I use the G and G tool and the green scotch brite pads (the ones without the aluminum strands in them, from the 99 cents store). My bolt is a stag chrome plated, so if this treatment were damaging the metal i'd see it.
Here's the G & G tool, it is only $19.95. Half the cost of the CRT-15. You shove in the bolt tail, the round steel blade bears against the carbon. You then rotate the bolt, and the steel blade scrapes off the carbon. The steel blade is not very sharp at all, but it is contoured properly to fit the curve of the bolt tail. They sell spare blades but the one that comes with it is two sided, if you wear out one end there's another end to use. Also the G & G people sell what are basically scotch brite pads cut into strips, for final finishing. I just buy a 3 pack of the pads at the store and cut them into 2 inch wide strips, and it is the same thing.

Here's pictures of my chrome plated bolt after 1000 rounds, is there any chance i am damaging it?

That wouldn't surprise me - you're probably right, i may have scraped the chrome plate off. The chroming was not exactly top notch i don't think, I can't remember seeing chrome plating that wasn't SHINY.
I also have a titanium plated cam pin, i should have taken a picture of that too; the plating was totally gone, worn off from the part of the cam pin where it wears in the classic swirl pattern, after 100 rounds.
I have thought of getting the "Fail zero" parts but they are very pricey for the problem they are supposed to solve. Honestly if I had known how dirty the DI AR's get, and what a PITA to properly clean (dirty guns really bug me - yes, I have some kind of weird OCD, my apartments a mess but all my guns are spotless...)
Not to turn this into a piston gun post but allow me to stray a bit off topic for a minute....i wish i had bought the Stag 8 piston AR, it was less then $200 more at the same gun store. No worries about scraping bolts or carriers, just the piston. Some pics...i wonder how much they'd sell a conversion kit probably a lot...

Piston and rod replaces gas tube
The bolt carrier...Stag claims the design eliminates bolt tilt.

I should've been more clear in my post. The idea it is self limiting has been put out there for a while now and I have come to agree with it for the most part. I dont think there is a specific point at which it no longer builds or that it no longer will at all, just that it doesn't go beyond the functional threshold. From my own observation of what little sample size I have of personal weapons and those from others I have handled, including a couple of high round count LE carbines... I have never seen carbon build up enough to affect function. My non-scientific take on it is, some of it gets blown off and becomes part of the loose gunk you can easily wipe off.
Boresnake, BCG wipedown, Slip2000 and 5 minutes is all it should take to 'clean' a carbine IMO.
Buildup is a sign you're using your rifle...which I view as a goooood thing
Waste of money IMO. The scraper does nothing a spent casing wont. In either case, it's a waste of time.
There's never a reason to clean to the point of removing a finish/surface treatment.
IDK if the phrases "I wish I had bought" and "Stag" will ever cross my sober mind. Dumping a proven system for a shitty brand just because it 'runs cleaner'...this may be the wrong forum for that mindset. Just sayin.
