JB’s Bore Paste & ARs
- Thread starter 232593
- Start date
I think there are plenty of guys that have used it with their AR's and at one time I think Armalite even recommended it for their break in procedure. I don't think it's necessary though and it would probably be pretty easy to mess it up and trash a barrel that's otherwise pretty good.
For reference Frank from Bartlein shows some good examples of this in his thread:

For the Love of God, GI Joe and John Wayne.... cleaning and abrasive cleaners
Guys..... This has been beaten to death but you have to watch how your using abrasive cleaners! Here is a 223 barrel with 800 rounds on it. Cleaned after every 75 rounds fired. I know the pitting is from a chemical reaction but I didn't get the whole story. It was cleaned approximately 10-12...

A blast with compressed air or brake parts cleaner will clear the port and it can then be pushed out the bore with another patch.
Easily confirmed with a borescope
Well, without getting into whether you should be using it at all in the bore of your barrel, if I had an issue that I felt using the bore paste would cure; I'd just turn off the gas. Loosen the gas block and move it forward enough so that the port is covered. Run it as a single shot, then blow air through the gas tube into the bore and swab it out.
I wouldn't want an abrasive running through my gas system. Not because I know it's a bad thing to do, but it sure seems like it can't be good.

Frank uses the blue JB as needed. NOT the red. Edit: he also uses Remington 40x.
Sounds like maybe you are thinking of a process similar to the Tubb Final Finish bullet? Described as “lapping and burnishing bullets”. Perhaps I’m wrong?
FinalFinish® & FinalFinish® TMS Bullet Kits
By using David Tubb's FinalFinish & FinalFinish TMS Bullet Kits, you will experience better accuracy, reduced fouling and easier barrel clean up.

With the blue JB paste, you don’t shoot anything through it. Rather, you use a spear jag, a Parker Hale jag (Frank’s choice, I believe), or a worn brush wrapped with a patch coated with JB on a cleaning rod and push it up and down the barrel.
You only do this occasionally, like for a carbon ring or when regular solvents aren’t doing the trick.
Then you make sure all of it is gone from the bore before shooting.
Some time ago I decided to stop researching bore cleaning a now I just copy Frank. My maintenance life is much more zen. Lol
Attached is Frank’s method. He doesn’t mention JB Blue in the pdf (just Remington 40x), but often mentions it on this site, like here:

DO WEAR GLOVES when using DMSO. We used it to treat issues/injuries to performance horses legs. Powerful stuff. Anything you touch with your hands that has any type of substance and also has DMSO in it, will be in your bloodstream. The old test. Put some lemon or orange juice on your palm...

JB bore paste + Kroil is awesome for getting tough carbon fouling out of barrels. I'm a Wipe Out guy myself (I only use patches) and that does a great job getting most things out, but after about 1000 rounds, carbon gets burned into the bore and patches won't cut it. I use VFG pellets with JB+Kroil combo. Works like a champ. I used a Teslong borescope to figure out what works and when it's needed. I don't use brass or plastic brushes on any of my rifle bores and only use the JB with Kroil when needed.... just like Frank says.
Carbon ring formation is one of my concerns. I switched from Ramshot TAC to ARCOMP in 5.56. ARCOMP yielded much better and temp stable results. BUT, from what I’ve seen so far it is quite a bit dirtier than the TAC. So I have a hunch that it might be more prone to carbon ring formation.Frank uses the blue JB as needed. NOT the red.

I’ve heard of Wipe Out damaging barrels and causing pitting. @FredHammer I believe had an issue with it resulting in his barrel getting ruined.
That's all I shoot is AR rifles. Wipeout has never shown any bad side effects on my rifle bores (looking at them with the borescope), but then again, they are mostly stainless or chrome lined.
My Bartlein has been cleaned almost exclusively with Wipeout for the last 3 years and it still looks great other than normal wear in the throat area.
Wipeout/patchout is probably fine. I used to use it. But I had heard about isolated issues and did some research. I’m wondering if there were some bad lots at some point?
WTF barrel worms?
I have a Bartlein 6br, it's cut for a origin, put it on a solus for my nephews Christmas present this year. Had 400rd on it when purchased according to seller. It has some barrel worms. I used some thoroughclean on a iosso blue brush, and got rid some, reduced size of others. But OMFG I USED AND...

My bottles are at least 8 years old if not older. I have been down in NC for almost6 years and they moved down with me and I had them for a while before that.

I've used the JB Blue Bore paste for years, Frank White was a big supporter of it.
I switched several years ago to the KG line, works better for me.

For cleaning after the powders that tend to accumulate carbon faster, JB blue. Smear it into a patch wrapped around a worn bronze brush or mash it into a VG intense pellet, and wet either one with Kroil or Free-All.
I have been using the blue JB paste the Brian litz way (and before that I think it was the winning in the wind guys method) on a carbon rod with patches to wipe out my white oak barrel, criterion’s, and a Grendel Hunter every 200 rounds. I haven’t seen any issues yet. It saved a 18 inch 6.5 criterion’s accuracy for me. I wouldn’t use a brush with it. Before I cleaned a barrel without a gas block I didn’t even realize it was getting paste in the tube and port hole but it never caused a malfunction, I’m 3k rounds in to the white oak AR barrel and it has ran fine 110 degrees down to -10 frozen left outside no issues with my ammo.
Just don’t use a brush with it in the barrel. The patches on a rod will clean the barrel back to shiny and bright you don’t need a brush in the barrel. The JB on the patch will usually clean it up good and you can usually just put a patch on a oversized brush that won’t go down the barrel and twist it a few times to get the chamber mirror shiny again.
Blue JB. Patches. 30 strokes, replace patch, 30 strokes, patch out barrel with a Kroil soaked patch, good to go.
In addition to other things, I’m hoping that it will do for my 24” 15 year old Stag Varminter what it did for your 18.5 criterion. The Blue JB & Kroil did an excellent job cleaning EVERYTHING out of a .375 CT HTI barrel.
Did that cleaning regimen. Bore scope did not show any paste in the gas port. Hopefully I can test it next weekend and see if the accuracy improved like your barrel did.
