Frequently Asked Questions

What are the essential steps for cleaning an AR-15?

Begin by ensuring the firearm is unloaded. Separate the upper and lower receivers, remove the bolt carrier group (BCG) and charging handle, then disassemble the BCG. Clean all components thoroughly, paying attention to the star chamber, and finally clean the barrel using solvent, a bore brush, and dry patches until clean.

What tools are recommended for cleaning an AR-15?

Specialized tools like Otis cleaning brushes and flexible cleaning cables are highly recommended for reaching difficult areas. A punch may be useful for take-down pins, but care should be taken not to scratch the finish.

Why is cleaning the bolt carrier group (BCG) important for an AR-15?

The BCG is critical for the AR-15's function. Cleaning it ensures proper chambering of rounds and ejection of spent casings, preventing malfunctions and maintaining reliable operation. It houses key components like the firing pin and extractor.

How should the barrel of an AR-15 be cleaned?

Clean the barrel in three stages: first, use a wet patch with solvent to loosen fouling. Second, employ a bore brush to scrub away debris. Finally, run dry patches through the bore until they come out clean, repeating as necessary.
