Maintaining Your AR 15 Upper: Cleaning and Care

Proper maintenance is essential to ensure the reliability and longevity of your AR-15 upper. Regular cleaning and care of the upper receiver, barrel, and related components will help keep your firearm in good working condition. Here’s a step-by-step guide on how to maintain your AR 15 Upper:

1. Safety First:

  • Ensure your firearm is unloaded and the magazine is removed before starting any maintenance.

2. Gather the Necessary Tools and Supplies:

  • Cleaning rod or bore snake.
  • Cleaning patches.
  • Bore brush.
  • Cleaning solvent or CLP (Cleaner, Lubricant, and Protectant).
  • Lubricating oil.
  • Nylon or brass brushes.
  • Cleaning rod guide (bore guide).
  • Cleaning rod or bore snake.
  • Microfiber cloth or cleaning patches.
  • Toothbrush or nylon brush for scrubbing.

3. Disassemble the Upper Receiver:

  • Remove the upper receiver from the lower receiver.
  • Separate the upper receiver components, including the bolt carrier group (BCG), charging handle, and handguard (if applicable).

4. Clean the Barrel:

  • Attach a bore brush or bore snake to the cleaning rod.
  • Run the bore brush or bore snake through the barrel multiple times to remove fouling and debris.
  • Follow up with cleaning patches soaked in cleaning solvent until they come out clean.

5. Clean the BCG:

  • Disassemble the BCG (remove the firing pin, cam pin, and bolt).
  • Wipe down all components with a clean cloth or patches.
  • Scrub carbon buildup from the bolt face, bolt lugs, and other areas using a toothbrush or nylon brush.
  • Apply cleaning solvent as needed to dissolve stubborn carbon deposits.
  • Lubricate the BCG with CLP or gun oil. Pay attention to the cam pin, firing pin, and bolt rings.

6. Clean the Upper Receiver:

  • Use a cleaning brush, patches, and cleaning solvent to clean the upper receiver’s interior and any hard-to-reach areas.
  • Pay attention to the feed ramps, ejection port, and gas tube area.
  • Wipe down and lubricate the charging handle.

7. Inspect and Lubricate:

  • Inspect all components for wear, damage, or signs of corrosion.
  • Apply a light coat of CLP or lubricating oil to all metal components, focusing on areas with metal-to-metal contact.
  • Avoid over-lubrication, as excess oil can attract dirt and fouling.

8. Reassemble and Function Test:

  • Reassemble the upper receiver components.
  • Perform a function test to ensure the upper functions properly, including chambering a round, firing, and cycling.

9. Exterior Cleaning:

  • Wipe down the exterior of the upper receiver and handguard with a microfiber cloth.
  • Pay attention to any areas with dirt, fouling, or fingerprints.

10. Store Properly: – When not in use, store your AR-15 upper in a dry and temperature-controlled environment.

11. Regular Inspections: – Periodically inspect and clean your upper receiver, even if it hasn’t been fired recently.

Regular maintenance is crucial to ensure the reliable performance of your AR-15 upper. The frequency of cleaning and maintenance will depend on how often you shoot and the environmental conditions in which you use your firearm. Following these steps will help keep your AR-15 upper in excellent condition for years to come.
