Let’s face it, AR-platform rifles run dirty, at least compared to typical bolt-action rifles. The AR15 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.
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.
How to Clean Your AR-Platform Rifle
This is a good basic video that shows the take-down and cleaning procedure for a typical AR15. It uses some fast-motion sequences to speed up the story. Check out this video if you don’t have the time to sit through the Miculek video above.
Cleaning and Lubricating AR15 Bolt Carrier Group
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.

If you’ve been following the tactical message boards, you’ll hear a lot of buzz about FrogLube CLP. Among the zillions of gun cleaner/lubes on the market, FrogLube stands out for its ability to work well even in challenging environments. Intended for U.S. Navy SEAL operators’ use in extreme environments, FrogLube was developed by Larry Lasky (Captain, USN retired), a former Navy SEAL officer. FrogLube’s blend of ingredients has been extensively field tested. The makers of FrogLube claim that fouling is dramatically reduced in FrogLube-treated firearms. FrogLube is a decent carbon-cutter and it also provides protection against rust and corrosion (though there are better rust preventers on the market, such as Eezox).
NOTE: Don’t expect FrogLube to remove copper fouling in the barrel — you’ll need a real copper solvent, such as Montana X-Treme. Overall, though, as a general purpose CLP, FrogLube performs well.
FrogLube is now available from major vendors, including Amazon.com and MidwayUSA. Notably, FrogLube is a “green” product that has received the USDA’s BioPreferred designation. On Amazon.com, a 5-piece combo kit with CLP liquid, CLP paste FrogLube, and FrogLube Solvent sells for $30.95 with FREE Shipping (on orders over $35). Amazon’s customers have raved about this stuff:
I was introduced to this product by a Sig armorer. I tried it. I loved it. It works. Period. Just like everyone else is saying here. Here is my break down of it as a CLP. The “C”: I have found that putting it on warm metal makes it work great…just like they say. I rub the paste on, let it sit and penetrate. A few minutes later….wipe it off. Clean enough to eat on. I even tried it on my mountain bike chain and components after running out of degreaser. Worked better than anything I have ever tried. The “L”: Once you use it on the parts you will notice it’s still there, having saturated the parts. Great for lube and goes a long way. The “P”: I hunt waterfowl in very rugged and sloppy conditions. The thing about this product is that when they say it saturates the metal, it truly does. Great protective features. It’s still on there and after all that moisture not speck of rust anywhere, unlike even the best of of other CLPs. — J. Zabick
Crazy Good — This stuff is amazing. I use it on my knives, razors and, of course, guns. It smells great, leaves no oily residue and cleans like nothing else I have used. Get the paste and the oil because sometimes the oil is called for and sometimes you need the paste. Can’t recommend it enough. I have already ordered more. — K. Chariton

What anti-corrosion products really fight rust effectively? You’ll hear many opinions, but what do actual field tests reveal? One rifle shooter, who posts on YouTube as BlueonGoldZ, wanted to separate myth (and marketing claims) from reality, so he completed his own long-term rust test using metal samples. First he used ordinary tap water spray, and then he did a second, longer-duration test with a salt-spray solution. Nine different products were tested: Break Free CLP, Corrosion-X, Frog Lube, M-Pro 7, Outers, Pro-Shot Zero Friction, Rem Oil, Slip 2000, and Tetra Gun Triple Action CLP.
BlueonGoldZ initially examined each product for its “beading” properties with a normal tap water spray. But the main test involved many multiple weeks of exposure after a “dense” salt-water spray. (No rust formed after two weeks tap water exposure, so the test was accelerated with salt-water exposure).
The clear winners in the test, as shown by the screen shot above, were Corrosion-X (Best), and Frog-Lube (Second Best). The photo shows the test samples two weeks after being sprayed with salt water. The results are pretty dramatic — you can see with your own eyes what happened. We think this is a very useful bit of real-world research.
Results from Similar Long-Term Salt Exposure Test
Unfortunately, BlueonGoldZ’s test did NOT include Eezox, which we have found to be extremely effective (on a par with Corrosion-X). In another long-term test of corrosion preventatives, the two best rust fighters were Eezox and Corrosion-X in that order. Since that test was completed, Corrosion-X, already an excellent product, has been enhanced. CLICK HERE for Long-Term Salt Exposure Test Report.
