There are many sights out there to choose from, and they all have their own pros and cons.

How to Use It with an AR 15?

How to Use It with an AR 15

With the use of modern sights and scopes, using your AR iron sights can seem a little foreign at times and there are some nuances when getting up and ready with the iron sights on your AR 15. Moreover, there are some misconceptions in regards to the view provided by the sight as well, which will prevent newbies from adjusting the sights properly.

First off, clearing out the misconceptions planted by modern video games and simulations. Often in these games, the first-person focus in the game in regards to the plain iron sight is incorrectly portrayed, and in reality, you will not be able to focus on the front-sight while keeping tabs on your target without blurring out some of the front-sight.

That is, the picture-perfect “blur everything out and focus on the target” we often see portrayed in these games are unfortunately not possible in reality due to the way the human eye functions. Therefore, using iron sights with an AR 15 requires educated calibration and ample practice to get used to aiming down iron sights.

How to Adjust AR Sights?

How to Adjust AR Sights

So, the question remains, how to adjust the iron sights on your AR 15 to land the perfect shot?

Follow these steps to the tee when setting up your iron sights so when you do find yourself in a situation wherein you have to rely on them, your shot is accurate and hits the target.

  • Ensure that your iron sights are properly installed on your AR-15 and mounted firmly. If your sight is loose or you can move wiggle using just your hand the sight is not securely mounted and will only become worse as you use your gun more. Therefore, the first order of business is to get it securely, and tightly mounted onto your AR-15.
  • Next, you should ensure a mechanical zero of the iron sights. As you already know, there are two main sights, the rear and front sights. You will have to zero these individually. Firstly, for the rear sight, ensure that the aperture is exactly in the middle of the main body, or housing, of the sight. This can be done with simple math. Adjust the aperture to the right or left. Next, move it to the other end and count the number of clicks it takes to get it there. Finally, just halve the number of clicks and you will have the number of clicks you need to adjust the aperture by, to center it within the main housing. Next up is the front sight. Here, you only need to adjust the base of the front sight until it is level with the main housing of the sight. You can either use a depress the detent on the front sight and turn the post at the same time. Using a special tool is recommended in this case.

After these steps, your sight should be mechanically zeroed in, and you are ready to get some test shots in.

As with any standard sight adjustment procedure, aim for a target about 25 yards away from the rifle and shoot multiple times consistently, while keeping your body and shooting arm relaxed. Ensuring that there is little variation between the shots will help you adjust zero quickly. After firing the initial rounds, head over to the target, take your measurements and adjust your iron sight accordingly.

To adjust the aim and move the impact of the bullet upwards or downwards, you will need to adjust the front sight. And in the case of left and right adjustments, changing up your rear sights is the way to go. Therefore, use the adjustment knobs on your sights purposefully to adjust the direction of your sight accordingly. The most critical aspect when adjusting the zero of your rifle against your iron sight is the MOA adjustment values.

Firing your rifle from different distances will have an MOA to bullet impact ratio, which varies from rifle to rifle. Therefore, it’s important to experiment with your rifle first, adjust clicks accordingly, and then fire your calibration shots before ticking away at the front and rear sight settings. Once all the calibration is done, fire once more at a test group to ensure that your rifle is zeroed in and you are good to go.

What to Consider Before Buying an Iron Sight?


The material of the sight is very important if you want to use it for a long time in rough conditions. In the case of polymer iron sights, you will get a cheaper deal but the sight will not live through touch impacts and rough operations. The iron sights are made from steel or aircraft-grade aluminum and offer the highest amount of protection from rough usage. Therefore, consider your usage when deciding on the material of your backup sights, while polymer serves as a cheaper beginner option, a steel or aluminum sight will be a companion for your AR15 for many years.

Gas Block vs. Same-plane

Gas blocks sights are designed to accommodate the fact that gas blocks raise the front sight by about a quarter of an inch, and the backup iron sight configuration has to compensate by raising the rear by that amount as well. If you do not need to mount your iron sights on a gas block, you are well-off with a same-plane sight. Here, the rear and front sights are mounted on a plane rail, which means they will always be in the same height without requiring additional adjustments.

Fixed vs. Folding

Fixed sights bring no additional moving parts on your rifle, and so, adds to the sturdiness of your AR 15 as you do not have to worry about anything coming loose through continuous use. Additionally, you can just set them once and never have to worry about configuring them again, which means they are always ready for action. Folding sights play on the ‘backup’ aspect of iron sights and are not always protruding out of your AR 15. Call them into action when you need them, and tuck them away when you don’t. The decision between the two comes down to how often you will be using your irons sights. For frequent usage, fixed iron sights are better and for rare usage, all the best irons sights come with quick folding mechanisms


Ease of use depends on the build quality and skill level. When picking out the right sight, take into consideration how long you will be using it for and for what purpose, as it will dictate how comfortably you will be able to carry it out on the field and your enjoyment when using it during lengthy hunts. For newbies, getting used to a lighter, cheaper sight is not uncommon before investing in a heavier more durable long-term solution for your sighting needs.

Co-Witness Position

Although the co-witness position comes down to personal preference, it’s important to distinguish between the two. With a lower third co-witness position, your backup sights will be mostly out of the field of view of your main optics, however, they still serve as a minor form of distraction, and users often have trouble focusing on the target when the backup sights are in the lower third position. In the case of an absolute or 100% co-witness position, you have the advantage of always having your backup sights in the field of view of your main optics, and, you will be able to rely on them the instant your main optics fail. However, given that flip-up optics are more widely used, professionals rarely take a second to switch their back up iron sights from an erect to resting position and vice versa. In these cases, trading off better accuracy in favor of lower third co-witness comes off as redundant. Therefore, if you want higher accuracy and the sight supports folding, choosing the one that supports absolute co-witness is often recommended.

Sight View

The last consideration is often between the inline or offset views. In an inline view, the iron sights take a co-witness position. Therefore, as long as your main optics lens does not get damaged, you will always have a clear view of your iron sights as well. In the case of an offset sight, they are positioned 45 degrees off the main axis of the barrel and serve their purpose as backups once your turn your rifle around a bit.

Don’t Buy A Fake Iron Sight

The low price can be quite deceiving, so don’t fall for it. Often times you’ll see deals on fake iron sights that are advertised as the real deal but don’t work the way they should. So you need to find a regular trusted dealer or buy with seller protection. You will find a few websites that offer seller protection. It’s usually a small fee but helps to protect you from issues with the sight. One of the best places to purchase is Amazon.

A Note on Warranties

When purchasing any sight for your airsoft gun please check about the warranty first. All sights will work perfectly fine for a couple of months, however, the warranty may differ from sight to sight. There are sights which have a 1-year warranty, while others last 10 years.
