extractor issues. AR15

[Blind Sniper]

I saw that exact same damage on a Wolf steel casing that was stuck in a friend's AR. The cause of his problems? A shitload of fouling buildup caused by a four-digit round count and him not knowing how to field-strip and clean the rifle. When I dropped the firing pin, it was completely black with sludge. Took an hour just to get the BCG and barrel clean, chamber took half an hour. Once I did, though, the gun ran flawless for the next 38 rounds (18 Wolf, then 20 M193).

The recovered casings have absolutely zero marks on them other than a nice firing pin indent in the primer.

Wow

Could be.
Probably is.

Field stripping and cleaning is optional in some people's minds. I have two friends at work that had never cleaned their AR's.
Incomprehensible to me, coming from .mil, but perfectly acceptable in their minds.

Does an unfired factory round extract and eject cleanly (do this only after removing firing pin)?

No offense man but this is really bad advice. See http://www.texasguntalk.com/forums/rifles/50966-ar-owners-learn-my-mistake.html for how I nearly ruined my AR doing this.

Do you see velcro on ejection port ? That will fix the issue apart from cleaning and other solution provided here.

Most likely overgassed.

As a soldier in a combat arms mos,unit armorer, weapons cadre for unit and someone always in a terrain that hates weapons i can say with 100% pure unscientific fact but personal experiance that field stripping and cleaning is not only worthless to a certain extent but harmful. I cant give you the extact data on one of my personal ar15s but it hasnt been cleaned in several years and functions perfectly fine. The reason? Its all in the lube, ive been using froglube since it first came out and was just barely getting on the market and only by word of mouth. If you use any kind of issued clp then i agree 1000% that regular cleaning is needed. That crap they give us is pure junk and isnt worth a cent.

I have turned on multiple others to froglube including other soldiers and leo's. When they see how clean my weapon is compared to theres after a similar round count or much higher they definately convert.

Maybe check the extractor spring/rubber insert.
I have ran into a bad batch of extractor springs recently that were not heat treated correctly and collapse over time.
They work at first but they soften up pretty quickly to the point they don't hold at all.

Look at your brass and see if the extractor has a good hold on the rim or if it's not engaged completely and pulling just the edge of the rim back - if it's on the edge, check the spring.

I know this is a "maybe" thing but those springs are cheap!

Hope that helps you out friend!

How does velcro on the brass deflector cure FTE problems that nearly pulled the rim off of the brass?

It doesn't.

At all.
