Bolt face brass fouling

[sentry1]

I recall reading some info that mentioned fouling in the gun is a bad thing.

The bolt face on my M4 never looked like this, so... Is this a problem I need to look into, or do I just get some solvent and scrub?

Edit: Was trying to do accounting homework and post at the same time, totally thought that was copper in the bolt face for a moment.

A Qtip and some solvent and wipe it on and wait a little and wipe again. It will wipe it right off. It's normal. My rifles have looked like their bolt faces were made of brass some times.

Not an issue. Don't worry about it.

Re: Bolt face brass fouling

most boltface is a little rough so when you turn the bolt handle on a live round it "files" a little brass. Nothing to worry about one bit, all my bolt actions do it, work just fine and I never cleaned the bolt face after several thousand rounds, not anal enough I guess.
