Best AR-15 Cleaning Tools

Best AR-15 Cleaning Tools (2021 Review)

Cleaning is critical for keeping your AR-15, or any firearm, in good condition.

No matter what ammo you use, shooting causes carbon, lead, and other types of residue to coat the inside of your gun. The more you shoot, the more of this build-up that forms. If you don’t remove it via cleaning, that build-up can cause accuracy issues, mechanical malfunctions, and even damage to your gun.

A rifle cleaning kit is the basic, go-to cleaning option but sometimes you need something different. AR-15 cleaning tools allow you to detail and deep clean your rifle and can also provide a more compact alternative to a cleaning rod. 

In this guide, we’ll talk all about AR-15 cleaning tools. We’ll talk about what they are and what different types are available, discuss what you should look for when choosing AR-15 cleaning tools, and finish up by going over a few of our favorites. 

You can get a sneak peek at those AR-15 cleaning tools by taking a look at the list below, but for now, let’s get started with the basics.

What Are AR-15 Cleaning Tools?

Best AR-15 Cleaning Tools

Anything you might use to clean an AR-15 can be considered an AR-15 cleaning tool, but here we’re focusing on the things you won’t find in most gun cleaning kits. That means we’re not talking about traditional cleaning rods, cleaning patches, bore brushes, or bore mops. 

For those kinds of things, look at the tool-specific guides we just linked to or check out The Best Cleaning Kits or The Best AR-15 Cleaning Kits.

Instead, we’re going to look at less common AR-15 cleaning tools. These include tools designed for deep cleaning a specific part of the AR-15, general-purpose detailing tools, a gun cleaning multi-tool, and an alternative to a traditional cleaning rod. 

What Are The Different Types Of AR-15 Cleaning Tools?

Best AR-15 Cleaning Tools

Different tools do different things, but they’re typically all focused on cleaning the upper receiver. The bore and chamber tend to get special attention, but there are also plenty of cleaning tools that are more focused on the action. 

There are also multi-tool type cleaning tools that have a bunch of cleaning tools built-in to allow them to clean a lot of different parts of the AR-15.

Finally, there are tools that have a single purpose, but that purpose is still useful for a variety of parts. Picks and utility brushes are good examples of this.

We’ve included tools of all of these types in our recommendations.

What Do You Look For In The Best AR-15 Cleaning Tools?

Best AR-15 Cleaning Tools

What exactly you need to look for in an AR-15 cleaning tool depends on what you want your cleaning tool to do. There are, however, a few things that you should look for in a cleaning tool, no matter what your needs are.

First, make sure that it does, in fact, actually meet your needs. For example, don’t buy a multi-tool just assuming it has all the cleaning tools you could want. Take some time to consider what all functions you want your multi-tool to have and make sure that the multi-tool you’re looking at actually has them. 

You’ll also want to make sure that any AR-15 cleaning tool you have is high-quality. Is it made from durable materials? Is it well constructed? Is it effective? Checking out reviews from other customers is a great way to get an accurate idea of the quality of the tool and how it performs in the real world.

You’ll also want to consider the size of the cleaning tool. If you want something that you can toss in your range bag, you probably want something more compact. If you just want something to use at home, you can get away with a larger tool.

Now that all of that’s out of the way, let’s talk about the cleaning tools.

1. Otis B.O.N.E. Tool (Our Top Pick)

Otis B.O.N.E. Tool

Our overall top pick is the Otis Technology BONE Tool.

This AR-15 cleaning tool is specifically designed to clean carbon buildup and fouling from the bolt carrier group (BCG) in AR-15 style MSRs. It has built-in scrapers for the bolt carrier, bolt, and firing pin, as well as an 8-21 threaded hole so it can be attached to a standard cleaning rod and used as a T-handle.

Just make sure you choose the 5.56 NATO/.223 Remington version, since it’s also available in a 7.62 NATO/.308 Winchester model for the AR-10.


