I have a ruger lcr I have had since since 09 and I have found marks above the barrel shroud which I thought was carbon build up. I have tried clean it with everything under the sun and it will not come off. There is also a small line forming above the barrel shroud that you can see but it's faint. Anyone have any issues like this? Should I contact ruger?

What cleaners have you tried? Post a picture of the area of concern, maybe.

Clp,hops,rem oil, and for reason a
Brake cleaner.

Be curious to see pictures as well. I've had a LCR 357 for several years and haven't noticed anything like you're describing.

I can not get this phone to focus on it. It looks carbon build up with a small line going through it. But the stuff that looks like carbon will not scrape off.

Can you get that section of it soak in a carbon killer like Slip 2000's version.

I do have some slips 2000 and I will try itif ruger finds nothing wrong. I got an email back from ruger and they want to see the gun. Guess I will just let them look at it. It's my carry gun when I am at work, so I prefer there be no issues.

I would saturate a patch with Slip 2000 carbon cutter and lay it on the area overnight. I'm not surprised the stuff you tried was ineffective.

I assume the barrel/cylinder gap is within specs (not excessively wide) and even (not narrower at the top than the bottom or vice versa). All revolvers, discounting oddities like the Nagant, are subject to this. Anywhere hot high pressure gas, sometimes particles of unburned powder or off the bullet, escapes is going to leave a mark on the metal. It is worse on aluminum than steel because aluminum is softer. In all likelihood, this will be self limiting and not get any worse.

What egregore said. Flame-cutting is self-limiting. Perfectly normal especially for hot magnum loads. Not to worry.

Adios,

Have you shot a lot of lead based or non jacketed bullets? Could it be a deposit of lead there? I get a little on my Ruger Single six after about a brick or so through it. It WILL scrape off - just takes some work. I've sharpened a brass rod for the job.

Actually, Ruger did have some LCRs that had that problem, notably with +P loads. Talk to them. They'll make it good.

ruger said it was flame cutting and it was normal. no need to send it it.
