How to Clean and Maintain AR-Platform Rifles — Tips and Videos

Barrel cleaning AR15 bolt carrier carbon Jerry Miculek gas key direct impingement

AR-platform rifles can be maintenance-intensive beasts. But some AR owners make the situation worse by not regularly cleaning important small parts, or by using too much oily/greasy lubricants in the wrong places. A properly maintained and lubricated AR15 can shoot hundreds of rounds (between cleanings) without a problem. If you learn where (and where not) to apply lubricant, you’ll find that your AR will run more reliably and the task of cleaning the bolt and bolt carrier will be less of a burden.

Here is a good video that explains AR-15 Cleaning and Maintenance. In this 30-minute NSSF video, Gunsite Academy instructor and gunsmith Cory Trapp discusses the proper way to clean and maintain the AR-15 carbine. Very knowledgeable, Trapp provides rock-solid advice for AR owners. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.

AR Service Rifle Trigger Technique — Good Advice from USAMU

ar service rifle ar15 trigger control

The First Shot, the CMP’s archived Online magazine, has an article by Spc. Tyrel Cooper of the U.S. Army Marksmanship Unit (USAMU). In his article, Straight to the Rear, Spc. Cooper describes proper trigger hand and finger positions and how to best “break the shot”. This well-written article will help anyone who shoots off-hand, or who uses an AR or Spacegun-type rifle with a vertical pistol grip.

Cooper explains: “Trigger control is one of the two main principles of shooting that we teach. You can have the best position in the world with perfect sight alignment, but if you have bad trigger control, you have wasted all that effort that you put into your position and sight alignment.”

Firing Hand Position and Finger Placement
“Good trigger control begins with a good firing hand position. Place your firing hand high on the pistol grip, with a good firm grip. Grip tension should be like giving someone a hand shake or holding a child’s hand while walking across a street. A good firm grip [helps you] move your trigger finger without moving your other fingers. Try this, hold out your firing hand with fingers extended; now try moving your trigger finger to the rear as if you were pulling the trigger. Unless you concentrate very hard on moving just your trigger finger, other fingers will move. Now make a fist as if you were grabbing a pistol grip, now you can move your trigger finger freely without introducing movement in the other fingers.”

service rifle shooting AR-15 AR trigger technique USAMU

“I’m sure you have heard advice to place the tip or the pad of your finger on the trigger. This is true if you have short stubby fingers and that’s where the index finger naturally rests, but if you have long fingers like myself you want more of your finger around the trigger…. By placing your finger where it naturally rests on the trigger you are ensuring that you are pulling the trigger straight to the rear, and this also allows you to get more leverage on the trigger.”

Rapid-Fire Trigger Technique
“Trigger control for the rapid-fire stage is different than it is for standing. You can actually take a little bit more time to break your shots in rapid fire because of the steadiness of a supported position. A good rapid fire shot process is: 1) drop down into position, 2) get your natural point of aim, 3) take up the first stage on your first shot, 4) break that shot smoothly and hold the trigger all the way to the rear through recoil, 4) once recoil has ceased, let the trigger out only far enough to reset the trigger (you should hear a metallic click of the trigger resetting) and continue by firing your second and succeeding shots.

By doing this, you already have most of the weight of the trigger taken up so the next shot is ready to go without having to take up all the weight of the trigger every single shot.”

Slow-Fire Prone Technique
“During the slow fire prone stage, you have even more time to break your shots, so you would use the slow–smooth method. You should have little or no hold movement at all, thus allowing you to acquire good sight alignment, a good sight picture and break the shot using slow and smooth trigger control. Again you want to hold that trigger all the way to the rear until recoil has ceased so you do not disturb the rifle, no matter what position you are shooting.”

Standing Trigger Technique
“When you are shooting standing have you noticed that the rifle never really stops moving? Well, this is where you would want fast and smooth trigger control. When I come down and start settling on the target, I take up the first stage of the trigger. Once I’m getting to the end of my firing process and the movement has slowed down, I manipulate the trigger fast, but smooth, to the rear when I see what I want to see in my sight picture. Over time, this will become a subconscious act; when your brain sees the sight picture, it will automatically tell your trigger finger to move instead of you having to tell yourself there it is, take it. Lots and lots of dry firing will help this process. To repeat, you want to be fast and smooth!”

How to Clean and Maintain AR-Platform Rifles — Helpful Videos

AR15 AR AR-15 MSR black rifle cleaning maintenance bolt lubrication
Scottsdale Gun Club offers an AR-15 Cleaning Clinic on August 25, 2022.

AR-platform rifles can be maintenance-intensive beasts. They need regular inspection, cleaning, and lubrication. But some AR owners make the situation worse by not regularly cleaning important small parts, or by using too MUCH oily/greasy lubricants in the wrong places. A properly maintained and lubricated AR15 can shoot hundreds of rounds (between cleanings) without a problem. If you learn where (and where not) to apply lubricant, you’ll find that your AR will run more reliably and the task of cleaning the bolt, bolt carrier, and upper receiver internals will be less of a burden.

