Frequently Asked Questions

What are the essential safety steps before cleaning an AR-15?

Always ensure the firearm is unloaded. Use a chamber flag to visually confirm the chamber is empty. Work in a well-ventilated area and be mindful of your surroundings.

How do you properly clean the Bolt Carrier Group (BCG) of an AR-15?

Disassemble the BCG, removing the firing pin, cam pin, and bolt. Soak components in solvent, then wipe away carbon. Inspect parts for wear and ensure gas rings are properly gapped and staggered.

What tools are recommended for AR-15 bore cleaning?

A bore guide is highly recommended to protect the rifling. Use a one-piece stainless steel cleaning rod with a suitable brush and patches, along with a quality bore solvent.

How should the trigger group be cleaned on an AR-15?

Jerry Miculek advises against frequent trigger disassembly. Instead, use contact cleaner or brake parts cleaner to flush out the trigger group, ensuring solvent compatibility with the firearm's finish.
