I have an AR that has suddenly stopped extracting the spent cartridge. When I fire the action cycles, but the shell stays in the chamber. The action goes all the way back and tries to push the next shell in. When I look at the spent shell it has a notch on the "lip?" where is tried to pull the shell out. Is there anyone in the Jackson area that works on ARs?

thanks

You might just have a weak extractor spring..not sure what it would cost but that could be it.

Here's the spring only - http://palmettostatearmory.com/index.php/ar-15-05/upper-parts/ar15-extractor-spring-with-insert.html

Or the complete extractor assembly - http://palmettostatearmory.com/index.php/catalog/product/view/id/1127/category/314/

Yep...my guess is that would definitely be the cheaper way to go rather than take it to a gunsmith.

make sure you clean the shell chamber in the barrel... Use some type of breech cleaner dissolver..

Its probably some build up causing the hull not to eject.. Since the extractor is pulling a notch in the spent hull..

Here's a step by step to tearing down the AR and bolt. http://www.ar15.com/forums/t_3_7/456002_FIELD_STRIPPING_THE_AR15.html

A little hint: there are tiny little springs in some places that can be launched at least a mile if you're not prepared so be cautious during take down. This only really applies to the lower assembly.

There is a brush made specifically to clean the chamber. I think I got mine from Brownells.

brass as far as I know. No off brand ammo. I think what I am shooting out of it is Remington. I'll check this evening and let you know.

I m no expert by any means, but I read where if u shoot steel then brass w/o cleaning, it can make it harder to extract the shell. Steel doesn't expand into the chamber like brass does, so u get all the junk from the spent case into the chamber(makes a tighter fit with brass and crude). Good thing for me, my brother in law is in the military and can break these things down blind folded, so it makes it easier for cleaning. Good luck with your ar.

The bolt and extractor probably need to be cleaned, and you might need to replace your extractor spring and o-ring if it still has one.

Should look like this:

Bravo Company has a replacement kit you can buy:

Yes it probably does need those replaced, but I know my limitations and having had no one show me how to do that, it aint happening at my house. Where can I get it done?

I just did some reading, and learned to take the bolt apart myself. It is really simple to strip a bolt all the way down, and put it back together. You literally need zero tools. Look on Youtube, there may be a video on how to take it down, that would help you with the process. One thing that I would add though, take it apart on a white towel, that way you can keep track of all of your parts.

My thoughts are everything is ok except it needs to be cleaned very good with a chamber brush. If the shell case has a notch in it where the extractor tried to extract it and the shell is getting stuck in the chamber, that is the problem. I would clean it very good before I even thought about replacing anything. You can order a chamber brush or get one at Van's for a couple bucks. If you don't have one and are shooting a AR15, you need one. If you haven't cleaned it with one, that is going to be your problem.
