AR15 Iron Sight Buying Guide

best iron sight for AR15

Finding the best AR15 iron sight is more difficult than it seems. Today’s market is filled with different models, each of them advertised as the best, but only some actually delivering good results. Some people only buy iron sights as a backup, should their optics run out of batteries or becomes unusable for some reason. Other people, especially those who served in the US Armed Forces prefer shooting with iron sights because they’ve been trained to do so accurately and it comes as a second nature to them. The following guide will explain what features you should take into consideration when you’re shopping for iron sights.

  1. Type: There are two main types of iron sights, and each of them has certain advantages and disadvantages.
  • Foldable Iron Sights – Many manufacturers nowadays choose to make their iron sights foldable. Using flip up sights for AR15 allows you to pop them open every time you want to use them, and close them when you don’t.

The main advantage of using foldable iron sights is that you can have them mounted on your rifle alongside your optics without them interfering. You will be able to switch between using your optics and the iron sights pretty fast if you need to, with just the push of the button or by pressing on the top of the iron sights. Another advantage of using this kind of iron sights is that they’re usually lightweight, and they won’t alter the balance of your rifle, even if you mount them forward on the gas block rails.

The disadvantage of using this kind of iron sights is that there is a possibility of them flipping down when you’re firing, leaving you with no accurate way of aiming. However, this can only happen rarely even when you buy cheap models, let alone when you buy one developed by a renowned manufacturer.

  • Non-foldable Iron Sights – Once you’ve mounted these sights on your rifle, you will be able to acquire your target through them at all times. Switching between your optical sight and the iron sights will be done instantly, without losing so much as a second.

The advantage of using fixed iron sights is that they have less moving parts, so they’re generally more durable than foldable ones. Some of them can also be more resistant to vibration, so they will offer a steadier sight when you fire rounds in quick succession.

The disadvantage of using this kind of sights is that you won’t be able to use them on the same rifle with a scope unless you use high scope rings, which most shooters don’t prefer.

  1. Materials: The material used for the iron sights determines how the sights will behave when you use them. Here are the advantages and disadvantages of using iron sights make out of metal or plastic.
  • Plastic – Many manufacturers rely on plastic for making their iron sights. Since the manufacturing companies understood long ago that most shooters prefer not mounting cheap plastic components on their rifles, they now advertise them as being made out of polymer but make no mistake, this polymer can be more resistant than other materials, but it’s still plastic.

The main advantage of buying plastic iron sights is the price. They are usually cheap, and most people choose to buy cheap iron sights because they generally rely on their optics, and only mount iron sights on their rifles as a backup solution for the optics not working for some reason.

The main disadvantage of using plastic is that you can easily break the iron sights. Some people have difficulties even mounting plastic iron sights on their rifles without breaking them, let alone using them in the field. However, if you’re careful not to bump them in every tree plastic iron sights can last as long as metal ones. Another disadvantage of using plastic iron sights is that plastic melts, so if you mount the sights on parts of your rifle which get hot to the touch, you might find them melted one day when you fire more rounds in quick succession.

  • Metal – Metal iron sights are more durable and sturdier than plastic ones, but they are also more expensive than plastic iron sights.

The main advantage of using metal iron sights is that they are more durable than plastic ones, and they don’t melt, so you can mount them wherever you like without having to worry about them getting hot.

The main disadvantage is that they are usually more expensive than plastic iron sights and many people use them as backup sights, so the cost isn’t justified. However, if you plan on aiming with your iron sights and not a scope or an electronic sight, the iron sights you buy should be made out of metal.

What Does The Iron Sight Actually Do?

The iron sights are actually a system of alignment markers used to help with aiming your rifle without needing a power source like an electronic sight does, but without offering magnification, like scopes do. A typical iron sight system is made out of two separate components.iron sights

  • A rear sight, which is usually larger and placed perpendicular with the barrel, on the rear of the rifle, close to your cheekpiece.
  • The front sight can be mounted in different places on the rifle, depending on the shooter’s preference or the sight’s type. Most common front sights are designed as a post, a ring, or a bead, but different designs can also be used. Both the front and the rear models can be AR15 flip up sights

There are two main types of iron sights designs.

