870 express not ejecting

Postby Patternmaster kid » Fri Jun 15, 2012 9:46 pm

I have a newer 870 express and can not get it to eject. I have tried multiple shells, also the extractor seems to skip over the base of the hull. But is it because the chamber is not polished? Any one have the fix?

Will it extract a unfired shell? Have you tried a previously fired shell? Is it really hard to pump after you fire it?

I would start with the polishing, if I'm reading your symptoms correctly. Have you tried different brands ammo?

Polish the chamber. Its easy and only takes about 20 minutes. You can research it right here on DHC. A pump should cycle anything. You won't believe how much smoother it will be.

That seems to be a very common problem with the express guns made after the late 1990s. A guy who frequents the shotgunworld forums has figured out what causes it. It's not so much the chambers that need polishing but actually where the barrel extension meets the chamber. After the shell is fired it swells up and the rim gets caught in a small groove where the rim recess transitions to the barrel extension. A couple minutes with a dremel and its good to go. I'd post a link but I don't know how to do it with my phone. Check around in the "I love my Remington" forum.

Its Very sad that a guy has to take a Dremel to a new gun to make it work. If thats the case Remington is in BIG trouble. :mad:

I had same problem tried fedral over winchester ammo and it worked well after that I did a good cleaning too. Try not to use to much oil as I heard this can be the cause of the problem too.

Hard to believe Federal ammo works over Winchester or Remington. I've never had much luck with Federal.

Actually, its either correcting an improper machine cut or its doing a finishing step that was left out by the factory to save costs. They got it right on the Wingmaster but not the express.

same here.

my ~2004 870 express had trouble ejecting 5-6 shells before I had a few hundred rounds through it now it has well over 2000 though and never misses a beat! but I am also careful to make sure the barrel is sinched down tight as it possibly can.

Back to the Express problem.
There's a thread in here where I posted pics of what needs to be polished.
The little cup thing in the barrel.
TRY that...
Here's a picture.
I took a brass brush (12 gauge) and stuck it into my cordless drill and used that to polish with.

My shotgun did the same thing. Would fail to eject and then stack two in the receiver. Sometimes it would let two shells come from the magazine and have the shot one stuck sideways in there. I thought it was operator error but...that can't be. I been shooting 870's since 1975 and suddenly a 1996 model gave me the blues. After I polished...no problems.

Can we get a bit more info on the polishing, maybe an after post (I assume it removes the blue, and the picture here isn't missing any blue).

I have the jam after firing symptom. I have also found that the ejector button (no idea what it's called, the little switch under the trigger guard) sometimes gets stuck "up" so I cannot press it, but if it's "up" (as in pressed) it should be ready to cycle. I'm guessing the jammed shell is keeping it from pumping.

Is this later bit a symptom? Thanks for all the help!

EDIT: I have tried Winchester, Kent, Hevi-Metal and Black Cloud, does it on all. At least once in 3 shots gets jammed, luckily I can get it out by really working to pump it (much greater force), but I think my shooting is suffering from that because I'm anticipating having to hard pump i, I missed 3 shots today on birds that should have been in the freezer.

go google "polishing chamber 870" you polish the inside of the chamber. and I f I were you I'd take out the firing pin assy. and clean then LIGHTY lube the trigger assy. as well then go test.

If you look at that pic Aunt Betty polished the barrel extension and he did the locking lug recess. You can see that there is still a ring of blueing left right behind the rim recess of the chamber. On some 870's that area is the culprit. Once the shells swell up after firing, the rim of the cartridge can actually get mechanically locked into rough machining marks.

That switch jumps up when you pull the trigger so its normal if you're not able to push it up when you have a fired shell stuck in the chamber. If its staying in the up position after the action has been cycled, then you have an issue.
