The inside of my bolt carrier has carbon build up. Not enough to cause problems with the bolt travel or firing pin movement. But I can't get all of the carbon out.

Is it important to clean off all the carbon deposits from inside the bolt carrier? (most of the build up is towards the back)

If it is, how do you get it all out?

I also use a 45-70 bore brush and put it in my cordless drill to get the majority out after soaking it overnight in Hoppe's. Then it is back to scraping the bottom of the bolt out...

I DON'T.


Per Armalite - Carbon in the AR15 is self limiting and will break off when it builds up.


I sold my carbon scraper years and 10's of thousands of rounds ago. I don't scrape anymore, and my guns run 100%

Same here, 100% in all my ARs and I never touch the carbon...

Thanks for the cleaning and tool advice. I never noticed that Bushmaster sold a tool for that purpose. I think I might get one.

But I like this advice most of all. I was hoping some one would tell me something like this.
I like the idea of more shooting and less cleaning.

Has anyone had a problem with this way of doing it?

I don't think scraping really makes a difference. You'll notice that the carbon cannot build past a certain point; it's essentially self-limiting. And I've never heard of corrosion ever forming under the carbon. Keep it well lubed with a good CLP like the manual says, clean it every time you shoot it, and you won't have a problem.

Don't worry - be happy!

Carbon draws in mostiure. If you dont oil it it will pit the bolt.

You dont need to scrape it off, just hit it with the gi brush and some clp. Anything more is not really needed.

I wipe off the carbon buildup on the rear of the bolt itself.

I tried my best using a patch to clean out the inside of the carrier.

The military teaches to use the brass part of an old stripper clip to scrape the carbon off. It works pretty good but I dont get carried away with it.

Only time I scrape carbon is for the Army.
They could care less if you turn the weapon in dry, but the better not be any carbon in it...

I wonder if Wipe-Out would cut the carbon?

Again, why bother?

because you can.

Just last night I spend a half hour cleaning my bolt and carrier to a gleaming shine with CLP, pipe cleaners, a knife blade for carbon, and a pistol cleaning rod with patches. Now after reading everyone I can't believe I didn't have to do that at all. Thanks for the info! No more cleaning other than wiping with CLP.

When I scraped carbon I usually just ended up taking a little finish off the bolt.


No thanks. Runs 100% without scraping.


I'm sure my Corvette's engine has some carbon in the cylinder walls, but I'm not scraping that either. I just take good care of her and enjoy the 350hp.

Have you tried Slip 2000 carbon Cutter yet? Drop the bolt and bolt carrier into this stuff fo 5 to 15 min. and the carbon just wipes off. NO brushing or scraping. Small Arms Review just had an story about it. You can look it up on there web site also. www.slip2000.com
