Fancy optics get a lot of attention, but it’s a mistake to underestimate classic iron sights. They’re cheap, easy to use, and extremely durable. They work well on their own, but they can also work as a backup to other aiming systems. Every AR 15 should have a set, and finding the best AR 15 iron sights is vital for optimizing the gun’s performance. The best options are quick to adjust, offer high visibility, and are fairly light. Sorting out the best options can be hard, but we built a list of ten that balance those traits to make it easier.
10. Ozark Armaments Backup Sights
The backup sights from Ozark Armament are some of the best AR 15 iron sights for shooters on a budget. Their milled aluminum construction makes them much more durable than most other sights at this price range, and they will hold up to normal use. They’re fully adjustable for both windage and elevation, and their adjustments are precise enough to be useful. They don’t fold quite as flat as the more expensive folding sights, but that’s a minor problem. New and casual shooters should consider these due to their price, but dedicated shooters should only consider these as a cheap backup to other optics.
9. Trinity Force QF B.U.S.
QF B.U.S. sights are another strong budget option. They are good enough to serve as a primary sighting system, but their intended role is that of a backup. The rounded, open shape of the front sight is good for quick target acquisition in tactical scenarios, and it adjusts for elevation and windage reasonably well. These sights are also fairly good at absorbing shocks since they include a strong locking mechanism to keep them in position. They’re ideal for new shooters who want tactical sights without a big investment.
8. Blackhawk Fixed BUIS
Blackhawk’s BUIS is an iron sight for people who value durability. Both the steel and aluminum components have finishes that boost durability, and the simple design makes it hard to do serious damage to the sight. It also keeps everything aligned properly, making this a fairly reliable sight. The downside is that it only adjusts for windage, and doing so is harder than adjusting many other sights. Shooters who don’t need to make frequent adjustments should try this, but others should steer clear.
7. Dueck Defense Rapid Transition
Rapid Transition sights mount on an upper Picatinny rail, but they are offset to make sure they don’t interfere with the other optics on the gun. Using them requires rotating the rifle. It takes a little practice to get used to it, but most people can handle them without any problems. Both left-handed and right-handed variants are available to make it easier to use. These sights are made from aluminum, which provides a good compromise between durability and weight. Try them if you want to have both iron sights and advanced optics available at a moment’s notice.
6. Aero Precision Flip-Up Sight Set
The sights from Aero Precision can excel in most roles. They include a spring mechanism that unfolds the sights with the push of a button, which provides convenience and the assurance that they will be in the right position every time. The rear sights include a dual aperture system, so they’re appropriate for most ranges. They’re a little bit heavier than most other aluminum sights, but not enough so to cause problems. Try them if you want a set of simple sights that can function equally well as a primary system or a backup.
5. Daniel Defense Rock and Lock
Rock and Lock sights are fixed, but they have a compact and snag-free design that prevents that from being an inconvenience. They are designed with small weapon lights in mind, so it’s easy to reach around the sights to turn one on without significant movement. They’re unusually easy to mount, and they tend to stay in position even after serious shocks, so they’re a great choice for novices who want easy installation. They’re one of the top choices for new or intermediate shooters who want convenience without losing any quality.
4. Troy Dioptic Folding Sight
Troy’s Dioptic sights excel at rapid target acquisition. They have an unusual shape that naturally centers the eye in the right position to make aiming fast. The sights are also a decent choice for long-range use because they come with two quick settings, one of which works up to 500 meters. They are made from a mixture of aluminum and steel, so they can also hold up to rough use in most environments. They’re the best AR 15 iron sights for tactical purposes, but they’re also reasonably good for hunters and target shooters.
3. Trijicon CP25
|Style||Three-Dot Night Sight|
CP25 sights are designed for night use. They include gas lamps that glow in the dark without needing any batteries, which makes them the best AR 15 iron sights for use in the dark. The sights rely on silicon rubber to provide cushioning and absorb shocks, which keeps them fairly stable. That combines with an aluminum case to create a sturdy set of sights that can hold up to an occasional nocturnal accident. Give these sights a try if you want to shoot in the dark, but get something cheaper if you aren’t going to need the illumination.

2. GG&G Gas Block
The GG&G sight is among the best AR 15 iron sights for those who want a gas block system. The sight is unusually stable because it relies on a tri-point clamping system and a spring-loaded locking system to hold everything in position. It’s also fairly durable due to its solid steel construction, but that does come at the cost of increased weight. An optional dovetail rail provides space for mounting a flashlight or other accessory, but that increases the weight even more. Try this sight if you want something stable and can handle the weight, but look elsewhere if you need something light.
1. Magpul MBUS
The MBUS sight is not only one of the best AR 15 iron sights, but one of the only polymer sights worth using. The quality of manufacturing is high and the polymer resists most impacts, so it can hold up to plenty of abuse in spite of its material. It also helps to keep the sight light. It adjusts for windage easily, and the knob is big enough that most people can use it without taking their gloves off. It’s an appropriate choice for anyone who wants to minimize weight without sacrificing much durability.
Making The Right Choice
Iron sights are the most basic and useful accessories for most weapons. There are simply no better ways to ensure that adequate aiming is always possible. Their sheer importance means that every shooter should strive to get the best AR 15 iron sights for their needs.
