My brother fired his new AR-15 with the boresight device in the muzzle (forgot to take it out). :banghead: It will not shoot accurately and the last 3 inches of the bore is completely black with what looks like a serious layer of burn residue. He's run the brush down it with cleaner a number of times, but it is not clearing up the blackened bore. What are his options? Can he attach a bore brush/rod to a cordless drill and spin the brush where the damage is? Does he need to just get a new barrel?

Yes, feel fortunate that no one was hurt and put on a new barrel.

The barrel is bulged, not just dirty. Lucky it didn't blow the end right off the barrel.
Replace it.
I bought a Remington 788 .223 that turned out to have such a bulge. (I wondered why the seller would put out a dirty gun at a gun show, but dismissed it because the gun and price were attractive.) Even cutting the barrel off behind the bulge and recrowning did not restore accuracy, it took a new barrel.

On the up side, the marks left on the boresight will buff right out.

Cut barrel and recrown?
Might be able to cut the bulge part out and re crown.
Make sure you keep it over legal length.
A new barrel might be less costly in the long run.

It's not real expensive to rebarrel an Ar-15. You have no idea what other damage in the form of cracks are lurking unseen. Do it right and rebarrel. It's your safety at stake and it should be worth the bucks for the barrel replacement.

New barrel.
Hang the old one over your brothers workbench with a plaque "Darwin Award"
Eventually he will remember that as a "priceless" memory.

Not out of the question in our nanny-state environment. At least most gun owners bear a conservative label, as a more liberal type would consider a product liability suit against the bore sight manufacturer.
And probably prevail.
Alas, there are no laws against being stupid.

"...New brother..." OP brother's rifle. A lot of pointing and laughing comes to mind.
"...more liberal type would..." And lose at great expense. Frivoulous law suits are being thrown out these days. Even Stateside.
"...would complain they did not..." Bore sighters aren't small tools. Idiots get no sympathy.
No amount nor method of cleaning is going to fix a barrel that was fired with an obstruction.
