How do you get this crap off

As stated by a highly esteemed member of the Colt Forum, Dfariswheel...

To remove the carbon from the front of the cylinder, the fastest AND safest method is to buy a "Lead-Away" type cloth at the gun store.

This is a yellow cloth that removes the burn rings NOW, and without risking damage to the gun.

DO NOT use these on a blued gun....it also removes bluing NOW.

For normal cleaning a good stainless or coated rod, BRONZE (NOT stainless) brushes, patches, and whatever bore solvent you like is best.

Flitz ought to take it off also.

:thumsup Flitz is great stuff, but a very gentle application and wipe on stainless, as you can polish the stainless if you don't go easy.

If this is a working gun I would not worry about the "burn/lead rings" at the front of the cylinder. I've got several revos that are like that and they in no way affect the reliability of the gun.

They may be esthetically unpleasing to the eye based on what the gun looked like new, but the effort to remove them has never been worth my time or energy.

Make sure you take a toothbrush to the front of the cylnder where the rod and crane connect. If you spin the cylinder while it's opened and it spins freely, there is no build up in that area which, if ignored long enough can affect the cylinders free movement.

I understand that a lot of people want their guns to look new after firing when cleaning them, but the photo you've shown here is clean enough to ensure reliability. My revo cylinders look far worse than yours in that area, I just don't worry about it on a working gun that's going to be shot again and have the same issues the next time I fire it.
