Carbon remover

With experience, you will develop a sense of “feel†when using abrasives pastes. This requires a high quality rod with rotating handle along with a tight fitting patch on a jag. The effort needed to short stroke the patch down the bore will ease up as you progress. You will be able to feel the bore smooth out as you go. This is the method I use after I have scrubbed the bore with a bronze brush and conventional solvent (Hoppe’s #9). It helps to have a good selection of jags and patches to achieve a proper fit.

Powder fouling will show up that way. Hard carbon will not. Ask anyone with a bore scope who is familiar with this issue. One way that you can detect it , is to start dry patch (after completing a thorough normal cleaning) that is a snug fit, but which can be moved in the bore without pounding on the rod handle, pushing it up the barrel for a foot or so, and then slowly draw it back holding the handle very lightly. If it hangs up even a little as the patch passes through the throat, you may have a build up of hard carbon in that area that some careful short stroking with IOSSO should get rid of.

Carbon is only found in front of the cartridge in the chamber and barrel, that is byproduct of powder fouling caused from repeated combustion temperatures (+3500-F). It is a crystalline burned ash that will always look brown on a patch, and is distinctly different in color then powder/primer fouling (black/grey).
The fouling of your AR bolt is blow back powder/primer fouling and is not carbon.

I am no expert but isn’t “Carbon is only found in front of the cartridge in the chamber and barrel, that is byproduct of burned fouling caused from repeated combustion temperatures (+3500-F).†just “powder/primer foulingâ€. I realize it is not blow back, but is it not the same stuff deposited just in a different area? What I am saying is the carbon does not come out of thin air but all the carbon in the barrel comes from burning the powder and primer.
Where does this "crystalline burned ash that looks brown" come from if not powder/primer?
I do have a borescope and the carbon I see in front of the chamber before the lands looks black to me.

As I wrote, carbon is a byproduct of burned powder fouling being repeatedly "burned" and added to from combustion of fallow-on shots.
A 223 (your AR-15) is not a known carbon prone cartridge, and are not known to carbon very often.
It would not surprise me if you have never seen or experienced true carbon layer in your AR15's, for that very reason.

After reading this thread and realizing that I am serious about getting more serious about the sport I think I am going to spend the money I saved for a custom action on a Hawkeye Borescope. I know this is probably not the best idea on the planet but it seems the only way to know for sure without question what is going on in the barrel of your rifle. Not just for cleaning but for other uses and for other shooters rifles. Ill take it to matches and let anyone there use it but this thread sealed the deal on it for me.....GOTTA HAVE ONE.

You are correct, it is one of the best methods to know for sure what is going on inside your barrel. When I got my Hawkeye Borescope it caused me to change my cleaning routine for the better. It also takes some use to know what you are looking at. Be careful with your Hawkeye it is a very delicate instrument. I said this because of your statement, "I'll take it to matches and let anyone there use it". It will not take much to damage it, especially the mirror and the repairs are very expensive.OIF/OEF said:

Because of stock comb clearance issues, I prefer to look at barrels that belong to glue ins off the action, and those that are part of bolt ins with the barreled action out of the stock. When I use mine, I set up the barrel or barreled action on the left side of a table. For a loose barrel I use a low torque barrel vise clamped finger tight to keep it from rolling around, and stack magazines under it as needed to level the bore at the desired height. I use a right angle adapter, and let the light lay on the bench so that I don't have to handle it while I am using the scope. Then I very carefully feed the scope into the chamber and from that point forward start using the scope. I always make sure that I have run a couple of dry patches through the bore before scoping it, even if I want to look at a barrel that has not been cleaned. The mirror is first surface so that there is no glass covering the reflective surface. The tube is full of lenses. I would not turn loose of a bore scope at a match. If I had a very good table to set up on, and had the time, I would set up and after I had what the owner needed to see in the scope's field of view let him look with very close supervision so that he did not put the tube in a bind. For those who have much larger budgets, a video camera can be used and the image viewed on a monitor. This is the best way to do show and tell with a bore scope.
In .22 BR, a number of shooters use the VFG jag & pellets with IOSSO and scrub with a 12" brass loop rod to clean the chamber. Brownells is the exclusive USA dealer.
VFG Method: Install the VFG felt pellet and jag on the rod, and coat the felt pellet with J-B. Then use the same method – short-stroking the chamber and first 2" of the barrel – to quickly remove the fouling. For even better scrubbing action, use the VFG pellets with the bronze fibers embedded in the felt (#929-000-001).

When I first got mine I spent a lot of time examining every barrel I had. That was a good educational experience. Now that I know for a fact how to properly clean a barrel, I spend less time using the borescope on my guns. I know that my cleaning technique is effective and rarely inspect the entire bore, mainly just checking the throat area and first couple inches of the bore after cleaning looking for carbon build up and erosion.
If you get one you will soon become a valuable resource for your friends. I probably spend as much time inspecting barrels for my shooting buddies as I do my own. My brother collects old Winchesters and the borescope spends a lot of time with him as well. I can’t say that it has improved my shooting to any noticeable degree but it has paid off in more ways than I had imagined it would. And if I ever decide to sell it I’m pretty sure I could get most, or maybe all, of my money back.

Barrelmakers love customers with borescopes.
They also love the ones scrubbing the pizz out of their barrels with abrasives ;D A name that is often referred to is Tony Boyer. I wonder how many people realize Tony replaces his barrels every 300-700 rounds? Could that be due to the excessive use of Iosso or JB? If one is maintaing one's barrels, a carbon ring shouldn't be much of a concern. Old habits are hard to change ;Dbutchlambert said:
