Is this stuff safe to use on my chrome lined Bcm Bfh barrel? It seems to bust that carbon pretty darn good.

go through on big box 6 cans a week  all types of guns and barrels not one problem EVER my go to stuff...

So I can flush my barrel and gas tube (gas tube if needed) with this stuff and it will have no ill effects. Im sure its probably not good for the anodizing though on the receivers, right.

It's fine. Stop worrying.  Just be sued to lube everything again, including interior surfaces. The silent removes all lube and you need to replace it for rust prevention. It may cause some discoloration to the aluminum, but that ISF because it's just bone dry. Even if it strainer it, that's not the anodizing. Anodizing hardens the surface of the aluminum then it's dyed. As long as you don't remove the top layer of metal the anodizing is fine. Even if you set a lower in the sun for a year to bleach it.
