6 Best Accessories for the AR-15

Best AR-15 Accessories

The AR-15, or Armalite Rifle, has been a staple of American firearms manufacturing for over 60 years. It’s a tool that serves lots of uses, and many AR-15 options come ready to shoot right out of the box. 

That doesn’t mean the platform can’t be enhanced with quality accessories, however. At Frontier Justice, we carry a variety of AR-15 add-ons that increase the usefulness and functionality of your tool. 

Read on to learn more about the 6 best AR-15 accessories every owner needs. You can also reach out to our firearms experts or visit us at our Lee’s Summit, Kansas City, and Omaha stores to see our best AR accessories firsthand. 

Sights and Optics

Many AR-15s don’t come with built-in sights or optics out of the box, even iron sights. That’s advantageous for owners, however, because you can make sure your optic or sight is perfect for your needs. 

We carry a huge variety of sights and optics both in our stores and online, so we are bound to have one that fits your needs. 


A sling is an essential item for any AR-15. First and foremost, it keeps the rifle connected to you. Secondly, it allows you to release the firearm while not in use, giving you the ability to complete whatever tasks are necessary. From navigating the outdoors to transitioning from a rifle to a pistol, having a sling is an absolute necessity for every AR-15.

With many different sling and strap options available, you can find the exact sling to fit your needs and comfort level.

Mounted lights

One of the four fundamental rules of firearm safety is to know what you’re shooting at, and what lies beyond. In a dark setting or when shooting at night, if you don’t have a reliable light mounted to your AR you won’t be able to identify your target. These mounted lights are particularly useful in home defense scenarios, when you likely won’t have time to turn on the lights in your house. 

Another of the fundamental firearm safety rules is to never point a firearm at something you don’t wish to destroy. This is why we recommend having a handheld light in tandem with a weapon mounted light, to give you the opportunity to see in the dark without flagging loved ones with a live carbine. 

Spare magazines

If you purchase your AR or build your own, you’ll most likely end up with a magazine that holds 30 rounds, the standard magazine for ARs. There are plenty of other magazine options, however, including extended magazines that can hold more than 30 rounds. 

One of the major advantages of an AR is its round capacity, so we highly recommend exploring expansion options or even just owning spare magazines. You should aim to have roughly 8-10 magazines per AR-15. With their low price point and high quality, extra magazines are essential to have on hand. 


A firearm needs to be fed! Stocking up on enough ammo to practice your shooting and keep your magazines loaded in case of emergency is a critical part of firearm ownership. 

We carry many options for ammunition, including hollow point rounds that are perfect for home defense. 


Owning an AR and all the accessories isn’t going to teach you how to use it. To truly answer the question what is an AR, you need to practice your skills and learn the proper techniques for shooting. 

Our AR-15 basics class gives new owners and prospective owners a basic orientation with the AR-15 platform. This class takes place both in our classroom and in our indoor shooting range, mixing both instruction and practical application of what you’ve learned.
