Frequently Asked Questions

What are the essential tools for cleaning a dirty AR-15?

For a heavily fouled AR-15, essential cleaning tools include a good CLP like Radco CLP, T-shirt rags for wiping, a popsicle stick for scraping, a skewer for tight spots, and a toothbrush for stubborn grime. A large bore brush can also be helpful for the upper receiver.

How often should an AR-15 be cleaned?

While daily or frequent cleaning is ideal, this video shows a Cobalt Kinetics AR-15 running reliably after an estimated 7,000-8,000 rounds without cleaning. The instructor suggests cleaning when it's needed or when time permits, emphasizing that the rifle still functions as long as it's lubed.

What are the critical components to inspect on an AR-15 bolt carrier group?

When cleaning an AR-15 bolt carrier group, it's crucial to inspect the firing pin for tip damage, the cam pin for cracks (especially around the firing pin hole), and the bolt itself for cracks, particularly around the cam pin hole. Also check the gas rings for breaks or missing pieces.

How does Radco CLP help in cleaning a dirty AR-15?

Radco CLP is effective for cleaning a dirty AR-15 because it breaks down carbon buildup on components like the bolt carrier group and bolt. This allows for easier removal of fouling with simple tools like rags and popsicle sticks, making the cleaning process more efficient.

What is the correct orientation for the bolt carrier group extractor during reassembly?

During AR-15 bolt carrier group reassembly, it is critical to ensure the extractor is oriented towards the ejection port. This ensures that spent casings are properly ejected from the firearm after firing, preventing malfunctions.
