Every AR-15 owner worth their salt knows they have to clean their firearms to ensure that they work properly each time they take them to the firing range. No one wants their AR-15’s accuracy to suddenly drop off, after all. So it’s important to clean your AR-15 thoroughly at least every few times you use it.

But while AR-15 cleaning kits have most of what you need for regular maintenance or repair, they also usually lack a specific tool for clearing away carbon residue from your AR-15’s bolt carrier. Therefore, you’ll need to get one of the best AR-15 cleaning tools to have everything you need to guarantee your weapon’s safety.

What Tools are Necessary for AR-15 Cleaning?

While many AR-15 cleaning kits can handle the majority of an AR-15’s maintenance needs, there are a few separate tools that are particularly great for ensuring that your AR-15 works well when needed. Among the most essential AR-15 tools are carbon removal tools.

Carbon removal tools are rigid instruments that are used to scrape out carbon buildup from the interior of your bolt carrier or the bolt tail radius. These tools are necessary because many AR-15 rounds, especially cheaper rounds, will leave behind lots of carbon residue or fouling inside your weapon’s barrel or bolt carrier.

These removal tools are shaped like scrapers specifically designed to fit into various components of the AR-15 platform. As a result, you won’t be able to use them with other firearms or platforms in most situations.

You can also find AR-15 multi-tools that might contain additional instruments in addition to a carbon scraper. For instance, these multi-tools may have nylon brushes to clean out the weapon’s components even further. These are particularly handy for getting into the nitty-gritty details of cleaning your firearm and personally ensuring that it’s in peak condition.

Can You Find These in AR-15 Cleaning Kits?

No, not usually. Most AR-only cleaning tools aren’t included in most cleaning kits. This is because AR-15 cleaning tools are specifically built and shaped for the bolt carriers exclusively used by the AR-15 platform. They aren’t meant to be used for cleaning the entirety of the firearm and its various components.

Therefore, AR-15 owners that want to thoroughly clean every part of their firearm will need to purchase an AR cleaning kit and one of these AR-15 cleaning tools as well. Both must be used in conjunction to ensure proper firearm performance.

Another thing not usually included in cleaning kits is a quality bore cleaner.
