Most aggressive bore brush > Maintenance & Cleaning

Posted: 7/17/2006 8:18:57 PM EDT

Alrighty folks, I don't want to thread-jack.

There's an ongoing thread in this forum where a fellow member has noticed stubborn fouling just forward the throat in his chrome-lined barrel. I too, am having the same problem.

I have thrown every cleaning solvent/brush in my arsenal at my LMT 16" M4-type upper.

- Sweets 7.62 (multiple 10min soaks, flushed with MPro7)
- MPro7 (multiple 30min soaks)
- Hoppes #9 (two eight hour soaks)
- Armadillo Blue Wonder (three 20min soaks)
- FP-10
- Slip2000 Carbon Cutter
- Slip2000 CLP

All of the above have netted hardly if any improvement in the removal of the offending fouling.

I do notice that after the two Hoppes #9 soaks that patches came out black with some blue/green in it.

Now, on to my question.
What's the gnarliest, most aggressive bore brush?

Thanks in advance,
-Jim

You might have pitting if those solvents did not work. Have a gun smith look at the bore with a scope to be sure.

Stainless steel brushes, but i recomend you do not use them.

Dewy Bronze brushes are all I use.

Try a bronze brush with JB Bore Paste.

The paste has a mild abrasive which shouldn't hurt the barrel.

Make sure to clean out any remaining residue and re-oil before storing.

+1. Just wrap a patch around a worn bore brush, add some IOOSO Bore Paste or JB and short stroke it back and forth. That should remove the fouling.

I'm not sure bore paste on just a brush works that well, you need to add the patch. JMHO.

This should do it.

If it's that stubborn, I would suspect throat erosion. Let a gun smith check it out to see if it's time for a new barrel.

Hey folks, thanks for all the pointers.

I'm definately having one of my local 'smiths take a look at the throat with a borescope sometime this week.

I'll see what the verdict is before the JB Paste.

Thanks!

Duke...Let us know what the verdict is on the bore scope inspection. I can't imagine mine being pitted or eroded after only 2400 rds but it is possible. Though I did do some rapid fire I never abuse just for the sake of abusing. Maybe 30 rds rapid fire then let cool for awhile before doing it again. Never 10 30 rd mags nonstop as a torture test. I soaked again and got a little more out but I will new some new bore brushes as mine are all shot.
I will keep Y'all posted on the final verdict after I get some new brushes and soak/scrub again. str8shot 731

^^^^^

I'll most definately let you folks know the outcome of the borescope.

How's your barrel fouling treating you these days?
