I took my reasonably new (Less than 6 months old, less than 50 rounds through it) 870 Express Tactical skeet shooting over the weekend. I had a heck of a time getting it to extract every once in awhile. Seeing as I bought it as a predator defense gun (I'm a farmer), jamming is exactly the opposite of why I bought an 870!

After checking the interwebs it seems that this is a very common problem with poor machining of the chamber. I pulled mine apart and the side opposite of the extractor is galled and as rough as hell. VERY poor machining!

Seems the fix is to pull out a Dremel tool and give it a polish.
Video of the fix here: https://www.youtube.com/watch?v=mlGoxNsaieE

Now my question for you wise gents, is this; what are the chances that Remington will stand behind their product? Or should I just forget it and fix an obvious factory defect myself?
 
From what I hear they will take care of it. But do you want to be without the gun? I polished mine and it took 1 minutes. Go gentle. Just a polish. And then shoot it. A lot! that will help to.
 
I had the same problem and fixed it myself. I wrapped some oiled steel wool around a wooden dowel and scrubbed the chamber like crazy. Have shot 500+ rounds since without an issue. Might be worth a try before you break out the dremel!
 
I am a certified Remington 870 Armorer. That kid doing the fix video is out to lunch. He cannot even explain correctly the extraction forces. All your gun needs is some wire wool wrapped around a 12 ga brass brush and some Flitz or other metal polish (no grinding compounds) run this in the chamber for awhile to polish the walls. I run it with a drill until some warmth can be felt through the outer chamber area. That will fix it. It is the brass washed steel case head that is sticking NOT the plastic hull. A second polish may be necessary but I have yet to need one. I have fixed about 20 Express guns this way. Sending it back works but it takes a while and it is a simple fix. I own a 870 Express and I endorse this message.

I found the faster I eject the universal shells after firing them the less they stick. About half a second.
After 2 or 3 seconds of an empty shell sitting in the chamber they would start to stick.
I use Federal and Challenger in my Magpul Express now with zero issues. No polishing done either.

I found the same thing with my 870. It will jam depending on the ammo I'm using, mainly lower cost slug shells. If I use higher quality shot, or those beautiful rifled slug shots that cost about $1.50/ea, I have no issues at all. Still, it's good to find a solution to this so I can blow off the cheaper ammo when I'm out having fun.

I'm suspect I'm just a dummy, but would you mind explaining exactly what you mean by "running it in the chamber?" My Norinco 870 clone sticks in on ejection in what sounds much like this problem. I'm not clear on how exactly to access the "chamber" with the 12G brush. Are you saying to remove the barrel and polish the point at which the brass on the shell contacts the interior of the barrel? (I'm thinking the answer is yes, but it's better to ask..)

Thanks for the help!
 
Had the exact issue with an express 870; used a 1/2 wooden dowel with a slit cut approx 1.5 deep in one end with some brown scotchbrite pulled into the slit. Had enough hanging out each side of the dowel that it would spin with a little drag in a 1/2 drill and not create too much heat or stall out drill. 2 min later it was fixed and will cycle any shells now.