Here we showcase videos that show how to field-strip an AR-15, inspect the key parts, clean components, and lubricate internal parts as needed. Along with these videos, we recommend you read the comprehensive AR-15 Gun Cleaning Clinic article on the Brownells website. This explains in detail important procedures that the videos might only cover in a few seconds.

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 five videos that explain how to properly disassemble and clean AR-platform rifles.

AR15 AR-15 AR bolt carrier cleaning videos

1. How To Clean Your AR-15 | Cleaning and Maintenance Tips

This is a quick 90-second starter video that may help new AR owners. Ricky Lehnhardt of OTIS Technology demonstrates the basics of cleaning and maintaining your AR-15. Lehnhardt does a good job identifying the points that need cleaning on the inside of ARs. However he works very quickly in the video. You may want to pause the video at some points. Also, Lehnhardt employs a cable for pulling patches and brushes through the barrel. Yes this is fast and easy. However, for match AR rifles, we recommend that you instead use a cleaning ROD with fitted bore guide.

2. Take-Down and Full Cleaning of AR-15 by Jerry Miculek

Gunsite Academy instructor and gunsmith Cory Trapp demonstrates the proper way to field-strip, clean, and lubricate an AR-15 carbine. In this 30-minute video, Trapp offers several important technical tips and hints. For example, at 11:05 Trap demonstrates how to determine if your bolt needs new gas rings. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.

4. AR-15 Dissassembly and Cleaning Guide

This video does a good job, with close-ups, showing how to remove the bolt carrier and clean the inside of the upper receiver. Then you can see how to work with various tools to clean the bolt, bolt carrier, and inside of chamber. We also recommend that you inspect the ejector recess and extractor recess. When we’ve inspected ARs that failed to cycle properly, we have often found nasty gunk (mixture of carbon, greasy lube, and brass particles) in these areas.

5. Basic AR-15 Quick and Easy Field Maintenance

In this NSSF-sponsored video, pro shooter Ryan Muller demonstrates basic, quick field maintenance of his AR-15. This would be for a quick cleaning and lubrication of the reciprocating parts. This covers rapid maintenance in the field. For full field-stripping and thorough cleaning, watch the previous videos.



Handy Mat for Cleaning AR Rifles

When working on an AR-15, it’s smart to have a pad that can absorb solvents and cushion your upper and lower. The $24.99 Real Avid Smart Mat is a good choice. This features printed take-down instructions and it has a handy parts tray on the right side. The mat rolls up for convenient storage. Click HERE to learn more.

Good Guide to Take-Down and Maintenance of AR Bolts

AR15 Bolt Disassembly

Accurate, modular, and supremely versatile, the AR15 is America’s favorite semi-auto rifle. But let’s face it, the AR is a maintenance hog. The AR’s gas tube blows carbon and soot right into the middle of the bolt assembly where it cakes on to the metal. The AR bolt also has many tiny parts, and small recesses, which must be cleaned regularly. This author has seen numerous ARs fail simply because there was gunk (dried lube, carbon, brass shavings) in the ejector slot or extractor spring recess.

A Clean AR is a Happy AR — Whether You Run ‘Wet’ or ‘Dry’
There are various schools of thought when it comes to maintaining an AR. Some folks prefer to run their AR “dry” with minimal lube on the lugs and friction surfaces. Other shooters prefer to run their ARs “wet”, with lots of lube. But whatever your preference, you need to clean your AR regularly. And nothing is more important than the AR’s bolt/carrier assembly. Because it is involved in feeding, firing, and extracting, the AR-15 bolt/carrier assembly can be considered the most critical portion of the AR-15 from a maintenance standpoint.

Bolt Take-Down Guide on Top Quark Blog
The editor of the Top Quark Blog has created an excellent illustrated AR15 Bolt Take-Down Guide that shows how to disassemble an AR15 bolt and carrier for regular cleaning. Even if you’re an experienced AR15 shooter, you can learn something from this page (sample at right), and you may want to bookmark it for future reference. The photos are large and clear and there are helpful hints for each step of the process.

The author knows his stuff and offers some important insights. For example, he notes that “Extractor springs in most AR15 bolt assemblies are fairly weak, and this can lead to various extraction-related failures. One of the few high points about Colt assemblies is their usage of higher-strength extractor springs. You can tell the difference by looking at the inner plastic insert. ‘Normal’ springs feature a blue plastic insert, Colt strong springs have a black insert.”

There is one notable oversight on this page — the author doesn’t cover disassembly and cleaning of the ejector assembly. This is actually quite important. A few small brass shavings, combined with carbon and lube in the ejector slot, WILL cause malfunctions. In fact, when this editor is called to diagnose problem ARs, the first things I look at (after swapping magazines) are the ejector recess and the slot for the extractor. Clogged ejectors are responsible for fail-to-ejects and other jams. It is essential that you keep the ejector hole clean. Old, gooey lube residues mixed with carbon and tiny brass shavings in the ejector recess will create all sorts of problems. As shown in the diagram below, it is simple to remove the ejector (#6) and ejector spring (#5), by drifting the ejector retaining pin (#4).

