Types of AR-15 Sights

Before you can decide which sight to buy, you will need to figure out which type you want to use. Some shooters prefer to use iron sights, which don’t rely on optics to help mark their targets. Other gun enthusiasts prefer to use something a little higher tech.

  • Red-Dot Sight. Many of the best AR-15 sights employ a red dot method. A tiny light-emitting diode, commonly called a LED, will create a light that is reflected into a mirror. From there, the mirror directs the light onto the lens, and then you’ll see it while you are looking into your sight.

They work best for targets that are within 100 yards of you, although they can help with longer distances as well. Although these types of sights are called red dot, that does not mean the color of the light you’ll use will always be red. The lights can be a variety of colors.

  • Iron Sights. Iron sights, or open sights, are a way to help shooters with their accuracy that doesn’t involve anything terribly high tech. It uses an alignment marker, which is usually made out of metal. Iron sights are trickier to use, and some shooters consider them a relic of the past because there are easier methods available now of honing in on your target. Iron sights, however, are a popular backup method to optic sights because optics can sometimes fail to work. Without backup iron sights, your shooting will be wildly off target if your optics fail.
  • Telescopic Sights. These types of sights are often called scopes. They use a telescope in addition to a graphic image pattern that helps shooters get a lock on their target.
  • Laser Sights. Laser sights use a small light that features a light beam that runs parallel to the barrel of the gun. The laser light can be seen even a long way away, although it typically doesn’t work well in bright light situations.

1. Magpul Industries USA MBUS Generation II

This sight is made of tough polymer instead of metal. That makes it a lighter option than a standard metal sight. It’s also strong enough to put up with all the abuse a sight can take.

It is a spring-loaded flip-up sight that you will not have to struggle to open. It can be triggered by pressing on either side or the top. Once you’re done using it, it retracts easily back into place.

These sights are simple to install – just slide them on. They only take a few seconds to adjust before you’ll be happily trying them out with shot after shot. They stay on tight. There’s no vibrating, shifting or moving, which gives you accuracy every time you use them.

With this sight, you’ll be able to shoot with both your eyes open. You’ll be able to quickly find and get a lock on your target, which matters to shooters who are in high-pressure situations where every second counts.

This battery-powered sight has rear-facing controls, which allows you to easily turn it off when you don’t need it. You can also quickly adjust the 10-dot intensity levels. When you are done using it and turn it off, the next time you’ll turn it on, it will automatically go to the last setting you had it set on. That saves you more time to spend on shooting and less time you’ll need to fuss with your settings.

The red and green dots used by this sight are clear and are visible even in tough conditions.
