Don't scrape it with anything harder than brass

Would you carve metal off your internal combustion engines chamber ?

In boot camp (recruit training) they had us scrape the carbon off the bolt with the firing pin.  

Also used the firing pin to scrape the crown of the muzzle and we also took them into the showers to clean them before final inspection.

Why?

The bolt will break long before carbon build up becomes an issue.

I no longer scrape the carbon from my bolt tail. I let it sit in some Hoppes and then scrub it with a brass brush a few times and call it good to go. Whatever is left on there, is left on there. About 15k rounds on my particular rifle at this point, mostly from 500 to 1000 round training days. YMMV.

I've never scraped the carrier or bolt tail on an AR. I sure as shit wouldn't do anything to the BCG involving a Dremel.

I have a BONE tool that I use, if there is not enough buildup to matter it does nothing, bolt is not spotless but functional.
Think of how stupid the average person is and realize half of them are stupider than that.

And "they" were idiots. Would recommend completely forgetting what "they" told you about the topic.

I recently took a milspec bolt with a lot of hard caked carbon on the back, soaked the tail in breakthrough suppressor clean in a shot glass for a couple days, and 99% of it wiped right off with a rag in literally about 2 seconds.

I would never scrape it with anything... ymmv.

Eugene actually designed the firing pin to also be used as a scraper tool.
Not just the end of the firing pin in the carrier.

But the other end also to fit the curves on the bolt itself.
You just gotta be smarter than the average national park bear to see how it can be used....

Carburetor spray made for carbon cleaning.  Dremel seems drastic.  Soak it and let it set, don't  get In a hurry for results.

Just buy a lot of bolts. When 5 get dirty put in a container and spray with brake cleaner until shiny. Take them out and lube them.

Except for the tail of the bolt. That gets scraped with a pocket knife.

That's the worst thing you can do, and you are ruining the bolt tail.
