How to remove carbon buildup on cage crown

I got some carbon buildup (or something similar) on the muzzle crown of my new stainless barreled AR-15. This appears to be blowback from using a thread adapter.

It is not coming off using Q-tips or terry cloth, fifty-fifty when the crown has been soaked in Breakfree/CLP for over 6 hours.

I tried a soft toothbrush likewise and nothing is coming off.

Any suggestions for removal brusque of using a small, fine brass bristle castor? Do you call back that would harm the crown?

I'd try a file and a bench grinder. Merely kidding.

How about a niggling stronger solvent and a coarse fabric. I personally wouldn't be above a niggling gentle 0000 steel wool. I suspect some would disagree, though.

I had the same trouble with my SWR Warlock. Crap would build up on the muzzel and was very hard. I finally got tired of looking at it and cleaned information technology off with Hoppes solvent and elbow grease. Now, I just wipe on some Hoppes and it comes right off. I attempt and exercise this everytime I shoot now. The start cleaning was tough!

Your elbows must be stronger than mine! I tin can't become it off at all except for 1mm correct effectually the bore. I am going to try the pb removing stuff next.

If this happened in a suppressor, does it mean that the boom bamboozle was too close to the muzzle?

Information technology doesn't seem that this should happen since I'yard sure that accuracy would be affected over the long haul.

Information technology's carbon not lead. I use a sanding block on the bolt of my m16. Become some Slip2000. Make certain to follow the directions on the bottle, once y'all open up it, it will eat its own bottle.

Every ar15 I have does this, esp nether the wink hider. I don't really shoot for accuracy, so I just scrape it off.

I use a dental option or a small screwdriver and advisedly scrape it off. It takes some fourth dimension just it is the only thing I have found that works.

Hey, I'm new to this site, but have dealt with your trouble earlier. The very best carbon remover available is GM Top Engine Cleaner. I shoot LR with a 300 winmag which builds up a lot of carbon in the throat. One of the acme LR shooters in the country turned me on to the stuff. It will remove what nothing else volition, it is totally safe on firearms and is pretty inexpensive too.

Are any of these carbon removers safe on aluminum suppressors?

Also, AAC recommends laquer thinner, is this as effective as slip2000 for carbon?
