustment in this area. Not all rifle scopes have this feature since this is only needed for long range shooting. After this is the wider area called the objective bell. This is the part of the scope that holds the objective lens in place. As you may have guessed, the next part is the objective lens. As mentioned there are lots of parts that go into a scope but the most important part you will find are the lenses.

The largest lens is the objective lens which is what transmits light to the ocular lens, the lens that the shooter faces. This lens is usually made to be fog proof and water proof for obvious reasons.

Why you need a scope

You need a scope on your firearm for the simple reason of life being so much simpler when you have one. No one is able to have perfect aim and precision with just their naked eye and a firearm as much as we would like to believe we could. If you are doing any type of long range shooting a riflescope is one hundred percent necessary. A scope is also great for a lot of short-range shooting as well but with long-range shooting there is just no question. Without a scope you can expect your shots to be sloppy, unreliable, and unpredictable, while a shot with a scope becomes laser-focused, repeatable, and dependable.

What to consider and breaking down the specs

Before deciding which scope is best for .223 you must consider some information to make an informed decision. There are a lot of components that go into buying a scope and if you aren’t sure about what the terms mean and how they affect the quality of the scope this can be a confusing process. Let’s break down the specifications you might see on each of the scopes and why they matter.


Your reticle is the little crosshairs you see inside your lens when you go to use your scope. There are lot of types of reticles out there and which one you use is up to personal preference. Three popular reticle types are mildot and BDC.

BDC reticle: A BDC or bullet drop compensating reticle is a modified crosshair that uses markings under the middle of the crosshair to predict bullet drop over long range.

Mildot reticle: The name mildot comes from the term MIL or milradian. A mildot reticle uses milradian dots on the crosshair for measurement and allows the shooter to find the approximate distance of their target.

Illuminated reticle: An illuminated reticle uses light to brighten the reticle in order to be able to see in low lighting conditions.

Dot reticle: This type of reticle simply uses a red dot in the middle of the reticle to aid in aiming.


MOA (stand for minute of angle) and MIL (stands for milradian) are types of measurements used when adjusting your scope’s turret. This is also a personal preference. While most scopes used to use MOA trends are now pointing towards MIL.

Ease of use

The ease of use in your optic will be something that will drastically improve your user experience. There is a lot of technology out there these days that will help your rifle scope be easier to use and can help you save time and effort. A few features that aid in this may be a fast focus eyepiece, zero-reset turrets, and illuminating reticles.


The glass used for your optic is going to be what makes or breaks the image you receive when looking through your scope. High quality glass will enhance the image’s sharpness, color, and contrast. It will also likely be multi-coated allowing for more light as well as fog-proof so that you are able to utilize it in any condition.

Tube size

Your tube size is going to affect how wide your field of view is. If you size up in the tube size, you will also get a wider field of view. This can also affect how heavy your optic turns out because your tube is one of the main factors that contributes to its weight. Some people believe that a bigger tube size will contribute to the scope transmitting more light but that is actually not the case. The size of your tube does not usually make a huge difference in the overall quality of your optic, so it is not something you should put much weight on.

Eye relief

Eye relief is the space between the shooters eye and the scope in which they can still fully see and utilize the picture. The farther away that a shooter can be from the scope while still being able to see everything clearly, the better. This helps with where you can mount a scope to your firearm, how comfortably you’ll be able to hold it, and the safety of your scope. Eye relief helps with safety because you want to have your face as far away from your firearm as possible so that you don’t get hit due to recoil.

Objective lens size

Your objective lens size dictates how much light you’re able to bring in, in this case typically bigger is better. But as expected, bigger also normally means more expensive and a bigger lens size means that your scope may end up being on the heavier side which is not ideal.


The brand of an optic may be something you want to heavily consider. Like any other products on the market, there will be optics by brands that are more reputable than others. Certain brands have been around for a long time and have a history of producing high quality optics. Another thing to consider is the warranty and customer service that the brand provides so that you know you are in good hands should anything ever go wrong with your scope.


While price may be a determining factor when making most scope purchases, the majority of scopes made for .223 rounds are fairly inexpensive. Still, depending on your circumstances price may be a deciding factor for you. If you are a more experienced shooter you may find that a more expensive and complex optic may be up your alley. Likewise, if you are just starting out you may not want to make such a large investment upfront.

Size and weight

The weight of your scope may matter to you if you believe that you will be carrying your firearm around for long periods of time. If you think that you only will be using your firearm every now and again and for short time periods, this may not be important to you.

Low light capabilities

Depending on how you plan on using your firearm, purchasing a scope that performs well in low lighting conditions may be in your best interest. Usually if you are hunting during evening hours you will need a scope with an illuminated reticle option so that you can still clearly see through your scope and use your crosshairs as intended.


Accuracy is likely going to be the most important factor to consider when buying a scope for your AR-15. A scope is nothing if not accurate as the whole reason you are purchasing a scope to begin with is to improve long range precision and dependability. When choosing a scope for your .223 you’re going to want to try to find the optic with the most accuracy possible that way you can take the guess work out of shooting and improve your performance.


The ruggedness of a scope is similar to its durability. This has to do with whether or not it is weather proof, fog-proof, or shock proof, and another factor of this is the material it is built out of. A shooter would want his or her scope to be as rugged as possible so that they get their money’s worth out of their scope. The more rugged an optic is, the longer it is likely to last.


The clarity levels of a riflescope are incredibly important because this affects how well you will be able to use the scope overall. If the scope is not clear, the reticle becomes useless and none of the other features of your scope matter. Without clarity a scope is not very useful at all and the addition to your firearm will not improve your performance.


The magnification capabilities of your scope matter especially when shooting in long-range scenarios. How well a scope can zoom and magnify on a desired target will determine how much accuracy a shooter will have at far distances. When the magnification capabilities are higher, the shooter will be able to shoot farther with more repeatable and dependable precision.

First or second focal plane

Whether your reticle is in first or second focal plane is again, personal preference but something you may need to consider. When your reticle is in first focal plane (FFP) you will notice that your reticle will change sizes as you zoom in order to keep up with the magnification. On the other hand, a reticle in the second focal plane (SFP) will remain a constant size regardless of how magnified the view is.

What is the best .223 scope for me?

When it comes to long range shooting you really can’t go wrong with using .223 rem. which is why adding the perfect scope to the duo will make your shooting experience even better. You may be thinking that these all sound like great options, but you aren’t sure which one to pick.

While any of the five choices on this list will certainly be a good match, there are many factors that will vary from person to person. If you are looking to shoot at extremely far distances you may hold the magnification capabilities high in your decision. On the other hand, if you know you’ll need to use your rifle the most during darker hours of the day, a scope’s illuminated reticle option might be more important to you.

In order to get the right scope for your needs you must consider which characteristics are the most important to you, study up on the brands that you are considering, research using online reviews like this one, and take the time to read through some real customer reviews. At the end of the day, the best scope for your 223 is going to be what you are most comfortable using and the one that makes you most excited to get out there and enjoy your firearm.
