Copper fouling is a common problem for firearms, especially those that are used frequently or for extended periods. While copper fouling can occur in any part of the gun, it is most commonly found in the barrel, bolt, and bipod.
Copper fouling can lead to several problems, including decreased accuracy and increased wear on parts. It’s important to clean your gun regularly to remove any copper fouling.
There are some ways to remove copper fouling, but the most effective method will vary depending on the type and extent of the fouling. If you feel uncertain about how to safely and effectively remove copper fouling from your gun, consult a professional gunsmith or cleaning service.

Barrel
AR-15 barrel copper fouling occurs when the copper from the bullets accumulates in the barrel. This can happen after just a few shots, and if left unchecked, it can lead to decreased accuracy and increased wear on the barrel.
There are different ways to remove copper fouling from an AR-15 barrel, but the most effective is to use a bore brush and cleaning solvent.
Here’s how to clean the AR-15 barrel:
- Disassemble the AR-15 and remove the bolt carrier group.
- Using a bore brush and cleaning solvent, scrub the inside of the barrel until all of the copper fouling has been removed.
- Once the barrel is clean, reassemble the AR-15 and you’re ready to shoot again.
Bolt
AR-15 bolt copper fouling is a problem that can occur after extended use of the rifle. The AR-15 platform uses a gas impingement system, which means that hot gases are used to cycle the action.
Over time, these hot gases can build up on the bolt carrier group and cause copper deposits to form.
These deposits can lead to increased wear and tear on the bolt and carrier and can cause the rifle to malfunction.
Important to note that copper fouling is not unique to the AR-15, and can occur in many firearms, including those that use a similar gas impingement system. To prevent this problem, it is important to regularly clean the AR-15 and to use quality lubricants.
Here’s how to clean the AR-15 bolt:
To clean the AR-15 bolt, you will need a cleaning solvent, a bore brush and a rag.
- Disassemble the bolt carrier group and remove the bolt.
- Spray the bolt with a cleaning solvent and scrub it with a bore brush until all of the copper fouling has been removed.
- Wipe down the bolt with a rag to remove any residual solvent.
- Reassemble the bolt carrier group and you’re ready to go.
Bipod
AR-15 Bipod copper fouling is a common issue that can affect the performance of your rifle. There are a few things you can do to help prevent this.
First, make sure that you clean your AR-15 Bipod regularly. This will help to remove any build-up of copper that could potentially cause problems.
Second, consider using a different type of ammunition. Copper-jacketed bullets are more prone to cause fouling.
Finally, keep your AR-15 Bipod well lubricated. This will help to reduce friction and prevent copper buildup.
Here’s how to clean the bipod:
- Disassemble the bipod and remove the screws.
- Spray the bipod with a cleaning solvent and scrub it with a bore brush until all of the copper fouling has been removed.
- Wipe down the bipod with a rag to remove any residual solvent.
- Reassemble the bipod and you’re ready to go.
