AR brass not ejecting

[vmassarano]

I have an A-15 chambered in 6.5 Grendel. I've put less than 1,000 rounds thru it so far.

The last time I took it to the range, a fresh round jammed against the spent round. I cleared it. Then the next round fired off, and the following two rounds tried to chamber at the same time. The first got jammed into the breach when the second one came in right behind it. I cleared those and gave up for the day. I took the AR home and gave it and the BCG a thorough cleaning and lube.

I took it back to the range today and every spent round jammed against the next fresh round in the port before it could be expelled. Any ideas? Do I have a bad extractor??

Sounds like extractor spring....or dirty chamber. If you have a non-chrome lined barrel, rust can developer in the chamber and cause extraction issues like you describe.

This happened in the early fielded versions of the AR-15/M-16 in the humid, wet, conditions of S.E. Asia.

I would start with pulling the extractor, cleaning it, and inspect the spring or replace it.

Are you shooting Wolf steel cased 6.5 ?

+1 for bigBamBoo my first thoughts when I read your post. Sounds like extractor spring.

One of the easiest troubleshooting technique is to load the mag with one round, charge the round, fire, and make sure the BCG locks back. Then repeat with two round in the mag.

If there is a fault, it will avoid compounding the issue to help isolate the root cause.

"BigBamBoo" & "heyasiankid": I'm also leaning toward the extractor spring. After disassembling and cleaning the bolt, the extractor itself looks undamaged, but the spring looks a bit flattened. Would it more sense to buy a new extractor or just the spring?

"baih777": I'm shooting only the good stuff - - Hornady Black 6.5 Grendel.

"walmart_ar15": That's exactly what I did. I loaded one round at a time in one of my mags, and then fired it off. Over and over, the spent round wouldn't eject. Finally, I loaded two rounds and the second round jammed the spent cartridge in the breach. Had to bring the rifle home to tap out that spent round with a wood dowel.

That's a great idea to just load one round at a time. If the case is sticking then try a good chamber brush, in addition to a new extractor spring. You might also try one of those extractor donuts that add some pressure to the extractor, you might even need a new extractor. Other things to check for is a weak magazine spring. If you have 1000 rds into it, then you might have a worn buffer spring (main spring) that is allowing the bolt to bounce.

"colt11": The stock and buffer spring were replaced a few months ago to meet CA featureless requirements. The rifle was working just fine with the new stock. I think the problem may have started when I cleaned the extractor not long ago and the spring (+ donut) came off. I put it back in place, but now I'm wondering it I got in backwards. Checking / replacing the extractor donut and using the a chamber brush could make a difference. Thanks.

So fail to eject with just one round. Did it lock back? Sounds like the case is left inside the ejection port. LOL kinda of silly with this type of failure to try two rounds ... Just giving you s.... haha...

Does the round eject normally when you hand cycle the action? If it does not, then yes focus on the extractor claw, spring and the donut washer. LIke with anything, they will wear out (but typically more than 1000rd) Another thing to look at is the ejector. Make sure the ejector spring is plenty strong to throw the case out. Yes, AR ejection is by a spring plunger. If too weak, it will just drop the case inside the ejection port.

So another way to check to see if it is the extractor or the ejector, is do the same one round routine, but this time without the mag fully inserted. This will prevent the lock back and let the bolt go forward. If the BCG get jammed with the case pushing against the chamber, you may have a ejector problem, now if the BCG closes with the empty case sitting back into the chamber, then most likely you have extractor problem. This test is not 100%, but can help narrow it down.

Clean the chamber with solvent.
Change the extractor and spring. There are some kits that come with a o-ring instead of a spring.
Buy two sets. Always good to have a spare.

It could also be the ammo. A different box from a different lot # could be hotter causing the case to get stuck.
