How to Clean an AR-15: A Complete Step-by-Step Guide
How to Clean an AR-15: A Complete Step-by-Step Guide
Proper firearm maintenance is one of the most important parts of responsible AR-15 ownership. Regular cleaning helps remove fouling, carbon, dirt, and debris while giving you an opportunity to inspect your rifle and identify potential maintenance issues before they become problems.
Whether you're new to the AR-15 platform or an experienced shooter, having a consistent AR-15 cleaning routine can make firearm maintenance faster, easier, and more organized.
In this complete guide, we'll walk through how to clean an AR-15, what you need, the basic cleaning process, and some common AR-15 cleaning mistakes to avoid.
What You'll Need to Clean an AR-15
You don't need an enormous collection of specialized tools to properly maintain an AR-15. A quick trip to your local gun shop, Badass Patriot, Walmart, or Amazon can get you up and running quickly.
A basic AR-15 cleaning kit should include:
Quality gun cleaning solvent or cleaner
Gun lubricant
Cleaning patches
Cleaning rod or appropriate cleaning system
Bore brush
Chamber brush
Nylon or polymer cleaning brush
Cotton swabs or cleaning swabs
Microfiber or lint-free cloth
Small parts tray or container
Appropriate AR-15 cleaning tools
A dedicated work surface can also make the process considerably easier. That's one reason Badass Patriot developed purpose-built AR-15 cleaning and maintenance tools designed specifically around the way modern sporting rifles are cleaned, serviced, and maintained.
Step 1: Make Sure the Rifle Is Unloaded
Safety comes first.
Before beginning any cleaning or maintenance:
Point the rifle in a safe direction.
Remove the magazine.
Lock the bolt to the rear.
Visually and physically verify that the chamber is empty.
Check the firearm again before proceeding with maintenance.
Do not begin cleaning until you are certain the firearm is unloaded.
If you are unfamiliar with the operation or disassembly of your specific AR-15, consult the manufacturer's owner's manual.
Step 2: Prepare Your Work Area
A clean, organized work area makes AR-15 cleaning and maintenance much easier.
Ideally, use a stable surface with enough room to organize the rifle, cleaning supplies, and small components. This is where a dedicated firearm cleaning station like our Badass AR-15 Station and Badass Gun Cleaning Mat's can be particularly useful.
A good cleaning platform can help keep the rifle stable while providing an organized area for cleaning rods, brushes, patches, tools, and small parts.
The goal is simple: keep everything visible, organized, and within reach.
Step 3: Separate the Upper and Lower Receiver
Follow the manufacturer's instructions for your specific rifle to separate the upper and lower receivers. Not all AR-15 rifles are the same!
Once separated, you can access the major components that require cleaning and inspection.
For most routine maintenance, concentrate your attention on areas where carbon, fouling, and debris commonly accumulate, including:
Bolt carrier group
Bolt
Chamber
Barrel
Gas system components
Upper receiver
Feed ramp area
Lower receiver
Trigger and fire-control area
You don't necessarily need to completely disassemble every component every time you clean your AR-15.
A good cleaning routine should be thorough without being unnecessarily complicated.
Step 4: Clean the Bolt Carrier Group
The bolt carrier group, or BCG, is one of the most important areas to clean during routine AR-15 maintenance. Carbon and fouling can accumulate on the bolt, carrier, and other surfaces.
Apply an appropriate firearm cleaner to the components and use a nylon or polymer brush to remove carbon and debris.
Pay particular attention to:
Bolt face
Bolt lugs
Carrier surfaces
Gas key area
Firing pin area
Carbon buildup
Avoid using excessive force or tools that can unnecessarily damage firearm surfaces. After cleaning, wipe the components thoroughly with a clean, lint-free cloth.
Step 5: Clean the Chamber
The chamber is another critical area of the AR-15.
Use an appropriate AR-15 chamber brush to remove carbon and residue from the chamber and locking-lug area. A clean chamber helps ensure that fouling and debris don't accumulate where the cartridge seats.
Take your time here rather than simply running a patch through the bore and calling the rifle clean.
Chamber cleaning is an important part of a complete AR-15 cleaning routine.
Step 6: Clean the Barrel and Bore
The barrel should be cleaned from the chamber end whenever the firearm's design and available equipment allow it.
Use an appropriate cleaning rod or bore-cleaning system along with the correct bore brush and patches for your caliber.
A basic process is:
Apply an appropriate firearm cleaning solution.
Run the cleaning tool through the bore as directed by the cleaning-product manufacturer.