  • The most common design is the “open sight”. These sights have a notch of some kind as the rear sight, and you have to align the notch with the front sight’s bead or post in order to shoot accurately.
  • “Aperture sights” don’t use notches or half circles, but whole circles, making a hole. The hole has to be aligned with the front sight’s bead or post if you want to shoot accurately. This design somewhat limits your field of view, but it should help you focus better on your target and increase your accuracy.
  1. Open Sights: These sights are usually placed at a certain distance from the shooter’s eye. They provide a minimal limitation to the shooter’s field of view, but they’re not extremely accurate. They usually use a post or a bead as the front sight. To use the sight accurately, you have to align the bead or post both horizontally and vertically in the center of the rear sight. The sights are aligned vertically when the top or bead of the front sight is aligned with the rear sight’s top, or when the top of the bead or post is placed just above the base of the U or V-notch. Horizontal alignment is done when the post or bead is perfectly centered in the U or V-notch. If one of the alignments is not perfect, the shot will miss. A popular open sight design is the Patridge sight. Instead of a U or V-notch, this kind of sight uses a rectangular or square front post and a square notch rear sight. Most shooters believe using this kind of sights is more accurate because aligning the front post with the rear opening is easier, as they have the same design.
  • Pros Of Using Open Sights – They are common and cheap, easy to understand and use, lightweight, and sturdy. They can be used in all kind of environmental conditions and don’t need batteries
  • Cons Of Using Open Sights – They are not very precise and they’re difficult to adjust. Aiming with them is not done quickly, and you need perfect eyesight if you want to use them accurately.
  1. Aperture Sights: These sights are also named “peep sights” by shooters, and like the open sights, they too have more designs. Some of them use thin rings which nearly disappear from sight, and they’re named “ghost ring sights”. Others use thicker rings. It’s generally believed that the thicker the ring, the more accurate the sight will be, while a thinner ring will be faster.
  • Pros Of Using Aperture Sights – They are very accurate, and most shooters will be able to find a ring which will allow them to shoot as fast as they want with greater accuracy than open sights. They help you focus better on your target, so you will be able to use them in poor light conditions with better results.
  • Cons Of Using Aperture Sights – These sights are usually more expensive than open sights. Aiming with them is accurate, but not fast. When you use aperture sights, part of your field of view is blocked.

How To Use The Iron Sight Perfectly And Effectively?

iron sight for ar15 reviewsUsing iron sights might seem easy in movies and video games, but the truth is you need a lot of practice if you’re planning on using iron sights with great accuracy and efficiency. The following section will give you some tips and tricks to help you become a proficient shooter when using iron sights.

  1. Fundamentals
  • Every rifle has a front sight and a rear sight. The front sight is usually designed as a post or a bead, and the read sight can be designed to look like a “V”, an “U”, or a simple flat-bottomed square.
  • If you want to aim using iron sights, you have to align the top of the front sight with those of the rear sights and to make sure that the front sight is placed right in the center of the rear sight’s notch.
  • When you aim, all your attention and focus should be on the front sight, making sure it’s aligned perfectly with the rear one. The rear sight should appear slightly blurred, but you should always have a crystal clear view of the front sight.
  • For a perfect alignment, you should bring the top of the front sight at exactly the same level as those of the rear sights, and the open space left and right of the front sight should be equal.
  • While you learn how to properly use the iron sights, you should not focus on the target. This might be counter-intuitive, but if you focus on the target instead of aligning your front and rear sights, chances are you’re going to miss it.
  • When your sights are properly aligned, look at the target and make sure the upper part of your front sight is precisely where you want to hit, and that the sights keep their alignment if you modify your position.
  1. Tips And Tricks

Some people might still have problems with aiming, even though they know the theory behind using iron sight rather well. If this is your case as well, check out the following tips and tricks to find out how you can improve your accuracy using iron sights.

  • A Little Paint Didn’t Hurt Anybody – Many people have difficulties with focusing on the front sight. This is understandable since the sight is the same color as the rear one, and sometimes it even has the same shape. There is a very easy solution if you have this problem.

Take a thin object, like a toothpick or a needle, and dip it into paint. Next, you have to put a little mark in the middle of the top on your front sight. This mark will help you focus on the front sight. Don’t worry if you make a mess of things, you can clean the paint anytime you like, and it will actually disappear with time, so you will have to remake it. Make sure you choose a color that stands out. If your front sight is black, you can use white, light green, bright yellow, or even pink. If your front sight is white, you can use almost every dark color, especially black, red, green, or pink again. You don’t have to worry about pink not being a manly color, you’re holding a rifle, nobody’s going to judge you for that.

  • Training Is Essential – People say that practice makes perfect. This is true for shooting, as well. If you practice shooting with your iron sights, especially after you’ve put a little paint on your front iron sight, you will get better. You will be able to focus more on the sight and make more accurate shots.

Soon, you’ll notice that if you focus long enough on the front sight, the movements around you won’t matter, all that will matter will be the front sight and the target in front of you. This is what shooters call “entering the zone”. Once you reach this level, you will be able to make very accurate shots.