AR-Platform Rifle Cleaning Advice

AR15 cleaning procedure

AR-platform rifles run dirty — very dirty. The gas system blows carbon and powder residues back into the action and into the bolt carrier group. That’s why you need to clean your ARs regularly, and you have to pay special attention to the nooks and crannies in the bolt and bolt carrer. The majority of AR failures we’ve witnessed have been from a combination of lube, carbon, and tiny brass shavings that collected in the ejector recess and the extractor spring recess. After that, plain carbon build-up on the bolt can be a gun-stopper too. And you need to keep the barrel extension clean too.

If you’re new to the (dirty) world of ARs, here are two helpful videos from the folks who make Froglube. That line of cleaners/lubes is pretty good stuff, though not our first choice for all AR lubrication and cleaning chores. But these videos do provide many helpful tips. They show the disassembly process and highlight the problem areas to which you must pay special attention.

NOTE: Froglube also makes a video showing AR upper, chamber, and barrel cleaning. There are practices shown there that we do NOT recommend. Nor do we recommend Froglube products for bore cleaning. We think there are more effective cleaning products.

2. Take-Down and Full Cleaning of AR-15 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.

3. AR-15 Maintenance: Field-strip, Clean and Lubricate an AR-15

Gunsite Academy instructor and gunsmith Cory Trapp demonstrates the proper way to field-strip, clean, and lubricate an AR-15 carbine. In this 30-minute video, Trapp offers several important technical tips and hints. For example, at 11:05 Trap demonstrates how to determine if your bolt needs new gas rings. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.

4. AR-15 Dissassembly and Cleaning Guide

This video does a good job, with close-ups, showing how to remove the bolt carrier and clean the inside of the upper receiver. Then you can see how to work with various tools to clean the bolt, bolt carrier, and inside of chamber. We also recommend that you inspect the ejector recess and extractor recess. When we’ve inspected ARs that failed to cycle properly, we have often found nasty gunk (mixture of carbon, greasy lube, and brass particles) in these areas.

5. Basic AR-15 Quick and Easy Field Maintenance

In this NSSF-sponsored video, pro shooter Ryan Muller demonstrates basic, quick field maintenance of his AR-15. This would be for a quick cleaning and lubrication of the reciprocating parts. This covers rapid maintenance in the field. For full field-stripping and thorough cleaning, watch the previous videos.



Handy Mat for Cleaning AR Rifles

When working on an AR-15, it’s smart to have a pad that can absorb solvents and cushion your upper and lower. The $24.99 Real Avid Smart Mat is a good choice. This features printed take-down instructions and it has a handy parts tray on the right side. The mat rolls up for convenient storage. Click HERE to learn more.

TECH TIP: How to Take-Down and Maintain Your AR Bolt

AR15 Bolt Disassembly

Accurate, modular, and supremely versatile, the AR15 is America’s favorite semi-auto rifle. But let’s face it, the AR is a maintenance hog. The AR’s gas tube blows carbon and soot right into the middle of the bolt assembly where it cakes on to the metal. The AR bolt also has many tiny parts, and small recesses, which must be cleaned regularly. This author has seen numerous ARs fail simply because there was gunk (dried lube, carbon, brass shavings) in the ejector slot or extractor spring recess.

A Clean AR is a Happy AR — Whether You Run ‘Wet’ or ‘Dry’
There are various schools of thought when it comes to maintaining an AR. Some folks prefer to run their AR “dry” with minimal lube on the lugs and friction surfaces. Other shooters prefer to run their ARs “wet”, with lots of lube. But whatever your preference, you need to clean your AR regularly. And nothing is more important than the AR’s bolt/carrier assembly. Because it is involved in feeding, firing, and extracting, the AR-15 bolt/carrier assembly can be considered the most critical portion of the AR-15 from a maintenance standpoint.

Bolt Take-Down Guide on Top Quark Blog
The editor of the Top Quark Blog has created an excellent illustrated AR15 Bolt Take-Down Guide that shows how to disassemble an AR15 bolt and carrier for regular cleaning. Even if you’re an experienced AR15 shooter, you can learn something from this page (sample at right), and you may want to bookmark it for future reference. The photos are large and clear and there are helpful hints for each step of the process.

The author knows his stuff and offers some important insights. For example, he notes that “Extractor springs in most AR15 bolt assemblies are fairly weak, and this can lead to various extraction-related failures. One of the few high points about Colt assemblies is their usage of higher-strength extractor springs. You can tell the difference by looking at the inner plastic insert. ‘Normal’ springs feature a blue plastic insert, Colt strong springs have a black insert.”

There is one notable oversight on this page — the author doesn’t cover disassembly and cleaning of the ejector assembly. This is actually quite important. A few small brass shavings, combined with carbon and lube in the ejector slot, WILL cause malfunctions. In fact, when this editor is called to diagnose problem ARs, the first things I look at (after swapping magazines) are the ejector recess and the slot for the extractor. Clogged ejectors are responsible for fail-to-ejects and other jams. It is essential that you keep the ejector hole clean. Old, gooey lube residues mixed with carbon and tiny brass shavings in the ejector recess will create all sorts of problems. As shown in the diagram below, it is simple to remove the ejector (#6) and ejector spring (#5), by drifting the ejector retaining pin (#4).
