Dirty AR bore?

I have a Stag lefty upper that I built. Very happy with it...no issues, but cleaning it is a chore.

After shooting a couple of hundred rounds through it, it takes a lot of patches before it's even remotely clean. I'm using the G96 solvent, and usually I run a couple of saturated patches through to soak the bore and take out the loose stuff first. Let it sit a few minutes, then give it a dozen strokes of the brush (tornado brush). I follow it up with a bunch of patches wet with solvent, repeat the bore brushing, and then follow up with more solvent soaked patches.

I've never been able to get the patches to come out "clean". After a few dozen patches, when they come out light grey, I give up and run a few dry patches through, then some gun oil.

Doesn't seem to matter if I'm using cheap MFS ammo, or the better stuff. Is this normal?
 
You have to clean the bore with an ammonia based product. I use Kroil mixed with ammonia.

G96 will take care of the carbon and lubing but not the copper build up.
 
I tried some Pro Shot 1 Step Bore Cleaner tonight too...same results. It's supposed to get rid of copper fouling...maybe it's just not strong enough? I chose the G96 and Pro Shot because of the low odour...maybe the stinky ones work better?

Thanks for the tips so far.
 
Some of what you're experiencing is not bore fouling.
Sometimes you get your bore squeaky shiny clean, but they crud that keeps coming out on the patches is getting picked up from the flash hider on the way out, or the chamber on the way in.

I make a point to clean my chamber. I use a 30 cal patch, soak it, and get the chamber wet, then spin an ar chamber brush in it, then 30 cal patch it out again, and sure enough, that patch comes out as black as when I started cleaning the bore despite the fact that the bore is shiny. Tends to clean up faster tho.

You want to see something scary ? Remove your flash hider after a couple grand rounds and see what your crown looks like.
 
But yeah, you'd going to get a lot of advice, but you have to make a judgement call of your standards. I find with some of my guns, I have to draw the line at how much time I'm willing to spend cleaning them. Sometimes even when the patches come out white, run your brush thru' it, and the patches come out black all over again.

Unless it's a precision rifle that groups sub-moa, your gun should be happy with the current effort you are making.

That's the whole idea (unless you like literally running dozens and dozens of patches...) 2-3 quick yanks of the snake and you're done! ;)

So I should get a boresnake? It takes quite a few patches to clean out my barrel, the frog does such a good job at breaking up the carbon more and more just comes off.
 
When I was in the army we found that the C-7 bores would seep carbon when stored. Before ATI we would clean them and leave them bone dry . I don't know if CLP was to blame for this or something else.
 
I seem to be acummulating cleaning agents, but, what I've settled on is using something that isn't a lube/protectant for the initial cleaning, and, once satisfied, I finish wi th one. Either G96 or Gunzilla. I've gone back to using hoppes solvent for the initial cleaning. They have a new extreme line that is considerably less aromatic.
 
What's the point of regularily cleaning an ar? Just lube it until you start having ussues.I have a few thousand rounds through mine with only lubinng the bolt with clp. No issues at all.
 
I thought that we were talking about fireball's mind there for a second.
:p
Then I seen that this was a serious question so...
Time to get some pads:

Brushing works good too ;)

Conte...point well taken. I've thought of that too, and I actually clean out the chamber and flash hider...so I'm pretty sure the black stuff I see is coming out of the bore. I use a chamber brush like the second picture in Uncle Tom's post.

My rifle runs fine and groups well...maybe I will try something stronger for the initial cleaning and see if that makes a difference. I just thought I'd ask since all the cleaning instructions that I've read or seen on video advise to run the patches until it comes out clean...a virtual impossibility from what I've experienced so far...lol. I do have a bore snake, but with the .223 being a fairly small bore, sometimes running that string through can be a PITA.

Thanks all!
 
I use foaming bore cleaner, let it sit for 30-60 min and then clean it out with an oiled patch on a jag… the patch and jag are a fairly tight fit… if I think it needs it I will repeat… I try not to use the bore brush unless absolutely necessary, and sometimes I will run some Hoppes solvent down too, usually only if I am using the bore brush… although, I have gotten my best results with the foaming bore cleaner and a tight jag, surprising results actually… considering how easy and how well it works, I would have to suggest it… and yes, I get fairly clean patches by the end...
