Types of Iron Sights
Aside from the mentioned factors, it’s also advisable to gather information about the different types of iron sights. You can actually categorize the iron sights based on their aperture.
There is what we call as the aperture sight or peephole sight, which refers to the hole that you’re looking through using the rear sight. It’s advisable to line up in the hole’s front sight post to guarantee the proper aim.
The majority of iron sights actually come with two various sizes for their aperture.
The bigger one is ideal in case you’re dealing with short-range situations. This promotes ease when planning to acquire your target quickly.
The smaller aperture, on the other hand, is perfect in case of long-range shots where you need to have the perfect accuracy.
Another option you have is the post-and-notch sight guaranteed to offer a wider field of view.
Lastly, there is the 45-degree or offset iron sight. It’s an excellent choice just in case you want to transition quickly from short and long-range targets.
To use this, you just have to tilt your rifle slightly then look down at it normally. It’s perfect in case you’re in a situation that requires you to switch target distance quickly, like in combat or 3-gun shooting competition.
How to Find the Best Iron Sights?
Now that you’ve gathered some relevant details about the top iron sights in the market today, it’s time to understand how you can actually make the best choice.
Ensure that you carefully weigh the following considerations and factors to increase your chances of getting the best iron sights for AR15:

Note that you can’t expect all metal sights to fit the AR15 rifle system. That said, it’s crucial to look for an iron sight, which is compatible with your AR15. Such offers an assurance that you can mount it on the appropriate gun rails.
In this case, learn about the actual manufacturer of your AR15 gun rail so you can easily find an iron sight, which perfectly suits it.
2. Overall Setup of Your AR15
Another vital factor to consider is the overall setup of your AR15. You need to consider the setup because it will help you figure out whether you need a fixed or a folding iron sight.
The fixed iron sight is beneficial in the sense that it does not come with any moving parts; hence, making them almost indestructible. You can also expect it to be always ready. You just have to set it up then let it do its job.
The folding sight, on the other hand, performs another function. It’s an ideal option in case you want it flip it down to ensure that it’s out of the way when unused.
If possible, choose the fixed iron sight if what you’re looking for is the one, which you can use as your AR’s primary targeting system.
However, if you’re planning to use one as a backup then it’s advisable to go for the folding sight.
3. Ease of Use
Another important consideration is whether or not the iron sight is easy to use. Avoid those that require a lot of effort to mount.
Also, avoid complex ones that still require you to use a screwdriver or wrench in case of adjusting elevation. Note that the best iron sight is that which allows you to locate your target quickly. It is also easy to adjust.
Make sure that you look for an iron sight, which is easy to adjust. It should have a capability integrated into it, which makes it possible for you to adjust its elevation and windage. Such promotes ease when using this product.
5. Speed of Deployment
You also need to look for an iron sight, which you can quickly deploy. Such is crucial especially if you’re in a tactical situation and you’re dealing with a scope failure.

Ensure that you can easily and quickly flip it into position with just one press of a button. If possible, it should come with angle sights, too, that can be activated in case you turn your gun at a slight angle.
Check out the material used in the iron sight, too. The material should be sturdy enough and withstand tough use. Among the common materials used in this product are actually aluminum, steel, and polymer.
Note that while steel has the highest level of durability, allowing it to serve its purpose for the long term, aluminum is also a tough material, which is more lightweight.
Lightweight materials are easier to manage, making iron sights made of aluminum great options, too.
How to Aim with Iron Sights?
To aim using your iron sight, it’s crucial for you to have a front sight. It could be a post or block, forming the shape of an “I”. It’s also necessary to have a notched rear site, forming the shape of a “U”.
Put the front sight in the middle of the rear sight. Ensure that the topmost part of the rear and front sights line up perfectly. It’s also necessary for the front sight to have a similar amount of space in both the right and left of the rear sight.
Start to aim by focusing on the front sight. Observe the alignment with the rear, which should be a bit blurred. The front, on the other hand, needs to be really clear.
Aim at it while letting all the others vanish. Avoid looking at your target. Your goal should be to focus on the front sight as well as how aligned it is with the rear sight.
You might need to glance at the target from time to time, though as a means of getting the perfect alignment for the sight. However, once you got the alignment, you have to bring back your focus to the front sight.
