How to Clean Your AR-15 — Three Good AR Maintenance Videos

Let’s face it, AR-platform rifles run dirty, at least compared to typical bolt-action rifles. The AR-15 works by piping gas from the barrel back into the bolt carrier, causing the bolt to unlock and the carrier to move the bolt backward. The “exhaust gas” from the barrel contains soot and carbon. The carbon will form hard deposits on the bolt. In addition, the carbon can combine with lube on the bolt carrier to make a nasty, paste-like sludge. This can be particularly problematic when the black paste pollutes the ejector and extractor recess.

This Editor has inspected dozens of ARs over the years. Other than mag-related malfunctions, the most common cause of AR cycling problems I found was oily gunk in the extractor and ejector areas. Many AR owners overlook these critical areas. Look at an AR that hasn’t been cleaned properly and you’ll probably find black gunk (and small brass shavings) in the ejector and extractor recesses.

If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here are three videos that explain how to properly disassemble and clean AR-platform rifles. And then they cover the essential lubrication ARs need to run reliably.

Take-Down and Full Cleaning of AR15 by Jerry Miculek

Here ace shooter Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.

General AR-15 Maintenance and Lubrication

There are various schools of thought on AR lubrication. Some guys like to run “wet” with lots of CLP, while others choose to focus lubrication on the key spots that receive the most friction and wear, such as the contact point for the bolt carrier. We do advice check the ejector recess and extractor spring recess frequently as gunk can get in there, causing malfunctions. Here is a good video from Pew Pew Tactical — a 7-minute guide to cleaning and lubricating AR-platform rifles. This shows important details for both the upper and the lower.

How to Clean Your AR-15 Bolt Carrier Assembly

This video offers very specific advice on the bolt carrier group, which receives the dirty gas directly from the barrel. Be sure to check the extractor and ejector recesses. That’s where old lube, brass shavings, and carbon accumulate. Follow the directions in this video for lubrication, and don’t over-lubricate the bolt carrier — that will only capture more carbon.