Use the appropriate bore brush to loosen fouling.
Follow with clean patches.
Continue until the patches are reasonably clean.
Inspect the bore and barrel.
Avoid forcing cleaning equipment through the barrel or using an incorrectly sized brush or accessory.
The objective isn't necessarily to make every component look brand new after every range trip. The objective is to remove fouling, inspect the firearm, and maintain it properly.
Step 7: Clean the Upper Receiver
Use a nylon or polymer brush and a lint-free cloth to remove loose dirt, powder residue, and carbon from accessible areas of the upper receiver.
Pay attention to areas around:
Bolt carrier travel surfaces
Chamber
Feed ramps
Ejection port
Charging-handle area
A small cleaning brush and quality gun-cleaning swabs can make it much easier to reach tight areas.
Step 8: Clean the Lower Receiver
The lower receiver generally requires less aggressive cleaning than the bolt carrier group. Remove loose debris and residue using a suitable brush and cloth. Pay particular attention to areas where dirt, powder residue, and other debris may accumulate.
Avoid unnecessarily flooding the fire-control area with cleaning chemicals or lubricant.
If you notice unusual wear, damaged components, or anything that doesn't look right, stop and consult the firearm manufacturer or a qualified gunsmith.
Step 9: Clean the Charging Handle
]The charging handle can accumulate carbon, dust, and residue during normal use. Wipe it down with an appropriate firearm cleaner and lint-free cloth.
A small polymer brush can help remove buildup from hard-to-reach areas. Once clean, inspect it for obvious signs of excessive wear or damage.
Step 10: Inspect Everything Before Lubrication
Cleaning isn't just about removing dirt.
It's also an opportunity to inspect your AR-15.
Look for:
Excessive wear
Cracks
Damage
Unusual carbon buildup
Loose or damaged components
Abnormal markings
Signs of corrosion
If something appears damaged or abnormal, don't simply lubricate it and put the rifle back together. Have the firearm evaluated by the manufacturer or a qualified gunsmith when appropriate.
Step 11: Lubricate the AR-15
After cleaning, apply an appropriate firearm lubricant according to your rifle manufacturer's recommendations.
Lubrication is important, but more isn't necessarily better. Excess lubricant can attract dirt, dust, and powder residue.
Apply a light, appropriate amount to the manufacturer's recommended lubrication points. If you're unsure where your specific AR-15 should be lubricated, consult the owner's manual.
Step 12: Reassemble and Perform a Safety Check
Reassemble the rifle according to the manufacturer's instructions.
Once assembled, verify that everything is properly installed and functioning as intended. Do not force components together.
If something doesn't fit or function correctly, stop and consult the manufacturer's instructions or a qualified gunsmith.
Step 13: Wipe Down and Store Properly
Finish your AR-15 cleaning routine by wiping down the exterior surfaces with an appropriate firearm cloth.
If the rifle will be stored, follow the manufacturer's recommendations for storage and corrosion protection. Store firearms securely and in accordance with applicable laws and safety practices.
How Often Should You Clean an AR-15?
There isn't one universal cleaning schedule for every AR-15.
How often you clean your rifle depends on factors such as:
How frequently you shoot
Ammunition
Shooting environment
Dust and debris
Weather conditions
Storage conditions
Manufacturer recommendations
A rifle used frequently in dusty or dirty conditions may require more attention than one used occasionally at an indoor range.
Rather than relying exclusively on a round count, establish a consistent inspection and maintenance routine based on your firearm, usage, and manufacturer's recommendations.
Common AR-15 Cleaning Mistakes
Even experienced shooters can make firearm-cleaning mistakes.
1. Over-lubricating
Too much lubricant can attract dirt and carbon.
Use the amount recommended for your firearm and lubricant.
2. Ignoring the Chamber
Cleaning the bore isn't the same thing as thoroughly cleaning the chamber.
Make chamber cleaning part of your regular AR-15 maintenance routine.
3. Using the Wrong Tools
Improper tools can make cleaning more difficult and may potentially damage firearm surfaces.
Use cleaning tools designed for the firearm and caliber you're maintaining.
4. Completely Disassembling the Rifle Every Time
Routine cleaning doesn't necessarily require complete disassembly.
Follow your manufacturer's maintenance recommendations and avoid unnecessary disassembly.
5. Cleaning Without Inspecting
Cleaning gives you an opportunity to identify wear, damage, corrosion, and other issues.
Don't rush through it.
6. Using Excessive Force
If a component or cleaning tool isn't moving normally, stop and determine why.
More force isn't a substitute for the right technique or tool.
