What's the best way you guys have found to get the carbon build up off the rear of the bolt? Scraping it is a pain in the ass but not sure what else to do...

I still have some get built up, but it comes off almost completely with a thumbnail.

I toss the bolt and carrier in a cheap Harbor Fright ultra sonic cleaner and let it run while I clean the rest on the rifle. After about 20-30 minutes soaking in the ultra sonic the carbon wipes right off. Only problem is I wish I would have done this years ago lol.

Most people these days use a dedicated carbon removal tool.

The two best ones seem to the the CAT 4 and the Otis BONE.
Both scrape the carbon off the rear "tail" of the bolt, out of the bolt carrier, and off the front side of the firing pin flange.
They do this quickly without any soaking or scrubbing, and will do it without damaging anything if used properly.
If you'd like to remove bolt and carrier carbon fast and without a lot of drama, this is the way to go.

I use breakfree clp, brass scraper tool and an all purpose brush.  I just scrape, soak, scrub and scrape some more until it is clean enough for me.  There are a few specific tools sold to clean the bolt tail if that is something you would be interested in.

Michigan71,

I just use oil and scrap or even use a beat up copper 22 brush. Doesn't take long to get it clean.

A $2, two inch brass wire wheel and a drill gets the carbon off the tail of the bolt.

An empty 308 cartridge and a spritz of Hoppes on the tails before to start is all you need to scrape it of and get it clean.

The dedicated tool from Brownells is good.  I have it because I am a little OCD.  However you also don;t really need to keep it that clean, get the chunks off, lube, drive on with life.

Why must any carbon build up be removed?

Cory Trapp from NSSF ways it is not necessary and has no effect on operation.   https://www.youtube.com/watch?v=xW4DQ5QlwrA

Be nice, I'm just asking.