  • Compliments a basic AR-15 cleaning kit well
  • Scrapers for the entire bolt carrier group
  • Very compact


  • Best for cleaning off a large amount of build-up because you’ll have to follow up to remove the last bits of fouling

2. Hoppe’s Gun Cleaning Tools Combo (Best Budget)

Hoppe’s Gun Cleaning Tools Combo

Our top budget pick is the Hoppe’s Gun Cleaning Tools Combo. As a combo set, it includes a few different tools. 

The four double-ended picks have tips of different sizes and angles for getting in a variety of crevices. 

The utility brush has two ends, one larger for scrubbing bigger areas and the other narrower and somewhat shorter for getting into harder to reach places. 

The four swabs have soft, flat ends for precision application of solvent or oil. Unlike cotton swabs, they can be cleaned and reused.


  • A good complement to your existing AR-15 cleaning kit because it allows you to get into those nooks and crannies that most cleaning kits don’t have the tools for
  • Nine different tools for a variety of different detailing needs
  • Price


  • Not great for scraping large areas or tricky rounded pieces like the firing pin

3. Real Avid Carbon Boss (Best High End)

Real Avid Carbon Boss

The Real Avid Carbon Boss is the way to go if you want a highly multifunctional AR-15 cleaning tool.

It’s a multi-tool with scrapers for extractors, bolt faces, bolt carriers, bolt cam pins, small firing pins, large firing pins, bolt lugs, firing pin faces, bolt tail interiors, and bolt tail exteriors. It also has a phosphor bronze bolt tail brush to remove carbon from the bolt tail, firing pin, and other small, thin parts.

But it’s not just a carbon removal tool. This multi-tool also has a pin punch, detailing brushes, and a cotter pin puller.


  • 13 different tools
  • Pin punch helps with takedown and disassembly before you even start cleaning
  • Comes with a nylon sheath for storage and carry


  • Relatively costly
  • Even with all the tools built-in, it’s still really only for cleaning the bolt carrier group

4. Otis Technology Star Chamber Cleaning Tool


Otis Technology Star Chamber Cleaning Tool

The star chamber of AR rifles can be tricky to clean, which is why Otis introduced the Otis Technology Star Chamber cleaning tool.

It uses star-shaped chamber cleaning pads to get into the chamber easily and effectively. You can use the pads the same way you’d normally use a cleaning patch, like to apply gun cleaning solvent or CLP and, after you’ve used a chamber brush or the built-in chamber scraper, to remove loosened fouling.

It comes with 6 felt cleaning pads, but you can get more separately. There’s also a version for the AR-10, so make sure you select the right model.


  • The coated brass nose piece centers the tool but won’t hurt your gun
  • Has standard 8-32 threads, so you can also attach standing cleaning rod attachments
  • Far more effective than standard chamber cleaning methods


  • A bit costly for how specialized it is
  • Have to continue to buy cleaning pads, which are far more expensive than patches

5. Real Avid Bore Boss

Real Avid Bore Boss

Last up is the Real Avid Bore Boss, a bore cleaner tool that’s similar to a bore snake.

It has a 32-inch long cable with a phosphor bronze bore brush and an 8.5-inch long braided mop attached to the end. All of this feeds into the round handle for compact, convenient storage.

Unlike a cleaning rod, this set up allows for a fast, easy bore cleaning without disassembling the rifle. It’s more compact than a cleaning rod and its various attachments as well.

It’s available in a ton of different calibers, so once again make sure you’re getting the right model.


  • Allows for convenient cleaning without disassembling the rifle
  • Compact, so it’s great for tossing into a range bag for quick bore cleans
  • Available by itself or as part of the Real Avid Gun Boss Multi Kit


  • Not as thorough as a cleaning rod, so it’s not a substitute
  • Single-purpose

Final Thoughts On AR-15 Cleaning Tools

With AR-15 cleaning tools like these, you don’t have to be a gunsmith to give your AR-15 a deep, thorough cleaning. Each is an excellent, high-quality tool, but they each have different purposes, so just choose the tool or tools that best fit your needs.

Of course, they’re not replacements for a cleaning kit so if you don’t have one already, be sure to check out the Best AR-15 Cleaning Kits to get your basic cleaning items to start. For the outside of your gun, you’ll want to take a look at the Best Gun Cleaning Cloths as well.
